六、作文(1題)71.一位學者將在你所在的社區(qū)做一個講座。請以社區(qū)委員會(NeighborhoodsCommittee)的名義寫一份通知。內(nèi)容包括：(1)誰做講座;(2)講座主題;(3)講座的時間、地點;(4)講座對象。

參考答案

1.B解析：takemeasures意思為“采取措施”，本句應(yīng)用被動語態(tài)。

2.D

3.C解析：much用在句中修飾比較級better。

4.A解析：while意為“雖然”；as意為“因為”；if意為“如果”；since意為“因為”。根據(jù)題意選A。

5.D解析：從句中的問句主謂不倒裝。從句的時態(tài)隨主句。我想知道那輛車的價格。

6.B解析：表示否定的副詞前置于句首，句子需要不完全倒裝，即助動詞提前。其余選項均可排除。除Notuntil外還有never，seldom，rarely，seldom，no，little，hardly，innotime等否定副詞或結(jié)構(gòu)放在句首時，句子需要部分倒裝。

7.A本題考查祈使句型：

【應(yīng)試指導(dǎo)】句意：Mary，到這里來，其余的人待在原處。根據(jù)句子的結(jié)構(gòu)可判斷出這是個祈使句。所以要用動詞原形開頭。Mary在句中不是

主語，而是“呼語”。

8.A解析：句意：她昏倒了。給她臉上澆些水，或許她會醒過來。本題考查詞組辨析。comeround：過訪，繞道而來，蘇醒過來；comeback：回來，恢復(fù)；comeagain：再說一遍，重復(fù)一遍；comeout：出來，傳出。

9.A解析：favor：幫助，一般用domeafavor；good：好處；help不與do搭配：kindness：善良。故選A。

10.C解析：副詞so置于句首，句子應(yīng)該用倒裝語序，某人受傷用sb.beinjured來表示，故答案為C。

11.B考查反義疑問句。原句應(yīng)是：youwouldthinkhehadhaveforgotten…反義疑問句的規(guī)則是陳述部分是肯定式，疑問部分應(yīng)是否定式。Wouldthink表示推測，疑問部分也應(yīng)選擇would。選項B是正確的?！揪渥哟笠狻磕汶y道還認為他已經(jīng)忘掉了，是嗎?

12.A解析：此題考查反意疑問句的用法。主句為祈使句，因此其反意疑問句用willyou。

13.D

14.B

15.D

16.B

17.D解析：本題考查動詞搭配。doone'shomework“做作業(yè)”；makemistakes“犯錯誤”。句意為：做作業(yè)，還要保證別犯錯誤。

18.C

19.B解析：此處是對將來情況的假設(shè)。虛擬條件句的謂語部分為should，had或were時，可把if省去，而把should，had或were放在從句的主語之前，構(gòu)成主謂部分倒裝。

20.C所有的學生都去看了昨天的魔術(shù)表演。它太令人不可思議了。這里主要考查的是動詞的現(xiàn)在分詞和過去分詞的不同用法。Sth．bedoing表示某一事物令人怎么樣。Sb．bedone表示某人處于某種狀態(tài)。例：Theletteristouching．這封信令人感動。

Iammoved．我很感動。

21.B解析：本題考查動詞固定搭配的用法。deprive后常接介詞of，表示剝奪什么。

22.B解析：本題考查固定搭配的用法。當否定詞位于句前時，得出結(jié)論應(yīng)用reach/achievein/arriveatconclusion，故選B。

23.A解析：根據(jù)上文提到“findone”，故下文中也應(yīng)填one，表示泛指。

24.D本題考查時態(tài)。

【應(yīng)試指導(dǎo)】句意：當你寫信回家的時候，請代我向你的妻子問好。在時間狀語從句中用一般現(xiàn)在時代替一般將來時。

25.C

26.B

27.C

28.A

29.Ainparticular是固定搭配，意為“特別地”。

30.B解析：theeducationsystem是主語，謂語動詞應(yīng)用單數(shù)；thedesiredresults意為“期望的結(jié)果”。

31.CanIhelpyou/WhatcanIdoforyou

32.EWouldyoulikemyhelp
