But 考查連詞。句意：但你意識到每次享用一碗魚翅湯時，你就在殺死一整條鯊魚嗎？該句與上文是轉折關系，所以用but；句首單詞首字母大寫，故填But。3. the　考查冠詞。句意：當人們捕捉鯊魚時，他們割下它們的鰭，然后把鯊魚扔回海里。4. harmful　考查形容詞。句意：這種方法不僅殘忍，而且對環(huán)境有害。be harmful to對……有害。5. strongest 考查形容詞最高級。句意：許多人認為鯊魚永遠不會瀕臨滅絕，因為它們是它們食物鏈中最強大的。根據(jù)句意可知用形容詞最高級，故填strongest。6. are caught 考查時態(tài)和語態(tài)。句意：但事實上，每年大約有7 000萬條鯊魚被捕獲和交易。根據(jù)時間狀語every year可知用一般現(xiàn)在時。主語sharks與catch之間是被動關系，所以用被動語態(tài)，故填are caught。7. have fallen 考查時態(tài)。句意：在過去的20到30年里，某些種類的鯊魚的數(shù)量減少了90%多。根據(jù)時間狀語in the last 20 to 30 years可知用現(xiàn)在完成時，故填have fallen。8. groups　考查名詞的數(shù)。名詞group為可數(shù)名詞，前無冠詞，且根據(jù)后面的have可知用復數(shù)形式。9. to stop 考查非謂語動詞。句意：世界各地的環(huán)境保護組織，如WildAid和世界自然基金會，已經要求政府制定法律來阻止魚翅的銷售。根據(jù)句意可知，這里用不定式作目的狀語，故填to stop。10. for　考查短語。句意：到目前為止，沒有科學研究表明魚翅有益健康，所以為什么要吃它們呢？be good for對……有益。Ⅱ. 【語篇解讀】本文是一篇說明文。本文介紹了山地大猩猩的特點、生存環(huán)境及目前的處境等。1. G　根據(jù)上文“Mountain gorillas are strong，with long muscular arms and a big chest. They have thick black hair that protects them from the cold in high mountain areas.”以及后文“Although they are very strong，mountain gorillas are shy animals. They normally don’t attack humans.”可知，本段主要是關于山地大猩猩的特點的介紹，故G選項“一只大的雄性大猩猩可以達到近2米高”符合語境。2. B　根據(jù)后文可知，后文提到了雌性山地大猩猩的生育情況，介紹了雌性山地大猩猩會生育幾個幼崽，故B選項“雌性山地大猩猩生育幾個幼崽”符合語境。3.

They also eat insects but rarely drink water because there is enough moisture in the plants.”可知，后文主要介紹了山地大猩猩的飲食習慣，提到了山地大猩猩主要以植物為食，D選項中的plants對應后文中的plants。故D選項“至于食物，山地大猩猩主要以植物為食”符合語境。4. A　根據(jù)上文可知，本段主要講述了山地大猩猩所面臨的生存威脅，A選項中they指代上文的mountain gorillas，故A選項“它們受到多方面的威脅”符合語境。5. E　根據(jù)后文可知，后文提到了山地大猩猩所在的國家總是發(fā)生戰(zhàn)爭和其他沖突，所以推測要保護山地大猩猩很困難。故E選項“我們很難保護那些山地大猩猩”符合語境。Ⅲ. 【語篇解讀】本文是一篇記敘文。文章講述了作者的家鄉(xiāng)新奧爾良發(fā)生了一次可怕的颶風災難，人們失去了家園。但是新奧爾良的星星給了作者和家人們希望。一年后人們回到家園，星星又給了人們重建家園的信心。1.
