When you are sitting in the car, do you ever ...

When you are sitting in the car, do you ever notice the drivers looking over their shoulders or side to side in the car? Well, they are doing this to check their blind spots! Blind spots take driving extremely difficult and increase the potential for car accidents.

Fourteen-year-old Alaina Gassler from Pennsylvania noticed her mother struggling with blind spots while driving their family car. So she came up with an ingenious solution that won the first place and $25,000 in the Broadcom Masters Competition.

Blind spots are the areas around the car that cannot be directly observed by the driver. There are two kinds of blind spots---on the back of the car that cannot be seen with mirrors, and blind spots at the front of the car as well.

When a driver is changing lanes, he has to look over his shoulder through the side windows to make sure that there is no vehicle in the blind spot. This invisible area is big enough to hide a car!

The other blind spot is created in the front by the A-pillar（柱子）---the material on either side on the windshield（挡风玻璃）that holds the glass and forms the frame of the car. In some cars, this pillar can be quite thick. Usually, people or cyclists can be hidden by this pillar.

Alaina's design was to get rid of the blind spot created by the front A-pillar of the car, the one that helps hold up the windshield.

She put a camera on the outside passenger side of the car which then sent the photos to a projector above the drivers' head. Then, she covered the inside of the pillar in reflective fabric onto which the image was projected. Basically, her device made the pillar "see through" and removed the blind spot on that side of the car.

Alnina's solution is very creative and could be improved by using LCD displays that will make it easier to see during day time as well.

1.What can be learned about blind spots during driving?

A.They call for careful driving. B.They make driving thrilling.

C.They are many in kinds. D.They can't be get rid of.

2.Which of the following can replace the underlined word "ingenious" in paragraph 2?

A.interesting B.creative

C.inspiring D.invisible

3.How did Alaina solve the problem?

A.By improving the A-pillar. B.By using a mirror on the outside of the A-pillar.

C.By relying on LCD displays. D.By using a camera to capture images.

4.What's the best title for the text?

A.An Introduction to Blind Spots B.A Warning About the Road Safety

C.A Teen's Creative Solution to Blind Spots D.Scientific Research on Blind Spots

Do you dream of the day when you can drive a car? In the United States, teenagers can get their driver’s license when they are only 16 years old, but it feels like forever until that day comes. Trust me, because I’ve been there.

1. But in my opinion, it’s worth it because it means having a lot of freedom. 2. and everything there is really spread out. So until I turned 16, my parents had to drive me pretty much everywhere.

There were several steps before I got that special plastic card. In Iowa, everyone can get their learner’s permit at the age of 14, which means you can only drive if your parent is sitting in the seat next to you.

3. In the state of Iowa, if you live more than a mile (1.6km) away from school you can get a school permit. You can only drive to school and back home. Luckily, I lived just over a mile away from school, so I was able to drive my mom’s car to school. 4.

Finally, after taking (and passing) a three-month-long driver’s education course and the final test, I was able to get my driver’s license. 5. It did in fact make life quite a bit easier.

A. I could almost taste the freedom already.

B. Still, on the day of my driver’s test, I was nervous.

C. The next step was to get my school permit at the age of 15.

D. Getting a driver’s license takes a lot of time and energy.

E. I’m from the rural state of Iowa that doesn’t have a lot of public transportation.

F. To many people, getting a driver’s license is a rite of passage (仪式) that involves a lot of luck.

G. But if you were caught going outside that route you would get in big trouble.

You might make a disgusted face when you notice that the person waiting in their car at the red light next to you is picking their nose,but admit it,you do it too.And while it might be the natural option when there isn't a box of tissues around,it can be bad for you.The main reasons people feel the need to pick their nose is to clear it of dried liquid,stop an itch（痒）,or just because it feels good.Boogers（鼻屎）form when dried liquid and cilia,the tiny hairs that line the nostrils（鼻孔）,trap the dust,dirt,and other things.When boogers build up in your nose,it can be uncomfortable,and sometimes just blowing into a tissue doesn't do the trick.

