1 B had better not do sth 最好不要做什么
意为 当你嘴里在吃东西时最好不要说话
2 c 这是一个瓶子,他是一个空的瓶子.
empty 前应加 an
B had better (not) do sth
B empty是元音开头
1.B
2.第二个B和C怎么都一样.!
应该选B和C因为答案一样了.1
you 'd better not to do sth
不是指整个bottle种类的特指,而是就这一个botle的特指
所以用定冠词a 后面同样的,empty是原音开头,用an当定冠词
1、B (would better (not) do sth.)
2、B (an+元音)
1B had better do sth
had better not do sth固定句型 记住就行了
2C bottle 不是元音音素开头 用a emrty是元音音素开头 用an
1.B 因为You'd better + 动词原型 如要否定 则动词前加not
2.B empty 是原音开头所以用an ，前面的空A 说：这是个瓶子！
