Think about the longest elevator ride that you’ve ever taken. Whether you rose five or 100 floors, it probably took less than a few minutes. Now imagine riding in an elevator higher and higher as it climbs for nearly a day. When you reach the top floor, prepare for views that are really out of this world. You’ll be in space!
Space elevators might sound like a crazy idea, but they’re something scientists have been working on for decades.
At the moment, riding in a capsule is the only way ordinary people can get to and from space. But those rides are very expensive---about $ 25 million per person per flight. Now scientists are making efforts to reduce the expense of those rides.
Researchers are still figuring out the details about how a space elevator might work. One idea is stretching a very long cable — more than 37,000 kilometers — up to space from the earth’s equator (赤道). Objects in space above the equator orbit (绕……的轨道飞行) the earth at the same speed that our planet turns. A weight on the end of the cable would stretch it tight. An elevator tied to the cable could use it to climb up and down.
The only problem is that besides being long, this cable must also be very strong. Storms, including hurricanes might break it. One way to solve this problem is to stretch the cable from the moon instead of from the earth. Airplanes designed to climb higher than a typical jet might take off from the earth and link up with the cable, which would be held in place by the pull of gravity from the earth. An elevator car waiting there would then take riders the rest of the way to the moon. Fueled by solar power, the elevator could transport people and materials without much expense or effort per ride.
1.The first paragraph is presented by _____.
A. asking questions
B. analyzing causes
C. giving an example
D. making a comparison
2.Why have scientists been working on space elevators?
A. To make trips to space cheaper.
B. To help astronauts do research in space.
C. To find a more convenient way to the moon.
D. To prove an assumption which seems crazy.
3. The underlined word “it” in Paragraph 3 refers to _____.
A. the weight
B. the cable
C. an object in space
D. the equator
4. What may make the cable stay in place on the moon?
A. The elevator car on the moon.
B. The elevator fastened to the cable.
C. The pull of gravity from the earth.
D. The speed of the moon orbiting the earth.

You will spend hours at the gym training your body, but do you ever think about training your brain? Here are four ways to keep your brain mentally (脑力上地) active and healthy.
Play games
Your brain is a muscle just like the ones in the rest of your body. If you don’t use it, you will lose it. For example, doing a crossword puzzle (纵横填字游戏) once a day is a good way to give the brain the exercise it needs. This kind of puzzle is good at training different areas of the brain. But remember that when doing this puzzle, you should gradually increase the complexity (复杂度); otherwise, it will become repetitive (重复乏味的) and stop being mentally challenging.
Talk aloud
Although it might sound strange to you, talking aloud is a great way to boost your memory. A good exercise to try is counting to 99 in threes as fast as you can.
Be a team leader
If you find you can do your work very easily, you should find a new task. It is important that your job should be mentally challenging. Complex jobs are often more challenging and make the brain work a little harder.
Learn a language
A study found that, compared with those who could speak only one language, the people who could speak two languages had a slower rate of cognitive (认知能力) decrease. Learning a new language is very challenging and it makes sure that different areas of the brain have their lights on.
1.What is the main idea of this passage?
A. Why you should train your brain.
B. How to be a good team leader.
C. Training the brain is more important than training the body.
D. How to make your brain healthy and work actively.
2.Which word can replace the word "boost" in the third paragraph?
A. Change. B. Promote.
C. Decrease. D. Lose.
3.We should gradually increase the complexity when doing crossword puzzles because ______.
A. if we don’t use our brain, we will lose it
B. we should make our brain face different challenges
C. our brain is a muscle like other parts in our bodies
D. these puzzles can work on different areas of the brain.

