参考答案及解析

参考答案及解析

　　1. speak-> speaking

　　practise后的宾语要用-ing形式。

　　2. Consider -> Considering

　　3. being -> were

　　4. cover -> covering

　　此处的cover用来修饰前面的名词a layer of varnish，可见应该使用非谓语动词形式。另外两者间是主动关系，故使用现在分词。

　　5. from -> avoid是及物动词，后面可以直接跟宾语。

　　6. Taking -> Taken

　　此处的非谓语动词take与主句主语these factors之间是被动关系。

　　7. locating -> located

　　most of them locating in outlying areas这句是独立主格结构，them指代的是residential lots，be located in表示“…坐落在…”，locate要用过去分词。

　　8. between -> balance作动作词时是及物动词，后面不用加介词，意思是“使…平衡”。

　　9. remain → leave?

　　remain：保持、仍然，是一个表示状态的动词，其用法和系动词“be”相似，后面所接成分一般是名词或形容词，作表语。leave是“留下，留给”的意思，是及物动词。leave sth.to sb：把某物留给某人。所以应把remain改成leave。

　　10. informing -> informed

　　本题中one指的是人，one与inform之间是被动关系，informed作的是宾语补足语。

　　Keep + sth /sb + a / v-ing / v-ed，宾语补足语是用现在分词还是过去分词取决于它与sth / sb之间是被动还是主动关系。
