　　　3. One day Chuck is on a flight across the Pacific Ocean when suddenly his plane crashes. 一天，查克在飛越太平洋時.他的飛機(jī)突然墜毀了。

　　該句中的“when”表示“正在這時”，相當(dāng)于and just或and at that time. 這時不能用while / as 替換。

　　常見句型：(1) be about to do sth when... (2) be doing sth when... (3) be on the point of doing sth when...

　　【考例】We were swimming in the lake ____ suddenly the storm started.

　　A. when B. while C. until D. before

　　[考查目標(biāo)] "when" 作連詞，表示“正在這時”。

　　[答案與解析] A 意為“我正在湖中游泳，突然暴風(fēng)雨來了。”只有when才能用于這種句型。

　　4. He has to learn how to collect water, hunt for food, and make fire. 他不得不學(xué)會收集淡水.尋找食物，生火什么的。

　　該句中的“how I to collect...”為動詞不定式短語作賓語。例如：We must decide which one to buy. 疑問詞which, what, how, when, where等與小定式構(gòu)成不定式短語。

　　【考例】 I've worked with children before, so I knew what ____ in my new job.

　　A. expected B. to expect C. to be expecting D. expects

　　[考查目標(biāo)] what to do sth 不定式短語作賓語。

　　[答案與解析] B 該句需要填非謂語動詞。排除A、D。句意為“以前我與孩子在一塊兒工作過。因此我知道我的新工作需要什么。”C不表示進(jìn)行，排除C。

　　5. In order to survive, Chuck developed a friendship with an unusual friend — a volleyball he called Wilson. 為了生存下去，查克和一位不尋常的朋友--“排球”建立了友誼，查克叫他威爾森。

　　1. 該句中的"in order to"，意思為“為了，以便”，作目的狀語。在句子中作同的狀語的常見句型有五種結(jié)構(gòu)：to do sth / in order to do sth / so as to do sth / in order that clause / so that clause

　　注意：(1) so as to do sth 不能位于句首。(2) 如果主句與從句的主語一致時，四個結(jié)構(gòu)可以相互轉(zhuǎn)換。(3) 在in order that / so that 引導(dǎo)的從句中，謂語動詞常與can, could, may, might 等情態(tài)動詞連用。

　　【考例】 I'd like to arrive 20 minutes early ____ I can have time for a cup of tea.

　　A. as soon as B. as a result C. in case D. so that

　　[考查目標(biāo)] 目的狀語。

　　[答案與解析]D as soon as “一…就…”;as a result“結(jié)果是”;in case “萬一”;so that“以便，為的是”。句意：“我想提前二十分鐘到以便有時間喝杯茶”。

　　2. 該句子中 volleyball 是作同位語。例如：He advised farmers to choose the best seed-heads, the ones that had the best color.

　　注意：這種同位語(不是同位語從句)與非限制性定語從句的區(qū)別。
