1.By the middle of the century, both radio and television had become established means of
transmitting sounds and/or pictures.
译:到二十世纪中叶为止,广播和电视已成为公认的传送声音和/或图象的工具。分析:由于用了时间状语:by the middle of the century,因此要用完成时态。若时间是过去的,用过去完成时;若时间是将来的,用将来完成时。
a.By the end of 2000, we had
learned 50 texts.b.By the end of 2003, we will have
learned 100 texts.

entertainment center.
译:卫星传送信息,电脑储存信息,电视播放信息,把三者结合起来能使每个家庭成为一个教育娱乐中心。分析:虽然句子长,但成分简单。the
combination是主语,will change是谓语。从satellites, which
transmitinformation, computers, which store information, and television, which displays information是介词of的宾语。每个词都包含有一个非限定性
定语从句。
短语:change sth into sth 4.In theory, every person will have

译:同一技术既可助人也可害人,认识到这点很重要。to realize that the same technology that helps us may also harm
us是真正的主语,it是形式主语。that the same technology that helps us may also harm us是
宾语从句;that helps us是
定语从句修饰the same technology.
8.It's the
intelligentapplication of technology that will lead us to success.(*)
译:只有明智地运用技术才能获得成功。这是一个强调句式。正常的句子应是:The
intelligentapplication of technology will lead us to
success.强调句的基本公式:It is/was + 被强调部分 + that(who) + 其余成分。请注意该句式不能强调谓语部分,只能强调主语、宾语、状语。

B.Grammar point: Subjunctive Mood (2)第一讲中介绍过在非真实条件句中的
虚拟语气的主要用法,难点在于句子的时态比真实条件句的时态后退一步。即:现在时→过去时;过去时→
过去完成时;将来时→过去将来时;在今天这讲中将继续将它在一些从句中的用法介绍给大家。
1在
宾语从句中的用法:1>.在suggest, insist, order, demand, request, command等含有希望、建议、命令等语气的宾语从句中。(*)
句型:主语 + should(省略) + 动词原形a. I suggest that we (should) do it at once.
b. I insist that he (should) give up smoking.2>.在wish后的宾语从句中要用虚拟语气,而其时态的用法与非真实条件句一样。(时态后移)
a.I wish I were you.(与现在事实相反的愿望)b.I wish I had
learned more. (与过去事实相反的愿望)
c.I wish I would have another chance. (与将来事实相反的愿望)注意区分:wish + 从句:表示不可能实现的愿望,必须用虚拟语气;而hope + 从句:表示可能实现的愿望,不用虚拟语气。
a.He hopes we'll go there with him.b.He wishes we would go there with him.
3>.在would rather后的从句中. 句型:主语 + would rather + 从句(用一般过去时)I would rather you stayed at home.
2.在
主语从句中的用法。在下列结构的
主语从句中,谓语必须用
虚拟语气。见课本p542。考试的考点时should的省略。
3.在表语从句和
同位语从句中的用法。当
宾语从句中那些使用虚拟语气的动词的名词形式出现在表语从句和同位语从句中时,必须用虚拟语气。即,
suggestion, order, insistence,
demand, request etc.a.My
suggestion is that we (should) try again.(表语从句)
b.My
suggestion that we (should) try again is accepted by them.(同位语从句)4.在
定语从句中的用法。
It is time + that + 主语 + 动词的过去时。It is time that you left.
= It is tome for you to leave.5.在含蓄条件句中的用法。
有时一个假设的情况并不是用条件从句表示,而用其它方式表示,称含蓄条件句。1>.用with, without介词结构代替条件从句。
We might have died you without your help.= We might have died if you hadn't helped us.
2>.用相当于if的其它连词表示虚拟结构。常见的连词有:
otherwise, in that case, on condition that, provided that, but for, etc.
a.I was busy last week,
otherwise I would have come to see you.= I as very busy last week. If I hadn't been busy, I would have come to see you.
b.But for the storm, we should have arrived early.= If we hadn't met the storm, we should have arrived early.
6.在错综时间条件句中的用法。有时非真实条件句中,主句谓语动词所表示的动作和条件句中的谓语动词不是同时发生,这时可按照需要来调整各自的时间。
a. If you had followed the doctor's advice then, you would have be all right now.
主句与从句发生的时间不同,进行调整。b. If you had followed the doctor's advice, you would have been all right then.
主句和从句的动作同时发生。请注意:碰到这种从句要特别注意它的时间状语,必须明确给出时间,否则按同时发生使用。
7.
虚拟语气的倒装与省略。符合下列条件,可以省略if,并进行倒装。
①必须是非真实条件句。②只有当从句中出现were, had, should时,才可省略if,并把这些词放在主语之前。
