二、词义辨析
1.too much与 much too大不相同
too much: 中心词在much, 意为 “太多,过分”, 在句中作定语,修辞不可数名词,也可用作状语, 修辞动词, 还可用作主语、表语等.
例如:
Sorry that I’ve put you too much trouble.
很抱歉给你添了太多麻烦.
He drank too much at the dinner party.
餐会上他喝的太多了.
It really is too much of your father to bring guests home to dinner without letting me know in advance.
你父亲实在太过分了,事先不告诉我一声就带客人到家里来吃饭.
Too much has been talked about the topic.
关于这个话题已经谈过太多了.
much too: 中心词在too, 意思是 “极其,非常”, 修辞形容词或副词,表示程度.
例如:
The problem is much too difficult for me.
这道题对我来说太难了.
His condition is much too bad, and needs a further examination.
他的身体状况非常糟糕, 需要作进一步检查.
2.辨析:though, although, even though, as though
although 和 though:“虽然,尽管”的意思。都可用作连词引导让步状语从句,两者可互换。
例如:
They are
generous although/ though they are poor.
他们尽管穷,却十分慷慨。
though 引导让步状语从句时和as一样,表语可以提前;此外,though 还可以用作副词。
例如:
Hardworking though/as he was, there was never enough money to pay the bills.
他虽然工作很辛苦,但却一直是入不敷出。
It’s a hard work; I enjoy it, though.
这是件苦差,不过我倒很乐意干。(though 用作副词)。
even though:和even if同义, “尽管,即使,纵然”,用作连词引导让步状语从句,语气比though, although更强。
例如:
She won’t leave the television set, even though/ even if her husband is
waiting for his supper.
即使她丈夫等着她吃晚饭,她也不愿意离开电视机。
as though:和as if 同义,“好像,仿佛”,用作连词,引导表语从句和方式状语从句。
例如:
He sounds as though/ as if he’s got s sore throat.
他的声音听起来好像是喉咙痛。
He opened his lips as though/ as if he would say something.
他张开嘴,好像要说什么。
三、重点句型
1.Now that we are developing new technology at such a high pace, the true
challenge is to find new ways of using it. 既然我们正高速地发展新技术, 真正的挑战在于寻找新的使用途径.
now that是固定短语, 意为 “既然; 由于”, 引出原因状语从句, that可省略.
如:
Now (that) he is well again, he can go on with his English study.
2.Maybe it is time for the rest of society to accept me as I am and get used to the fact that while I may not be able to walk, there are many other great things I can do. 或许到了社会上的其他人承认我的时候了, 到了他们接受这样一事实的时候: 虽然我不会走路, 但仍有很多事情我可以做.
