too…to 句型的用法
該結(jié)構(gòu)的基本形式為“too+形容詞或副詞+to+動(dòng)詞原形”,其意為“太…以至于不能…”：
He is too tired to go any further.他太累了,不能再往前走了.
He is too shy to speak to her.他太害羞,不敢同她講話.
It’s too cheap to be good.這東西太便宜,好不了(即便宜無(wú)好貨).
He is too young to know right from wrong.他太小,還分不清是非.
有時(shí)不定式前可以帶有一個(gè)由介詞for引出的邏輯主語(yǔ)：
The box is too heavy for me to carry.這個(gè)箱子太重,我提不起.
另外,該句型有時(shí)可與so [such]…that結(jié)構(gòu)轉(zhuǎn)換：
The box is too heavy for me to carry.
→The box is so heavy that I can’t carry it.
→It is such a heavy box that I can’t carry it.
