35、overnments cleaned up their beaches. 答案：Under pressure Ⅳ.閱讀理解 The Fennec fox is also known as the desert fox since it survives in the Sahara Desert (沙哈拉沙漠). 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

36、 is very rare, as it needs special care and attention. Let's 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 9.5－16 inches, and 6-inch-l

37、ong ears. It weighs only around one kilogram. It has a cream-colored, furry body, with a black-tipped 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 c

38、ool. Moreover, in order to walk on the hot sand, a Fennec fox's 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 Af

39、rica. 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, especiall

40、y in the mating (交配) season, when they all compete with each other for a mate. Diet The Fennec fox is an omnivore (雜食動物). 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 w

41、ithout any water. They are known to take in water when eating food, but will drink water if available. 　 篇章導讀：本文是一篇說明文。文章主要介紹了耳廓狐的形態(tài)特征、棲息環(huán)境、生活習性以及食性。 1．What helps the Fennec fox survive in the desert? A．The small body size. B．The great hearing. C．Getting active at night. D．Living in groups. 答案

42、：C　細節(jié)理解題。根據(jù)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動，這一特點使它可以應對沙漠的酷熱，故選C項。 2．The word “radiate” (Paragraph 3) is closest in meaning to ________. A．send out B．take in C．suffer from D．turn do

43、wn 答案：A　詞義猜測題。根據(jù)第三段中的“... radiate the extreme desert heat and thus help to keep the body cool.”可知，耳廓狐通過耳朵調節(jié)熱量，保持身體涼爽。保持身體涼爽應該是要散發(fā)熱量，所以radiate的意思與A項接近。 3．What can we learn about the Fennec fox in the passage? A．It seldom attacks others. B．It's difficult to raise it as a pet. C．It can survive wit

44、hout any water. D．It's the smallest animal in the desert. 答案：B　推理判斷題。根據(jù)第一段中的“However, this is very rare, as it needs special care and attention.”可知，耳廓狐作為寵物非常少見，因為它需要特殊的護理，由此推斷B項正確。根據(jù)第五段中的“This animal is, however, aggressive too, ready to attack”可知A項錯誤；根據(jù)最后一段中的“They are known to take in water when

45、eating food, but will drink water if available.”可知C項錯誤；根據(jù)第二段中的“The Fennec fox is the smallest type of fox ...”可知，耳廓狐是最小的狐貍，而不是沙漠最小的動物，故D項錯誤。 課后課時作業(yè) Ⅰ　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.

56、 B．road C．street D．rail 答案：A　in the same way意為“以同樣的方式”。 11．A.never B．a(chǎn)lways C．no D．no longer 答案：D　由該段后半部分“ But there is ... and there are still about thirty-six different kinds of animals living there.”可以看出，前后文為轉折關系，由此可知此處句意為“你可能認為香港不會再有動物了”。no longer “不再”。 12．A.zoos B．shops C．kitchens D．par

57、ks 答案：A　除了動物園其他地方就沒有動物了。 13．A.free B．busy C．big D．large 答案：B　由空格后的“with so many cars and buildings”并結合實際情況可以看出，香港是一個熙來攘往的城市。 14．A.no more B．nearly C．still D．hardly 答案：C　由對該句內容的理解可知，雖然香港原來的自然環(huán)境遭到了一定程度的破壞，但香港仍然有許多郊區(qū)，仍舊有很多種動物生活在那里。 15．A.animals B．plants C．fishes D．birds 答案：A　barking deer是一種動物

59、g 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。 19．A.common B．sharp C．clear D．big 答案：B　由于赤麂非常警覺，所以，要看到它們就必須有敏銳的眼睛。 20．A.neighbor B．brother C．enemy D．friend 答案：C　由后文的“people hunt and trap these harmless little animals”可以看出，人類是赤麂的天敵。 Ⅱ　閱讀理解 Elep

60、hants are able to know the difference between a man and a woman, and can tell an adult (成年人) from a child—all 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 voic

61、es 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

62、that elephants could tell from the sound of a lion—whether 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

63、, 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

64、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 man's voice. And the adult male Masai voices encouraged far m

65、ore of these defensive reactions than the voices of women or boys. 篇章導讀：本文是一篇說明文，一項研究表明，大象能根據(jù)人類說話的聲音判斷出人類的性別、是否為成人以及對它們的危險程度。 1．An elephant can tell a man from a woman by sense of ________.

66、o know the elephants' special ability? A．By watching the elephants in the zoo. B．By playing voice recordings to them. C．By recording the behaviors of elephants. D．By communicating with them in a special way. 答案：B　細節(jié)理解題。由第一段最后一句“This is according to a study in which researchers played voice recordings to wild African elephants.”可知，研究人員通過給野生非洲大象播放錄音，發(fā)現(xiàn)其有這種能力。故選B。 3．We can learn from the passage that elephants are especially afraid of ________. A．Masai men B．Masai women C．Kamba men D．Kamba
