　　单元难点疑点思路明晰

　　1 . Can\'t they be mended ? 难道它们 ( 鞋子 ) 不能修吗 ?

　　以否定形式提问的疑问句叫否定疑问句。这种疑问句包括一般疑问句和特殊疑问句的结构。句中的 not 可以和有关的 be、have 以及助动词、情态动词结合，构成 - n\'t 形式放在主语之前。

　　一般否定疑问句往往表示怀疑、惊讶、责备等意义，实质上它具有强烈的“肯定”意味。如上述的例句，问话者的心中是相信它肯定能修。又如：

　　Can\'t you ( really ) ride a bicycle ?

　　Haven\'t you forgotten something ? 难道你们没忘记什么吗 ?

　　2 . They were so pleased to see each other that they forgot everything else . 他们彼此见面，格外高兴，把所有的事都忘了。

　　①so…that 意思是“如此……以致。”so 修饰它后面的形容词或副词，that 后面通常是表示结果的状语从句。又如：

　　It was so dark that he couldn\'t see anything . ( so 后接形容词 )

　　The teacher spoke so fast that I couldn\'t follow him . ( so 后接副词 )

　　②在这种意义的结构中，如果结果状语从句是否定式，可换成“too … to”的结构。如果结果状语从句是肯定形式，可以换成“…enough to…”的结构。如：

　　He was so weak that he could not walk . = He was too weak to walk .

　　③注意：so … that 与 so that 有区别。so that 引导目的状语从句，经常和 may , can , could , should , will , would 等情态动词连用。是“以便；为的是”之意，如：

　　Speak clearly so that we may understand you .

　　3 . My shoes are worn out . 我的鞋穿破了。

　　( 1 ) worn out 是过去分词短语，在句中作表语。

　　( 2 ) wear out “穿破；磨破；用坏”。例如：

　　Usually , children wear out their toys very quickly .

　　That machine was worn out last year .

　　Who wore out that bike ?

　　4 . I\'m looking for a pair of black shoes . 我想买一双黑色的皮鞋。

　　looking for 在此表达购物人在购物时“寻找”所购物品的状态。

　　5 . What size do you want ? Size eight
