---Why are you busy these days?

--         I am writing a book.

A.since             B.a(chǎn)s               C.for               D.because

 

【答案】

D

【解析】

試題分析:在表示原因時,for表示推測的原因,一般只能放在句子中間,引導并列句;as從屬連詞,引導原因狀語從句,常位于句首。表示眾所周知,顯而易見的原因。because:語氣最強,表示直接原因,可用于回答 why 提出的問題、引導表語從句、用于強調(diào)句等;since所表示的原因都是人們已知的,即對已知事實提供理由,而不是表示直接原因。since 比 as 語氣稍強,且比 as 略為正式,它引導的從句通常放在主句之前,有時也放在主句之后:句意:這些天你為什么這么忙?——因為我正在寫一本書。結合語境可知選D。

考點:連詞辨析

點評:連詞在句子中主要起聯(lián)系上下文的作用,他們之間的區(qū)別就是表示邏輯關系的不同,所以在解題時先要理解上下文含義,然后根據(jù)上下文邏輯關系選擇合適的連詞。連詞的用法都比較多,語義之間還有交叉,熟記其基本應用規(guī)則,了解其區(qū)別,注意固定搭配對象,是做好此類題型的關鍵。

Fashion isn't very environmentally-friendly because it makes people buy things they don't need, just because they're new. We want to take care of the environment, we don't want to pol­lute the air and we don't want to waste energy and resources. But we also want to be fashiona­ble. How can we buy fashionable clothes and protect the environment?
Old styles are fashionable again, so one way is to buy second-hand clothes — recycled clothes. Another way is to buy' fair trade clothes. These clothes are either recycled or made in a ' way that protects the environment. They also protect the people who make the clothes.
Surprisingly, white cotton is one of the least environmentally-friendly crops of all. To pro­tect the cotton, the growers use chemicals that pollute water, make farm workers ill and kill wildlife. New materials, such as hemp and bamboo, grow quickly and are more environmental­ly-friendly. These materials are very soft, and look fantastic. The best materials are coloured using natural dyes, made from plants.
Environmentally-friendly clothes are practical but until now they were often dull. Now fashion-designers are working with these materials and the clothes are beautiful as well. So now we can buy fashionable clothes that are also environmentally-friendly.
【小題1】Why do people often buy things they don't need? Because_.
A.new things can be more comfortable
B.everyone wants to be fashionable
C.people are richer than before now
D.people care about the environment
【小題2】What's the topic for paragraph 2?
A. Recycled fashion. B. The problem with fashion.

【小題3】Which of the following is more environmentally-friendly?
A.Materials soft and looking fantastic.
B.Any materials coloured using natural dyes.

D.White cotton.
【小題4】Why are environmentally -friendly clothes more fashionable now? Because______.
A.people pay more attention to our environment
B.environmentally-friendly clothes are practical
C.a(chǎn)ll old styles become fashionable again
D.fashion-designers are working to make them beautiful
【小題5】What is the best title for the passage?
A.Cotton or Hemp and Bamboo?
B.Environmentally-friendly Clothes
C.Old Style, New Fashion Again
D.Fashion and the Environment

Put 2 February in your diary! It is World Wetlands Day! It marks the date that the

Convention(公約) on Wetlands was signed(簽署)in1971.This special day was first celebrated in 1997 and it is celebrated every year.
