【解析】

偶然因?yàn)榇颢C放到自然中的狐貍和兔子，成為當(dāng)?shù)氐暮οx。政府也在想各種辦法來控制數(shù)量。

【1】句意：澳大利亞的害蟲是兔子，由一個(gè)移民者為了打獵運(yùn)動(dòng)放到野外而引入的。

discovered發(fā)現(xiàn)；introduced引入；shown顯示；killed殺害。根據(jù)“…who released 24 into the wild for sport hunting.”可知這些兔子是為了打獵運(yùn)動(dòng)放到野外而引入澳大利亞的，因此B選項(xiàng)符合句意。故選B。

【2】句意：1950年兔子疾病的傳播減少了數(shù)量，但是直到1997年另一種疾病傳播的時(shí)候害蟲的數(shù)量才最終得到控制。

sadness悲傷；struggle斗爭(zhēng)；disease疾病；tiredness疲勞。根據(jù)“...cut the number...以及“... the spread of another disease...”此空表示一種疾病的傳播。故選C。

【3】句意：現(xiàn)在兔子仍然保持一個(gè)驚人的數(shù)量2億，這導(dǎo)致農(nóng)田的流失。

kept保持；remained保持；left留下；pushed推。結(jié)合句意可知此處表示“保持”，A和B選項(xiàng)均有“保持”的含義，但remain強(qiáng)調(diào)“繼續(xù)停留于一處或保持原狀態(tài)、情況性質(zhì)而不改變”。故選B。

【4】句意：維多利亞州提供每只狐貍尾巴5.6美元的獎(jiǎng)金，在短短幾個(gè)月已經(jīng)收集了25000條。

catches抓�。�includes包括；offers提供；collects收集。根據(jù)此句的賓語prize可知，此空表示“提供（獎(jiǎng)金）”。故選C。

【5】句意：科學(xué)家建議他們應(yīng)該運(yùn)輸一些野狗，野狗是兔子和狐貍的天敵。

suggest建議；solve解決；discover發(fā)現(xiàn)；explain解釋。根據(jù)“Now the government is paying more attention to this problem. ”可知政府正在關(guān)注這個(gè)問題，因此科學(xué)家提示建議應(yīng)該怎么辦。A選項(xiàng)符合句意。故選A。

【6】句意：但是怎么控制他們的數(shù)量也是一個(gè)問題。

letter信件；name名字；note字條；number數(shù)量。根據(jù)第一段和第二段介紹兔子和狐貍成為他們的威脅，因此如何控制他們的數(shù)量是關(guān)鍵問題。故選D。

完形填空題并不是單純考查語法，也是考查學(xué)生綜合運(yùn)用語言的能力。因此，必須選擇符合語法結(jié)構(gòu)并能使上下文意義連貫的答案。有時(shí)候設(shè)置的選項(xiàng)具有迷惑性，如果單從語法角度分析，每個(gè)選項(xiàng)都是正確的，但是通過語境判斷，只有一個(gè)選項(xiàng)能夠傳達(dá)文章意思。因此我們要回顧上文，兼顧下文，在文中尋找相關(guān)的線索或提示，從而確定答案。注意固定搭配，本文考查詞匯辨析較多，就需要考生領(lǐng)會(huì)文章的主旨大意，然后通過前后句練習(xí)判斷用詞。并且詞匯量的掌握也非常重要。