Have you ever had a burger without meat? You might think that a vegetable burger will take away the real meaning of a burger as it will not have the juicy taste of meat. Despite these concerns, the company, Beyond Meat, has managed to successfully make plant-based meat.
On May 2, the company became the first vegan company to become public. Beyond Meat’s initial share price was expected to range from $19 to $21. Impressively, just hours later, Beyond Meat’s stocks rose to $73!
Instead of killing animals, Beyond Meat obtains these components from different plants and combines them to make vegan meat. It contains pea protein that gives the chewy, meaty texture along with canola oil, coconut fat and other binding agents. In addition, the company uses beet juice to simulate the bloody look of beef! The plant proteins are subjected to intense heating, cooling and pressure so that their structure becomes fibrous and copies that of animal meat.
For people who have changed their diet but miss the taste of meat, Beyond Meat satisfies their taste buds. It also has all the nutrients and elements that meat has, but does not come from an animal.
Plant-based meat is also beneficial as fewer animals are killed. As our world’s population continues to grow beyond 7 billion, so does the demand for meat. Livestock farming is not sustainable as it requires more land, consumes more energy and is one of the largest producers of greenhouse gases. Beyond Meat uses 99 percent less water and 93 percent less land. It also has 90 percent fewer greenhouse gas emissions, and it uses 46 percent less energy.
However, there are some people who do not like the smell of a Beyond Meat patty. Others question that processed foods are unhealthy and it is safer to choose whole vegetables instead. Regardless, with another company, Impossible Burger, looking to go public soon, as well as companies such as Tyson Foods and Nestle looking to enter the market, plant-based meat is here to stay. These companies hope to convince many people to switch from meat to plant-based alternatives.
1.Why did Beyond Meat’s stocks rise sharply?
A.People found it convenient to buy plant-based meat.
B.People believed the bright future of the company.
C.People preferred to spend more money buying meat.
D.People are becoming vegans in life.
2.What is the third paragraph mainly about?
A.What is made up of meat.
B.Why plants can be made into meat.
C.How plant-based meat is made.
D.Whether plant-based meat is allergenic.
3.What is one of the features of plant-based meat?
A.It makes farming sustainable.
B.It contains all the nutrients people need.
C.It doesn’t have the taste of meat.
D.It is environmentally friendly.
4.What can be inferred from the last paragraph?
A.Plant-based meat will become a new trend.
B.All people prefer plant-based meat.
C.Vegan companies produce unhealthy food.
D.The smell of plant-based meat is disgusting.

Have you ever considered all the English expressions that include words about clothes? Let’s see if I can name a few proverbs “off the cuff” since I haven’t prepared for it.
English expressions with “pants” |
People wear pants to cover the lower part of their bodies. We sometimes say that people who are restless or nervous have “ants in their pants.” They might also “fly by the seat of their pants” -- they use their natural sense to do something instead of their learned knowledge. Sometimes, people may “get caught with their pants down” -- they are found doing something they should not be doing. And, in every family, one person takes control. Sometimes a wife tells her husband what to do. Then we say “she wears the pants in the family.” |
When people want to say something about money |
Pants usually have pockets to hold things. Money that is likely to be spent quickly can “burn a hole in your pocket.” Sometimes you need a belt to hold up your pants. If you have less money than usual, you may have to “tighten your belt” -- you may have to live on less money and spend your money carefully. But once you have succeeded in budgeting your money, you will have that skill “under your belt.” I always praise people who can save their money and not spend too much. I really “take my hat off to them.” Yet, when it comes to my own money, I spend it “at the drop of a hat” — immediately, without waiting. And sadly, you cannot “pull money out of a hat” —you cannot get money by inventing or imagining it. |
English expressions with “shoes” |
Boots are a heavy or strong kind of shoes. People who are “too big for their boots” think they are more important than they really are. I dislike such people. I really do. You can bet your boots on that! Yet, truly important people are hard to replace. Rarely can you “fill their shoes” -- or replace them with someone equally effective. |
English expressions with “shirt” |
My father is an important person. He runs a big company. He wears a suit and tie and a shirt with sleeves that cover his arms. Some people who do not know him well think he is too firm and severe. They think he is a real “stuffed shirt.” But I know that my father “wears his heart on his sleeve” —he shows his feelings openly. And, he knows how to “keep his shirt on”—he stays calm and never gets angry or too excited. |
1.What is this passage mainly about?
A. Which words can be used to describe my father.
B. Why English expressions include words about clothes.
C. What people mean when they use some proverbs.
D. How to say English correctly and properly.
2.Which of the following proverbs are not related to money?
A. tighten one’s belt B. take one’s hat off to them
C. burn a hole in one’s pocket D. get caught with their pants down
3.Tim often considers himself the most important person in the world, which is far from the truth .We may say ______.
A. he “wears his heart on his sleeve ”. B. he “bet his boots on that ”.
C. he is “too big for their boots”. D. he “ fill their shoes”.
4.If you want to praise somebody for his calmness when facing danger, you may say______.
A. “Amazing! How can you keep your shirt on at that time!”
B. “You really fill your shoes”
C. “Awesome ! You wear your heart on your sleeve!”
D. “Cool! You are truly a stuffed shirt”.

