【题目】阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。
No one would much like the idea of eating 61 pounds of tomatoes a day. But if their goodness was put into an easytoswallow pill that you were told might prevent strokes(中风) and heart attacks you would probably be putting in an order tomorrow.
Researchers believe they may have come up with just that after trials. The daily pill contains a chemical called lycopene which makes tomatoes red and is known to break down fat in the vessels(血管).A Cambridge University study found taking the pills improved blood flow and the lining of vessels in patients with preexisting heart conditions. It also increased the flexibility(灵活性) of their vessels by 50 percent. The scientists believe it could limit the damage caused by heart disease—responsible for 180,000 deaths a year—and help cut the 49,000 deaths a year from strokes. They also hope it could benefit those with arthritis(关节炎), diabetes(糖尿病) and even slow the progress of cancer.
Each pill is equal to eating around 61 pounds of ripe tomatoes. Studies have shown eating a Mediterraneanstyle diet rich in tomatoes, fish, vegetables, nuts and olive oil can significantly reduce cholesterol(胆固醇) and help prevent cardiovascular disease.
Preliminary results from a twomonth trial, in which the pill was given to 36 heart disease patients and 36 healthy volunteers with an average age of 67, were presented at a meeting of the American Heart Association. It was shown to improve the function of the endothelium—the layer of cells lining blood vessels. It also improved their sensitivity to nitric oxide, the/span> gas which causes the enlargement of the vessels in response to exercise.
Ian Wilkinson, head of Cambridge University's clinical trials unit, said,“These results are potentially very significant and it meets the goal, but we need more trials to see if they translate into fewer heart attacks and strokes.”
Further studies are planned, with researchers hoping it could offer a choice for heart disease sufferers who can not take the cholesterollowing drugs.
Mike Knapton, head of the British Heart Foundation, said, “Although this showed lycopene improved blood flow in people with heart disease, that's a long way from demonstrating that taking it could improve outcomes for people with heart disease. The best way to get the benefits of a good diet is to eat plenty of fresh fruit and vegetables.”

【题目】阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。
Scientists recently found three animal species living two miles below the surface of the Mediterranean Sea, where the super-salty waters don’t have oxygen(氧). They’re multicellular(多细胞的), which means their bodies have many cells. They each are as small as a large grain of sand. But they are animals.
The most exciting thing about these creatures, say the scientists, is that they obviously don’t need oxygen to live. What biologists know about life so far is that only single-celled living things can live in places that have no oxygen, and that multicellular organisms(有机物) can visit these places, but not live there. These newly found creatures could change that idea.
Finding animals down there was so surprising that the scientists couldn’t believe it. At first, “we thought they were dead bodies,” Roberto Danovaro, a scientist at the Polytechnic University of Marche in Ancona, Italy, told Science News. To find out whether the animals could actually live there Danovaro and his colleagues brought up more samples(样本) from the ocean floor. Studying the animals in the new samples showed that they appeared to be alive.
The researchers did more tests, and found that some of the animals had eggs—which suggests they were reproducing(繁殖). Also in the samples were old skins, suggesting that the animals had lived there long enough to grow. Finally, pictures taken showed that the insides of the animals appear to be adapted to live in an environment that has no oxygen.
These clues suggest the animals don’t need oxygen, but the evidence(证据) is indirect, which means that scientists still have not observed how the animals live without oxygen. This means more studies are needed, but the scientists think they’re on the right track. And if they’re right, biologists will need to rethink what they know about where animals live.
【1】What excited the scientists most is that ______.
A.they found three animal species visit the salty water under the Mediterranean Sea
B.single-celled animals can live in super-salty waters
C.the tiny animals have many cells
D.three kinds of animals can live in places that have no oxygen
【2】The underlined phrase in Paragraph 2 means the scientists could think _____.
A.only single-celled creatures don’t need oxygen to live
B.multicellular animals can visit the super-salty waters
C.the newly found creatures can’t live in the super-salty waters
D.multicellular animals also can live without oxygen besides single-celled ones
【3】Which of the following CAN’T be used to prove the newly found creatures can live in super-salty waters?
A.Their dead bodies are found there.
B.Some in the samples have eggs.
C.Some old skins are found in the samples.
D.The pictures of their insides have been taken.
【4】More studies are needed to prove_____.
A.where single-celled animals can live
B.how the newly found animals live without oxygen
C.whether the multicellular creatures can live underwater
D.why the super-salty waters have no oxygen

