step 1 疑難透析
1. what had he been doing before the earthquake ?
過(guò)去完成進(jìn)行時(shí)表示在過(guò)去一個(gè)時(shí)間點(diǎn)以前一直進(jìn)行的動(dòng)作; 而現(xiàn)在完成進(jìn)行時(shí)則表示從過(guò)去一個(gè)時(shí)間點(diǎn)開(kāi)始一直進(jìn)行的動(dòng)作。例如:
i had been doing my homework before you came .
i have been doing my homework since i came back home .
注意 完成進(jìn)行時(shí)都是強(qiáng)調(diào)動(dòng)作的延續(xù), 故其中的動(dòng)詞必須是延續(xù)性的。
考查方向 現(xiàn)在與過(guò)去進(jìn)行完成時(shí)的辨異。
【典型考題】 北京高考
three months went by before she knew it . 她還沒(méi)有意識(shí)到三個(gè)月就過(guò)去了。
now that she is out of a job , lucy __________ going back to school , but she hasn’t decided yet .
a. had considered b. has been considering
c. considered d. is going to consider
【解析】由 she hasn’t decided yet 可知, lucy 還在考慮這件事情, 故用現(xiàn)在完成進(jìn)行時(shí), 表示動(dòng)作還在繼續(xù)。
【答案】b。
2. before she could move , she heard a loud noise .
before she could think twice , the water was upon her .
本句中，before 意為“還未來(lái)得及…就…”， 例如：
the telephone was hung up before i could answer it .
我還未來(lái)得及接電話(huà), 電話(huà)就掛斷了。
before 還可以表示“… 之后才…”, 例如:
he almost knocked me down before he saw me .他幾乎把我撞倒才看到我。
before 還可用于 it was not long before …結(jié)構(gòu), 表示“不久以后”。在此句式中, it 表示時(shí)間, before 引起時(shí)間狀語(yǔ)從句。若從句時(shí)態(tài)為將來(lái)時(shí), 應(yīng)用現(xiàn)在時(shí)表示。例如:
it was not long before the whole country rose up and drove the enemy out of their homeland . 不久以后, 全國(guó)人民奮起反抗, 把敵人趕出了他們的國(guó)土。
注意 before 用法很多, 在平時(shí)的學(xué)習(xí)中應(yīng)特別注意。它既可用作連詞又可用作介詞, 應(yīng)注意不同詞性需要不同形式。
考查方向 before 與其他連詞的意義辨析以及詞義。
【典型考題】 北京高考
he made a mistake , but then he corrected the situation ___________ it got worse .
a. until b. when c. before d. as
【解析】根據(jù)句意“在形勢(shì)變得糟糕之前糾正錯(cuò)誤”可知, 答案應(yīng)為 before 。
【答案】c。
3. who， whom ， that ，which 或 whose 引起的定語(yǔ)從句以及關(guān)系詞與普通連詞 and，but 等的用法區(qū)別。
who， whom， that， which 或 whose 為引起定語(yǔ)從句的關(guān)系代詞，該使用哪一個(gè)由其在句中做的成分來(lái)決定：who， whom ，that ，which 在從句中作主語(yǔ)、賓語(yǔ)，而whose 在從句中作定語(yǔ)。
定語(yǔ)從句應(yīng)為句子的一部分，故從句的前面不需要 and， but，so，or 等連詞。而句中若有了這些連詞，則不使用定語(yǔ)從句。這也就是何時(shí)使用關(guān)系詞，何時(shí)使用普通代詞的問(wèn)題。例如：
he has three sons，and all of them are doctors .
或: he has three sons , all of whom are doctors .
考查方向 是選擇關(guān)系詞還是選擇普通代詞, 也就是選擇含有定語(yǔ)從句的復(fù)合句還是并列句。
【典型考題】 遼寧高考
the factory produces half a million pairs of shoes every year, 80% __________ are sold abroad.
a. of which b. which of c. of them d. of that
【解析】80% 的前面沒(méi)有連詞, 故應(yīng)用定語(yǔ)從句形式, 排除 c 項(xiàng); 而 that 不能直接充當(dāng)介詞的賓語(yǔ), d 項(xiàng)錯(cuò)誤; 用 of which 表示從屬關(guān)系“其中的”, 引導(dǎo)定語(yǔ)從句。
【答案】a。
4. 分詞做狀語(yǔ)
分詞在句中做狀語(yǔ), 是一個(gè)重要的語(yǔ)法項(xiàng)目, 一定要把握。
若分詞在句中做狀語(yǔ), 則由句子的主語(yǔ)來(lái)決定其形式。若主語(yǔ)與分詞之間為主動(dòng)關(guān)系, 則用現(xiàn)在分詞; 為被動(dòng)形式, 則用過(guò)去分詞; 沒(méi)有主動(dòng)或被動(dòng)關(guān)系, 則用狀語(yǔ)從句或獨(dú)立主格作狀語(yǔ)。例如:
a storm broke out suddenly , sweeping away everything .
（a storm 與sweep away 之間為主動(dòng)關(guān)系 ）
given more time , i will do it better . （i 與give 之間為被動(dòng)關(guān)系）
it being a hot day , they went swimming . （獨(dú)立主格）
辨析 分詞做狀語(yǔ)與并列謂語(yǔ)動(dòng)詞
若幾個(gè)動(dòng)詞之間沒(méi)有主次之分, 只有時(shí)間先后, 則用作并列謂語(yǔ), 表示連續(xù)的動(dòng)作, 最后兩個(gè)動(dòng)作之間加連詞; 若動(dòng)詞之間有主次之分, 則次要?jiǎng)釉~用作分詞作狀語(yǔ), 主要?jiǎng)釉~用作謂語(yǔ), 且分詞前不能加連詞。
考查方向 在具體的語(yǔ)境中, 過(guò)去分詞和現(xiàn)在分詞的選擇。
【典型考題】 廣東高考
____________ the program, they have to stay there for another two weeks .
a. not completing b. not completed
c. not having completed d. having not completed
【解析】現(xiàn)在分詞的完成式表示動(dòng)作發(fā)生在謂語(yǔ)動(dòng)詞以前, 其否定形式要在分詞的前面加not 。
【答案】c。

1. before she could move , she heard a great noise, which grew to a terrible roar.她還沒(méi)來(lái)得及跑，就聽(tīng)到一個(gè)巨大的聲音逐漸變成可怕的轟鳴聲。

①跟動(dòng)詞原形表示對(duì)現(xiàn)在事情的猜測(cè)；
②跟be doing表示對(duì)正在發(fā)生事情的猜測(cè)；3）跟have done表示對(duì)已經(jīng)發(fā)生的事情的猜測(cè)。
