【核心句型】

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.

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。

3. [句型公式]　This is why...“这就是……的原因”

(教材p.16)This is why we're here—to observe Tibetan antelopes.

这就是我们来到此地的原因——观察藏羚羊。

The sun was shining on the white sand of Dadonghai Bay when Stanley,an endangered sea turtle,was struggling to go back into the ocean to begin its new life.　1　.It hatched prematurely(过早地) when it was found by fishermen on an island in the South China Sea. 

“It just couldn’t move.Usually,　2　,they’re very active and scrabbling across the beach really fast,” he said.“It’s like a kind of craziness and that’s what gets them past all the predators(捕食者).” 

　3　.Within a week of being found,it was delivered to the sea turtle hospital and laboratory at Hainan Normal University in Haikou for treatment. 

Dozens of other endangered sea turtles just like Stanley have been recovered at the hospitals and labs on Hainan Island,supervised by Sea Turtles 911’s Yeh and Hainan Normal University Professor Haitao Shi.

　4　.The labs are located in a village on the coast,or at the Ritz-Carlton Sanya in Yalong Bay,which teamed up with Sea Turtles 911 to build a Sea Turtle Shelter on the resort’s grounds,and get a chance to see the creatures up close.It’s a rare opportunity,　5　. 

But with sea turtle meat and shells in high demand for years across China,the animals stopped coming to Hainan to lay eggs in the past 30 years.Now,Yeh and Shi hope to bring them back by educating the population,raising awareness among tourists and releasing seized turtles.

D.Stanley might not have made it there at all

E.because it is listed as an endangered animal

F.Volunteers and tourists visit the turtle labs at the university

Ⅰ.阅读理解

It was a still African evening and Shirley Strum was writing down observations as she watched the behaviour of one of her favourite baboons (狒狒),Naomi.Suddenly,Shirley felt small hands softly touching her back.Surprised and puzzled,she slowly turned her head and saw it was Robin,Naomi’s two-year-old offspring (后代).Ms Strum was thrilled,for she knew that such comforting gestures were the baboons’ way of establishing and keeping their relationships with one another.It seemed that the group of baboons had come to accept and trust her.

The group of monkeys in Kenya was known as the “Pumphouse Gang”.Of course,it was not really a gang,but one of nine troops of baboons totaling about eight hundred animals.They live around Lake Elmenteita,famous for its flamingos and pelicans.This particular group had been given its name because it was often seen near a water-pumping station.

Probably the most significant conclusion she reached from her research was that the stable core of baboon troops isn’t the powerful adult males,as had been originally thought,but is the family groups of mothers and their off spring.Strum discovered that adult males move from group to group,changing their friendships frequently,but the females’ relationships remain unchanging.

Baboons,the largest monkeys on the African continent,are also the most adaptable.This adaptability is particularly noticeable in their diet.The “Pumphouse Gang” had a very diverse diet,which enabled them to survive bad times when other wildlife in the area died.Baboons eat grass.But since they have to compete with other animals for this food,they add seeds,roots and flowers in their diet.They also enjoy insects and are not averse to a good piece of meat now and then.

Strum says she did not have a single boring moment during her sixteen months studying the baboons.She believes that many old views about these monkeys need to be changed.By continuing our observations of nonhuman monkey behaviour,Strum thinks we can gain a better understanding of ourselves,of what we share with other monkeys,and of what is uniquely ours.

【语篇解读】本文详细介绍了Shirley Strum对狒狒的最新研究成果,修正了某些以前对狒狒的错误认识。

1.What indicated that Shirley Strum was acknowledged by the baboons?

A.She could get close to observe their behaviour freely.

B.Robin put the small hands gently on her back from behind.

C.Naomi and Robin frequently played games with her at night.

D.Naomi helped her to write down observations with performance.

2.Why was the group of monkeys in Kenya named “Pumphouse Gang”?

A.Because they fed on flamingos and pelicans.

B.Because they lived near a water-pumping station.

C.Because they consisted of nine troops of baboons.

D.Because they were made up of eight hundred animals.

3.What does Shirley Strum approve of?

A.The offspring of baboons know their mother but not their father.

B.The core of a group of baboons tends to be the strongest adult male.

C.Baboons have to eat other dead animals to live through difficult times.

D.Baboons are the largest and strongest animals on the African continent.

4.What’s the probable meaning of the underlined word “averse” in Paragraph 4?　　　　　　　　　　　　　　

A.Devoted. B.Accustomed.

C.Addicted. D.Opposed.