If you’ve ever taken a handwritten prescription(处方) from a doctor, it seems that you can never make sense of the letters. Bad handwriting almost seems like a requirement for graduating medical school.
However, it’s not like only people with bad handwriting are attracted to the medical field. Ruth Brocato, MD, primary care doctor with Mercy Medical Center says she went from winning a handwriting award in grade school to having totally unreadable handwriting now. So why?
For one thing, doctors have to write more than just about any other job. Long days plus tons of writing equals a very tired hand. Most doctors’ handwriting gets worse over the course of the day as those small hand muscles get overworked, says Asher Goldstein, MD, pain management doctor with Genesis Pain Centers. If doctors could spend an hour with every patient, they might be able to slow down and give their hands a rest. But the fact is, most physicians are rushing around to the next patient. With so many patients to see in a limited time, doctors are more concerned with getting the information down than perfecting their handwriting.
The jargon (术语) that doctors deal with also lends itself to bad handwriting. For instance, QD is shorthand for a Latin phrase meaning “one a day” and TID means “three times a day.” Your pharmacist would know exactly what your doctor meant, but you’d probably just write it off as chicken scratch.
Now, doctors are moving toward electronic medical records to cut down on errors. No studies have looked into whether the yearly death rate from wrong prescriptions has gone down, but doctors agree there’s less chance for errors.
Of course, typing everything isn’t perfect either. There’s still the possibility of entering, say, 30 instead of 300. While we’re all for electronic medical records, we’ll write by hand whenever we can. Now, learn about these secrets hospitals don’t want to tell you—but every patient should know.
1.How many reasons are mentioned in the passage to explain why doctors are likely to have bad handwriting?
A.One. B.Two.
C.Three. D.Four
2.Which of the following statements is true?
A.Only people with bad handwriting are attracted to the medical field.
B.Most doctors’ handwriting gets better over the course of the day.
C.QD is shorthand for a Latin phrase meaning “three times as day”.
D.There is less chance for errors by using electronic medical records.
3.What’s the author’s attitude towards handwritten prescriptions?
A.Supportive. B.Disapproving.
C.Indifferent. D.Concerned.
4.What’s the best title for the passage?
A.No time left for doctors to write well.
B.Secrets that hospitals don’t want to tell you.
C.Reasons why most doctors have bad handwriting.
D.Errors reduced by using electronic medical records.

Imagine that a close friend ignores you when you arrive at his party. 1. But if you think about the situation differently, you would calm down. Using a particular emotion management strategy called reappraisal, which involves viewing an upsetting event in a positive light, is often effective in contributing to positive outcomes.
2. The research showed that if people believed feelings were malleable (可塑造的), they used reappraisal more frequently, and in return they had greater emotional health and life satisfaction.
University of Toronto researcher Brett Ford and her colleagues did another study. 3. The researchers found that the youths who believed emotions were controllable used reappraisal more and were less depressed than those who didn’t.
Does accepting our feelings impact our well-being? 4. In one research, the researchers stressed out participants by requiring them to give an impromptu (即兴的) talk. In another research, people kept daily diaries about how they handled stressors (紧张性刺激). In both cases participants who accepted their feelings experienced less negative emotions than people who judged their feelings.
“However, while emotions may be changed with efforts, that doesn’t mean they’re completely controllable,” says Eric Smith of Stanford University, “we shouldn’t expect to completely avoid or immediately remove certain of feelings. 5.”
A.It found a similar pattern.
B.You would be angry or upset, right?
C.We have beliefs about our emotions.
D.According to Ford and her colleagues, it does.
E.But we can learn to reduce them in hard times.
F.They were also less depressed and more satisfied with life.
G.Now, new research suggests our beliefs about our feelings affect us greatly.
