  ☆句型诠释☆

  现在进行时的用法(is / am / are + doing)

  1. 表示现在(说话的瞬间)正在进行或发生的动作。 Look! The monkey is climbing the banana tree.

  2. 表示当前一段时间内的活动或现阶段正在进行的动作。(说话时动作不一定正在进行。) We are preparing for the meeting to be held next Friday now.

  3. 表示说话人现在对主语的行为表示赞叹、惊讶、厌恶等。(常与always, constantly, continually, all the time, forever 等副词连用),表反复的动作。He is always think- ing of others. (表赞许) She is always asking the same question. (表厌恶) You are always changing your mind. (表抱怨)

  4. 表示在最近计划或安排要进行的动作。常用于go, come, leave, start, arrive, return, work, stay 等表移动、方向的动词。He is starting the work in a few minutes. / He is leaving for Beijing tomorrow morning.

  [注意]

  1. 不用进行时的词有:

  (1) 系动词: feel, sound, smell, taste, look, appear, seem, remain, prove 等。

  (2) 表结果的感官动词: see, notice, hear 等。

  (3) 非延续性的动词,此动作开始即是结束:enter, accept, receive等。

  (4) 表心理状态,存在状态,拥有的动词:love, like, hate, care, dislike, respect, prefer, know, understand, forget, remember, believe, want, wish, hope, mind, agree, belong to, depend on, own, have等。

  [比较]

  现在进行时表将来的用法与一般将来时的区别:

  (1) 现在进行时表近期的,事先已经计划安排好的

  -- How are you getting to the airport?

  -- By taxi. Bob is coming with me to the airport.

  (2) will do 和 shall do

  ① 表客观将来。shall用于第一人称,will用于第一、

  二、三人称。I will / shall finish middle school next month.

  ② 表有科学根据的预测。The weather report says it will rain tomorrow.

  ③ 表客观必然。Man will make mistakes.

  (3) be going to

  ① 表现在打算在近期或将来要做某事。I‘m going to finish my homework tonight.

  ② 表根据已有迹象的预测。It‘s so dark outside, I think it‘s going to rain.

  ③ be going to不与come, go连用,而用be coming, be going 形式。Mary is coming here this evening.

  [注意]

  表计划、安排、规定要做的事,用“be + to do”。此外,表示按时刻表运行的动作常用一般现在时表将来。The meeting is to be held at 9:00 a. m. / Our plane leaves at 6:00 a. m. .

  ☆句型归纳☆

  1. You shouldn‘t go rafting unless you know how to swim, and you should always wear a life jacket. 除非你会游泳,而且要一直穿着救生衣,否则就不应该去做漂流运动。

  该句中的unless引导状语从句。例如:One can‘t learn a foreign language well unless he studies hard.

  unless引导的条件状语从句,一般可以与if...not...互换。还要注意unless引导的从句经常可以省略。

  【考例】(200l北京春招)The men will have to wait all day ____ the doctor works faster.

  A. if   B. unless   C. whether   D. that

  [考查目标]状语从句。

  [答案与解析]B 句子意思是“如果医生不快点工作,

  这些人将不得不等一整天。”应该选unless。

  2. Eco-travel is a way to find out what can be done to help animals and plants as well as people. 生态游可以找到既帮助别人.又帮助动植物的途径。

  该句中的as well as是连词,连接两个并列成分。例如: He can speak German as well as French.

  常见的用法:

  1. well是副词,意思是“好,优秀”,as well as是形容词 同级比较结构。

  2. as well as是固定短语,意思是“和”,相当于”not only … but also...”。

  3. as well as连接两个并列成分作主语时,句子的谓语动词应该与前面那个名词或代词的人称或数保持一致。

  4. as well as还可当作复杂介词用,意思是“除了……之外,还有”;相当于”besides,apart from”。

  5. as well,是副词短语,意思是“也”,相当于“too / also”常位于句尾,与too位置相当。

  6. may / might as well do sth 表示“还是……的好”。

  【考例】(NMET 1994) John plays football ____, if not better than David.

  A. as well   B. as well as   C. so well   D. so well as

  [考查目标] as well as连接比较状语从句。

  [答案与解析]B 该句中 if not better than相当于插入语,起干扰作用,如果不予考虑,原句就变成了同级比较结构 ”John plays football as well as David”。
