Taking a math test can be pretty stressful. Even if you know the material, you can still get the problem wrong. Knowing how to go through your math test and check your work can save you from handing in a test full of mistakes that can be avoided. ________1.________
Write it out
You can also check a math problem by writing everything out on paper. ________2.________ Writing out math problems reduces your chances of missing anything to the lowest possible level, which is a common cause of incorrect answers.
________3.________
Make sure your answers work by doing the opposite procedure of what your problem calls for, including the answer you got the first time around. In other words, you would use the opposite of this addition problem—subtraction (减法)—to determine whether or not your answer is the correct one.
Plugging in
You may find that a variable isn’t good enough or have a problem where you have to solve for a variable (变量). ________4.________ This is the only real way to assure yourself that the answer you’ve found is correct.
Check for a reasonable answer
________5.________ For example, if you get an answer in the millions and you know it should be in the thousands, you’ve likely misplaced a point. Go back through the work on your paper to make sure all of your formulas (公式) and calculations are correct. If everything looks okay, do the problem again and compare the result of the second try to what you’ve got on the first try.
A.Do the opposite
B.Correct the answers
C.Therefore you’ll improve your grades, as well as your math skills.
D.Plug the variable in the equation (方程) to check it out.
E. If the result of a problem seems to make no sense, it indicates that the answer is incorrect.
F. It also helps you to figure out everything after you have already finished the test.

How Writing Things Down Can Change Your Life
What do you write down? For most of us, writing consists of emails, task lists, and perhaps the odd work project. However, making time to write down certain things, such as our daily experiences, our goals, and our feelings can change the way we live our lives.
Here are five different ways that writing things down can change your life, and what you can do to get the most out of each.
1._____________________
David Allen, productivity speaker and author of Getting Things Done, recommends doing what he calls a “core dump”. This involves writing down every task, activity, and project you need to address. This could range from picking up milk on the way home, to a multi-person project at work. Writing down every “to-do” item you can think of clears space in your head for more important topics.
You can also use a technique called “morning pages”, which was pioneered by Julia Cameron, author of The Artist’s Way. Morning pages involves completing three pages (around 750 words) of stream-of-consciousness writing. Through doing this first thing each morning, you clear your head in preparation for the day’s most important thinking.
2. __________________________
Writing down what’s on your mind is a great way to work through inner conflict or process your feelings around a particular situation. It’s similar to talking a situation through with a friend, and it’s a useful way of strengthening your self-soothing (自我安慰)abilities.
3._________________________________
If you keep a journal and regularly write down your thoughts and feelings, you’ll soon have a record of your experiences that you might otherwise have forgotten. Keeping a journal can also enhance your levels of self-trust. When you can look back and see how successfully you’ve traversed and dealt with important decisions and tricky situations in the past, you’ll feel more confident in your ability to do so in the future.
4._____________________________________
If you write down everything you need to do in a particular day or week, you gain an additional sense of satisfaction, when having completed the task, you can cross the item off our list. Feeling productive enhances your productivity and fosters a sense of achievement and progress.
5.____________________________________
No matter what’s going on in your outside world, when you write things down, you enter a world of possibility, which helps you stay motivated and gives you space to think big and aim high. When you write things down, you have a chance to explore dreams and ambitions that you might not feel safe revealing to anyone else yet. You also have a space to keep track of all your ideas and desires so you can return to them later.

The Mississippi
The Mississippi is a great river whose relationship with man goes way back beyond its discovery in the 16th century.The River Indians used it as a highway and as a source of food, and it was they who gave it its name—“misi” meaning “great” and “sipi” meaning “water”.When the length of its branch, the Missouri, is added to it, the Mississippi becomes greater. 1..From the source of the Missouri to the tip of the delta (三角洲), it is 2, 480 miles long.
Great rivers are likely to suffer floods.In 1927 the Mississippi flooded 26 thousand acres, sweeping away farms, towns, everything in its path.In 1938 its floods drowned or killed 200 people and made millions homeless.Today the river has largely been controlled.2..
Industries have spread down some of the waterways of the delta, but otherwise the delta is a remote place, the homeland of a little colony of French Canadians that the British drove out of Nova Scotia in the 18th century.They still speak French, mixed with English, Indian, Spanish and Negro idioms.They keep to themselves, farming the rich soil of the delta.3..
4..Pioneers who first reached its banks wondered not only where it went, but what lay beyond.In 1764 the French founded a city on the right bank of the river, and named it after their king, Louis XV.This city, named St.Louis, became the jumping-off(起点) place for the adventurous men and women who opened up the Great Plains, and the way to the Far West.
Some 40 years earlier, at the beginning of the 18th century, the French had founded another city just above the Mississippi delta, New Orleans.5..New Orleans is one of the great ports of the world, and one of the greatest terminals for both sea and river traffic.
A.It was the Mississippi that made the city what it is
B.Levees, high banks built of earth, hold back the flood waters
C.Therefore, as we know, it’s the third longest river in the world
D.It is known that the “Great Water” has also been a frontier river
E.However, they paddled up and down the Mississippi in their boats to seek their fortune
F.The “Great Water” always remains a threat, for the streets of the city are below the level of the river
G.They call themselves Cajuns, who have actually been leading fairly primitive lives and preserving their own traditions

