【题目】

When a leafy plant is under attack, it doesn’t sit quietly. Back in 1983, two scientists, Jack Schultz and Ian Baldwin, reported that young maple trees getting bitten by insects send out a special smell that neighboring plants can get. These chemicals come from the injured parts of the plant and seem to be a warning. What the plants pump through the air is a mixture of chemicals known as volatile organic compoundsVOCs.

Scientists have found that all kinds of plants give out VOCs when being attacked. It’s a plant’s way of crying out. But is anyone listening? Obviously. Because we can watch the neighbors’ react.

Some plants pump out smelly chemicals to keep insects away. But others do double duty. They pump out perfumes to attract different insects who are their natural enemies. Once the insects arrive, the tables are turned. The attacker who was lunching now becomes lunch.

In study after study, it appears that these chemical conversations help the neighbors. The damage is usually more serious on the first plant, but the neighbors stay safer because they heard the warning and knew what to do.

Does this mean that plants talk to each other? Scientists don’t know. Maybe the first plant just made a cry of pain or was sending a message to its own branches, and so, in fact, was talking to itself. Perhaps the neighbors just happened to hear the cry by accident and so wrong information was exchanged.

Charles Darwin, over 150 years ago, imagined a world far busier, noisier and more intimate than the world we can see and hear, our senses are weak. There’s a whole lot going on.

【题目】

The Spring Festival in 2020, the year of rat is quite unusual because of the disease caused by the novel coronavirus (新型冠状病毒) which has already spread in many provinces especially in Hubei province. People feel worried because many people caught the pneumonia(肺炎).

The government announced that 2,744 confirmed(确认的) cases of pneumonia caused by the virus, including 461 in serious conditions, had been reported in the country by the end of SundayJan 26th2020.

The whole country is taking action to prevent the spreading of the disease. People stay at home instead of going to public places or visiting their relatives. The streets in most cities are almost empty. People wear masks when they go out. Many provinces sent medical teams to Wuhan to help control the situation.

【题目】Should I Be Allowed to Make My Own Decisions?

Many teenagers have hobbies. But sometimes these hobbies can get in the way of their schoolwork, and parents might worry about their success at school. Teenagers often think they should be allowed to practice their hobbies as much as they want. Do you agree?

Liu Yu, a fifteen-year-old boy from Shandong, is a running star. He is on his school team and has always wanted to be a professional runner when he grows up. However, his parents won't allow him to train so much. "Of course we want to see him achieve his dreams," says Mr. Liu. "And we know how much he loves running. My wife and I have supported every one of his races. We have nothing against running. But we think our son needs to think about other possible jobs. He's getting older now, so he needs to think about what will happen if he doesn't end up as a professional runner."

Liu Yu doesn't really agree. "Well, I think I should be allowed to decide for myself," he says. "My parents have always taught me how important it is to work hard at school and enter university. I understand this, but I'm serious about running. It's the only thing I've ever wanted to do."

His parents believe that Liu Yu should study hard in the evenings so they don't allow him to practice running at night. "Maybe he thinks it's too strict or unfair," says Mrs. Liu, "But we think we're doing the right thing. He needs to spend more time on his homework because it is difficult to become a professional sports star."

But Liu Yu still disagrees. "I know my parents care about me. They always talk about what will happen if I don't succeed. But I will! I'm a quick runner! I think I should be allowed to make this choice myself. Only then will I have a chance to achieve my dream."
