[析] so與such的用法可以分為四種情況，①用于單數(shù)可數(shù)名詞之前，其格式是such+不定冠詞+形容詞+單數(shù)可數(shù)名詞，如：It is such a beautiful book that every child likes it. 也可以用so, 其格式是so+形容詞+不定冠詞+單數(shù)可數(shù)名詞，如：It was so beautiful a book that every child likes it. ②在不可數(shù)名詞前或可數(shù)名詞復數(shù)前這時只能用such, 如：It is such good weather that we want to swim. 又如：They are such good students that they can pass the exam easily. ③在few, little, much, many 這4個字前只能用so而不能用such, 如：I have so much money that I can buy everything I want. ④當that前只有形容詞或副詞時，這時只能用so, 如：She is so beautiful that every one likes her. He ran so fast that I couldn't keep up with him.
[誤] He got up earlier this morning so as to that he could catch the first bus.
[正] He got up earlier this morning so as to catch the first bus.
[正] He got up so earlier that he could catch the first bus.
[析] so…that與so that的用法有相同之處，那就是其后接從句，而so as to 其后要接不定式，即動詞原形。這樣的詞組還有：in order to.
[誤] I want to buy same stamp that you have.
[正] I want to buy the same stamp as you have.
[析] the same…as (that)這是個固定用法，在same前的定冠詞是不能少的。而the same…that意為"我要的就是那一個".而the same…as為"要的是和……一樣的東西".
[誤] Before I do not give you the answer, I'll ask you some questions.
[正] Before I give you the answer, I'll ask you some questions.
[析] 這種錯誤是由于受中文的影響。在中文中可以講"我沒給你答案前".而英文用了before就不要再用否定句了。