阅读下列应用文及相关信息,并按照要求匹配信息, 请在答题卡上将对应题号的相应选项字母涂黑。
首先请阅读下列图片及文字说明:
A. Drop-Bar Road Bikes
Generally lighter in weight than the typical mountain or comfort bike, road bikes are good for multiple pavement uses including fitness riding, commuting, long-distance/event rides, touring and racing.
Drop-bar handlebars are lightweight and aerodynamic and are a better choice if you want to go faster or are more concerned with efficiently transferring your energy into making the bike move forward. They also allow for a greater number of riding and hand positions than flat-bars. Their more aerodynamic riding position (bent over at the waist) may put more strain on your back if you are less flexible.
B. Flat-Bar Road Bikes
Flat-bar handlebars combine the efficiency of drop-bar road bikes with a slightly more upright riding position. This allows you to sit up in a higher and more relaxed position so you can better see the road and potential risks. An upright position also reduces strain on your hands, wrists and shoulders. This increased versatility comes with the tradeoff of being slightly less efficient (from an aerodynamic standpoint) than the typical drop-bar road bike.
C. Hardtail Mountain Bikes
Mountain Bikes are best for dirt or rocky trails and gravel roads; they are OK for pavement too (with tire change).
Hardtail bikes feature a front suspension fork and a rigid back with no rear suspension shocks. This type of mountain bike is much less expensive and lighter in weight than a typical full-suspension mountain bike. A hardtail is the more versatile choice if you plan to use it for both paved and unpaved surfaces. The tradeoffs from a full-suspension mountain bike? A hardtail is less able to safely handle more technical singletrack trails, provides less overall shock absorption and, in some situations, delivers less rear wheel traction.
D. Full-Suspension Mountain Bikes
Full-suspension mountain bikes have both front and rear suspension shocks making them ideal for backcountry trails or technical (steep, bumpy, twisty) singletrack. They also stand up to more aggressive riding including jumps or drops of up to 5 feet. As mentioned above, full-suspension bikes are more expensive and generally heavier than hardtail bikes.
E. Folding bikes
These bikes can be folded up and placed in a carrying bag, which makes them handy for commuters with limited storage space at home or the office. They are lightweight yet strong and can be folded up quickly and easily. Folding bikes are also a good choice for those who want to travel with their bike.
F. Electric-assist bikes
These bikes feature a battery-powered motor that can help you climb hills easily or make your commute less strenuous. Built-in sensors can monitor how much pressure you're putting on the pedals and then apply battery power accordingly.
以下是一些用户信息,请把图片与相关介绍匹配起来。
1. Tom is a bike lover. He wants to buy a road bike that can go fast on the road. Speed is important but it is more important for him to see the road and stay safe, since the road on which he rides is often full of traffic.
2. Jack is an office worker. Every day he goes to work by subway. There is still a long way from where he lives to the subway station, so he decides to buy a bike, which can be easily put at home, on the subway train and his office.
3. Peter loves making long-distance journey by bike. When travelling, he has to climb hills or ride on rocky trails, which makes him too tired to go. He wants to continue his journey even when he is tired, but he doesn’t want to travel by car or ride his motorbike.
4. Mark is a bike enthusiast who often rides in the mountainous areas. Unfortunately, his bike was damaged when he was riding on the mountain. Now he is going to buy a new mountain bike. Being a rich man, Mark doesn’t care about the price of the bike, but it must be tough and flexible enough to jump and drop on the mountain road.
5. Jim needs a new mountain bike that can be ridden on both paved and unpaved surfaces. It doesn’t need to be too expensive. He hopes to buy a bike that is lighter in weight than a typical full-suspension mountain bike

