　　第十八篇答案+解說：

　　1.【答案】A

　　【解析】本句意為盡管乘客們都已經(jīng)系好安全帶，他們還是被突然向前拋去。Although盡管，引導(dǎo)讓步狀語從句，符合句意。while當……時候;therefore因此;then接著、然后。

　　2.【答案】B

　　【解析】根據(jù)上題注釋，這里選擇throw扔、拋，最為合適。shift轉(zhuǎn)移;move移動。

　　3.【答案】D

　　【解析】show展示、表明;present呈現(xiàn)、陳述，及物動詞;expose暴露。appear出現(xiàn)，符合句意。

　　4.【答案】C

　　【解析】well健康的;still靜止的;calm鎮(zhèn)靜的;quiet安靜的。前句說她看上去臉色蒼白，后半句進行轉(zhuǎn)折，calm最符合句意。

　　5.【答案】C

　　【解析】inform通知、告訴，符合句意。inquire詢問;insure保險、投保，常與aginst連用;instruct指示、指令。

　　6.【答案】D

　　【解析】fallen摔倒、跌落;fail失敗;fade衰弱(視力、聽覺、記憶);faint昏迷、暈倒。D項最符合句意。

　　7.【答案】B

　　【解析】at best最多、至多;at least至少;at length詳細地;at first開始、最先。at least最符合句意。

　　8.【答案】A

　　【解析】hesitation猶豫;surprise吃驚;doubt疑問;delay延遲。hesitation最符合句意。

　　9.【答案】B

　　【解析】本句意為把飛行員挪到一邊。aside意為一邊、旁邊，符合句意。back向后;about到處;move off指車輛啟程。

　　10.【答案】C

　　【解析】本句意為：這個人坐到飛行員的座位上，認真聽發(fā)自下面機場通過無線電發(fā)出的緊急指令。patient耐心的;anxious焦急的;nervous緊張的，都不符合句意。只urgent合適。

　　11.【答案】D

　　【解析】beneath和under為介詞，后面必需接名詞。down向下地，副詞。below在下方地，副詞，符合句意。

　　12.【答案】A

　　【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

　　【解析】surround包圍;circle盤旋;observe觀察;view認為。此處選擇circle，最符合句意。

　　15.【答案】B

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

　　16.【答案】C

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

　　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，故moment符合句意。movement運動，idea想法，affair事件。

　　18.【答案】D

　　【解析】following…這個分詞的邏輯主語應(yīng)為the man，本句意思應(yīng)為，這個人遵照指令，駕駛飛機朝機場飛去。impression意為印象，information消息，inspections視察，instructions指令。

　　19.【答案】A

　　【解析】as當……的時候，符合句意。unless除非。while當……時候，它引導(dǎo)的從句動作時間比as引導(dǎo)從句動作的時間要長。So因此，表結(jié)果，不符合句意。

　　20.【答案】C　　【解析】本句意為：飛機沿著跑道滑行了很長一段距離后，安全地停下來了。move along是沿著……移動的意思。around在……周圍，over在……之上，above在……上方。只有along符合句意。
