两个考点
第一,感叹句,判定what 和 how
how + adj.+主语+谓语
what + n.+主语+谓语
useful invention (有用的发明)是一个词组,从语句和语义判断,都是名词词组,应该选择what.(注意:不能单纯因useful是形容词就想到用how)
第二,useful是否为元音开头
useful的音标为[`ju:sful],第一音标不是元音,所以用a.
综上,判断应该选A

A ,因为useful 不是元音开头,invention是名词则用 what
如果 为形容词 例如 how beautiful she is!

B 感叹句且invention可数

选b感叹句,useful是元音音素u开头的要用an,whatan作宾语

C useful以元音字母开头 用an how + adj+主语+谓语

感叹句
a

A
感叹句形式有两类:what 和 how how + adj. +主语+谓语 what + n. +主语+谓语
其中的useful的音标为 [ˈjusf(ə)l],不是以元音开头的,用an的条件是名词以 A E I O U 开头,然后是其音标也是以元音字母开头

选A。how在感叹句中是用来修饰形容词,而what感叹句中是用来修饰名词,此句子useful修饰invention,而useful中的u的英标为/ju;/,不为辅音字母,故选A。
愿采纳
