For thousands of years, people have told fables (寓言)     1     (teach) a lesson or to pass on wisdom. Fables were part of the oral tradition of many early cultures, and the well-known Aesop’s fables date to the     2     (six) century, B. C. Yet, the form of the fable still has values today,     3     Rachel Carson says in “A Fable for Tomorrow.”

Carson uses a simple, direct style common to fable. In fact, her style and tone (口吻) are seemingly directed at children. “There was once a town in the heart of America,     4     all life seemed to enjoy peaceful existence with its surroundings,” her fable begins,     5     (borrow) some familiar words from many age-old fables. Behind the simple style, however, is a serious message     6     (intend) for everyone.

    7     (difference) from traditional fables, Carson’s story ends with an accusation instead of a moral. She warns of the environmental dangers facing society, and she teaches that people must take responsibility     8     saving their environment.

The themes of traditional fables often deal with simple truths about everyday life. However, Carson’s theme is a more weighty     9     (warn) about environmental destruction. Carson proves that a simple literal form that has been passed down through the ages can still     10     (employ) today to draw attention to important truths.

Xiao long bao (soup dumplings), those amazing constructions of delicate dumpling wrappers, encasing hot,     1     (taste) soup and sweet, fresh meat, are far and away my favorite Chinese street food. The dumplings arrive steaming and dangerously hot. To eat one, you have to decide whether     2     (bite) a small hole in it first, releasing the stream and risking a spill (溢出),     3     to put the whole dumpling in your mouth, letting the hot soup explode on your tongue. Shanghai may be the     4     (recognize) home of the soup dumplings but food historians will actually point you to the neighboring canal town of Nanxiang as Xiao long Bao’s birthplace. There you will find them prepared differently — more dumpling and less soup, and the wrappers are pressed     5     hand rather than rolled. Nanxiang aside, the best Xiao long bao have a fine skin, allowing them     6     (lift) out of the steamer basket without tearing or spilling any of     7     (they) contents. The meat should be fresh with     8     touch of sweetness and the soup hot, clear and delicious.

No matter where I buy them, one steamer is     9     (rare) enough, yet two seems greedy, so I am always left     10     (want) more next time.

During China’s dynastic period, emperors planned the city of Beijing     1     arranged the residential areas according to social classes. The term “hutong”,     2     (original)meaning “water well” in Mongolian, appeared first during the Yuan Dynasty.

In the Ming Dynasty, the center was the Forbidden City,     3     (surround)in concentric(同心的)circles by the Inner City and Outer City. Citizens of higher social classes     4     (permit)to live closer to the center of the circles. The large siheyuan of these high-ranking officials and wealthy businessmen often     5     (feature)beautifully carved and painted roof beams and pillars(柱子). The hutongs they formed were orderly, lined by     6     (space)homes and walled gardens. Farther from the center lived the commoners and laborers. Their siheyuan were far smaller in scale and     7     (simple)in design and decoration, and the hutongs were narrower.

Hutongs represent an important cultural element of the city of Beijing. Thanks to Beijing’s long history     8     capital of China, almost every hutong has its stories, and some are even associated with historic     9     (event). In contrast to the court life and upper-class culture represented by the Forbidden City, the Summer Palace, and the Temple of Heaven, the hutongs reflect     10     culture of grassroots Beijingers.

Henry Tyler made the catch of the year on the weekend. When he saw a young child hanging from a sixth-floor apartment balcony (阳台), Henry ran one hundred metres, jumped over a 1.2-metre fence, and held out his arms to catch the     1     (fall) child.

Eric Brown, only three years old, knocked Henry down when he fell. The boy is in the hospital and doctors say he'll be OK.

    2     Brown family live in an apartment building outside Toronto. On the day of the accident, Mrs. Brown was at work and Eric was at home with his father. They both fell     3     (sleep) while watching TV.

Eric woke up a little later when he heard children playing outside. He pushed a chair onto the balcony, and climbed up     4     (see) them. When he looked down, he     5     (accidental) slipped and fell over the edge. He hung on for a few minutes     6     screamed for his father, but his father didn't hear him.

Henry     7     (fix) his car when he heard the screams. He looked up and saw Eric hanging from the balcony. He quickly     8     (throw) his tools aside, and started running, arms out.

"He saved my     9     (son) life," said Mrs. Brown. "I don't know     10     to thank him.”

"I just didn't want the boy to be hurt," said Henry.

Kim Cobb, a professor at the Georgia Institute of Technology in Atlanta, is one of a small but growing minority of academics     1     are cutting back on their air travel because of climate change. Travelling to conferences, lectures, workshops, and the like frequently by plane       2    （view） as important for scientists to get together and exchange information. But Cobb and others     3     （be） now questioning that idea pushing conferences to provide more chances to participate remotely, and     4    （change） their personal behavior to do their part in dealing with the climate change crisis. On a website called No Fly Climate Sci, for example,     5    （rough） 200 academics - many of them climate scientists     6     （promise） to fly as little as possible since the effort started two years ago.

Cobb, for her part, started to ask conference organizers who invited her to speak     7     she could do so remotely; about three-quarters of     8     time, they agreed. When the answer, was no, she, declined the     9     （invite）. That approach brought Cobb's air travel last year down by 75%, and she plans     10    （continue） the practice. "It has been fairly rewarding. ", she says, "a really positive change."

I've always loved the ocean. In the    1     (seven) grade,I started volunteering at the Monterey Bay Aquarium in California. I was upset to learn that many sea animals eat plastic garbage,     2     (think)it is food.

I decided to do something     3     (educate) people about this problem. I held presentations at schools to teach kids about plastic waste. I wanted to reach businesses too. I decided that if I learned of a company    4     used a lot of plastic, I'd send it an email urging it to cut back.

One day, I saw a commercial for a health-care company. People in the ad were using plastic straws （吸管）.   I found the contact information of the company    5     emailed its president. I told him how     6     (harm) plastic could be to the environment and asked him to consider using more eco-friendly options. I was so    7     (excite) when he wrote back to me.He said he would make sure that the company cut its use of plastic straws in half.

I kept going. Whenever I heard of businesses using plastic, I'd send an email. One of the biggest companies I wrote to     8     (be) Alaska Airlines Paris. A company     9     (represent) wrote back and told me the airline was switching over     10     plastic to paper cups on all of its 1,200 daily flights.