【题目】阅读理解。
While astronauts in space get to do many exciting things, they miss out on ordinary things that we all take for granted—being able to walk on firm ground, hanging out with family and digging into a slice of hot steaming pizza. Though not much can be done about the first two things, there may soon be a solution to the third one, thanks to this cool 3D pizza printer!
About a year ago, NASA offered $125,000 to Anjan Contractor, a 3D technology expert,to build a device(设备) that would allow astronauts to make pizza on demand. The mechanical engineer promised that his invention would produce pies in large quantities that looked, tasted and even smelled like pizza made in common ovens.
Late last year, the engineer presented a video of his first prototype(原型) that begins by creating a single slice of dough(面团) that is cooked and printed at the same time. Then comes the tomato “sauce”—a mix of tomato powder, oil and water and finally, a protein slice that resembles cheese. While the video doesn't show the baking process, the inventor says that once the pizza is printed, it can be ready to be consumed in 7 seconds.
While the pie in the video looks delicious enough to attract any pizza lover, Anjan Contractor is far from ready for astronauts. That's because he still has to find a solution to make the food container in the printer last for 30 years. Though that may sound unrealistic, actually it is not.
Anjan Contractor believes that the only way thatis possible is that the water is removed from all the ingredients (配料) and then they are reduced to the powder form. This, as you can imagine, will not be so easy.But, while the printer may not be ready for space, it certainly looks ready enough for people on earth.Hopefully, NASA and Contractor will consider selling it to those not fortunate enough to go to Mars!
【1】Why does the author mention the things that astronauts in space cannot do?
A.To ask us not to take common things for granted.
B.To show they live a difficult life there.
C.To show their life is boring in space.
D.To introduce the topic of the text.
【2】NASA offered $125,000 to Anjan Contractor mainly to ________.
A.create some new type of 3D printer
B.attract more companies to work for NASA
C.help astronauts in space enjoy fresh pizza one day
D.produce pizza in large quantities to earn great profits
【3】The biggest challenge that Anjan Contractor is faced with now is probably that ________.
A.he has no money left to go on with his research
B.the pizza doesn't seem appetizing to pizza lovers
C.he has no way to make pizza that can last forthirty years
D.he cannot make the food container last for decades
【4】What's the best title of the passage?
A.NASA is trying its best to help astronauts eat better
B.Astronauts may soon be able to enjoy steaming hot pizza
C.NASA is working on making pizza for common people
D.A 3D pizza printer has been used to make pizza

【题目】Chokwe Selassie, aged 13, is working hard to help drivers avoid potholes(坑洼). The eighth-grader was inspired to kick off his creation on a recent morning, when his mother was driving him to school. Their car was damaged as it went over a huge pothole in the middle of the street in their hometown of Jackson, Mississippi. He decided to do something about the pothole problem in his city. His solution: an app that warns drivers when there is a pothole ahead.
Chokwe developed the app with his friends Rodriguez Ratliff and Emmanuel Brooks. When the app detects a pothole, it is highlighted in red. And if you get close to the pothole, your phone will warn you. Drivers can also use the app to report any potholes they meet, and to look for other routes they can take to avoid roads that have them.
The app relies on current available information about the streets of Jackson. It works by using the city’s 311 call system, and uses information already stored in a database. Through the call system, citizens dial 311 to report non-emergency problems, which include potholes. Chokwe and his friends determined that focusing on the 10 busiest streets in Jackson would give them a large enough sample size to test the prototype(原型).
Although the app isn't yet available for sale, Chokwe is already looking for ways to improve it. The prototype remains limited to 10 streets in Jackson, but he hopes to add more, so that it includes every street in the city. And then he wants to go even farther until it's nationwide.
【1】The passage is mainly about ________.
A. a solution to traffic jams B. an App to detect potholes
C. pothole problems in big cities D. poor road conditions
【2】What’s the closest meaning of the underlined phrase “kick off” in Paragraph 1?
A. leave B. invent
C. begin D. change
【3】How does the app work through the 311 call system?
A. By replying to citizens’ calls.
B. By broadcasting traffic accidents.
C. By settling non-emergency problems.
D. By using its information about potholes.
【4】Which can be Chokwe’s future target?
A. Encouraging more kids to create apps.
B. Taking part in more learning programs.
C. Making the app available for sale online.
D. Making the app include streets nationwide.
