A BBC film crew was working on the remote Lord Howe Island for a new wildlife documentary called Drowning in Plastic. They filmed many birds that 【小题1】(die) for no clear reason. After some research, they found out the truth — what caused 【小题2】 death of the birds was that their stomachs were literally too full of plastic. The documentary team also filmed biologists 【小题3】(work) on the island to save the birds. The scientists captured hundreds of chicks and removed plastic from their stomachs 【小题4】(give) them a chance of survival.

Are zoos necessary, or are they only bad to the animals? This is a question【小题1】causes disagreement among many animal scientists. Some, we may just call them Group A, believe that placing animals in a zoo is not good【小题2】them. These people think that all animals should 【小题3】(protect) from being hunted too much and left in 【小题4】(they) native land. They also advise people to be educated to know more about animals in the wild.【小题5】, scientists from Group B think differently. They say that modern zoos are designed very closely to【小题6】natural environment. One of their 【小题7】(strong) arguments(论点) is that certain animals, such as the panda from China and the white tiger from India,【小题8】 (be) not only protected from uncontrolled killing,【小题9】can give birth to babies under protection and in that way they may be saved from【小题10】(die) out. You are expected to express your opinions on this question.

Tibetan antelopes are very graceful animals, 【小题1】 live on the plains of Tibet, Xinjiang, and Qinghai. They are in danger because many of them are being hunted 【小题2】 (illegal) for their valuable fur. The population 【小题3】 (drop) by more than 50 percent between 【小题4】 1980s and 1990s. In order to save this species from 【小题5】 (die) out, the Chinese government placed it under 【小题6】 (nation) protection and some effective 【小题7】 (measure) have been carried out. As a result, the antelope population has recovered and in June 2015, the Tibetan antelope 【小题8】 (remove) from the endangered species list. However, the government will continue the 【小题9】 (protect) programmes because the threats to the Tibetan antelope have not yet disappeared. In fact, only when we learn to exist 【小题10】 harmony with nature can we stop being a threat to wildlife and to our planet.
