短文大意：短文以龐大的數(shù)字揭示了一些令人驚愕的事實(shí)，以幫助人們更多地了解人體和環(huán)境保護(hù)。

【1】題意：將段落A~F與兩個(gè)主題匹配：①人與環(huán)境；②人體。以下哪一項(xiàng)是正確的？考查主旨?xì)w納。根據(jù)A:If we laid all of the blood vessels in the human body end to end; C:If your throat tickles, pressing your ear might make it go away; E: According to the US scientists, young people’s brains deal with information faster than older people. 和F: About 200 muscles work together when you take a step.可知the blood vessels（血管）/ throat（喉嚨）/ear（耳朵）/brains（大腦）和muscles（肌肉）都是人體器官，與主題②The Human Body相符；根據(jù)B: For the first time, Coca-Cola has showed that it uses 3,000,000 tons of plastic bottles each year. 和D: It takes about 7 to 8 trees to make enough O2 for one person to breathe for a year.可知兩個(gè)段落介紹的是人們所處的外部環(huán)境，符合①People & Surroundings主題。綜合以上分析，故選C。

【2】題意：所有六個(gè)段落最好的標(biāo)題是什么?考查標(biāo)題歸納。A. 奇怪的世界；B. 驚人的事實(shí)；C. 難以置信的數(shù)字。根據(jù)六個(gè)段落的內(nèi)容可知，每個(gè)龐大的數(shù)字都與一個(gè)驚人的事實(shí)相聯(lián)系，例如A段If we laid all of the blood vessels in the human body end to end, they would reach about 100,000km long.

【5】題意：下面哪個(gè)選項(xiàng)得出“30,000”這個(gè)數(shù)字?考查細(xì)節(jié)計(jì)算。A. 通過走150步，一起運(yùn)動(dòng)的肌肉量。根據(jù)About 200 muscles work together when you take a step.可知200×150＝30，000。B. 三個(gè)人體中連接在一起的血管的長(zhǎng)度。根據(jù)If we laid all of the blood vessels in the human body end to end, they would reach about 100,000km long.可知100000×3＝300，000。C. 40人一年呼吸氧氣的重量。根據(jù)D段Each person needs around 750kg of O2 per year.可知750×40＝30,000。綜合以上計(jì)算，故選C。

【題目】 Still in shock! I moved around the house purposelessly trying to decide what to put into the suitcases (行李箱). Earlier that evening, I’d received a call telling me that my brother was killed in a car crash. “Come as soon as you can.” cried my mother.

I wanted to hurry to her at once. But my husband, Larry, and I were packing to move from New York to Seattle. Our house was in total mess. Supper dishes sat on the kitchen table. Toys lay everywhere. I purposelessly picked things up and put them down. Mother’s crying went through my head again and again.

Larry called some friends to tell them what had happened. Someone asked to speak to me. “If there’s anything I can do, let me know.” But I didn’t know what to ask for.

Suddenly, the doorbell rang. It was Emerson. He and his wife Donna lived in the block nearby.

“I’ve come to clean your shoes,” he said.

I asked him to repeat.

“Donna had to stay with the baby,” he said, “but we want to help you. I remember when my father died, it took me hours to clean our shoes for the funeral (葬禮). Give me all your shoes.”

I gathered all our dirty shoes to the kitchen. Emerson got to work right away. Watching him devoting himself to one task helped me pull my own thoughts into order. I told myself to wash clothes first. Then, Larry and I bathed the children and put them to bed. One job after another.

When we returned to clear the dishes, Emerson had left. All our shoes stood in a line against the wall, clean, shining. I couldn’t help crying. Early next morning, we left for the airport with all the jobs done.

Now whenever I hear of a friend who’s lost a loved one, I no longer call with the polite offer,” If there’s anything I can do …” Instead I try to think of one specific task that suits that man’s need, like taking the dog to the boarding kennel, or house-sitting during the funeral. If the person asks,” How did you know I needed that one?” I reply, “Because a man once cleaned my shoes.”

【4】If one of her friends has lost a loved one, what will the writer probably NOT do?

A. Call her friend to ask what she can do.

B. Look after her friend’s young children.

C. Take her friend’s dog to the boarding kennel.

D. Offer her friend house-sitting during the funeral.

Global warming is a big problem that we have to stop. One of the best things we do is to plant more trees. Trees can take in CO2 in the air and stop global warming. 【1】

A team of scientists at Boston University has been working with NASA to study Earth’s green vegetation (植被). They used a special NASA camera and found that global leaf area had increased by 5 percent since the early 2000s. 【2】 That’s about one-quarter of the size of the entire Amazon rainforest.

The growth mainly came from China’s forest protection programs, NASA said. For example, since 1962, China has been planting trees in Saihanba, Hebei Province. It was once a desert. 【3】 Ant Forest, a feature in Alipay app, gives users points for doing eco-friendly things such as walking and going paperless in the office.
