参考答案及解析　　
参考答案及解析：

　　1.in -> for

　　动词为完成式has been，后面的时间状语应该为一段时间。

　　2. seventh -> seven

　　3. were -> was

　　这句话的主语是one in every seven，表示单数概念，谓语要用单数。

　　4. now -> then

　　根据前一句的时间状语During the early stages of the industrial revolution，此处时间应表示“工业革命之后”，所以应该是from then on.

　　5. the - > /

　　Europe是专有名词，无需加定冠词。

　　6. imported -> exported

　　import意为“进口，输入”，export意为“出口，输出”。根据本句大意，进出口的对象为发达国家生产的抗菌素，显然只能“出口”到贫困国家。此外，根据介词也可以判断，import常与from搭配，export常与to搭配。

　　7. are -> were

　　8. vanished 前加 had

　　这句话的意思是：结核病在已经绝迹的地方又卷土重来。从句谓语动词发生在主句谓语动词came之后，故用过去完成时。

　　9. better->worse

　　10. constantyl -> constant

　　副词constantly并不能作状语表示keep的状态，而是说明宾语number的特征。Keep sth + adj.表示“使...保持..."，故将副词改为形容词，constant作宾语补足语。
