　　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：
　　如face-to-face（面对面）、back-to-back（背面背）
　　　side-by-side（肩并肩）、hand-in-hand (手牵手)等
　　这种合成词在句中多作定语；词与词之间无连字符连接、多作状语。例如：
　　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。
　　该结构的主要特点是：不定式用主动形式表示被动意义，它与前面的主语有逻辑的动宾关系。因此，如果动词不定式是不及物动词，则要加上必要的介词或副词。例如：
　　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。

词汇辨析

辨析every day与everyday

　　every day分开写，在句中通常作状语，表示“每天”；
　　everyday合写时在句中通常作定语，表示“每日的；日常的”。例如：
　　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。

辨析contain与include

　　共同点：两者都有“包含”的意思。区别在于：
　　contain可用于包含所含之物的全部或部分；
　　include则只能用于表示所包含之物中的一部分。例如：
　　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.
　　乐队演奏了很多曲子，包括我最喜欢的几首。

辨析method 和way

　　共同点：两者都可以表示“方法”
　　way是普通用语，指做事情的方法，也可泛指思想方法、生活方式等。
　　It is English way of living. 这是英国人的生活方式。
　　method指系统的，具有一定理论性的方法。
　　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

　　共同点：两者都表示同时。
　　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；
　　2）用来说明人或事物的一个方面之外的另一面。
　　Meanwhile意为同时，在此期间，作为副词和名词，表示在某动作或情况发生或存在期间将可能发生另一件事。它不用于说明人或事物的另一面。例如：

www.51jxk.com　　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

共同点：

表示“起初”，最好用in，有时也用at

不同点：

1）后接of短语，指时间，at较常用

2）后接表示地点的名词，用at

3）与at last“最后”相对，常用at

与later对比使用，常用in

　　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。
