1.Over a third of the population was estimated _________( 沒(méi)有機(jī)會(huì)享受醫(yī)療保健服務(wù))

to have no access to the health service
【解析】本題考查對(duì)不定式和have(no)access to的掌握。空格處在句中作主語(yǔ)補(bǔ)足語(yǔ)，不定式變成被動(dòng)語(yǔ)態(tài)以后，都必須加上to have(no)access to意為“(沒(méi))有接近(或進(jìn)入、享用)的機(jī)會(huì)”。

2.Surrounded by the police, the kidnappers___________( 沒(méi)有選擇，只能當(dāng)場(chǎng)投降）

had no choice but to surrender on the spot
【解析】本題考查對(duì)have no choice but to do及短語(yǔ)on the spot的掌握。have no choice but to do意為“除…之外別無(wú)選擇”，注意不要忽略to。on the spot意為“當(dāng)場(chǎng)”。本句時(shí)態(tài)應(yīng)為一般過(guò)去時(shí)，故用had。

3.The customer complained that___________(他剛啟動(dòng)這臺(tái)計(jì)算機(jī)) than it stopped working.

no sooner had he started the computer．
【解析】本題考查對(duì)no sooner…than句型的掌握。no Sooner…than和hardly(scarcely)…when都表示“剛…?就…”，注意其中連詞的區(qū)別。該句型有兩個(gè)特點(diǎn)：一是主句中一般使用過(guò)去完成時(shí)，而從句中一般使用一般過(guò)去時(shí)；二是no sooner或hardly(scarcely)位于句首時(shí)，要求句子采用部分倒裝語(yǔ)序。本句中no sooner位于句首，故句子采用了倒裝語(yǔ)序。

4.The father thought he could ______________(說(shuō)服女兒改變決定)

talk his daughter into changing her mind/persuade his daughter to change her mind
【解析】本題考查對(duì)短語(yǔ)talk sb．into doing sth．或persuade sb．to do sth掌握。兩者都表示“說(shuō)服某人做某事”，但要注意talk sb．into后接動(dòng)名詞，persuade sb．后接不定式。

5.The government was accused____________ (沒(méi)能實(shí)現(xiàn)其改善城市交通狀況的承諾)

of failure to fulfill its promise to improve urban traffic conditions/of failing to fulfill its promise to improve urban traffic conditions ．
【解析】本題考查對(duì)accuse的用法及短語(yǔ)fulfill one’s promise to…的掌握。accuse“指責(zé)、控告”常用于accuse sb．of sth．/doing sth．結(jié)構(gòu)，所以was accused of之后用failure和failing都可以。“實(shí)現(xiàn)…的承諾”用fulfill one’s promise to表示，to后接動(dòng)詞原形。
