中考英语考点分析 肯定句变否定句

　　7. He always gets there on time.

　　误：He doesn’t always get there on time.

　　正：He never gets there on time.

　　析：He doesn’t always get there on time意为“他并非老是准时到那儿”，是部分否定，习惯上把句中的副词改为相应的表示否定的副词即可。如：

　　It often rains here. It seldom rains here.

　　8. Be here early tomorrow.

　　误：Be not here early tomorrow.

　　正：Don’t be here early tomorrow.

　　析：祈使句的否定，一般在谓语动词前加do not的缩写don’t。

　　9. You had better come.

　　误：You didn’t have better come.

　　正：You had better not come.

　　析：had better相当于一情态动词，不可分割，因此not应放在其后。would rather也是如此。

　　10. Both Tom and Xiao Ping went to school.

　　误：Both Tom and Xiao Ping didn’t go to school.

　　正：Neither Tom nor Xiao Ping went to school.

　　析：一个句子中如果有不定代词both，all, every改为否定式时，要把这些不定代词改为相应的表示否定的代词。
