在日常生活中如何保护野生动植物呢，一起来看看文中提出了哪些做法。 Wildlife faces threats from habitat destruction, pollution and other human actions. Although protecting wildlife can seem overwhelming at times, even small actions in your own neighborhood can help protect many different animals. Create wildlife friendly areas in your backyard. You can choose native plants that can provide food and shelter to native wildlife. This will also help cut down on pollution. Add bird or bat houses to your yard or garden to attract and shelter these species. Avoid disrupting the natural ecosystem in your area. Nonnative plants or animals can destroy habitats, particularly if there is no natural predator to keep the species in check. Invasive plants can kill or disrupt native plants that provide food and shelter for wildlife. Have a greener lifestyle. By conserving water and fossil fuels， you will be helping to protect the wildlife around you. Take public transportation when you can, turn off electric devices when youre not using them. Become knowledgeable about what contributes to global warming, what disrupts migration patterns and habitats. Buy products that are wildlife friendly. Avoid products that are made from threatened or endangered animals. Keep in mind that some endangered animals are killed by traps, snares or hunters who are after other wildlife within the same habitat. Talk to or write to policymakers about protecting wildlife. Discuss ways to help animals with friends and family members. Limit family size. Population growth is one of the major factors in habitat destruction. By living in established city limits and limiting family size to around two children per family, the earths population will stabilize and native habitats can be protected. 【注】habitat n.

It is the smallest of the species of foxes, and quite a few people wish to raise it as a pet because of its appearance. However, this is very rare, as it needs special care and attention. Lets take a look at the basic information on the Fennec fox, including its physical appearance, natural habitat, and diet. Physical Appearance The Fennec fox is the smallest type of fox, with a body length of about 9.516 inches, and 6inchlong ears. It weighs only around one kilogram. It has a creamcolored, furry body, with a blacktipped tail. Their ears are the largest among all foxes relative to the body size, which not only provide them with great hearing, but also radiate the extreme desert heat and thus help to keep the body cool. Moreover, in order to walk on the hot sand, a Fennec foxs feet are covered with thick fur. Not only that, the feet also help in digging, as this animal lives under the ground. Habitat and Lifestyle The habitat of this animal is mainly in the Sahara Desert, and also in other parts of North Africa. The Fennec fox is usually active during the night. This character helps it deal successfully with the extreme heat in the desert. As an extremely social animal, it often lives in groups of ten and each group has its own land. This animal is, however, aggressive too, ready to attack, especially in the mating (交配) season, when they all compete with each other for a mate. Diet The Fennec fox is an omnivore (杂食动物). While it can survive on plants, it also needs other items such as insects, rabbits, birds and eggs. Getting used to living in the desert allows it to survive for long periods without any water. They are known to take in water when eating food, but will drink water if available. 篇章导读：本文是一篇说明文。文章主要介绍了耳廓狐的形态特征、栖息环 境、生活习性以及食性。 1What helps the Fennec fox survive in the desert? AThe small body size.BThe great hearing. CGetting active at night.DLiving in groups. 答案：C细节理解题。根据第四段中的“The Fennec fox is usually active during the night. This character helps it deal successfully with the extreme heat in the desert.”可知，耳廓狐通常在晚上活动，这一特点使它可以应对沙漠的酷热，故 选 C 项。 2The word “radiate” (Paragraph 3) is closest in meaning to _. Asend outBtake in Csuffer fromDturn down 答案：A词义猜测题。根据第三段中的“. radiate the extreme desert heat and thus help to keep the body cool.”可知，耳廓狐通过耳朵调节热量，保持身体凉 爽。保持身体凉爽应该是要散发热量，所以 radiate 的意思与 A 项接近。 3What can we learn about the Fennec fox in the passage? AIt seldom attacks others. BIts difficult to raise it as a pet. CIt can survive without any water. DIts the smallest animal in the desert. 答案：B推理判断题。根据第一段中的“However, this is very rare, as it needs special care and attention.”可知，耳廓狐作为宠物非常少见，因为它需要特 殊的护理，由此推断 B 项正确。根据第五段中的“This animal is, however, aggressive too, ready to attack”可知 A 项错误；根据最后一段中的“They are known to take in water when eating food, but will drink water if available.”可知 C 项错误； 根据第二段中的“The Fennec fox is the smallest type of fox .”可知，耳廓狐是最小 的狐狸，而不是沙漠最小的动物，故 D 项错误。 