Since the Internet came into homes, the daily life has never been the same again. But the thing that worries most of us is that we can get viruses from the Internet. But can we catch viruses on our cell phones? A new study in the journal Science says yes, but the spread of such mobile software that can bring harm to our cell phones won’t reach dangerous levels until more cell phones are on the same operating system.
Computers are easily attacked by viruses because they share data, especially over the Internet. Of course, nowadays, more people are using their cell phones more and more frequently. They use them for emailing, text messaging and downloading troublesome ring tones, etc.,so it is obvious that cell phone viruses are a threat as well.
Scientists used nameless call data from more than six million cell phone users to help model a possible outbreak. And they concluded that viruses that spread from phone to phone by Bluetooth are not much concerned, because users have to be in close physical relation for their phones to “see” one another. However, viruses that spread through multimedia messaging services can move much faster, because they can come in disguise(伪装), such as a cool tune sent by a friend. The good news is that to be effective, these viruses need their victims(受害人) to all use the same operating system, which not enough of us do. Because there is no Microsoft operating system for mobile phones, yet. Thank goodness.
What is the passage mainly about?

A.The operating system of cell phones.
B.The threat of cell phone viruses.
C.The wide use of cell phones.
D.Computer viruses.

When ______, cell phone viruses can be dangerous.

A.all the cell phones work on the same operating system
B.Microsoft operating system for cell phones is created
C.users can see each other on the phones
D.Bluetooth is widely used

What can we infer about Bluetooth according to the scientists?

A.It can increase the chances of cell phone viruses greatly.
B.It can help us to stop the spreading of cell phone viruses.
C.It won’t possibly cause the outbreak of cell phone viruses.
D.It can make users have close physical relation with one another.

We can learn from the passage that ______.

A.it is impossible to catch viruses on our cell phones
B.cell phones are not well connected with the Internet
C.it is dangerous for people to download ring tones to cell phones
D.more than one operating system is used for cell phones now

Nobody likes staying at home in a public holiday, especially when the weather is fine. Last august we decided to spend the day in the country. The only difficulty was that millions of other people had exactly the same idea. We moved out of the city slowly behind a long line of cars. But at last we came to a quiet country road and after some time, stopped at a lonely farm. We had brought plenty of food with us and we got it out of the car. It was very peaceful in the cool grass until we heard ringing at the top of the hill. What we saw made us pick up our things and run back to the car as quickly as possible. There were about two hundred sheep coming towards us down the path.

阅读下面的短文,并根据短文后的要求答题。(请注意问题后的字数要求)。
Many students find it hard to make friends when they are in high school. Keeping my suggestions in mind may give you a hand. They certainly helped me, and by the end of my three years of high school, I had formed my group of friends, with whom I still keep in touch now.
Here are my tips:
Say hello anytime I see an acquaintance(相识的人).
Because I was always smiling and greeting the people I knew, people naturally thought I was friendly(though I am not naturally sociable). And high school students want to be friends with sociable people.
Take the first step.
All the girls there already knew each other—they didn't need another friend. But I did, so I had to make the effort. I had to be the first one to invite somebody to go to a movie with me, or come to my house. Once I did that they started to respond with the same thing.
Use classes to get to know people.
I met most of my first friends because I sat next to them in class. Class(before, after, or even during class time)is a great opportunity to begin a conversation. For example, ask for help about homework.
Make friends slowly.
I couldn't get discouraged (泄气的) when it took a while to make friends.It really takes some time to make new friends. In a word, ________________________.
 Above all, remember that it can and will get better. You may have to work a little to make your high school experience a great one, but it's really worth it!
For what purpose does the writer write this passage?(Please answer within 15 words.)
Which sentence in the passage is the closest in meaning to the following one?
I was believed to be sociable because of my friendly attitude towards others.
Fill in the blank with a sentence.(Please answer within 10 words.)
Which piece of advice does the following sentence belong to? (Write in detail)
Everybody should make friends patiently in high school.
Translate the underlined sentence in the first paragraph into Chinese.

