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 shifting 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. And with all that leftover energy, these trees have started producing more seeds. This happens especially in places where white spruce (白云杉) grows.

White spruce, which is a North American tree, 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 eventually can 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 shelters for some snow. Keeping the sun's rays from making the white surface disappear. Instead, the trees absorb the sun's heat. This warms the surrounding air. The extra warmth encourages even more trees to produce seeds. That further boosts a forest's ability to expand. In addition, 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 impacts 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 shrinking of northern tundra.

B.The rising temperature.

C.The fierce and cold wind.

D.The abundant 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 surrounding air warmer.

D.New trees can bring more food and shelter to local animals.

4.The passage is most probably taken from ________.

A.a science report B.a health report

C.a fashion magazine D.a children's magazine

In her outstanding book, “Choose the Happiness Habit”, Pam Golden wrote, “Take the story of two twin brothers for example. One grew up and became an alcoholic (酒鬼), while the other became a successful businessman. When asked why he became an alcoholic, the alcoholic replied, “Because my father was a drunk.” However, the successful businessman’s answer was also “Because my father was a drunk.” when asked why he succeeded. The same background. The same upbringing (培养). However, the results were quite different. Why? The reason is that they had different choices. The brothers chose different thoughts which formed the situations they found themselves in at last, so they had different experiences.

There was a time in my life when I thought difficulty was due to “bad luck”. Have you ever heard the saying “When it rains, it pours”? That was my answer when others asked me how things were going on when I was in trouble. So what do you think I got? “RAIN”. More and more “RAIN”. I couldn’t understand why bad luck was always with me.

Pam Golden says, “You’re either living in the problem or you’re living in the solution.” Now, when I’m faced with what I used to think was a negative (消极的) situation, I use a different way to think about it. I force myself to replace those negative thoughts that make me lose heart in my mind with positive thoughts which encourage me to fight against the difficulty bravely. Sometimes I write down some ideas that may be a solution, which I combine with the lessons I have learned from the bad situations and the difficulties that troubled me in the past, and often, I find a solution to the problem soon. It seems that I should thank the difficulty I met with. The RAIN that poured in my world has become great experiences that provide me with valuable experience, from which I can benefit.

Now, it doesn’t “rain” as much in my life as it used to. In fact, most days are beautiful, cloudless and sunny! Sometimes I do get a rain, but I think it makes me stronger just like the rain helps plants grow up.
