It’s never a real problem for us when the weather gets cold. We can put on more clothes, stay next to a fireplace, turn on the air conditioner or simply travel to a warmer city to spend the winter – people have many different ways of dealing with the cold.
　　 But things are not as easy for plants. Unlike humans, plants can’t move to escape the cold or generate heat ( 发热) to keep themselves warm. So how do they manage to survive the freezing winter?
　　 It turns out that plants have their own strategies （策略） too, said a study published on Dec 22 in the journal Nature.
　　 According to researcher Amy Zanne of George Washington University, US, the cold is a big challenge for plants. Their living tissues （活组织） can be damaged when they freeze. “It’s like a plant’s equivalent to frostbite ( 相当于冻疮),” Zanne told Science Daily. Also, the process of freezing and thawing　 (解冻) can cause air bubbles （气泡） to form in the plant’s water transport system. “If enough of these air bubbles come together as water thaws they can block the flow of water from the roots to the leaves and kill the plant,” she explained.
　　 To live through cold weather, plants have developed three traits （特性） , according to the study. Some plants, such as oak trees（橡树）, avoid freezing damage by dropping their leaves before the winter chill sets in – effectively shutting off the flow of water between roots and leaves – and growing new leaves and water transport cells when the warm spring returns.
　　 Other plants, pine trees（松树） for example, protect themselves by narrowing their water transport cells, which makes it easier for cells to travel among air bubbles.
　　 The third strategy is also the most extreme – some plants die on the ground in winter and start growing as new plants from seeds when conditions get warmer.
　　 However, the study also found that these smart strategies were developed very slowly – over millions

of years of evolution （ 进化）. This leads scientists to worry that plants may not be able to deal with human-caused climate change, which has only started occurring over the past few decades.
　　 Scientists are hoping that this study can help people find possible ways to save plants from the threat

of climate change.

A. Why plants are not afraid of the winter chill.

B. The ways that plants survive cold weather.
C. Changes in plants’ water transport system in winter.

A. it produces more living tissues to stay alive
B. its leaves quickly fall out and its roots begin to die
C. lots of air bubbles form in its water transport system
D. its water transport system could be blocked in the spring

3.What are scientists worried about when it comes to plants according to the article?
A. Plants may not be able to adapt to the increasingly cold climate.
B. Human activities might have a great impact on the pace of plants’ evolution.
C. Plants may not be able to evolve fast enough to adapt to human-caused climate change.

The Internet plays a big part in human life. We use it for work and entertainment. We can find new recipes on the Interact or advice on staying healthy. We can even use it to learn a new language. We use the Internet to keep in contact with family and friends and stay in touch with issues we care about. The list goes on and on.

Well, there may be no going back to an Internet-free life. But can using the Internet too much be bad for our health? It might be, say researchers. A new study finds that heavy Internet use may be connected to high blood pressure in an unlikely group---teenagers. So, try to be a responsible guardian for your children.

The study results show that teens who spend at least 14 hours a week online are more likely to have high blood pressure. High blood pressure makes your heart and blood vessels work too hard. Over time, this extra strain increases your risk of a heart attack or stroke. High blood pressure can also cause heart, kidney and brain diseases.

The Henry Ford Hospital in Detroit, Michigan did the study. It involved 335 young people, from 14 to 17 years old. One hundred and thirty-four of the teens were described as “heavy Internet users”. Researchers found that out of these 134 teens, 26 had high blood pressure. The researchers say the study is the first one to connect heavy web use with high blood pressure. Another research has connected that heavy Internet use with health problems including anxiety, depression and obesity.

The lead researcher of the study is Andrea Cassidy-Bushrow. For the purpose of the study, she explains, teens considered heavy Internet users were online on average “25 hours a week”. In a statement she said, “Using the Internet is part of our daily but it shouldn’t consume us.”

Ms. Gassidy-Bushrow adds that it is important for teens to take regular breaks from their computers or smart phones and to do some kinds of physical activities. She also suggests that parents limit their children’s use of the Internet to two hours a day, five days a week.

1.The author mainly wants to tell us 　　　　 .

A. how to prevent high blood pressure.

B. too much Internet use may be bad for teenagers.

3.According to Casssidy-Bushrow, teenagers’ use of the Internet should be limited to 　　　　 .

A. 25 hours a week　　 B. fourteen hours a week