课后课时作业 完形填空 A thousand years ago Hong Kong was covered by a thick forest like the forests we now find in Malaysia and Thailand. As more and more _1_ came to live in Hong Kong, these trees were cut down and burnt. Now there is no forest left, _2_ there are still some areas covered with trees. We call these _3_. Elephants, tigers, monkeys and many other animals used to live in the _4_ forests of Hong Kong, and there were even crocodiles in the _5_ and along the coast. When people came to live in Hong Kong, the animals began to _6_ out. Early farmers grew rice and kept pigs and chickens in the valleys. They _7_ the trees and burnt them. They needed fires to keep themselves _8_ in the winter, to cook their food, and to keep away from dangerous animals. Elephants quickly disappeared because there was not enough _9_ for them. So did most of the wolves, and tigers. Monkeys, squirrels and many other animals soon died out in the same _10_. You might think that there are _11_ any animals in Hong Kong, except in the _12_. You might think there cant be any wild animals in such a _13_ place with so many cars and buildings. But there is _14_ a good deal of countryside in Hong Kong and New Territories, and there are still about thirtysix different kinds of animals living there. One of the most interesting of Hong Kongs _15_ is the barking deer. They are beautiful little creatures with rich, brown coat and a white patch under the tail. They look like deer but they are much _16_. They are less than two feet high. The male barking deer has two small horns but the female has none. They make a _17_ rather like a dog barking. Barking deer live in thick shrub (灌木) country and are very good at _18_. They eat grass and shrubs, mainly in the very early morning and late afternoon and evening. This is when you are most likely to see one but you will need to be very quiet and to have very _19_ eyes. In Hong Kong the barking deer has only one _20_ man. Although it is illegal, people hunt and trap these harmless little animals. As a result there are now not many left. There are a few on Hong Kong Island but none in the New Territories. 篇章导读：本文是一篇说明文。香港，这个世界闻名的繁华都市，曾是多种 动物的栖息地，由于人类的活动，它的原貌发生了改变。尽管如此，香港的郊区 依然生活着多种动物。 1A.peopleBchildren CladiesDwomen 答案：A由空格后的“live”可确定此处指“很多人来此居住” 。 2A.asBsince CthoughDbecause 答案：C根据空格前后的语意“现在没有森林了”和“还有一些地区由树 木覆盖”可以看出前后语意为转折关系。故选 C。 3A.desertBshades CfieldsDwoods 答案：Dthese 指代前文出现的“areas covered with trees”，这样的地方应称 之为“树林” 。 4A.thinBthick CshortDdying 答案：B由语境可以看出，此处是描述香港在人类到来之前森林繁茂的景 象。 thick forest 意为“繁茂的森林” 。 5A.riversBhills CskyDmountains 答案：A由前文的“crocodiles”以及空格后的“along the coast”可知，鳄鱼应 生活在河里。 6A.dieBlook CcomeDget 答案：A由于人类的出现，香港从前的样子被破坏了，动物也开始灭绝。 die out “灭绝” 。 7A.put upBlooked after Ccared forDcut down 答案：D由前后文可以看出，人们来到香港后，这里的自然环境开始遭到 破坏，树木被砍伐。 put up “建造，设立，张贴” ；look after “照看” ；care for “喜欢，照顾” ；cut down “砍倒” 。 8A.coldBcool CwarmDhot 答案：C根据空格前的“needed fires to keep themselves”可以看出，人们砍 伐树木是为了在冬天能够生火取暖。 9A.airBfood CwaterDclothes 答案：B由前后文可以看出，大象很快消失，因为它们没有足够的食物可 以吃。 10A.wayBroad CstreetDrail 答案：Ain the same way 意为“以同样的方式” 。 11A.neverBalways CnoDno longer 答案：D由该段后半部分“ But there is . and there are still about thirtysix different kinds of animals living there.”可以看出，前后文为转折关系，由此可知 此处句意为“你可能认为香港不会再有动物了” 。no longer “不再” 。 12A.zoosBshops CkitchensDparks 答案：A除了动物园其他地方就没有动物了。 13A.freeBbusy CbigDlarge 答案：B由空格后的“with so many cars and buildings”并结合实际情况可以 看出，香港是一个熙来攘往的城市。 14A.no moreBnearly CstillDhardly 答案：C由对该句内容的理解可知，虽然香港原来的自然环境遭到了一定 程度的破坏，但香港仍然有许多郊区，仍旧有很多种动物生活在那里。 15A.animalsBplants CfishesDbirds 答案：Abarking deer 是一种动物，故该空应选择 animals。 16A.greatBlarger CsmallerDheavier 答案：C由空格后的“They are less than two feet high.”可以看出，赤麂 (barking deer)个头并不大。 17A.noiseBvoice CsongDliving 答案：A由空格后的“rather like a dog barking”(更像是犬吠)可以看出此处 在描写赤麂的叫声。 noise 可指“声音” ，而 voice 强调“人的声音” 。 18A.barkingBeating CplantingDhiding 答案：D由后文的“. you will need to be very quiet and to have very _19_ eyes.”可知，赤麂非常善于躲避其他生物。 19A.commonBsharp CclearDbig 答案：B由于赤麂非常警觉，所以，要看到它们就必须有敏锐的眼睛。 20A.neighborBbrother CenemyDfriend 答案：C由后文的“people hunt and trap these harmless little animals”可以看 出，人类是赤麂的天敌。 阅读理解 Elephants are able to know the difference between a man and a woman, and can tell an adult (成年人) from a childall from the sound of a human voice. This is according to a study in which researchers played voice recordings to wild African elephants. The animals showed more fear when they heard the voices of adult Masai men. Usually Masai people hunt elephants, and this suggests that animals have grown to listen for and avoid them. Prof. Karen McComb and Dr Graeme Shannon from the University of Sussex led the study. They explained that in former research they had used similar experiments to show that elephants could tell from the sound of a lionwhether the animal was a female (雌性) or a more dangerous male (雄性) Prof. McComb wanted to find out if the animals used their very sharp sense of hearing to recognize danger from humans. The scientists recorded Masai men, women and children saying, in their own language, “Look, look over there, a group of elephants are coming.” They also recorded Kamba men saying this phrase. Masai people often come across elephants, which can result in violent (暴力的) hunting. Kamba people, however, mainly feed on agriculture, which does not generally bring them into violent touch with the animals. When the team played recordings of these different voices through a hidden speaker, they found that elephant family groups showed more fear in response to the voice of a Masai man than to a Kamba mans voice. And the adult male Masai voices encouraged far more of these defensive reactions than the voices of women or boys. 篇章导读：本文是一篇说明文，一项研究表明，大象能根据人类说话的声音 判断出人类的性别、是否为成人以及对它们的危险程度。 1An elephant can tell a man from a woman by sense of _.
