The Vine That Ate the South

    Kudzu is a fast-growing vine(蔓生植物) that covers a large area in the southern United States. It is so common that one might think it is a native plant, but it is not. Kudzu was brought to the United States from Japan in 1876. Many Americans thought it was beautiful, and they began to plant it. They didn't know it could grow up to a foot a day during the summer months. Nor did they know it would grow up and over anything in its path.

    In Japan, kudzu experienced cold winters and a short growing season. But in the United States, it has a very long growing season with warm and wet southern weather. It is fine weather for the vine to grow fast.

    In the 1920s, people used the vine to feed farm animals. Ten years later, the government supported to plant kudzu because it kept soil from washing away. However, by the 1950s, the government no longer wanted people to plant the vine. Twenty years after that, the government said it was a harmful plant.

    The vine grows up trees and buildings, making some beautiful shapes. However, trees die after kudzu covers them because they cannot get enough light. Scientists are looking for ways to kill the vine. They used poisons(毒药) to kill the vine. However, some of the poisons made it grow even better. Scientists also find it difficult to dig up Kudzu. The plant is really tough.

    Because kudzu is so hard to kill, some people are making the best of it. So they try to find different uses for the vine. They find the vine can be used to make paper and baskets, it can be used to feed the goats, and it can even be eaten by people. Scientists are studying it in the hope that the vine can be used as a medicine. At the very least, kudzu serves as an example of the unexpected results that can come from non-native plants.

(1)、We can learn from the passage that ________.
A、kudzu mostly grows in the northern America B、kudzu was brought to Japan from America C、kudzu grows very fast in warm and wet weather D、American government has never supported to plant kudzu
(2)、The underlined word "tough" in Paragraph 4 probably means "________".
A、not easily broken B、widely used C、hard to grow D、important to one's health
(3)、The last paragraph is mostly about ________.
A、how quickly the vine grows B、how people use the vine C、why people want to kill the vine D、why people eat the vine
(4)、The writer uses the title "The Vine That Ate the South" most probably to ________.
A、let readers know kudzu is a vine B、interest readers in a humorous way C、tell readers the vine is a kind of food D、get readers to realize the passage is serious

Say you're sitting around with some friends playing video games and someone mentions a game that happens to be one of your favorites. "Oh, that game's easy. So not worth the time, " one of your friends says. The others agree. Although you enjoy the game quite a lot, not wanting to argue with them, you go along with the crowd.

You have just experienced what is commonly referred to as peer pressure, also called peer influence. You will adopt a certain type of behavior, dress, or attitude in order to be accepted as part of a group of your "peers". As a teen, you are likely to have experienced the effect of peer pressure in a number of different areas.

We are all influenced by our peers at any age. For teens, as school and other activities take you away from home, you may spend more time with your friends than with your family. As you become more independent, your peers naturally play a greater role in your life.

According to Dr. Casey from Cornel University, teens are very quick and accurate in making decisions on their own and in situations where they have time to think. However, when they make decisions in the heat of the moment or in social situations, their decisions are often influenced by factors like peers. In a recent study, teen volunteers played a video driving game, either alone or with friends watching. The researchers discovered that the number of risks teens took more than doubled when their friends were watching, compared with when they played alone. This shows that teens may find it more difficult to control risky behavior when their friends are around, or in situations where they are extremely angry.

Just as people can influence us to make unwise choices, they can also influence us to make good ones. A teen might join in a volunteer project because his or her friends are doing it, or get good grades because his or her friends think getting good grades is important. In fact, friends often encourage each other to study, or try out for sports.

While we are always influenced by those around us, the decision to act or not is up to us. So when it comes to decision making, the choice is up to you.

 阅读下面短文,从每题所给的A、B、C、D四个选项中选出最佳选项。

①It is widely known that China has the best high-speed railway network (网络) in the world. Now, the country is breaking its own speed(速度) record with CR450. 

②CR450 can travel at 400 kilometers per hour on average, with a top speed hitting 453km/h. Before this, the fastest high-speed train operating in a rail network in the world is China's CR400, which runs at 350 km/h on average. Once put into use, for example, the CR450 will shorten the travel time from Beijing to Shanghai to just about two and a half hours, which takes at least four and a half hours at the moment. 

③"The key is not to make the train run fast but to have it brake (刹车) accurately (精准地) and steadily (平稳地), " Zhao Hongwei of the China Academy of Railway Sciences told CCTV News. The standard is that the CR450 should have the same brake distance as the CR400, which is 6, 500 meters, even though it travels a lot faster. It can also start braking more quickly, taking just 1. 7 seconds compared to the 2. 3 seconds needed for the CR400. 

④The engineers did lots of tests with the brakes to make the system better. In the tests, the brake disc (制动盘) got really hot, reaching temperatures of up to 700℃. Its color changed from black to red. The changes were then recorded. All the data were saved in a smart system to make a digital model of the brake system for calculations (计算). 

⑤Besides having a better braking system, the CR450 has the same noise level as the CR400. Moreover, it is 12 percent lighter and 20 percent less energy-consuming (耗能的), according to CCTV News. With all its advantages, people are getting excited about the train's debut (首次亮相), which is planned to be within this year.
