5、t. slowly, the number of some animals in danger is growing.本文是一篇關(guān)于動(dòng)物保護(hù)的說明文。目前，世界范圍內(nèi)很多動(dòng)物的數(shù)量正在不斷下降，保護(hù)瀕危動(dòng)物刻不容緩。保護(hù)動(dòng)物不僅是為動(dòng)物，也是為我們?nèi)祟愖约旱纳婵紤]。幸運(yùn)的是，現(xiàn)在有的國家已經(jīng)開始行動(dòng)，例如成立保護(hù)組織或制定法律等對(duì)瀕危動(dòng)物進(jìn)行有效的保護(hù)。1what is the best title for the passage?asave the animals buseful animalsclaws for animals danimals in danger答案：a解析：標(biāo)題歸納題

6、。文章提到動(dòng)物面臨的生存現(xiàn)狀、保護(hù)動(dòng)物的必要性以及目前一些國家對(duì)野生動(dòng)物采取的保護(hù)措施等都體現(xiàn)了保護(hù)動(dòng)物的主題，故文章標(biāo)題應(yīng)是“保護(hù)動(dòng)物”。2animals are important to us mainly because _.athey give us a source of foodbthey are beautiful and lovelycthey keep the balance of naturedthey give us a lot of pleasure答案：c解析：細(xì)節(jié)理解題。根據(jù)第四段中的“animals are more than.in the balance of

7、nature.”可以看出，每一種動(dòng)物的存在都是有道理的，都是為了維持自然界的平衡。3what is the meaning of the underlined word “multiplied” in the passage?abecame more. bbecame less.cturned black. date food.答案：a解析：詞義猜測題。由畫線詞所在的段落可以看出，當(dāng)鷹的數(shù)量因人類的捕殺而減少時(shí)，糧食就會(huì)受到老鼠的嚴(yán)重毀壞。沒有鷹對(duì)老鼠的捕殺，老鼠的數(shù)量自然是增長很快，即“變得更多”。4we can infer from the passage that _.apeople h

8、ave known the importance of animal protection since a long time agobanimals play an important role in people's lifecthe number of hawks is on the decreasedmany countries passed laws forbidding the killing of any animal答案：b解析：推理判斷題。根據(jù)第一段和第四段的描述可以看出，此前人們對(duì)于動(dòng)物的保護(hù)并不關(guān)注，當(dāng)然也并未意識(shí)到保護(hù)動(dòng)物的重要性，故可排除a項(xiàng)。通過對(duì)文章第四段

9、的理解可以得知?jiǎng)游镌谌藗兊纳钪衅鹬匾饔?，故b項(xiàng)正確。文中提到鷹的數(shù)量由于人類的捕殺而減少，但并非現(xiàn)在的情況，故可排除c項(xiàng)。d項(xiàng)中提到許多國家制定了法律來禁止對(duì)一切動(dòng)物的捕殺，忽略了文中on the danger list這個(gè)說法，故該項(xiàng)是不對(duì)的。bpassenger pigeons (旅鴿) were the most common birds in all of north america in the 1800s. it was common to see large groups of passenger pigeonsgroups that made a sound like a
