3.可能的解決措施

參考答案

1.C如果你正逐步遠(yuǎn)離鐘塔，你將會(huì)聽到鐘表的嘀嗒聲逐漸減弱，直到聽不到。

［考點(diǎn)］定語(yǔ)從句

【精析】C分析句子結(jié)構(gòu)可知，空處引導(dǎo)定語(yǔ)從句，先行詞apoint在此指某一點(diǎn)，表示地點(diǎn)，因此應(yīng)用關(guān)系副詞where引導(dǎo)從句，并在從句中作地點(diǎn)狀語(yǔ)。故選C

2.B他是否來還不確定。

［考點(diǎn)］名詞性從句

【精析】B分析句子結(jié)構(gòu)可知，本句為主語(yǔ)從句，空格處應(yīng)填入意為是否的詞，排除C、D兩項(xiàng)。if引導(dǎo)的主語(yǔ)從句不能位于句首，所以排除A項(xiàng)。故選B

3.B他有兩個(gè)女兒，愛麗絲和莎拉，前者嫁給了一位考古學(xué)家。

［考點(diǎn)］詞義辨析

【精析】Byoung:年輕的；former:前者的；elderly:上了年紀(jì)的，稍老的；old:老的。根據(jù)句意可知，選B

4.C不管你是誰，都必須遵守校規(guī)。

［考點(diǎn)］狀語(yǔ)從句

【精析】C分析句子結(jié)構(gòu)并結(jié)合選項(xiàng)可知，空處為讓步狀語(yǔ)從句，應(yīng)用Nomatterwho引導(dǎo)，相當(dāng)于Whoever,意為無論誰，任何人。根據(jù)句意可知，題干中的狀語(yǔ)從句應(yīng)用陳述語(yǔ)序，所以可排除D項(xiàng)。故選C

5.A她通過考試的希望很渺茫。

［考點(diǎn)］詞義辨析

【精析】Achance:概率,機(jī)會(huì)，可能性;opportunity:機(jī)會(huì),指可以達(dá)成某種目標(biāo)的機(jī)會(huì),暗含期許和期望;question:問題，難題。根據(jù)句意可知,選A

6.DD句意：如往常一樣，有三分之一的工人已經(jīng)超額完成了生產(chǎn)計(jì)劃。定語(yǔ)從句題。題干全句被逗號(hào)分隔成了兩個(gè)部分，逗號(hào)前面的部分缺少主語(yǔ)，而后面的部分則是一個(gè)完整的句子，兩者之間沒有連詞連接，因此可以判斷前面應(yīng)是一個(gè)非限制性定語(yǔ)從句。as可引導(dǎo)非限制性定語(yǔ)從句，在句中可以充當(dāng)主語(yǔ)或賓語(yǔ)，通常放在句首或句尾

7.B我講英語(yǔ)不僅非常認(rèn)真而且還很清楚。

［考點(diǎn)］固定用法

【精析】Bnotonly…but（also）為固定用法，意為不僅……而且……，also可以省略。故選B

8.D

9.C我打算去上海過寒假，我有親戚在那兒。

［考點(diǎn)］定語(yǔ)從句

【精析】C分析句子結(jié)構(gòu)可知，空處引導(dǎo)非限制性定語(yǔ)從句，修飾地點(diǎn)狀語(yǔ)Shanghai，且從句中缺少地點(diǎn)狀語(yǔ)，所以應(yīng)用where引導(dǎo)。which和when能引導(dǎo)非限制性定語(yǔ)從句，但which在從句只能作主語(yǔ)、賓語(yǔ)等成分，when在從句中只能作時(shí)間狀語(yǔ)；nevertheless：然而，均不符合題意

10.A重要的是有個(gè)大人來照顧這個(gè)小男孩。

［考點(diǎn)］虛擬語(yǔ)氣

【精析】AItisimportantthat引導(dǎo)的主語(yǔ)從句中常用虛擬語(yǔ)氣，謂語(yǔ)動(dòng)詞的形式為should+動(dòng)詞原形，且should可以省略。故選A

11.B新技術(shù)能使我們的產(chǎn)量翻番。

［考點(diǎn)］詞義辨析

【精析】Bsuggest：暗示，建議；enable：使能夠，使可能，常用于enablesb.todosth.；persuade：允許，常用于persuadesb.todosth.；make：做，使產(chǎn)生，常用于makesb.dosth.。根據(jù)句意及用法可知，選B

12.A這位工程師建議我們通過技術(shù)革新提高生產(chǎn)率。

［考點(diǎn)］虛擬語(yǔ)氣

【精析】A在insist,suggest,advise,demand，order等表示要求、建議、命令等含義的動(dòng)詞后面所跟的賓語(yǔ)從句中要用虛擬語(yǔ)氣,從句的謂語(yǔ)動(dòng)詞應(yīng)用should+動(dòng)詞原形的形式,should可以省略。根據(jù)句意可知,we和raise之間為邏輯上的主謂關(guān)系，所以應(yīng)用主動(dòng)語(yǔ)態(tài)。故選A

13.B當(dāng)他真的做錯(cuò)事時(shí)，他愿意去道歉。

［考點(diǎn)］詞義辨析

【精析】Bapply:申請(qǐng),適用;apologize:道歉;relieve:解除，減輕;relate：涉及，認(rèn)同。根據(jù)句意可知，選B

14.A當(dāng)陳述句部分是由Let's引出的祈使句時(shí)，其后的反意疑問句部分通常應(yīng)用shallwe；當(dāng)陳述句部分是由Letus引出的祈使句時(shí)，其后動(dòng)詞所表示的動(dòng)作不包括聽話人在內(nèi)，反意疑問句部分通常應(yīng)用willyou。本句陳述句部分是由Let's引出的祈使句，所以A項(xiàng)正確。
