參考答案

1.D

2.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。

3.D

4.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?

5.C

6.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。

7.C

8.D解析：forgetdoingsth．忘了已做過某事。注意區(qū)別forgettodosth。忘了而沒有做某事。

9.A解析：shape意為“(女人的)姿態(tài)，身段”；form意為“形狀，形態(tài)”；appearance意為“外表，樣子”；body意為“身體”。由題意知應(yīng)選A。

10.B

11.C解析：本題考查倒裝虛擬語氣用法。本句是表示與將來事實相反，所以從句用wereto形式。句意為：如果他今天出發(fā)的話，他就會在星期五以前到達那里。

12.A

13.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。

14.Dapplyto應(yīng)用；applyfor申請

15.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。

16.D

17.D

18.C

19.A解析：反問疑問句的陳述部分是肯定式時，疑問部分用否定式。以letme或letus起始的反問疑問句，疑問部分用willyou或won'tyou，所以選項A是正確的。

20.D解析：上句責備瑪麗應(yīng)該做作業(yè)而不是坐到那兒看電視，下句是瑪麗對媽媽責備的一種辯解：“你說過電視是有教育意義的?！彼訢項正確。

21.I’vejustgraduatedfromcollege,andI’mlookingforaninterestingandwell-paidjob.