Read the following text and choose the most suitable heading from A-F for each paragraph. There is one extra heading which you do not need.
A. Factors that influence reactions to pollutants
B. Possible sources of indoor air pollution
C. Ways to identify diseases with similar symptoms
D. Long-term effects after repeated exposure
E. A commonly-ignored health threat
F. Immediate symptoms and regular treatment
1.Most people are aware that outdoor air pollution can damage their health, but many do not know that indoor air pollution can also have significant health effects. Environmental Protection Agency studies indicate that indoor levels of pollutants may be 2-5 times, and occasionally more than 100 times, higher than outdoor levels. These levels of indoor air pollutants may be of particular concern because most people spend about 90% of their time indoors.
2.There are many sources of indoor air pollution in any home. These include combustion sources such as oil, gas, coal, wood, and tobacco products; building materials and furnishings as diverse as deteriorated asbestos-containing insulation, wet or damp carpet, and cabinetry or furniture made of certain pressed wood products; products for household cleaning and maintenance, personal care, or hobbies; central heating and cooling systems and humidification devices; and outdoor sources such as radon, pesticides, and outdoor air pollution.
3.Immediate effects may show up after a single exposure or repeated exposures. These include irritation of the eyes, nose, and throat, headaches, dizziness, and fatigue. Such immediate effects are usually short-term and treatable. Sometimes the treatment is simply eliminating the person's exposure to the source of the pollution, if it can be identified. Symptoms of some diseases, including asthma, hypersensitivity and fever, may also show up soon after exposure to some indoor air pollutants.
4.The likelihood of immediate reactions to indoor air pollutants depends on several factors. Age and pre-existing medical conditions are two important influences. In other cases, whether a person reacts to a pollutant depends on individual sensitivity, which varies tremendously from person to person. Some people can become sensitized to biological pollutants after repeated exposures, and it appears that some people can become sensitized to chemical pollutants as well.
5.Certain immediate effects are similar to those from colds or other viral diseases, so it is often difficult to determine if the symptoms are a result of exposure to indoor air pollution. For this reason, it is important to pay attention to the time and place the symptoms occur. If the symptoms fade or go away when a person is away from the home and return when the person returns, an effort should be made to identify indoor air sources that may be possible causes.

They Just Can't Help It
My theory is that the female brain is mainly built for empathy — the ability to understand other people — and that the male brain is mainly built for building systems. 1. For example, women are more likely to read magazines on fashion and parenting, while men will choose magazines that feature computers and sport.
You may think that these preferences are influenced by the way people are taught to behave when they are growing up. However, this is not the case. A new study carried out at Cambridge University shows that newborn girls look longer at a face, and newborn boys look longer at a mobile. 2. It has also been observed that girls are better at noticing signs of changes in other people's feelings. Boys, however, seem to enjoy building toy towers and playing with toys which have clear functions. 3. People whose jobs are in the construction industries are almost male. Math and engineering, which require high levels of systems-thinking, are also male-chosen disciplines. Why do men and women have the difference? Actually women have four times as many brain neurons (神经) that connect the right and left part of their brains. Because of it, women have a better ability to multitask than men. 4. Men tend to focus on a limited number of problems at a time. They will separate themselves from problems and view tasks as independent from one another.
Some people may worry that I am suggesting one gender (性别) is better than the other, but this is not the case. My theory says that males and females differ in the kinds of things that they find easy, but that both genders have their strengths and weaknesses. 5. It is not true. The study simply looks at males and females as two groups, and asks what differences exist, and why they are there.
A. Generally speaking, there are clear differences.
B. Their preference for building systems may change over time.
C. You can see the same kind of pattern in the adult workplace.
D. They will consider many sources of information at the same time.
E. It is important to stress that the female brain may be built more for empathy.
F. That suggests certain differences between male and female brains are biological.
G. Others may think the theory creates a belief of what a particular type of person is like.

