182. We found ___A____ necessary to protect the environment. A. it   B. this   C. that   D. what

　　【考點】 "主語+find+ it +adj. + to do sth"為一常用句型，意為"某人發(fā)現(xiàn)做某事……"，其中it為形式賓語(此時不可用this/that/one等代詞替換)，真實的賓語為后置的不定式短語。

　　183..中文：從戰(zhàn)爭開始時他就一直在那里工作。(誤)He has worked there since the war has begun.

　　(正)He has worked there since the war began.（since引導的從句表示過去的某時間點，應用一般過去時。）

　　184. 中文：他去年離開家我就一直沒有見過他。(誤)He left home last year and I did not see him since.

　　(正)He left home last year and I haven\'t seen him since.（since后面省去的是he left home last year，前面的句子要用完成時。）

　　185. 中文：我去看他們的時候他們在吃晚餐。(誤)They had supper when I went to see them.

　　(正)They were having supper when I went to see them.（他們在吃晚餐是在過去我去看他們的時間某一點上正進行的動作，應用過去進行時。）

　　中文：她兩個月前去澳洲了，她許多年前到過那里。(誤)She went to Australia two months ago. She has been there many years before.(正)She went to Australia two months ago. She had been there many years before.（many years before是從過去的某時之前算起的，表示過去的過去，要和過去完成時連用。）

　　186.Neither he nor you is good at English.（×）Neither he nor you are good at English.（√）

　　析：either... or...，neither... nor...，not only...，but also...等詞組連接句子的兩個主語時，謂語動詞遵循"就近一致原則"，即由靠近謂語的那個主語決定謂語的人稱和數(shù)用何種形式。

　　187. I can't help _____ the house this afternoon A. sweeping    B. sweep C. swept           D. with sweep

　　B。易錯選A，學生誤用了短語can't help  v-ing。但此題不是"忍不住"之意，而是"不能幫……"之意。

　　188.The lift is used to ____ up and down every day.A. going  B. went  C. go  D. gone

　　C．易錯選A，學生是根據(jù)短語be used to v-ing（習慣于…）做出的選擇。但此題的be used to是被動語態(tài)，不是"習慣于…"而是"被用來做……"。

　　189. My pen ____ better than yours. I may lend it to you.A. is written  B. wrote C. writes         D. is writing

　　C。易錯選A，學生認為"物"作主語時，應用被動語態(tài)。但此句中并不是pen"被寫"，不能用被動形式。

　　190.____ my visit to France, I arrived ____Paris the first. A. At, in        B. On, at  C. During, to    D. In, on

　　B。易錯選A，學生的根據(jù)是巴黎是大地方所以應用介詞in。但根據(jù)此題之意，巴黎是"我"訪問法國的第一站而非目的地。在"我"的訪問的行程中，巴黎只是旅途中的一個"點"，故宜用at。

　　191.- Could you tell them____?- Of course, she lives in Shanghai Road. (昆明市)

　　A. where Lily livesB. where Lily livedC. where did Lily liveD. where to live in

　　A。易錯選B，學生一看到could，就認為應該選過去時lived。但此題是表示委婉語氣，故用一般現(xiàn)在時

　　192. He hasn't heard from his friend ____ last month.

　　A. since      B. by the end of  C. for        D. until

　　A。易錯選B或D。not…until，和last month應與過去的某種時態(tài)，而不是現(xiàn)在的某種時態(tài)連用。

　　193. I didn't buy the dictionary yesterday ____ my  aunt would give me one. (河南)

　　A. until          B. because C. if             D. before

　　B。易錯選A，學生只是根據(jù)固定搭配not…until來選擇，而沒有去理解該句的意思。句意為因為姑姑要給我買一本，所以我不買了，是因果關系，不是時間關系。

　　194____ is your father?-The tall man with a pair of glasses under the tree. . A. Who  B. WhereC. What D. Which【解析】此題陷阱選項為A或B或C。如果不看語境把四個選項代入句中意思都很通順。答語意為"樹底下那個戴著眼鏡的高個子男人"。由此可知問句的意思應該為"哪一個是你父親"。因此正確答案為D。

　　195-What would you like to drink?-It doesn't matter. _______ will do. A. NothingB. EverythingC. Something D. Anything【解析】如果不看語境把四個選項代入句中意思都很通。其實，這里的語境為"你想喝點什么?""沒關系，任何東西都行"。正確答案為D。

　　196. -What is your favourite _______?-Summer. I can go swimming at that time.

　　A. festival B. season C. month D. weather【解析】如果不看語境，四個選項代入句中意思都很通順。由答語可知問句所問的是最喜愛哪個季節(jié)，因此正確答案為B。

　　197. It's _______ hot _______ cold all the year round in Kunming. It's called "Spring City. "

　　A. either, orB. neither, norC. both, andD. neither, or

　　【解析】此題陷阱選項為A或C。這是由于忽略語境造成的。如果不看下文中的It's called "Spring City. "那么從語法角度來看A、B、C三項都沒有錯。但在這里只有B項才符合語境要表達的意思。正確答案為B。

　　198.Don't throw waste paper on the ground. Please _______.

