Question

Science and technology are developing ______ quickly that some new electronic products are out-of-date within several months.

A．very

B．so

C．such

D．too

Answer 1

B

試題分析：考察固定句式。固定句式so…that…如此…以至于…；so后面要接形容詞或者副詞。Sucn…that…中的such后面要接名詞，或者名詞短語(yǔ)；AC兩項(xiàng)后面不能接that從句。句意：科技進(jìn)步得如此之快，以至于一些新的電子產(chǎn)品幾個(gè)月就過(guò)時(shí)了。故B正確。
點(diǎn)評(píng)：常用的結(jié)構(gòu)一定要掌握。拓展：和“that”連用時(shí)，so與such意思基本一樣，但句型結(jié)構(gòu)不同�！皊o…that…”句型結(jié)構(gòu)為：so + adj. （adv.） +that…；so + adj. +a（an）+單數(shù)n. +that…；so +many（few）+復(fù)數(shù)n. +that…；so +much（little）+不可數(shù)n. +that…；“such…that…”句型結(jié)構(gòu)為：such + a （an）+adj. +單數(shù)n. +that…；such + adj. +復(fù)數(shù)n. +that…；such +adj. +不可數(shù)n. +that…
