：1.人們認(rèn)為淡水是取之不盡的

;2.實(shí)際上淡水是短缺的;3.我們應(yīng)當(dāng)怎么辦。

參考答案

1.A

2.A

3.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。

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

5.A

6.Bsetout意為“出發(fā)，動(dòng)身”。

7.Blaunch為“發(fā)射”講；其余為干擾項(xiàng)。

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

9.A

10.B

11.C

12.C解析：副詞so置于句首，句子應(yīng)該用倒裝語(yǔ)序，某人受傷用sb.beinjured來(lái)表示，故答案為C。

13.D

14.C

15.D解析：which修飾非限定性定語(yǔ)從句，指代前邊一句話。本題涉及句法知識(shí)——簡(jiǎn)單句、并列句和復(fù)合句。例如：Hehastwodaughters.Theyaredoctors.(簡(jiǎn)單句)Hehastwodaughtersandtheyaredoctors.(并列句)Hehastwodaughters,whoaredoctors．(復(fù)合句)

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

17.C

18.A解析：句意：她昏倒了。給她臉上澆些水，或許她會(huì)醒過(guò)來(lái)。本題考查詞組辨析。comeround：過(guò)訪，繞道而來(lái)，蘇醒過(guò)來(lái)；comeback：回來(lái)，恢復(fù)；comeagain：再說(shuō)一遍，重復(fù)一遍；comeout：出來(lái)，傳出。

19.D解析：本題測(cè)試形容詞辨析。四個(gè)選項(xiàng)的意思分別是“普通的”，“清楚的”，“正義的”，“僅僅的”。根據(jù)句意，D項(xiàng)正確。本句大意為：他僅僅把它作為一個(gè)細(xì)節(jié)來(lái)描述，而我卻認(rèn)為它是這個(gè)計(jì)劃中最重要的部分。

20.A【句子大意】新打字機(jī)的價(jià)格是二手貨的三倍。

21.A

22.D

23.Ainparticular是固定搭配，意為“特別地”。

24.B

25.D解析：從句中的問(wèn)句主謂不倒裝。從句的時(shí)態(tài)隨主句。我想知道那輛車(chē)的價(jià)格。

26.D

27.C
