【文章內容簡介】 perfected now.[][分析]首先，根據(jù)句子的時間狀語now判斷使用現(xiàn)在進行時；其次，perfected是過去分詞，主語是物，根據(jù)句意判斷使用被動語態(tài)?，F(xiàn)在進行時的被動語態(tài)基本形式是be+ being+過去分詞。[答案] are being developed[例19] This popular sports car_______________(正在生產(chǎn)出來)out at the rate of a thousand a week.[][分析]①根據(jù)句意使用被動語態(tài)，現(xiàn)在進行時。其基本形式是be+ being+過去分詞。②“生產(chǎn)出來”可用詞組turn out。[答案] is now being turned[例20] Though a skilled worker, ___________________(他被公司解雇了)last week because of the economic crisis.[][分析]考查被動語態(tài)和一般過去時態(tài)。由時間狀語last week判斷用一般過去時。謂語動詞的基本形式為was/were+過去分詞，本句主語是單數(shù)人稱，因此用was +過去分詞。[答案] he was laid off/dismissed/ fired/sacked by his pany[例21] Many Americans live on credit, and their quality of life___________(是用他們能夠借到多少來衡量的), not by how much they can earn. [][分析]①使用被動語態(tài)，陳述客觀事實，時態(tài)為一般現(xiàn)在時。謂語動詞的基本形式為am/is/are+過去分詞。②根據(jù)句意，待譯內容的句子結構應與后半句“not by how much they can earn”（由how引導的名詞性從句作介詞by的補足成分）保持一致。[答案] is measured by how much they can borrow[例22] Our efforts will pay off if the results of this research ___________ (能應用于新技術的開發(fā)).[][分析]①從句的主語是物，根據(jù)句意判斷須使用被動語態(tài)。②“應用于”用動詞短語apply to表達。[答案] can be applied to the development of new technology五．從句從句的重點是定語從句、名詞性從句和狀語從句。1．定語從句要注意的兩個?？碱愋褪牵簍hat引導的定語從句和“介詞+關系代詞”引導的定語從句。as引導非限制性定語從句，相當于which引導的非限制性定語從句，但as位置比較靈活，它可以出現(xiàn)在句首句中和句尾。而which通常位于句尾，不能放在句首。例如：He is from Xi’an, as you know. 相當于He is from Xi’an, which you know. 也可以替換為As you know, he is from Xi’an.2．名詞性從句：顧名思義，名詞性從句在句中的功能相當于名詞詞組，在復雜句中充當主語、賓語、表語、同位語等，按其句法功能，一般可分為主語從句、賓語從句、表語從句和同位語從句。按其引導詞的不同又可分為兩大類：一類是由從屬連詞that引導，另一類是由what, which, who, whom, whose, whoever, whatever, whichever等連接代詞和how, when, where, why等連接副詞引導。復習中，大家應特別注意以wh詞引導的名詞性從句的具體用法，這也是考試的常見考點。3．狀語從句中一些特殊的引導詞要特別注意。例如：as/so long as（只要）, even if（即使）, even though（盡管，雖然）, in case/for fear that/lest（以防，萬一，以免）, in that（因為，由于）, no matter+wh疑問詞和wh疑問詞+ever（兩者意思都是“無論……”“不管……”），now that（既然，由于）, provided（假如）。[例23] The prevention and treatment of AIDS is_________________(我們可以合作的領域). [] [分析] 本題主要考查定語從句的用法。關系副詞選擇用where或 in which均可。[答案] the field (where) we can cooperate。 the field in which we can cooperate。 one field of our cooperation[例24] I am going to pursue this course,________________(無論我要作出什么樣的犧牲).[][分析] 考查“no matter+wh疑問詞”或“wh疑問詞+ever”引導的讓步狀語從句。若“wh疑問詞+ever”引導名詞從句，則不可用“no matter+wh疑問詞”替換?！盁o論/不管什么”用no matter what 或whatever。[答案] no matter what sacrifice I will have to make。 whatever sacrifice I will make。 no matter how much I will sacrifice [例25] Leaving one’s job, _______________(不管是什么工作), is a difficult change, even for those who look forward to retiring.[][分析] 分析同例24題。 [答案] no matter what job it is。 whatever job it is。 no matter what the job is六．倒裝結構倒裝分為全部倒裝和局部倒裝。全部倒裝就是整個謂語置于主語之前；局部倒裝是指謂語中的一部分，如情態(tài)
