Even if trees cannot walk, they are still on the move.
In parts of the Arctic, entire forests are moving northward. Across the Arctic, temperatures are rising faster than anywhere else in the world. As that happens, the tree line that marks where forests stop and the treeless tundra(冻原) starts has been moving northward. Trees growing along the tree line must protect themselves from the cold wind. To do this, plants tend to grow horizontal(水平的) branches low to the ground. The energy it takes for trees to grow this way means they don’t have enough energy to make seeds.
But as Earth’s climate has been warming, trees no longer have to just grow horizontally. Many can instead grow up toward the sky. This takes less energy. This happens especially in places where white spruce(白云杉) grows. White spruce, which is a North American trees, is quite able to produce a lot of seeds, which can move long distances in the wind. When wind-blown seeds end up on the tundra beyond the tree line, they finally sprout(发芽) new trees. This explains how a forest can move. Of course, the process would work only if the tundra were warm enough. But in recent years, the whole planet has been warming.
New trees will provide shelter for some snow. Keeping the sun’s rays from making the white surface disappear. Instead, the trees absorb(吸收) the sun’s heat. This warms the air around. The extra warmth encourages even more trees to produce seeds. That further increases a forest’s ability to expand(扩展). What’s more, more trees will trap more snow, preventing much of it from being blown away. Snow can trap heat in the soil below, which encourages trees to grow. The recent rise of temperatures has helped more trees grow past the tree line. People worry about effects on the animals that depend on frozen conditions for food and shelter.
1.What is the main cause of the trees in the Arctic moving northward?
A. The reducing of northern tundra.
B. The rising temperature.
C. The cold and strong wind.
D. The rich resources in the north.
2.What does the underlined word “this” in Paragraph 2 mean?
A. To produce more seeds.
B. To move northward.
C. To respond to the climate change.
D. To protect themselves from the cold wind.
3. What can be inferred from the last paragraph?
A. New trees can trap the snow, which may make the soil colder.
B. The trapped snow prevents new trees from producing more seeds.
C. New trees can make the air around warmer.
D. New trees can bring more food and shelter to local animals.
Parties and social gathering no longer excite us the same way they once did. This is not because of a lack of desire to socialize, but the mobile-phone.
At parties, more people are on their phones than on their drinks. According to a recent International Data Corporation Study, over half of all Americans have a smartphone and reach for it as soon as they wake up, keeping it in hand all day. In addition, too many people in society are using smartphones while driving and as a result, they get into car crashes. 34 percent of teenagers admit sending messages while driving, and they agree that sending messages is their number one driving interruption. People’s addiction(沉溺) to their smartphones is unbelievably becoming more important than the lives of themselves and others.
Just as drivers ignore the importance of focusing while on the road, many people also fail to recognize the importance of human communication. When with their friends, some people aimlessly check or send messages in front of a friend, which sends a message to that friend: the person I am texting is more important than you. In addition, relying on our smartphones to make friends does not give us the same advantage as being able to make new friendships in the real world. Face-to-face conversations will give us much stronger communication skills in the long run.
As many people risk their lives and the lives of people around them just to send a message or mindlessly check their messages, smartphones are in many ways more dangerous to people. The quality of this technology is preventing societal achievements and weakening the value of communication. Not only is the smartphone affecting our desire to communicate face to face, but it is also lowering society’s ability to communicate.

I am a taxi driver. One Monday morning, I had stopped at New York Hospital when I found a well-dressed man dashing down the steps. He was waving to me. I waited until he jumped into the cab. “ LaGuardia Airport, please,” he said.
As always, I wondered about my passenger. “ What do you do?” “ I am in the neurology department(神经内科) at the hospital.” For some unknown reason, I decided to ask for his help.
“ Could I ask a favor of you?” He didn’t answer. “ I have a son, 16. He’s doing well in school. He wants a job this summer. Is there any possibility that you might get him a summer job?” After a pause, he said, “ The medical students have a research project. Maybe he could fit in. Have him send me his school records.” He searched his pocket and handed me a card.
That evening, I pulled the card from my pocket. “ Robbie,” I announced proudly, “ this could be a summer job for you. Send him your school records.” He read it out loud, “ Fred Plum, New York Hospital.” “ Is this a joke?” he said in disbelief. After I shouted and threatened(恐吓) to cut off his pocket-money, Robbie promised to send off his grades the next morning.
Two weeks later, when I arrived home, my son handed me a letter from Plum. He was to phone Plum’s secretary for an interview.
Robbie got the job. The white coat he wore made him feel more important than he really was. As high school graduation neared, Plum was kind enough to write letters of recommendation(推荐) for universities. To our delight, Robbie was admitted to New York Medical College.
It never occurred to me that a stranger should change my son’s future.

Cities, whether big and small, should be clean. Only when we live in a clean city we live a happy life. As we know, a clean city, that disease may be reduced and people’s health may be better, are good both to our mind and body.
