Q2: What is the purposes of this article?

Q3: How does the writer feel about modern life? How do you know?

句型梳理

1. The government，however，does not intend to stop the protection

programmes，since the threats to the Tibetan antelope have not yet

disappeared.

语法：本句是复合句，since“因为，既然”，引导原因状语从句，对前面主句进行解释。

since引导的原因状语从句 （1）since引导原因状语从句，位于主句之前或之后，表示已知的、显然的理由，通常翻译成“既然”，与now that可互换，语气比because弱。

Since you are free today，you had better help me with my mathematics.

既然今天你有空，你最好帮我补习数学。 （2）seeing（that）（由于，鉴于），now（that）（既然），considering（that）（考虑到），in that（因为）等连词词组，也引导原因状语从句。

Seeing that you are on a diet，we won't have dessert. 由于你在节食，我们就不吃甜食了。

Now（that）you are grown up，you should not rely on your parents. 既然你长大了，就不应该依靠你的父母了。

Considering（that）everybody is here，let's begin our discussion. 考虑到大家都到了，我们就开始讨论吧。

注：since引导的时间状语从句，表示“自从”，从句时态常用一般过去时，主句时态用现在完成时或现在完成进行时。

I have been missing her since she left.自从她离开我就一直很想念她。

2. Only when we learn to exist in harmony with nature can we stop being a

threat to wildlife and to our planet. 本句是一个复合句。Only when we learn…位于句首，主句can we stop…

是部分倒装句。

“only+状语”结构引起的部分倒装

当only置于句首修饰做状语的副词、介词短语或if，when，because引

导的状语从句时，句子要用部分倒装，即把助动词、情态动词或be动词提到主语前面。

Only then did he realize that he was not fit for the job.

只要坚持 梦想总会实现

3

高中英语讲义

到那时他才意识到他不适合做这项工作。（“only+介词短语”位于句首） 注：only强调主语，句子不必倒装。 Only Tom and John failed in the exam. 只有汤姆和约翰考试没及格。 总结：

（1）在以never，little，hardly，not，seldom，on no account（决不），at no time（决不）等否定副词或短语开头的句子中，采用部分倒装结构。 Little does she know what may happen. 她一点儿也不知道会发生什么事。

（2）在使用so...that...句式时，若“so+形容词/副词”放在句首，主句部分倒装句。 So fast does light travel that it is difficult for us to imagine its speed. 光的传播速度太快，我们很难想象它的速度。
