②The number of the books in our library is about 45,000.我们图书馆藏书量大约为4万5千册。

year by year 与year after year

year by year即“逐年,每一年”,强调“年年在变”,

The boy grows taller year by year这个孩子长得一年比一年高。

year after year意含时间的重复性,即“每年固定发生,年年如此”。

He went to Beijing on business year after year.他每年到北京当差。

例The number of computers is increasing _____, which has brought the price down.

A. year by year  B. year after year  C. years after years  D. years by years

解析:句意为:电脑数量逐年增长,使得价格下降。本题考查year by year 与year after year的区别。year by year 意为“年年在变”;year after year意为“年年如此”。由句意可知答案为A。

research与search

相同点:两词均有研究、探索之意。

research指审慎的或精密的探究,有科学的研究或批判的研究之意。一般批学问、宗教、物理、心理、天文等方面调查或研究,常用复数。

search则有搜索、探索之意、侧重对某事持续的调查或研究,用于搜索或寻找失窃物品或探究知识、真理、自由、珍禽、奇术等方面。举例如下:

They are researching on the effects of cigarette smoking. 他们正在研究吸烟的后果。

He went all over the world to search after truth. 为追求真理他行遍全球。

travel, journey, trip, tour, voyage

相同点:这五个词都作“旅行”解。

Travel:可作动词或名词,指远距离长期的旅行,没有具体的目的和方向性。常用来表示“旅行”这一概念。名词的复数形式travels表示旅行经历。

journey:使用范围很广,但常指距离较远的陆路旅行,而且有预定的地点,带有明确的方向性。

Trip:常指距离短且直接到达目的地的旅行。在口语中trip与journey常常通用。

Tour:含有“观光”的意思,距离可长可短。可作动词或名词。

Voyage:指“航行,航海”指水路或航空旅行。举例如下:

He has travelled all over Africa many times in his life. 他一生中多次到非洲旅行。

Marco Polo wrote a book about his travels in China,which is called The Travels of Marco Polo.

马可波罗把他在中国的旅行写成了一本书,书名叫《马可波罗游记》。

Mr. Black is on his journey to Shanghai.布莱克先生正在去上海的旅途中。

We are planning to make a trip to the Great. Wall.我们正计划去长城游览。

I'm going on a shopping tour. Would you like to go with me? 我想去逛商店,你想不想跟我一起去?

They're making a voyage to Africa. 他们正在作一次去非洲的航海旅行。

难句分析

In fact, there are so many deer that some are being sent to nature reserves by environmentalists who would like to return them to the wild.其实,现在这种麋鹿已经相当多了,有一些正在被送往那些愿意把麋鹿送回野外去的地方。

1)该句是一个较为复杂的复合句,主句为…there are so many deer, that引导的是结果状语从句。

在这个so……that结构中,中心词是名词deer,本应该用such…that结构,但因名词前有many修饰而用了so……that结构,此特殊用法需注意。

2)are being sent是现在进行时的被动语态形式,表示“正在被送往”,其中的being容易被误省。又如本课中的其他两句:
