Dear Charlie,
I’m writing to ask you the favor. To help us students have a better understand of American culture, the Student Union is now organized an American Culture Festival. We’re now bad in need of several American popular magazine that can reflect modern American life. So, could you please help buy some or send them to us? We will cover all the related to costs. Also, we would appreciate if you could see to it that the contents of the magazines were suitable for Chinese middle school students.
Thanks a lot! Please replying at your earliest convenience!
Yours,

House fires cause many deaths each year.1.. So, it's important to teach them that fire is a tool, not a toy. Kids must understand that they'd better not play with fire. You should keep matches and lighters out of their reach.
A smoke alarm greatly reduces your chances of being hurt in a fire, especially when you are in your dream. 2.. Also, you ought to have two plans for getting out of your house if there is a fire and practice these plans in the dark with your family.
A smoke alarm warns you of the danger. When you hear it, take action immediately. When you come to a closed door, check it with the back of your hand. If it feels hot, there may be smoke or fire behind the door, so take care. 3. , call the fire department from a neighbor's house. If a family member or a pet is caught inside, you shouldn't go back in. Firemen know how to perform rescues safely.
4. . Change the batteries at least once a year. You should use the test button each month to see if the alarm and batteries are still working. A smoke alarm lasts about ten years. You ought to change it even if it seems to be working. Every year the fire and rescue service is called to over 600,000 fires, which result in over 800 deaths and over 17,000 injuries. 5. .
A. Once you are out of your house
B. Make sure of working hours of fire fighters
C. A large number of these fires are set by kids
D. Although your friends know how to put out fire
E. So you should have a smoke alarm outside your bedroom
F. But remember, the alarm can work only if it has enough power
G. Actually most of them can be avoided with working smoke alarms
People have been wondering why elephants do not develop cancer even though they have lifespans (寿命) that are similar to humans, jiving for around 50 to 70 years.
Now scientists believe they know why. A team at the University of Chicago, US has found that elephants carry a large number of genes that stop tumors (肿瘤) developing. To be precise, they found 20 copies of an anti-tumor gene called TP53 in elephants. Most other species, including humans, only carry one copy.
According to the research, the extra copies of the gene improved the animal’s sensitivity to DNA damage, which lets the cells quickly kill themselves when damaged before they can go on to form deadly tumors.
“An increased risk of developing cancer has stood in the way of the evolution of large body sizes in many animals,” the study author Dr Vincent Lynch told The Guardian. If every living cell has the same chance of becoming cancerous (癌变的), large creatures with a long lifespan like whales and elephants should have a greater risk of developing cancer than humans and mice. But across species, the risk of cancer does not show a connection with body mass.
This phenomenon was found by Oxford University scientist Richard Peto in the 1970s and later named “Peto’s paradox (悖论)”. Biologists believe it results from larger animals using protection that many smaller animals do not. In the elephant’s case, the making of TP53 is nature’s way of keeping this species alive.
The study also found that when the same genes were brought to life in mice, they had the same cancer resistance as elephants. This means researchers could use the discovery to develop new treatments that can help stop cancers spreading or even developing in the first place.
“Nature has already figured out how to prevent cancer,” said Joshua Schiffman, a biologist at the School of Medicine, University of Utah, US. “It’s up to us to learn how different animals deal with the problem so that we can use those strategies to prevent cancer in people.”
1.Why are elephants unlikely to develop cancer?
A.They have a rather large body size.
B.Their genes suffer no DNA damage.
C.Certain genes in their body kill existing tumors.
D.They carry many genes to prevent tumors developing.
2.According to the passage, what has been a risk in the evolution of large animals?
A.Deadly tumors. B.The huge body mass.
C.Cells killing themselves. D.Sensitivity to DNA damage.
3.What does the underlined part “This phenomenon” in Paragraph 5 probably refer to?
A.Larger animals have protection from TP53.
B.The risk of cancer is not related to body size.
C.Larger animals suffer the same risk of cancer as smaller ones.
D.The larger animals are, the bigger risk of cancer they will have.
4.What can be concluded from the passage?
A.Depending on nature is surely enough to fight against cancer.
B.The TP53 genes have proved useful in stopping cancer in people.
C.Humans are expected to prevent cancer with the making of TP53.
D.The extra copies of elephants, genes are used to cure cancer patients.
The stories we share with one another are important. They show wisdom and provide inspiration. They are important to our development. But sometimes people choose not to tell.
Consider the negative effects of not sharing a story in the news: People are wondering if public health officials are holding back too much information about the recent outbreak of Ebola.
There is a danger in holding back stories that ought to be told. Bobette Buster said it like this, “The fact is, history has shown us that stories not told can become like a dangerous genie (妖怪) left in a bottle. When they are finally uncorked, their power to destroy is set free.”
There are a number of reasons why we hide parts of our story: they often show our weaknesses or expose our disadvantages; they require courage and strength to share; and of course, there are some stories that should be kept secret—especially those that embarrass someone else.
Most of us have two selves: the one we display on the outside and the one we actually are on the inside. And the better we get at hiding the stories that show our true selves, the more damage we may be causing to ourselves and to others.
Honesty and openness is important: it proves we are trustworthy. It displays we are human. We are not perfect or better. It highlights the importance of hard work and personal development. Hard work may not allow us to overcome our disadvantages completely. But with hard work, we do not have to be restricted to our mistakes.
Does this mean we admit every weakness, every disadvantage, and every secret regret to everybody we meet? No, of course not. There is a time and a place and a certain level of relationship necessary for some stories to be told in an appropriate manner.
1.What’s the function of the example in Paragraph 2?
A.It reflects that people are concerning about the spread of Ebola.
B.It shows the bad effect caused by sharing a story.
C.It proves not sharing a story can cause trouble.
D.It concludes that one should share a story at a proper time.
2.Which is close in meaning to the underlined word “uncorked” in Paragraph 3?
A.freed B.broken
C.unfolded D.untouched
3.One of the reasons why people are unwilling to share experiences is that _______.
A.story-sharing highlights the importance of hard work
B.people are used to exposing their weaknesses
C.people sometimes have no courage to share their stories
D.some stories make themselves feel sad
4.The writer aims to convince us to _______.
A.be open to people close to you by sharing some secrets
B.share stories appropriately for the good of others and ourselves
C.remove the dangers that can be caused by untold stories
D.realize the importance of being honest when making friends
