1. speak-> speaking
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
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
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。
