    該句中的unless引導(dǎo)狀語從句。例如：One can't learn a foreign language well unless he studies hard.
    unless引導(dǎo)的條件狀語從句，一般可以與if...not...互換。還要注意unless引導(dǎo)的從句經(jīng)?？梢允÷?。

    該句中的as well as是連詞，連接兩個并列成分。例如: He can speak German as well as French.
    常見的用法:
    1. well是副詞，意思是“好，優(yōu)秀”，as well as是形容詞 同級比較結(jié)構(gòu)。
    2. as well as是固定短語，意思是“和”，相當(dāng)于"not only … but also..."。
    3. as well as連接兩個并列成分作主語時，句子的謂語動詞應(yīng)該與前面那個名詞或代詞的人稱或數(shù)保持一致。
    4. as well as還可當(dāng)作復(fù)雜介詞用，意思是“除了……之外，還有”;相當(dāng)于"besides，apart from"。

    6. may / might as well do sth 表示“還是……的好”。

    A. as well B. as well as C. so well D. so well as
    [考查目標] as well as連接比較狀語從句。
    [答案與解析]B 該句中 if not better than相當(dāng)于插入語，起干擾作用，如果不予考慮，原句就變成了同級比較結(jié)構(gòu) "John plays football as well as David"。
    3. Before she could move，she heard a loud noise. 她還沒有來得及動彈，就聽見很響的聲音。
    However, before she could think twice, the water was upon her. 但還沒有回過身來，洪水便逼近了她。

    【考例】(2005廣東) The American Civil War lasted four years the North won in the end.

    情態(tài)動詞may，might，most.can，could常用來表示推測。may，might，must多用在肯定句中，can，could多用在否定句和疑問句中。may，might，must，can，could后接動詞原形表示對現(xiàn)在的推測;may，might，must，can，could后接have done。表示對過去的推測。例如：
    You may be a professor. / She must have met a fairy.
    【考例】(2005遼寧)This cake is very sweet. You ____ a lot of sugar in it.
    A. should put B. could have put
    C. might put D. must have put
    [考查目標] 情態(tài)動詞表示推測。
    [答案與解析] D 前文說蛋糕很甜，由此可知一定是糖
    放多了。對于過去的動作的推測應(yīng)使用have done的
    結(jié)構(gòu)，所以應(yīng)在B、D之間做選擇，又因為could have
    done表示本可以做而沒有做，所以選擇D。
    5. ... she heard a loud noise，which grew to a terrible roar. ……她聽見了很響的聲音，接著就變成了可怕的隆隆轟鳴聲。
    該句中的which引導(dǎo)非限制性定語從句。例如：He bought some reference books, which were all about science. 他買了許多的參考資料.都是有關(guān)理科的。
    which 作為關(guān)系代詞.既可以引導(dǎo)限制性定語從句，也可以引導(dǎo)非限制性定語從句。例如：The train which left for Beijing pulled in on time. 前往北京的火車按時進站了。His dog, which was now very old, became ill and died.他的狗，現(xiàn)在老了，生病死了。
    【考例】(2005浙江) Jim passed the driving test, ____ surprised everybody in the office.
