1. Cneedn’t have done sth.表示做了不必做的事，此句意为：“你真不必写这么长的文章，老师告诉我们只写200个词，可你写了300个词。”

2. AB、C选项之所以错，主要是由于long的位置不对，应为：B. Being long used…;C Having long been used…。句子前半部分是状语，故D也不对。由此可见A是惟一正确的选择。

3. Cother than 的意思相当于except，常用在否定词之后，如nobody other than…，nothing other than等。本句中与no在一起连用，意为“只有在英国……”。it has been said是插入语。

4. Bas是关系代词，引导非限定性定语从句， 其先行词是measures，相当于…as the measures which are taken by the government…，其他几个词都是连词，不能引导定语从句。

5. A句中的第一个空白处需要一个引导名词性从句的关系代词，在从句中做write 的宾语;第二个空白处要填一个修饰way的定语从句的关系代词，因此只能选A。注意: 先行词是way, 引导定语从句的关系代词一定不能用how, 可以用in which, 可以用that, 也可以省略不用。