Success is often measured by the ability to overcome adversity(逆境). But it is often the belief of others that gives us the courage(勇气)to try.
J. K. Rowling, author of the Harry Potter book series, began writing at age 6. Her good friend-Sean became the first person to encourage her and help her build the confidence that one day she would be a very good writer.
“He was the first person with whom I really discussed my serious ambition(志向) to be a writer. He was also the only person who thought I was bound to(注定)be a success at it, which meant much more to me than I ever told him at the time.”
Though there were many difficulties, Rowling continued her writing, particularly fantasy stories. But it wasn't until l990 that she first came up with the idea about Harry Potter. As she recalls(回忆), it was on a long train journey from London to Manchester that “the idea of Harry Potter simply fell into my head. To my great disappointment, I didn't have a pen with me, and I was too shy to ask anybody if I could borrow one. I think, now, that this was probably a good thing, because I simply sat and thought, for four (delayed train) hours, and all the details came up in my brain, and this thin, black-haired, bespectacled(戴眼镜的)boy who didn't know he was a wizard became more and more real to me.”
That same year, her mother died after a ten-year fight with serious diseases, which deeply affected her writing. She went on to marry and had a daughter, but separated from her husband shortly afterwards.
During this time, Rowling was diagnosed with depression(诊断患有抑郁症). Unemployed, she finished her first novel in area cafes, where she could get her daughter to fall asleep. After being refused by l2 publishing houses, the first Harry Potter novel was sold to a small British publishing house.
Now with seven books that have sold nearly 400 million copies in 64 languages, J. K. Rowling is the highest earning novelist in history. And it all began with her friend’s encouragement as well as her ambition to write.

Pets are popular. They’re good listeners, they encourage us to exercise, and they’re always on our side when we argue with others. They can bring people comfort and pleasure.
But it is important to keep in mind that pets can carry diseases that can make you sick. Washing your hands often — especially after you touch, feed, or clean up a pet — is the best way to keep yourself healthy and prevent the spread of disease. Be sure to clean your fingernails(指甲)carefully every time you wash.
You also can protect your health by wearing gloves while cleaning animal cages or cat litter boxes. Avoid washing your pet in the bathtub (浴缸), but if you do, always disinfect (消毒) the tub immediately afterward.
Be sure to bring your pet to the hospital for examinations every two weeks or month and whenever your pet is sick or injured.
You can do a few other things to keep yourself and your pet healthy. Only give your pet food that has been planned ahead for them. It’s not a good idea to share your food with your pet. Human food (like chocolate) can make animals sick. Never feed your pet raw meat because it can carry germs (细菌) that cause serious illness.
And funny as it can be to see your dog or cat drinking from the toilet, don’t let pets do this. It’s bad for your pet’s health! Give them clean, fresh water to drink at all times.
Never give milk to cats. The only milk an animal should drink is from its mother. Cow’s milk is not for pets, especially for cats, as it makes them sick.
Finally, some animals aren’t pets. Don’t take in a wild or abandoned (被抛弃的) animal as a pet because it may have diseases that could make you or your family sick. Instead, turn to an animal rescue group that is trained in helping sick or abandoned animals.

One day I heard that one of my dear friends had lost his mother. This made me sad, for my friend was very close to his mother. He had been by her side as she traveled through her long and hard journey with cancer. At this time, many memories about my loved ones that had passed away came flooding to me. Finally these memories passed, but it was really sad to think that my friend would have to go through the pain.
Three times I tried to write an email to my friend and three times words failed me. I am a person who is not often lost for words and I decided to have a sleep. Upon waking up I could hardly wait for my computer to work, the words I needed were there. I was still left with a heavy heart although I had sent an email.
Everything in this universe is balanced and indeed it is. Three days later, I received his reply letter. I was happy to hear that he’d been admitted to (录取) Cambridge University. It served as a gentle reminder for me that my friend would be okay and that life would go on.
Everything in life is balanced; the lowest feelings change places with the highest feelings. Without the lows, we would never appreciate the highs. No matter how dark the clouds seem to be, the sunshine is always there and just waiting for the opportunity to shine through.