根据短文内容,从下框的A一F选项中选出能概括每一段的主题的最佳选项。并将答案涂在答题纸上相应位置。选项中有一项为多余选项。
A. Be optimistic
B. Stay close to friends
C. Act as if you are happy
D. Make somebody happy
E. Exercise regularly
F. Be grateful
Happiness is a choice. To be happy at all times, you need to make happiness a habit and not just an act. I believe that the following points will show you how to stay happy no matter what happens.
1.___________
Gratitude is a sign of appreciation and you ought to show appreciation for life. Always wake up every morning in acknowledgement that you have a list of things you should be thankful for, for example, I woke up this morning, I have food on my table, I have clothes to wear, I have a good paying job, the skies are beautiful and the atmosphere is great. By the time, I am sure that you will feel better already.
2.__________
Unhappiness can result from stressing our bodies and minds. Scientists believe that 20 minutes of exercise can make you happy regardless of how sad you may be. Exercise raises your heart rate. As your heart begins to pound, certain hormones(荷尔蒙)are released which create a sense of total well being and you begin to feel well again, the mind stress is gone and everything is under control. Another thing you can do is to take a walk; this works for me all the time. When you take a walk, you are able to think over matters that are bothering you and come up with solutions to them.
3.___________
“The best way to cheer yourself is to try to cheer somebody else up.” Said Mark Twain. When you sow happiness, you gain happiness. Mother Teresa knew this secret so well; she devoted her life to helping others even if it simply meant putting a smile on someone’s face. Here are two of her famous quotes: “A life not lived for others is not a life; let no one ever come to you without leaving better and happier.”
4.____________
Change is inevitable(不可避免的)and no situation is permanent. Whenever you are feeling sad or depressed, always remember that it’s temporary and that tomorrow will be better, tough times don’t last but tough people do. Develop a positive attitude, and you will stay happy.
5._____________
Smile always, even when you are feeling blue. When the body acts, emotions follow. A smile costs nothing but it creates much, it enriches those who receive it without making those who give poor. Learn to smile and act at all times, it won’t only make you happy, it will also win you happy friends.

Directions: Read the following text and choose the most suitable heading from the list A-F for each paragraph. There is one extra heading which you do not need.
A. Try writing with the wrong hand B. Let yourself daydream C. Develop your inspiration D. Discover your hidden talents E. Record your dreams F. Stimulate your senses |

1.
Every night, for about 90 minutes, we drift into a strange, shadowy, magical world of our own creation. Poets, writers, artists and even scientists have found inspiration in their “dreamland”. Dreams are a message from the subconscious, a way of tapping your inner self. Keep a note pad and pen by your bedside, and as soon as you wake, note down whatever snatches of dreams you can recall. Dreams can solve your problems, give you advice, reveal your true feelings, and be a source of inspiration.
2.

What are you aware of right now? Look at a familiar object in the room as if seeing it for the first time — explore it with your eyes. Next, listen intently to any sounds you can hear. What can you smell and taste at this moment? Touch whatever is within reach, run your hand over and around it — how does it feel? During the next few weeks activate all your senses. Visit an art gallery, walk in a pine forest, luxuriate in a second bubble bath, go to a concert, swim, have a massage. Try to experience it all as if it were totally new to you.
3.

If you’re right-handed, develop the skills of your left hand or vice versa — allow it to draw something, switch TV channels or drink a cup of tea. Try this exercise: write a list of ten adjectives which characterize your personality using the hand you usually write with. A few days later, repeat the exercise writing with the other hand. Then compare the two lists. You might be surprised at the secrets of your inner self! For example, on the first list you might have written that you’re “witty”, but the second list might say “suspicious”. Then try a similar exercise, making two lists of “ What I would most like to do”.
4.

Have you ever longed to paint portraits or watercolors, write a novel, draw cartoons, compose a song, design your own clothes, set up a business or landscape your garden? If so, why not start now? Yes, you might discover that your fast efforts are laughable — but try, try again. With a few notable exceptions such as Mozart, most people haven’t developed their creative talents through sheer hard work. Don’t kid yourself that you haven’t any spare time. It’s a question of making time, of seeing your talents as important enough to devote a few hours to each week. Who knows — you might be the next Laura Ashley or Agatha Christie?
5.

Forget about being told off for daydreaming at school. Daydreaming is good for you! Whether it’s a purely fantasy, or a dream about how life might be in the future, only the right-brain has visions of this kind. Creative visualization, vividly imagining whatever you desire as if it has already happened — and really believing in it, is said to be a powerful way of getting what you want. Many top sports people imagine themselves playing and winning — and it seems to work.
