项正确；温度升高时，瓶内气体分子的平均动能增大，但不是每个分子的动能均增大，项错误；气体压强是由分子对容器壁的频繁碰撞产生的，温度升高，分子热运动的平均动能增加，压强不变，体积增大，故瓶内气体分子在单位时间内与单位面积容器壁的碰撞次数减少，项错误。(2)气温为7℃时油柱刚好处在瓶口位置，此时饮料瓶内气体的体积为V1;当油柱在吸管最右端管口处时气体温度最高，设为T2,此时饮料瓶内空气体积为V2,吸管的有效长度l=45cm,则V2=400cm3+0.4×45cm3。由盖一吕萨克定律有,解得T2=292.6K,故温度计能测出的最高温度为19.6℃。(3)由于气体从外界吸收4J的热量，气体对外做功W=力·△V=1.8J,根据热力学第一定律△U=W+Q,知内能增加量为2.2J。

Kang Heng, 16, hasn’t been sleeping well in a tent the past couple of nights. Closing his eyes only brings repeated terror from all that happened and, worse still, all that could have happened at around 2:30 pm last Monday.

The student in Dongcheng High School in Mianyang, Sichuan Province was on his way to class after an afternoon nap(小睡) when the big earthquake hit the area.

“It’s a complete shock! As soon as I heard someone screaming Earthquake! I saw our classroom building being torn apart just in front of my eyes. The next second I saw a student jumping out of the window from the second floor,” Tang recalled.

As the electricity was cut off, his teachers shouted as loud as they could to gather all the students in the school onto the playground. Although some were wounded by falling objects or injured while running out, they at least escaped death.

Thousands of people, young and old, were buried in ruins, mostly in the small cities and counties, such as Wenchuan, Beichuan, Dujiangyan, Anxian and Qingchuan, which are surrounded(包围) by hills and mountains.

By last Friday, around 19,000 people died because of the earthquake, which is the worst in China in 30 years. And the number is still rising.

More than 100,000 troops have continued to arrive at destroyed areas since the day after the quake hit. And more neighboring people were doing all they can to offer help.

Kang and his parents were among them. They drove in rain to Anxian County, an hour drive away from Mianyang, with water, instant noodles and plastic for building tents. Kang’s family finally found his terrified grandparents in Anxian on Wednesday morning.

“We first thought the worst had happened to my grandparents. But they had a narrow escape and were rescued by kind people, who were completely unknown to us. We are thankful to them and hope to do whatever we could to help others,” said Kang.

1. The underlined word “terror” in Paragraph 1 probably means “_______ ” .

A. fear B. peace C. anger D. power

2.From the passage, we can learn Kang’s grandparents were rescued by ________.

A. some neighbours B. Kang Heng and his classmates

C. some kind people D. Kang Heng and his parents

3. What can we know from Paragraph 5?

A. This strong earthquake is the worst in China in 20 years.

B. The young and the old all died after the earthquake happened.

C. People in hilly and mountainous areas suffered the most in this disaster.

D. Thousands of people were buried in ruins because they live in the countryside.

4. Where does the text probably come from?

A. A research plan. B. A newspaper.

C. An advertisement. D. A science magazine.

2.More than 100,000 troops have continued to arrive at destroyed areas since the day after the quake hit. And more neighboring people were doing all they can to offer help.意思是自从地震发生后一天，10万多士兵就陆续到达受灾地区，并且越来越多的邻近地区的人们尽他们所能去提供帮助。可知是一些善良的人救了他的奶奶，故选C。

3.Thousands of people, young and old, were buried in ruins, mostly in the small cities and counties, such as Wenchuan, Beichuan, Dujiangyan, Anxian and Qingchuan, which are surrounded(包围) by hills and mountains.意思是成千上万的人们，年轻的年老的都被埋在了废墟下，大部分都是像汶川，北川，都江堰，安县和晴川等被山包围的小城里。可排除A，B，D，故选C。