Otolaryngologist Erich P.Voigt,MD,told Business Insider that picking your nose can cause injuries and bleeding within your nostrils.That's not terribly damaging,but when the bacteria from your hands get into your body,it can cause a cold and flu.So doctors strongly suggest not picking the nose.

If dry winter air is causing the dirty liquid to harden in your nostrils,making you want to pick,consider damping the air at home,or taking a steam shower to soften things up in there.

Children,who are most famous for having a finger up their nose,sometimes don't realize how much injury they're causing,and sometimes it.can lead to nose bleeds.

So,next time you go to pick your nose,think about how many bacteria are on your hands and in your boogers, and maybe reach for a tissue instead.Even if you 're alone,and not waiting for the light to turn green,please,use a tissue.

1.Why do people pick their nose?

A. Because they want to disgust others.

B. Because they have the need to do it.

C. Because they have nothing else to do.

D. Because they don't have tissues around.

2.Which of the following can replace the underlined part " do the trick" in Paragraph 1?

A. act　　 B. work

C. play　　 D. help

3.Which can help people avoid a cold and flu according to the text?

A. Stopping nose picking.　　 B. Using tissues regularly.

C. Taking a shower every day.　　 D. Keeping the air wet at home.

4.What should you do when you have to pick your nose?

A. Be careful not to cause bleeding.

B. Use a tissue instead of bare fingers.

C. Wait for the light to turn red if you are driving.

D. Wash up your hands and clear your fingernails.

Did you ever notice that when you’re fat, men don’t look you in the eye? They look across your shoulder. There’s no eye contact.

My name is Leslie. I am a real person. Up until two years ago, I was never looked in the eye, by anyone.

I was too tired to be a lover to my husband. I was falling asleep by 8 o’clock most evenings. When I did go out for an evening，my husband was ashamed of me. And he said so to my face. When I walked, my thighs scrape together. I couldn’t even cross my legs. I was fat. Not just“overweight”Fat. I was 5’55” tall and weighed 205 pounds.

About 18 months ago, my husband Darrell left a “Dear Leslie”letter on my bed and asked for divorce.

I went to a psychologist for advice. I knew that my weight was the source of my troubles. But I’d tried 14 different diets, at which I failed one by one.

He listened carefully and recommended an entirely different program. This was not a “diet.”It was a unique new weight-loss program researched by a team of specialists who help to treat the severely fat. I entered the program. Within the first four days, I lost only three pounds. So I was disappointed. But during the three weeks that followed, my weight began to drop from 205 pounds to 124 pounds. To me it was a miracle.

The reason the program worked was simple. I was always eating. I could eat six times every day. I could snack in the afternoon. Snack before dinner. I could even have snack at night while watching TV.

How can you eat so much and still lose weight?

The secret is in the combination of foods, approved by the research team, which you eat in each 24 hour period. You will enjoy a variety of meats, chicken, fish, vegetables, potatoes, sauces. Even some light wine or beer if you wish. But be sure to have them in the right proportion（比例）…thus a complete 24-hour fat-reduction cycle is formed.

Without hunger, without nervousness, it lets you lose pounds so easily. Once you lose the weight, you’ll keep it off. Forever, I am sure of that.

1.Leslie________.

A．had never looked anybody in their eyes.

B．had difficulties in walking because she was too fat.

C．was looked down upon by her husband because she went to bed too early each      evening.

D．was often embarrassed because she was overweight for her height.

2.Leslie went to psychologist for advice in order to________.

A．lose her weight.     B．recover her marriage

C．get a vegetarian diet             D．become an advisor

3.The weight-loss program worked very well. The reason is that________.

A．Leslie ate very little food and sometimes even fast food.

B．Leslie only had snacks and never had dinners.

C．Leslie could have rich food several times a day in the right proportion.

D．Leslie had rich food whenever she felt hungry.

4.Where do you think this article is most likely to appear?

A．Daily newspaper.                  B．Women’s magazine.

C．Apart of a novel.                 D．Newsweek magazine.

