Read the article and select the best answer. Article: Sweet peas, cucumbers, grapes ---- what do you think they have in common? None of these vegetables grow on trees. They all don't have strong roots, big trunks or long branches, which makes it harder for them to get sunlight. But don't worry. They have developed their own unique way of growing taller climbing! Take sweet peas as an example. The plant grows as a straight stem until it finds something to hold onto, either a nearby tree or a stick. That is when the stem makes small coil that helps the plant hold the stick tightly. How these plants are able to do this has been a mystery to scientists for years. Even Charles Darwin was interested in this question. But it is not until now that a Harvard research team has finally found the answer. The study was published in the Journal Science earlier this month. The key, as it turns out, is inside a kind of thread-like cell called "g-fiber cell", which has the ability to shrink or stretch. Each stem of the pea plant is made of several layers of g-fibers. Once the plant finds something to hold onto, cells on side of the stem start to shrink, forcing the whole thing to bend and coil, which is a bit like how our muscles get our bodies to move. What's more, a pea's coil is not exactly like that of a spring. If you look closely, you may find that a spring coils all in the same direction, but a plant's coil is in two opposite directions, like a telephone line. This means that the stem can stay soft when pulled gently but become strong enough when pulled harder. "You want the plant to have a little bit of flexibility so that if the wind blows or an animal disturb it, it doesn't break," explained Sharon Gerbode, author of the study. "This structure allows the plant to easily accommodate small movement, but then if something really serious happens it can become strong and protect itself." Question: What's the purpose of the writer in the passage? Options: A: To tell us why the sweet peas can climb the tree or stick. B: To display new research allows scientists to understand more about climbing plants. C: To show us new scientific research about the role of "g-fiber cell". D: To tell us the mysterious natural phenomena of some plants.

Article: There are many types of reports.A report is simply an account of something that has happened.The commonest are news reports.We get them in newspapers,over radio and on television.Sometimes cinemas also show us newsreels.

Ques: Read the article and select the best answer. Article: Well, what a bonus! Lots of us are using technology to find rides, and not just to school. It's awkward to call a friend and ask for a ride, and half the time they'll say, "Sorry,my car is full." But with Twitter and Facebook, you just tweet Ashleys Pool Party and look for other people heading the same way. It may sound risky, but many teens stay within their own social circles to find rides, and don't branch out beyond friends of friends when asking on Twitter. For me, I only rideshare with people I know, but to some young people, especially those taking longer trips, stranger danger is less of a concern. The sharing economy got big during the recession . It allows people to access more goods and services using technology, while also allowing them to share cost. And that, technology, for me, is what the car was for my mom, a gateway to more freedom. According to the researchers at the University of Michigan,30 years ago, eight in ten American 18-year-olds had a driver's license. Today it's six in ten. So it's not that surprising that on my 16th birthday I wasn't rushing to get a license. All I wanted was an IPhone, Juliet Schor (Sociology professor at Boston College) knows people of my age love being connected and for young people driving means they have to disconnect from their technology, and that's negative. So if they could sit in the passenger side and still be connected, that's going to be a plus. To me, another plus is ridesharing represents something much bigger than trying to save money. I see it as evidence that people still depend on each other. My generation shares their cars and apartments the way neighbors used to share cups of sugar. For the system to work, we still need our own cars. But until I get my own version of the silver Super Beetle, you can find me on twitter. Question: Driving has become less of a choice for young people because _ . Options: A: they have to try hard to get a license B: it makes their connecting using technology impossible C: driving one's own cars creates a negative impression D: driving means offering free rides to others
Ans: B

Read the article and select the best answer. Article: Looking almost as fresh as the day it was bought, this McDonald's Happy Meal is in fact a staggering six months old. Photographed every day for the past half a year by Manhattan artist Sally Davies, the kids meal of fries and burger shows no sign of mould or decomposition . In a work named The Happy Meal Project, Mrs. Davies, 54, tries to provide evidences that McDonald's food really is the worst you can put in your body. Sitting on a shelf in her apartment, Sally has watched the Happy Meal with increasing shock and even her dogs have resisted the urge to try and steal a free tasty snack. "I bought the meal on April 10 of this year and brought it home with the intention of leaving it out to see how it changed," she said. "I chose McDonald's because it was nearest to my house. The first thing that struck me on day two of the experiment was that it no longer gave out any smell. And then the second point of note was that on the second day, my dogs stopped circling the shelf it was sitting on trying to see what was up there." Expecting the food to begin moulding after a few days, Mrs Davies' surprise turned to shock as the fries and burger still had not shown any signs of decomposition after two weeks. "It was then that I realised that something strange might be going on with this food that I had bought," she explained. "The overall appearance of the food did not change as the weeks turned to months. And now, at six months old, the food is plastic to the touch. The only change that I can see is that it has become hard as a rock." As a strict vegetarian, Mrs. Davies' experiment has brought her amusement rather than fear. "Maybe I would be frightened at seeing this if I was a meat eater. Why hasn't even the bread become with mould? It is strange. Question: We know from the passage that Sally Davies _ . Options: A: keeps the record of the food by smelling it B: manages The Happy Meal Project in Boston C: is a Manhattan artist who likes meat very much D: doubts if McDonald's food meets health standards
