THE FEAST：18，000 BC①
Worried about the preparations for her feast②， Lala quickly turned for home with her collection of nuts，melons③ and other fruit. It was the custom of family groups to separate④ and then gather again at different sites for reunious as they followed the animal herds across the grasslands⑤。

A wrinkle⑥appeared on her forehead. If only it could be just like last year⑦！ At that time she had been so happy when Dahu chose⑧her as the future mother of his children. He was the best toolmaker in the group and it was a great honour⑨for her to be chosen。

She remembered the blood pulsing⑩through her veins⑪。

She had felt so proud as the group shouted loudly to applaud⑫ his choice ⑬. If only she had looked ahead⑭ and planned better this year! Then she wouldn't have been feeling so worried now。

这些工具同其他一些锐利的箭头和石斧头堆放在一起。

他选了一块大石头，开始用它作锤子敲打一个需要磨快的石刮子边缘.他时不时地停下来看看，在手上试一试,然后再继续工作。

当他觉得石刮子够快，能够切碎肉并能刮鱼鳞了，他才停下来。

他把它们递给拉拉，这时候,来自邻近洞穴的第一批客人就开始来吃饭了.拉拉情绪高涨起来了。

二、勤练高考题型，多练自能生巧
Ⅰ.阅读理解
Clover, a three­year。

old spirit bear， lives at the B．C. Wildlife Park near Kamloops， British Columbia， Canada. He lost his parents two years ago and was raised at a wildlife center。

When he was set free into the wild, he broke into human camps looking for food. Wildlife experts （专家) tried to get him used to living on his own，but he continued to look for places where there were people. Finally the experts decided that he could not live in the wild。

Since then, a total of ＄750,000 has been collected to create a habitat for Clover。

The habitat covers about three acres (英亩) of land and includes natural forest， two ponds connected by a small river and something else. It will add a platform and a walkway later this year so that people can see Clover and his habitat more closely。

There will also be a center where people can learn more about spirit bears. Besides, a black bear will be moved into the habitat so Clover will not feel lonely.
Spirit bears are also called Kermode bears after Francis Kermode， who first studied them。

Kermode discovered that a small number of black bears carry a gene （基因) for white fur. If a baby bear receives one of these genes from each parent， its fur will be a creamy white color。

There are about 1，200 bears who carry the gene for white fur， but only about 200 white Kermode bears in the world. Kermode bears are found only in British Columbia。

They live in the Great Bear Rainforest, an area that covers the
mainland and islands along the coast of B．C. between Vancouver and Alaska。

3．What will Clover's future life be like？
A．Busy. B．Easy。

C．Hard. D．Lonely.
解析：选B 推理判断题。

由第一段中的“a total of $750，000 。

something else”和“so Clover will not feel lonely”可知,Clover将来在新家的生活会很舒适,故选B项。

阅读七选五
Common public speaking problems
The use of “I feel"，“I think" and “maybe”
In the question.and。

answer session of the speaking competition, many contestants began their answers with uncertain expressions like “I feel”,“I guess”，“I hear”，“maybe" and “perhaps”．
These words show that the person is only speaking from his or her point of view。

__1__.
Work on keeping your answers brief and to the point。

Also work on delivering them with calmness and confidence。

Instead of the empty.sounding “I guess”， using facts，together with a clear conclusion based on those facts， is far more likely to be popular with an audience。

__2__
Don't stick to the same tone。

It can be boring. Try to mix it up。

For example，when people spoke about their dreams， some sounded romantic。

Others used humor。

Very few used several different styles together。

__3__, rather than just sticking with the same one。

Irresponsible answers
__4__。

You’re responsible for your words。

Even though you want to answer quickly, you don't want to sound foolish。

So you should think twice before you talk。

Don’t be like the student who, when asked about his opinion on book piracy (盗版行为）， started by saying he supported it.
Talking around the topic rather than directly answering it
You should focus on one point and give a clear solution。

__5__. Is it asking you to discuss a certain topic or to present your own point of view?
Use one or two arguments together and give a strong conclusion。

Remember that judges are not judging you on whether they agree， but on your ability to say what you think clearly。

A．Try mixing more than one style
B．Improving your communication skill
C．Using only one speaking style
D．It's important to involve your audience
E．Public speaking is different from personal conversations
F．The key is to work out what question is being asked
G．To the judges and audience， this lacks the support of facts and seems not to be reliable
or her point of view。

"可知，这样的语言只是个人观点，给人不可靠的感觉，所以选G项.
2．选C 空处是本段的小标题，由下文提到的“Don't stick to the same tone"和“mix it up"以及“rather than just sticking with the same one”可知,本段主要讲述说话语气和风格要多样，不要固定于某种模式，故选C项。

3．选A 本空是连接句，由上文提到的“Try to mix it up”可知，你需要融合更多的说话语气和风格，这与A项一致，所以选A项。

4．选E 本空是段落起始句，由下文的“You’re responsible for your words 。

should think twice”并结合小标题可知，公众演讲时你要对你的回答负责,公众演讲不同于个人谈话,所以选E项。

5．选F 本空是连接句,根据本段小标题和下文的“a certain topic or to present your own point of view”可知，讲话需要有针对性,要清楚问的是什么问题,所以选F项。