Have you ever noticed the colour of the water in a river or stream after a heavy rainfall? What do you think caused this change in colour? It is soil that has been washed into the river from the riverbank or from t}le nearby fields．

Components of Soft

Soil is made up of a number of layers（层），each having its own distinctive colour and texture．The upper layer is known as the litter．It acts like a blanket．limiting temperature changes and reducing water loss．The topsoil layer is made up of small particles of rock mixed with rotten plant and animal matter called humus（腐殖质），which is black and gives the topsoil its dark colour．This layer is usually rich in nutrients，oxygen，and water．Below the topsoil is the subsoil，a layer that contains more stones mixed with only small amounts of organic matter．This layer is lighter in colour because of the lack of humus．Beneath the soil lies a layer of bedrock．

Soil forms from the bottom up．Over time bedrock is attacked by rain, wind，frost, and snow．It is gradually broken down into smaller particles in a process called weathering．Plants begin to grow，and rotten materials enrich the topsoil．Most of the soil in Eastern Canada．for example．Was formed from weathered rock that was exposed when the ice disappeared l2．000 years ag0．

Water Beneath the Soil

Surface water collects and flows above the ground in lakes．ponds．and rivers．Once in the soil or rock，it is called groundwater．Gravity pulls groundwater through the soil in a process called percolation（渗透）．Eventually the water reaches a layer called the water table．Under this is bedrock through which water cannot percolate．

As water percolates downward，it dissolves organic matter and minerals from the soil and carries them to deeper layers．This causes a serious problem because plants require these nutrients for growth.

Soil pH

Soil can be acidic．neutral．or basic．The pH of the soil is determined by the nature of the rock

from which it was formed．and by the nature of t}le plants that grow and rot in it．

The acidity of rain and snow can lower the pH of the groundwater that enters the soil．By burning fossil fuels such as coal，oil and gasoline，humans have been contributing to higher levels of acidity in many soils．When fossil fuels are burned．gases are released into the air and then fall back to earth as acid rain．Acid soil increases出e problem of carrying nutrients to lower soil levels．As nutrients are removed，soil is less fertile．Plants grow more slowly in acidic soil，and also become easily attacked by diseases．

1.The layer of soil that provides necessary nutrients for plant growth is called．

A．1itter    B．topsoil    C．humus D．subsoil

2.According to the text．which of the following is NOT true?

A．Soil forms from weathered rock on the earth surface．

B．The deeper layer of soil is darker in colour than t}le surface soil．

C．Air pollution is partially responsible for acid soil．

D．Groundwater tends to carry away nutrients for plant growth．

3.We can infer from the passage that the water table lies________．

A．between the topsoil layer and the subsoil layer

B．in the subsoil layer above bedrock

C．between the subsoil layer and bedrock

D．in the bedrock layer beneath the subsoil

4.The underlined word “dissolve” is used to express the idea that organic matter and minerals from soil are ________．

A．rushed away into the river

B．cleaned and purified by water

C．destroyed and carried away by water

D．mixed with water and become part of it

Have you ever noticed how hard it can be to find the right words? I have, frequently! And there are times 1. I am certain the right words do not even exist.

More than once I have been called to a hospital emergency room or to be with a family around the bed of a 2. (die) relative. And more than once I’ve been at a 3. (lose) for words.

4. wise doctor at a university teaching hospital once made a comment about comforting those who suffer. Someone asked the doctor 5. advice he offered his students, the future doctors, when caring for mothers who gave birth 6. lifeless babies. The doctor paused for a moment. Then he said, “I tell them they need two eyes. With one eye they have to check the drip. And with the 7. they have to weep. That’s what I tell them.”

That may be some of 8. (wise) advice I’ve heard. We may not always need to figure out what to say; we really only need two eyes. In Emily Dickinson’s words, “Saying nothing sometimes says the most.” It says I want to walk alongside them, difficult 9. it may be. My 10. (present) is something they can draw real strength and hope from.

An old woman diverted (转移 ) attention from the book when I was sitting in my car. She walked slowly towards my parked car with a large shoulder bag.
