2.silk books

  都是围绕着printing这个话题来让学生们学习和了解这方面的知识。对话中主要运用了询问等方面的用语。及有用的词汇如:come out, keep records, back-to-front等用法。课文中同时也运用了it is believed that clause….the problem was that等同位语从句,动词-ing形式,被动语态, 形容词. 带to不定式”结构的理解。

but later, people developed…

part 1 (paragraph 1) paper was one of the most important inventions in the whole of chinese history.
part 2 paragraphs 2— 5) how paper was invented and develop.
(paragraph 2—3) chinese people used stones, animal bones, metal pots, and pieces of bamboo or wood to keep records.
(paragraph 4) chinese people made a kind of paper as soft and light as silk but much less expensive.
(paragraph 5) the making of paper was well developed; the invention reached other countries.

  the chinese have been making paper for two thousand years. 中国人造纸已经有两千年了。
此句谓语动词用了现在完成时,其结构是have/ has been 现在分词。
i’ve been writing a letter. 我一直在写信。(我仍在写信)
i’ve written a letter. 我写了一封信。(信已写好)
they have been cleaning the classroom. (这项工作仍在进行)比较:
they have cleaned the classroom. 他们把教室打扫过了。(这项工作已经完成)


  it is believed that before writing was developed, people in china used to keep records by putting a number of stones together. 据悉,在有文字以前,中国人常把许多石头放在一起来记事。
1) 本句用的句型是“it is believed that –clause.”
“it is believed that-clause”相当于“people believe that-clause”可译作“人们相信/据信……”。类似的结构有:“it is said/ known/ agreed/ thought that-clause”。例如:
it is believed that there is plenty of oil off our coast. 据信我国沿海有大量的石油。
it is thought that he (has) made much money by selling cigarettes. 人们认为他靠卖香烟赚了很多钱。
at the same time another kind of paper was developed, made form silk. 在这一时期,研制了另一种纸,它是用丝帛制成的。
1)at the same time 作“同时”解。如:
they went their different ways, but arrived at the same time. 他们走的是不同的路线,但却同时到了。
2)made from silk过去分词短语作定语,相当于一个非限制性定语从句,which was made from silk修饰主语another kind of paper.
the problem was that it was too valuable for everyday use. 问题是这些丝织品太贵重,用作日常的书写太昂贵。
(1)句中的“the problem is that…”是个常用句型,在英语语法中,它被称作“主系表” (主语 连系动词 表语)结构。而其中的表语用了一个从句形式(that-clause)。这类句型的主语往往用下列名词question, reason, result, fact, suggestion等。例如:
the question is whether we can finish our work by tomorrow evening. 问题在于我们能否在明晚以前完成我们的工作。
the fact is that he never told me the truth. 事实是,他从未对我讲真话。
the room is too small for us three. 这房间太小,我们三人住不下。
说明:“too…to”也表达同一含意。区别是:for n/ pron.; to in f.。
by the first century the making of paper in some parts of china had been well developed and had become common. 到了公元一世纪,中国有些地区造纸业已十分发达并且变得普遍了。
本句有两个并列谓语,都用了过去完成时态(had been well developed和had become common),表示在过去某一时间之前已经发生的动作。这一过去时间是通过介词by的短语(by the first century)来表示的。又如:
she had not finished her report by yesterday afternoon. 到昨天下午为止,她还没有写完报告。
by the end of last week all the plans had been made. 到上周末为止,所有的计划都订出来了。
they carved a whole page of characters back to front in the wood
“back to front” 是一个合成词,作“反面地”解,在句中作状语,修饰动词carved。
这种合成词是“名词 介词 名词”构成。词与词之间应有连字符连接,如:
side-by-side(肩并肩)、hand-in-hand (手牵手)等
the boy has his sweater on back to front.
he came face to face with death.
although these were much more useful than the metal pots, they were still difficult to read and were very heavy to carry. 和金属锅相比,这些书籍虽然有用得多,但是读起来还是很费劲,拿起来又很重。
1)句中的much为副词,修饰比较级,表示程度,可译为“……得多”。能充当这类程度状语的副词还有far, a lot, even, still, a great deal, a bit, a little等。例如:
houses are much/ far / a lot more expensive these days. 如今房子贵多了。
the chinese farmers are even/ still/ all the / a great deal richer than before. 中国农民比以前更富了。
注意:程度副词every, too等不能和比较级连用。
2)difficult to read和heavy to carry同属于“adj. 带to不定式”结构。
those programmes are usually easy to receive and not difficult to understand. 这些节目通常都很容易接收到,而且也不难听懂。
适应于这种结构的形容词还有:easy, hard, difficult, impossible, comfortable, pleasant, heavy, interesting, pretty等。


辨析every day与everyday

  every day分开写,在句中通常作状语,表示“每天”;
you should read english every day. 你应该每天都读英语。
you should practise your english in everyday life. 你应该在每天的日常生活中去练习英语。


the basket contains a variety of fruits. 这篮子里装有各种水果。
the price includes the tax.这价钱包括税金。
注意:与include 有关的including,included的用法。例如:
we all went to the museum, lily included. 我们去了博物馆,莉莉也去了。
the band played many songs, including some of my favourites.

辨析method 和way

it is english way of living. 这是英国人的生活方式。
we must improve the method of teaching english. 我们必须改进英语教学法。

辨析at the same time与meanwhile

不同点:at the same time意为同时,然而。有两种表示:
1) 两个动作或情况在同一时间发生或存在;
it will cost a lot of money. at the same time, i think we shall need it and it will certainly be useful. 这要花不少钱,但是我们还是需要它,它肯定对我们有用处。
they’ll be here soon. meanwhile let’s have coffee. 他们很快就到,在此期间,我们来喝咖啡吧。

辨析in the beginning, at the beginning







3)与at last“最后”相对,常用at



  the new school term start at / in the beginning of september. 新学期九月初开始。
the shop is at the beginning of the road. 商店就在道路的起点处。
in the beginning, we sued hand tools, later we had machines. 起初,我们用手工工具,后来我们用机器。
she was against the plan at the beginning, but at last she was for it. 她起初反对这个计划,但最后还是同意了。
