1. 【问】My leather tennis shoes are worn out. I need another pair. 第一句中的are worn out 是强调被动吗?第二句中的pair可以用one替换吗?
【答】wear out 意为"穿坏;用旧",后面要接宾语。如果表示"某物被穿坏或用旧"则用be worn out。虽然该结构在形式上与被动语态一致,但它只强调状态,而不强调被动。
第二句中的pair 指的是a pair of leather tennis shoes, 故不能用one代替pair。
2.【问】Even though they're a little expensive, I'll take them. 句中even though的用法与even if一样吗?
【答】even though =even if, 用于引导让步状语从句,意为"尽管;即使;纵然"。它们引导让步状语从句时,若主句是一般将来时,从句通常用一般现在时代替一般将来时。
但二者又有区别:even though引导的从句的内容往往是事实;而even if引导的从句可能是假定性的。试比较:
Even though he knows it, he'll not let out the secret.(他知道这个秘密)
Even if he knows it, he'll not let out the secret.(不确定他是否知道这个秘密)
3.【问】The camera cost so much that I didn't buy one. 句中so可以换成such吗?
【答】不可以。so...that...与such...that...都可作"如此......以致于......"解,但二者所惯用的句型不同。so 通常用于以下几种句型:
1)so + adj. / adv. + that从句。如:
The book is so expensive that I can't afford it.
2)so + many / much / few / little + n. + that 从句。如:
He has so few friends that he is lonely.
3)so + adj. + a(an) + n. + that从句。如:
She is so clever a girl that we all like her.
而such 通常用于句型:such + (a/an) + adj. + n. + that 从句。如:
He is such a young boy that he can't go to school.
