Often working at night, the poachers shoot whole herds of antelopes at a time, 【小题3】(leave) only the babies, whose wool is not worth so much. The animals are skinned on the spot and the wool taken to India, 【小题4】 it is made into the shawls.

These years, our government began to take an active part in protecting antelopes. Police are getting tough 【小题5】 the dealers. Officials working in the reserve are also helped by volunteers who are ready for difficult conditions of life. As a result, the antelope population began to grow again.

A kind of insect gets its name for the body shape, which resembles a long stick. Such an amazing 【小题1】 (appear) helps it successfully hide from predators(捕食者) in the branches of trees. These creatures 【小题2】 (call) stick insects. Often called walking sticks, they live on every continent except Antarctica. They can be smaller than an inch or longer than 【小题3】 18-inch ruler.

There are some other ways stick insects use to defend 【小题4】 (they). Some can hit attackers with their spiny legs. Others spray something in no time 【小题5】 burns an attacker’s eyes. And some just taste bad. The Peruvian stick insect is one of them. This stick insect is 【小题6】 (easy) to see because it has red, yellow, and black markings than others. These bright colors are a warning to predators, who know it discharges something with an unpleasant smell when 【小题7】 (attack).

Stick insects are mostly nocturnal, which means they are active at night, when they spend their time eating leaves. Darkness makes it harder for most predators 【小题8】 (discover) them. However, darkness doesn’t protect stick insects 【小题9】 one super set of insect hunters, insect-eating bats. These bats use echolocation(回声定位) to find yummy bug dinners. And stick insects are 【小题10】 (absolute) on the menu as something these bats want to eat!

Alice, a shark that lives at the National Sea Life Center in England, did not start out life as a vegetarian. When she 【小题1】(bring)in from Florida in 2009, she was happily eating any seafood. 【小题2】, that changed in a few months, and she suddenly stopped eating completely. Deeply 【小题3】 (concern), the center officials took her in for an X-ray, 【小题4】 showed that a fishing hook was hiding deep inside her mouth. So they took her to see a doctor, who realized the only way to save the shark was performing【小题5】rather risky operation.【小题6】(fortune), things went really well. But just when everybody was happy about the shark's recovery, the history-making shark began changing her eating habit, instead, 【小题7】(prefer) to use her sharp teeth to eat vegetables! Although this may sound good, it is not really good 【小题8】 Alice's health because vegetables can not provide enough protein that she needs to survive. Shark experts all over the world are confused at Alice's 【小题9】 (behave) and they guess that 【小题10】 may have something to do with the wound the hook caused. But unless she speaks up, nobody is really going to know the real reason.
