英語(yǔ)考試完形填空模擬練習(xí)及答案詳解(一)

　　【解析】close與介詞to連用，意為近的。其他介詞不與close搭配。

　　13.答案D

　　【解析】horror恐懼;trust信任;pleasure愉快;relief(痛苦、憂慮)解除。to one�餾 relief意為讓某人松了一口氣，最符合句意。

　　14.答案B

　　15.答案B

　　【解析】be familiar with為固定搭配，意為熟悉，排除其他選項(xiàng)。

　　16.答案C

　　【解析】本句意為危險(xiǎn)還沒過(guò)去，與前句形成轉(zhuǎn)折關(guān)系。選項(xiàng)中then表順承，therefore表結(jié)果，but表轉(zhuǎn)折，moreover表遞進(jìn)。

　　17.答案A

　　【解析】根據(jù)句意推斷，空格處所填詞應(yīng)與when he had做同位語(yǔ)，故moment符合句意。movement運(yùn)動(dòng)，idea想法，affair事件。

　　18.答案D

　　【解析】following…這個(gè)分詞的邏輯主語(yǔ)應(yīng)為the man，本句意思應(yīng)為，這個(gè)人遵照指令，駕駛飛機(jī)朝機(jī)場(chǎng)飛去。impression意為印象，information消息，inspections視察，instructions指令。

　　19.答案A

　　【解析】as當(dāng)……的時(shí)候，符合句意。unless除非。while當(dāng)……時(shí)候，它引導(dǎo)的從句動(dòng)作時(shí)間比as引導(dǎo)從句動(dòng)作的時(shí)間要長(zhǎng)。So因此，表結(jié)果，不符合句意。

　　20.答案C

　　【解析】本句意為：飛機(jī)沿著跑道滑行了很長(zhǎng)一段距離后，安全地停下來(lái)了。move along是沿著……移動(dòng)的意思。around在……周圍，over在……之上，above在……上方。只有along符合句意。
