??????［误］Make yourself home.［正］Make yourself at home.［析］这是英语中的习惯用法，意为“像在家里一样”。这样的用法还有：enjoy oneself 玩得开心make yourself at home 像在家中一样help yourself to something 自己拿某物lost oneself 迷路seat oneself 就坐dress oneself 穿衣???［误］—Who's this speaking.—That's Mary.［正］—Who's that speaking.—This is Mary.［析］在电话用语中，this指讲话人自己，而that指对方。???［误］The days in summer are longer than this in winter.［正］The days in summer are longer than those in winter.［析］在比较句中往往为了避免重复，可以用that或those取代前面提到的事物，如是单数时用that,复数时用those，如：The weather in Beijing is hotter than that in Chang Chun.????［误］It is so a good book that everyone likes to read.［正］It is such a good book that everyone likes to read.［正］It is so good a book that everyone likes to read.［析］在可数名词单数时可用so+形容词+不定冠词+名词+that从句，也可用such+不定冠词+形容词+that从句。在不可数名词或可数名词复数时，只用such, 如：It is such good weather that I want to go swimming. They are such good books that I want to buy them all.在many, much, few, little这4个词前仅能用so,如：She has so much money that she can buy everything she wants.而在so与that之间仅存形容词时，则不能用such,如:She is so sweet that everyone likes her.
