：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.B

2.D

3.Bsetout意為“出發(fā)，動(dòng)身”。

4.C所有的學(xué)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(dòng)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(dòng)。

Iammoved．我很感動(dòng)。

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

6.C

7.Dapplyto應(yīng)用；applyfor申請(qǐng)

8.A【句子大意】新打字機(jī)的價(jià)格是二手貨的三倍。

9.D

10.A

11.C

12.D解析：本題測試形容詞辨析。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)來描述，而我卻認(rèn)為它是這個(gè)計(jì)劃中最重要的部分。

13.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(xiàng)B是正確的?！揪渥哟笠狻磕汶y道還認(rèn)為他已經(jīng)忘掉了，是嗎?

14.D

15.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。

16.C

17.Ainparticular是固定搭配，意為“特別地”。

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

19.A解析：本題考虛擬語氣在名詞性從句中的用法。在“ask(advise，desire，ordersuggest，require，etc。)+the廣引導(dǎo)的從句中，謂語動(dòng)詞應(yīng)用“should+認(rèn)”，should可以省去，再結(jié)合語態(tài)，故A項(xiàng)正確。本句大意為：他們要求所有的必要文件都必須在月底之前交到校長辦公室。

20.A

21.價(jià)格決定資源的利用方式，是購買者之間對(duì)有限供應(yīng)的產(chǎn)品和服務(wù)進(jìn)行配給的手段。

22.你可以從這些書中挑選五本。