　　A. pick them upB. pick up themC. pick it upD. pick up it

　　【解析】此題陷阱選項為A。這是由于忽略語境造成的，如果不注意上文中的waste paper，就很可能誤選為A。由于waste paper是不可數(shù)名詞，應該用it來代替，故正確答案為C。

　　199. 1. Mr Li said, "Don't make such a mistake again, Tim." (改為間接引語)

　　Mr Li told Jim ______ ______ ______ such a mistake again.

　　not to make。直接引語為否定祈使句時，若改為間接引語，用ask / tell sb not to do sth句型，注意其中的Don't改成了not to。

　　200.Why didn't she pass the exam? I want to know... (改為含賓語從句的復合句)

　　I want to know ______ ______ ______ pass the exam

　　why, she didn't。注意賓語從句的詞序與陳述句的詞序相同，所以要說she didn't。

　　201.Jack's father asked him, "Have you packed your things?" (改為間接引語)

　　Jack's father asked him ______ he ______ packed his things.

　　if, had。將一般疑問句的直接引語改為間接引語，就是將其改為一個以if(是否)引導的賓語從句。賓語從句要用陳述句語序，主句中的謂語動詞是過去式時，賓語從句的謂語動詞也用過去式。

　　202.Hurry up, or you'll miss the early bus. (改為含條件狀語從句的復合句)

　　______ ______ hurry, ______ ______miss the early train.

　　If you, you will。"祈使句+and / or+陳述句"句型中的祈使句就相當于一個if引導的條件狀語從句。注意：改寫時因為前面用了連詞if，后面的連詞and / or要去掉。

　　203.This text is very difficult. I can't understand it. (合并為同義句)

　　This text is ______ difficult for me ______ understand.

　　too, to。因為too…to…意為"太……而不能……"正好與前面的意思相吻合。另外，改寫后的句子也可說成The text is so difficult that I can't understand it.

　　204.I know a little bit about Italy as my wife and I ____ there several years  ago.

　　A. are going　B. had beenC. wentD. have been

　　題干中前半句"know"，一般現(xiàn)在時；后半句出現(xiàn)"several years  ago"，明顯的表示過去的時間，所以選擇一般過去時"went"，答案C.本題很多同學都順著中文"去過"而誤選了"D. have  been"，是沒有掌握好語句中出現(xiàn)了具體過去時間這一關鍵。

　　205. The young girl sitting next to me on the plane was very nervous. She ____  before.

　　A. hasn't flown　B. didn't flyC. hadn't flown　D. wasn't flying

　　題干中前半句"was"，一般過去時；后半句最后出現(xiàn)"before"說明是在過去（was）之過去，前半句的"was"給出了選擇過去完成時的時間背景，因此選擇C.

　　206. By the time you get back， great changes ______ in this area.A.will take place B.will be taken place

　　C.are going to take place D.will have taken place

　　題干"By the time you get back"，是"到你（將來）回來時"，這里因為是時間狀語從句，將來時用一般時代替，因此后半句的時間應當使"將已經(jīng)"，故選擇D.

　　207.When their first child was born, they ______ for three years. A. had married   B. had been married  C. had got married    D. got married [解析★]選B。這道題考察過去完成時。看到for three years, 第一，馬上想到使用完成時，排除Ｄ。第二，動作必須是可延續(xù)性的，所以排除Ａ、Ｃ兩項。答案Ｃ。208.I was really anxious about you. You _____ home without a word. A. mustn't leave    B. shouldn't have left        C. couldn't have left        D. needn't leave  [解析★★]選B。 這道題情態(tài)動詞+have done 表示"對過去發(fā)生的事件的推測"。shouldn't have done 表示"本不該做某事，但是卻做了。"所以選B最合適。C. couldn't have done 表示"過去不可能發(fā)生的事"。

　　209. When all the work ______, you may go back home. A. finishes      B. has finished     C. is finished    D. will be finished[解析]選C?？疾靸蓚€語法點：第一考察主將從現(xiàn)，主句使用may + 動詞原形，相當于一般講來時，從句應該使用一般現(xiàn)在時，所以A、C兩項入圍。第二考察被動語態(tài)。Work 和finish 的關系是動賓關系，因work（工作）自己本身不能發(fā)出finish這個動作。所以用被動語態(tài)。答案是C

　　210.Lucy and I are classmates. We _______ in Class One. A. all areB. are allC. both areD. are both【解析】此題容易誤選A或C。這里受到漢語思維的影響引起的，譯成漢語正好是"我們都在一班"。表示兩者都要用both，both一般放在be動詞、情態(tài)動詞或助動詞之后，行為動詞之前。正確答案為D。

　　211.If there are ______ trees,the air in our city will be _______cleaner.(more/fewer/much)

　　橫線后trees是可數(shù)名詞的復數(shù)形式，只能在修飾名詞的復數(shù)的fewer和more中選擇，根據(jù)句意選擇"更多more"；而后面cleaner往往學生會以為是個不可數(shù)名詞而選擇much，其實后面是clean個形容詞，而且其后er表示它是形容詞的比較級，只有much才能修飾形容詞的比較級。

　　212.What does the word "alone" mean?=What's the ___________  __________ the word "alone"?

　　上句中mean作動詞，下句中meaning作名詞，固定搭配："the meaning of……的意思"，學生容易想到meaning，而忽視了后面的介詞的搭配，容易寫成：off/for

　　Study hard and your dream __________.學生看到了"and"會以為是前后動詞時態(tài)對照，會寫come true/comes true，選will come true，是因為它是以下句子的縮略：If you study hard, your dream will come true

　　When Martin visited Beijing for the first time,he __________ the city.大多數(shù)學生容易寫成：was falling in love with/falling in love with分析：句中有when還有暗示 visited，學生很容易聯(lián)想到第三單元的從句，而選擇上面的答案。 fell in love with"愛上"，是暫時性動詞，應該選用一般過去時。
