英语选择题_______you eat the correct foods____be able to keep fit

6个回答

  • _______you eat the correct foods____be able to keep fit and stay healthy

    A Only if;will you B Only if;you will C Unless;will you D Unless;you will

    答:A

    译:只有正确饮食,才可能保持健康.

    析:本题考查部分倒装.Only +状语,要引主句谓语的部分倒装(将you will be able to ...中第一个助动词will提到主语you的前面),排除BDC

    扩展:这状语有三种形式:

    1.副词:Only then did he realized that he was wrong.

    2.介短:Only in this way can you learn English well.

    3.从句,常见的是when-时间状语从句:Only when the war was over in 1949 was he able to return home.

    这里if-从句表示一条件,只有在这个条件下,你才可以保持身材,保持健康.
