It was a village in India. The people were poor. However, they were not unhappy. After all, their forefathers 【小题1】 (live) in the same way for centuries.

Then one day, some visitors from the city arrived. They told the villagers there were some people elsewhere 【小题2】 liked to eat frog’s legs. However, they did not have enough frogs of their own, and so they wanted to buy frogs from other places.

This seemed like money for nothing. There were millions of frogs in the fields around, and they were 【小题3】 use to the villagers. All they had to do was to catch them. Agreement was reached, and the children 【小题4】(send) into the fields to catch frogs. Every week a truck arrived to collect the catch and hand over the money. For the first time, the people were able to dream of a better future. But 【小题5】 dream didn’t last long.

The change was hardly noticed at first, but it seemed as if the crops were not doing so well. More worrying was that the children fell ill more often, and, there seemed to be more insects around lately.

The villagers decided that they couldn’t just wait to see the crops failing and the children getting weak. They would have to use the money earned 【小题6】(buy) pesticides (杀虫剂) and medicines. Soon there was no money left.

Then the people realized 【小题7】 was happening. It was the frog. They hadn’t been useless. They had been doing an important job—eating insects. Now with so many frogs 【小题8】(kill), the insects were increasing more rapidly. They were damaging the crops and spreading diseases.

Now, the people are still poor. 【小题9】 in the evenings they sit in the village square and listen to sounds of insects and frogs. These sounds of the night now have a much 【小题10】(deep) meaning.

Bird-watching, a hobby favored by many westerners, has been included in a public benefit program “Park Classes” in Wuhan schools. In the past six years, the program 【小题1】 (carry) out over 3,000 activities in Wuhan’s thirty urban parks, 【小题2】 (cover) all of the city’s primary schools and welcomed by over one million students. Buried in books and having little access to the outside world, many students don’t have the 【小题3】 (little) idea of what nature really is. This program is designed to enhance the awareness of environmental protection among school kids, 【小题4】often feel greatly refreshed by appreciating the grace of the adorable creatures through cameras.

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

“It’s very meaningful,” said Li Chenliang, 【小题9】 eighth grader from this project. “I have learned a lot of knowledge that cannot be 【小题10】 (direct) got from books. I should make full use of the city’s ecological advantages and get more chances to get closer to nature.”

Do you have a pet? 【小题1】 you do, congratulations, you are likely to have a 【小题2】 (good) mental state than those who don’t, reported Time magazine.

One study shows that 【小题4】 (pet) living creatures can help people with 【小题5】 (anxious), while animal toys have no effect at all.

Other researches studied the effect of pets 【小题8】 children who have difficulty reading. When the children 【小题9】 (ask) to read aloud to a dog and 【小题10】 (it) trainer, they were less upset.
