Jane Goodall was born in London in 1934. She became interested in animal stories when she was a very young child. She always dreamed of working with wild     1     (animal).   When she was eleven years old, she decided that she wanted     2     (go) to Africa to live with and write about animals. But this was not the kind of thing young women usually did in the 1940s. Everybody was laughing except her mother. “If you     3     (real) want something, you work hard, you take advantage of the opportunity, you never give up,and you will find a way,” her mother said to her. The opportunity     4     (come) at last. A school friend invited her to Africa. Jane worked as     5     waitress until she got enough money to travel there.

In 1957, Jane Goodall traveled to Africa. She soon met the well-known scientist Louis Leakey and began working for him as an assistant. He later asked her to study a group of chimpanzees     6     (live) by a lake in Tanzania. Very little was known about wild chimpanzees at that time.

Jane spent many years studying chimpanzees     7     this area of Africa. It was no easy work. They were very shy     8     would run away when she came near. She learned to watch them from far away using binoculars (双筒望远镜). Over time, she slowly gained     9     (they) trust. Watching the chimpanzees, she made many discoveries. They ate vegetables and fruit. But she found that they also ate meat. A few weeks later, she made an even more     10     (surprise) discovery. She saw chimpanzees making and using tools to help them catch insects.

Bird-watching has been included in a public benefit program “Park Classes” in Wuhan schools.     1    (bury) in books and having little access to the outside world, many students don’t have the     2    (little) idea of what nature really is.

This program is designed     3    (raise) the awareness of environmental protection among school kids,     4     often feel greatly refreshed by appreciating the grace of the adorable creatures through cameras.

Among the selective courses     5    (be) the restoration of small and micro wetlands. As for this course, what     6    (need) is a lot of hands-on practice. Under the     7    (guide) of their teachers, students are required to conduct research on a 500-square-meter wetland in the city parks. Focusing their attention     8     the wetland’s physical condition, they have recorded the number of plant and animal species to create a restoration plan. Thanks to their efforts, the biodiversity of the wetland has been     9    (significant) improved.

“It’s very meaningful,” said Li Chenliang,     10     eighth grader from this project. “I have gained a lot of knowledge that cannot be directly got from books. I should make full use of the city’s ecological advantages and get more chances to get closer to nature.”

Most rainforests lie close to the equator (赤道), where the climate is often mild and there are long hours of sunshine. The warmth of the land heats the air above, causing it to rise    1    tiny drops of water to fall as rain. The rainfall can reach at least 98    2    (inch) a year. This wet, warm world with plenty of sunlight is perfect for plants    3    (grow), so the trees grow fast with green leaves all the year round. The trees     4    (they) also have an effect on the climate. They gather water from the soil and pass it out into the air through their leaves. The wet air then forms clouds,    5    hang over the treetops like smoke. These clouds protect the forest     6    the daytime heat and night-time cold of nearby deserts,    7    (keep) temperatures fit for plant growth.

The rainforest is the ideal place for the growth of a wide     8    (vary) of trees. Most of them depend on animals to eat their fruits and spread their seeds. When the fruits     9    (eat), the seeds inside them go undamaged through animals’ stomachs and are passed out in their droppings.    10    seeds lying on the forest floor then grow into new trees.

There’s just a 1-in-3,700,000 chance that a person will be killed by     1     shark, but the fear is still enough to have swimmers worrying about     2     seen as prey(捕获物). Now, new research supports the long-standing theory       3     it’s a case of “mistaken identity” when great whites go in for a bite .

A team of biologists     4     (compare) videos of seals swimming with those of humans swimming. They then edited the clips to simulate a great white’s vision and found that from the ocean inhabitant’s point     5     view, humans do indeed have a strong resemblance to seals.

“Usually, great white sharks     6     (regard) as ‘mindless killers’ and fond of human flesh. However, this does not seem to be the case; we just look like     7     (they) food,” Laura Ryan, lead author of the study, told Live Science.

“They eat seals every day and bites on people are     8     (extreme) rare,” said Catherine MacDonald, a marine scientist at the University of Miami. “So if they’re not solving the problem visually, then how do we think they’re solving it?     9     (hit) the right targets, sharks could be relying on other senses, like the scent. If that’s the case,     10     (addition) studies on how great whites use those senses could help prevent further attack.”

Environmentalists are getting more     1     (worry) about the effects of fast fashion on the environment. Fast fashion is the mass     2     (produce) of clothes at a low cost. They are put in shops and online quickly     3     (create) a high demand. Factories make 100 billion items of clothing every year. The fast fashion business model is having     4     bad effect on the environment. Many of the clothes end up in landfills and are not recycled. Another bad effect on the environment     5     (cause) by the chemicals used to make the clothes. These cause health problems for people     6     (work) in clothes factories. The way people buy clothes is adding to the problem of clothing waste. Many years ago, people went to stores and tried clothes     7    . People took more time and thought more     8     (careful) before they bought clothes. They also wore them for longer. Today, people order cheap clothes on the Internet and if they don’t like     9     (they), they throw them away. Every year in Europe, four million tons of clothing ends up in the trash, less than one percent of     10     is recycled.
