中考英語考點分析 肯定句變否定句

　　7. He always gets there on time.

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

　　正：He never gets there on time.

　　析：He doesn’t always get there on time意為“他并非老是準(zhǔn)時到那兒”，是部分否定，習(xí)慣上把句中的副詞改為相應(yīng)的表示否定的副詞即可。如：

　　It often rains here. It seldom rains here.

　　8. Be here early tomorrow.

　　誤：Be not here early tomorrow.

　　正：Don’t be here early tomorrow.

　　析：祈使句的否定，一般在謂語動詞前加do not的縮寫don’t。

　　9. You had better come.

　　誤：You didn’t have better come.

　　正：You had better not come.

　　析：had better相當(dāng)于一情態(tài)動詞，不可分割，因此not應(yīng)放在其后。would rather也是如此。

　　10. Both Tom and Xiao Ping went to school.

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

　　正：Neither Tom nor Xiao Ping went to school.

　　析：一個句子中如果有不定代詞both，all, every改為否定式時，要把這些不定代詞改為相應(yīng)的表示否定的代詞。
