1、河北省承德市双滦区实验中学2021届高考英语一轮复习晚测训练6姓名:_ 班级:_ 得分: _第二部分:阅读理解(共两节,满分35分)第一节(共10小题;每小题2.5分,满分25分)阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。A The survival of about one fifth of the worlds vertebratesanimals with a backbone,is considered threatened, according to new research published in the journal Science. Thats
2、a large fraction of Earths animals, but this new study held some good news too. Conservation efforts by humans have slowed the loss of many species of amphibians(两栖动物), birds, and mammals. Losses in these groups would have been about 20 percent greater had it not been for recent actions of protectio
3、n.Among the animalconservation success stories is one about birds called Mauritius kestrels. In the 1970s, just four of these birds of prey were left in the world. Through a special breeding program, scientists were able to increase their number to about 1,000 and release them into the wild.Humpback
4、 whales(座头鲸) have benefited greatly from recent conservation efforts as well. They were once on the International Union for Conservation of Natures (IUCN)list of species threatened with extinction. But the species is now in less danger, thanks to laws that ban whale hunting. The IUCN even moved the
5、humpback into “species of least concern.”Over the past 100 years, the white rhino(犀牛) of South Africa has also made an amazing recovery because of habitat protection. The breed multiplied from just 50 animals to about 17,000. Their home has been turned into a protected area, safe from poachers and o
6、ther threats.Stuart Butchart, one of the authors of the new study in Science, is encouraged by the positive effects of conservation. But he says “Biodiversity (生物多样性)of species is in a desperate state. Its situation is getting worse. But our results show we can turn the situation around.”New conserv
7、ation policies hopefully are on the way. One hundred ninetythree countries recently met in Japan at the Convention on Biological Diversity to set concrete goals for preserving threatened wildlife and their habitats. Only 1 percent of oceans and 12 percent of land areas were protected under prior agr
8、eements. Two new goals set by the group are to designate(指定) 10 percent of the worlds oceans and 17 percent of land environments as protected areas to help increase endangeredanimal populations.21What can we learn from the passage?AThough there was a special breeding program, the number of Mauritius
9、 kestrels didnt increase.BConservation efforts should not only be made by human beings.CHumpback whales are not on the International Union for Conservation of Nature s list now.DBecause many groups are working to protect wildlife, natural habitats are in good condition.22Which of the following is NO
10、T mentioned in people s conservation efforts?AHabitat protection. BBreeding programs.CLaws of banning whale hunting. DCreation of studying organizations.23. The author uses some successful animalconservation examples to show that_.Aconservation worksBman conquers natureCanimals are more importantDla
11、w is fairCDA B It was a Sunday and the heavy storm had lasted all night. The morning after the storm, though, was beautiful: blue skies, warm air and a calm, inviting sea touching the shore gently.My father realised it was a good day for fishing and invited my sister and me to go with him. I was onl
12、y 14 and fishing had never been my thing, but I decided to go all the same. I m so glad I did.On the road to the harbour we could see the terrible destruction on the coast, but the harbour itself was in fairly good shape. After all, it was protected by the arms of a bay that had only one tiny channe
13、l to the sea. As we got on board, we noticed two big humps (脊背) in the distance.On approaching them, we saw it was a mother whale with her baby. We couldnt believe it there arent any whales along the coast here. The storm must have driven them across the ocean into the bay, in which the still water
14、was so badly polluted that nothing could survive.The little baby whale actually as big as our boatwas obviously stuck and could not move. The mother dived under the water and came up suddenly, making big whirlpools (漩涡) and waves. “She s trying to help her baby, but on the wrong side, ” my father sa
15、id. At this point, my father moved our boat in a semicircle to the other side and, heading the boat towards the baby whale, pushed it gently. With our several gentle pushes the big hump turned over and disappeared under water. Then it swam up right beside its mum. They struggled in their desperate a
16、ttempts to escape but missed the exit and started heading in the wrong direction. We hurried up to the whales and tried to lead them towards the bay channel. Slowly, they let us lead them, sometimes rising from the water right beside us to breathe and to give us a trusting look with those huge eyes.
17、 Once they hit their first part of clean water flowing straight from the sea, the mum gave us a wave with her tail and off they swam into the distance.In the excitement it had felt like only a few minutes, but we had been with those wonderful animals for almost an hour and a half. That was the simpl
18、e and lasting beauty of the day. Nearly four decades later, I still look back fondly to that golden day at sea.24The author says “Im so glad I did.” ( in Para. 2) because _.Ahe witnessed the whole process of fishingBhe enjoyed the beauty of the calm seaChe experienced the rescue of the whalesDhe spe
19、nt the weekend with his family25The harbour survived the storm owing to _.Athe shape of the harbourBthe arms of the bayCthe still water in the channelDthe long coast line26The mother whale failed to help her baby because _.Ashe had stayed in the polluted water for too longBthe whirlpools she had mad
20、e were not big enoughCshe had no other whales around to turn to for helpDthe waves pushed her baby in the wrong directionCBD C Thousands of eggs of the endangered Olive Ridley turtles(海龟) on the beach have failed to hatch this year because of the recent oil spill .An oil coat had spread over a seven
21、 km area near the nesting site off the Rushikulya beach after around eight tons of furnace oil leaked from an Essarowned vessel near Gopalpur port, 20 km from here, on April 12.Being pushed by high tide, the spilled oil spread to the coast. Villagers claimed that they had seen carcasses of adult tur
22、tles along the coast after the sea water had been contaminated. Around 155,000 of the rare Olive Ridleys had nested along the coastline in March while the mass hatching of eggs, which continued for a week, ended last week. “The authorities cleaned only 23 km stretch of the beach.”Many eggs were dama
23、ged due to the effect of oil deposits.“Moreover, many baby turtles failed to move out of the nest as the soil also got harder”, Sahu, who along with villagers of Purunabandha has been working in the turtle conservation programme since the last 16 years, said. Turtle expert Kartik Shanker also raised
24、 similar concerns.“The oil spill will have an effect on the mortality rate of the hatchlings. But scientifically, it is not possible to arrive at a mortality figure for it,”Shanker, a professor at the Indian Institute of Science, Bengaluru, said. Marine scientist Bijay Kumar Sahu said there was an i
25、mmediate need for a detailed multidiscipline faculty study on the longterm impact of the oil spill on the marine environment. State forest and wildlife officials, however, refuted(反驳) the claims. “The oil spill has had no effect on the hatching process. Oil was cleaned from the beach a long time ago
26、 and the issue is now a closed chapter,”the states Chief Conservator of Forests wildlife, Srivastava said.The mortality rate of the hatchlings is usually high with only one out of every thousand surviving to become an adult turtle. “Out of around 100120 eggs laid by a single female turtle, only abou
27、t 80 of them hatch. The newborns then face threats from predators like crows, jackals, kites, etc. They also get eaten up by sea predators,”wildlife activist Biswajit Mohanty said.27Many baby turtles couldn t get out of their nests after they were hatched because_.Atheir parents failed to find themB
