一.?词语辨析?
1. personal / private / individual
【解释】
personal 指属于或关于某人或某些特定的人,以区别于其他人。
private 指属于私人所有或具有私营性质,以区别于集体或公共的,有时含不公开的意味。

3). We traveled together, but each _________ bought his own ticket.
Keys: 1). personal 2). private 3). individual
2. after all/above all/at all/in all
【解释】
after all意为“毕竟”“尽管”“到底”“究竟”;
above all 意为“最重要的是”“尤其是”;
at all一般用在否定句中,用以加强否定语气。at all用在疑问句、条件句中,起强调作用,意为“真的”“确实”“竟然”等。另外,not at all用来表示“不用谢”;
in all表示“总共”“总计”。

3. type / kind /sort
【解释】
1)kind系普通用语,其含义较模糊,它所指的种类可用任何标准区分,但着重以事物的自然属性和内在性质为标准来区分。
2)type常和换用kind,但在表示动植物的种类,以及牌类游戏时,不能用type代替
3)sort也为普通用语,比kind更口语化,其概念同kind一样很不严密,两者常可互换, 但sort常掺杂说话人的主观色彩,带有轻蔑与贬低的含义。如:
We talked of all sorts of subjects.我们谈了各种话题。
These sorts of people are ready to eat anywhere.这种人总是走到哪里吃到哪里。

【解释】
deal with和do with二者可译为“处理”,但在特殊疑问句中, do with与what配合使用,而deal with与how配合使用。
