本单元语法复习:
现在进行时;
used to句型;
被动语态;
现在完成时;
情态动词。
现在进行时
(1)含义:表示正在发生或进行的动作。
(2)基本结构:
主语 + be + 现在分词(be 的形式随主语的变化而变化)
(3)基本用法:
①表示现在正在进行的动作。特征:常常与now或具体的时间连用,有时句中会有感官动词来提示,或通过上下文来暗示。
②表示现阶段一直进行的动作。这类动词常常是延续性动词。常于at present, this week, these days等连用。
③表示主语的特征、性格、能力等
现在完成时
(1)含义:表示过去发生的动作对现在还有影响。
(2)基本结构:主语 + have / has + 过去分词
(3)基本用法:
①表示过去发生的动作,但强调对现在产生影响。特征:不能与表示具体的时间状语连用。
②表示过去发生的动作或存在的状态一直延续到现在,还可能继续下去。常常与since, for, in the past + 时间名词,in the last +时间名词等时间状语连用,而且谓语动词要求是延续性动词。
③表示一种“经历或体验”,即可以表示经历过也可以是从来都没有经历过。
被动语态
归纳如下(三种红色要求熟练掌握,其余为了解)
(1)一般现在时是被动语态:am / is / are + 过去分词
(2)现在完成时的被动式:
have / has + been + 过去分词
(3)现在进行时的被动式:
am/ is/ are + being + 过去分词
(4)一般过去时的被动式:was / were + 过去分词
(5)过去进行时的被动式:
was / were + being + 过去分词
(6)过去完成时的被动式:had + been + 过去分词
(7)一般将来时的被动式:
will / be going to be+ 过去分词
(8)含有情态动词的被动式:
情态动词+be +动词的过去分词。
情态动词
情态动词表示说话人对某一动作或状态的态度,如认为“可能”、“应当”、“必要”等。情态动词本身有一定的意义,但不能单独作谓语,也没有人称和数的变化。后面一般跟动词原形。
used to 结构
used to意为“过去常常做某事”,指的是过去的习惯性动作,目的在于与现在形成对照。used to是个情态动词,其中的to是不定式符号,后面跟动词原形。在美式英语中。它的疑问式是:Did +主语+use to do sth.?否定式是:主语+didn't use..。在英式英语中,它的疑问式应当是:Used +主语+to sth.?否定式应当是used not to或use(d)n't to。
He used to stay up late. 他过去常熬到很晚。
used to 结构
used to意为“过去常常做某事”,指的是过去的习惯性动作,目的在于与现在形成对照。used to是个情态动词,其中的to是不定式符号,后面跟动词原形。
在美式英语中(掌握)
它的疑问式是:Did +主语+use to do sth.
否定式是:主语+didn't use.
在英式英语中(了解)
它的疑问式应当是:Used +主语+to sth.
否定式应当是used not to.
1. harmful 形容词,意为“有害的”。常构成短语
be harmful to “对……有害的”。
Staying up often is harmful to your health. 经常熬夜对你的健康有害。
【拓展】
harm 名词,意为“害处”。常用构成短语
do harm to “对……有害”,相当于be harmful to.
Too much smoking does harm to his health. = Too much smoking is harmful to his health. 吸烟过多对他的健康有害。
Language points
2. 辨析:join, join in 和take part in
to
join 加入组织,团体,党派等,有作为其中的一个成员的含义;
后面也可以加表示人的名词,表示和某人一起参加某活动
join in 加入一种具体活动。
take aprt in 指参加会议或群众性活动等,着重说明句子主语参加该项活动并在活动中发挥作用。
例如:
Will you join us in the discussion
你参加我们的讨论吗?
She joined the Young Pioneers.
她加入了少先队。
Why didn't you join in the talk last night
昨晚你为什么没参加座谈?
Did you take part in the sports meet
你参加运动会了吗?
3. afford的用法
⑴ afford是动词,意为“买得起,担负得起”,通常与can, could, be able to连用,多用于否定句中。
They couldn’t afford $50 for a ticket. 他们拿不出50美元买一张票。
⑵ afford后面常跟带to的动词不定式。
We can’t afford to go abroad this summer. 今年夏天我们没有足够的钱出国。
4. Not only… but also…意为 “不但…而且…”
遵循一下三个原则
(a)并列连词,连接两个并列成分,其中also
可以省略。
(b) 主谓一致原则:not only…but also..连接两个
主语时,谓语动词在人称和数上要与but also
的主语保持一致。
(c) 倒装原则:not only…but also…连接两个并列分句时, not only 置于句首,表示强调,其引导的句子要用部分倒装,即将谓语动词的一部分(情态动词,助动词等)放在句子的前面,而but also后的句子用正常语序。
Not only he but also I am interested in pop music.
Not only do I feel good about helping people, but also I get to spend time doing what I love to do.
⑴ need doing=need to be done "需要被…"现在
分词doing表被动“需要被做”,相当于need
to be done。
My watch needs repairing. =My watch needs
to be repaired.我的表需要修了。
⑵ need后加不定式,证明need为实义动词,而
非情态动词,这时need有人称和数的变化。
He needs to get up early. 他需要早起。
5. 辨析:need to be done; need doing与need to do
七、书面表达
保护人类共同的家园----地球是每个人的责任和义务。我们在生活中的点滴小事上也能作出自己的贡献。根据表格内容,谈一谈你曾经为保护环境做过哪些努力,将来还打算如何去做。
