七、阅读理解
“cool” is a word with many meanings. its old meaning is used to express a
temperature that is a little bit cold. as the world has changed, the word has had many
different meanings. “cool” can be used to express feelings of interest in almost everything.
when you see a famous car in the street, maybe you will say. “it’s cool.” you
may think,“he’s so cool,”when you see your favourite football player.
we all maximize(扩大)the meaning of “cool”. you can use it instead of many
words, such as “new” or“surprising”.here’s an interesting story we can use to
show the way the word is used. a teacher asked her student to write about the
waterfall(瀑布) they had visited. on the student’s paper was just the one
sentence,“it’s so cool.”maybe he thought it was the best way to show what he saw
and felt.
but the story also shows a scarcity(缺乏)of words. without “cool”, some people
have no words to show the same meaning. so it is quite important to keep some
credibility(可信性).can you think of many other words that make your life as
colourful as the word “cool”? i can. and i think they are also very cool.

all over the world compete in the kite flying. There are also competitions for the best kites. The kites in the competition are all made by hand.
Most people have flown a kite. It makes people happy. It’s easy to make it. It’s made of bamboo and paper. But not so many people know that kites were first made in China thousands of years ago. The ancient Chinese made and flew kites even before they could write.
A long time ago, the Chinese made kites to use in wars. They would fly these war kites in the dark. The kites were fixed and they made strange sounds in wind. Men who were at war against them would hear these sounds and run away. They thought those strange sounds were made by gods in the sky.
The ancient Chinese also flew kites to bring good luck and to make their crops grow rich and tall. Sometimes they tied long strings and hooks(钩子) to their kites. Then they would fly the kites over water, letting the hooks hang down to catch fish.
The Chinese use sticks, string and paper for their kites. Some of these kites look like animals or trees and others look like houses.

she liked better, chocolate or toys. She chose chocolate. Then he asked her to choose again between chocolate and chocolate. Of course, she didn’t have a choice.
This exercise told us that sometimes we don’t have a choice in life, and that sometimes we have to accept something, rather than complaining(抱怨).
A girl stood up and started talking about her mom who was a drug addict (吸毒者)and how much she hated her mother.
“I want a new mom,” she cried.
“Unluckily, you can’t have one,” the leader replied.
“You have to accept the mother that you have.”

What is the hottest English word of 2013? It’s “selfie”, according to Oxford dictionaries. Selfie is a photo that one takes of oneself, according to the Oxford online dictionary. People usually take selfies with a smartphone(智能手机) and send them to a social media website.

“Almost every day, I take a photo of myself at school, and save it in my Qzone (QQ空间),” said Huang Xu, 13, from Hunan. These photos record her happy and sad moments.
Pop stars also take a lot of selfies. Li Chunping, 14, from Harbin, is a big fan of Yang Mi. “She has used many selfies to tell us what’s going on in her personal life,” said Li.
What makes people love selfies? Some people say it’s narcissism (自恋). “The rise of the selfie is a perfect symbol for our narcissistic culture. We’re crying out: Look at me!” said US psychiatrist(精神科医生) Carole Lieberman.
Young people are using selfies to make friends online, Jonathan Freedland wrote in The Guardian. “The usual purpose of taking a selfie is to share online. They express a human need to connect with others,” wrote Freedland.
Huang Xu agrees with that. “During summer vacation, my classmates and I shared many selfies online. Hair or clothes were not our interests. Through these photos, we got to know each other’s holidays and feelings,” said Huang Xu.

.
“Thank you” is widely in a modern society. It is a very good manner. You should say “Thank you” others help you or say something kind to you. For example, when someone the door for you, when someone says you have done your work well, when someone says you have a nice shirt, or your city very beautiful, you should say “Thank you”. It is used not only between friends, but also between parents and children, sisters, husbands and wives.
“Excuse me” is short polite usage. We use it the same as “Thank you”. When you hear someone says so behind you, you’ll get to know that somebody wants to walk past touching you. It is not polite to interrupt(打断) others while they are one of them, please say “Excuse me” , and then begin to talk. You should also do so when you want to cough or make any unpleasant noise before others. Let’s say “Thank you” and “Excuse me” on the right situation.

三、简答题
19、答：砂石的比热小于水的比热，夏天在相同的日照即吸收相同的热量时，砂石升高的温度高于水升高的温度。因此，人在砂石上感到烫脚，再走入水中，水的温度低于砂石温度，又会感觉凉快。
四、计算题
20、解：Q吸=c水m(t-t0) =4.2×103 J/(kg·℃)×80 kg×(60℃-10℃) =1.68×107 J 21、解：Q放=Cm( t0-t)
Q放4.2?106
m???125(kg) C(t0?t)4.2?103?(80?72)
22、解：因为Q放=qm,所以m煤=Q放/q=1.38×108J/4.6×107J/kg=3kg.
若实际燃烧5kg,则有Q吸=Q放=1.38×108J，
Q放'=qm=5kg×4.6×107J/kg=2.3×108J
所以η=Q吸╱Q放’=1.38×108J/2.3×108J=60%
