The “best years of your life”? Maybe not, but you can learn to make the most of your high school days.
Learn to appreciate small things. Whether it's having a computer, having friends, having a good supply of food, a bed to sleep on, family that loves you, having a good education or simply being born in this world.1. Be happy, and life will reward you. Remember that these are the last few years you will be able to enjoy yourself without having to worry about the responsibility of an adult, but make sure you prepare yourself for when you do become one.
2. Unlike what many articles state, you don't have to be popular and have many friends to be happy. 3. Try to have friends that like you who you are, not just because you are wearing a certain brand of shoes or something like that. These are people who shop at the same store as you; not someone who will sympathize with you when your dog dies.
Be sociable.4. While you only need 4 or 5 close friends, that doesn't mean you shouldn't try to meet new people. Participating gives you something to do instead of sitting bored at home .
5. Video games, for example, are good if you're the type who can get into that kind of thing. You should also find a hobby that is meaningful or practical. Use your “hobby time” to either volunteer (to gain practical skills for college apps, job resumes, and scholarships) or learn an instrument, or get into something else in the creative field like painting or dance.
A.You can pursue interests you enjoy.
B.A friend in need is a friend indeed .

This year’s flu season is pretty scary. To try to minimize the effects, public officials are still urging anyone who hasn’t yet gotten their flu shot to get one as soon as possible. However, even if every single person got a shot in the arm, the vaccine(疫 苗)—with its excellent 36 percent effectiveness—would not prevent everyone from getting infected with the annoying virus. Knowledge is power, so here's what goes on in your body when you come down with the flu.
The influenza virus primarily attacks your nose, throat, and the tubes that lead to your lungs. But the flu is so much more than that. Your muscles ache, your head hurts, and your appetite goes down, among other things. To our surprise, almost all of these symptoms have less to do with the virus itself than with your immune( 免 疫 的)response to them. Unfortunately, the very defense you have in place to get rid of the flu is the reason you feel so painful when you recover.
The virus usually enters through your mouth, typically by way of your hands . But it takes a few days for symptoms to set in. While this process might cause some harm to your nose and throat, it's nothing major, and nothing like the symptoms that typically accompany a bad or even mild case of the flu.
The real fun starts when your immune system begins to fight. Your immune system comes in two parts: the innate system and the adaptive. The innate immune system is essentially an all-purpose tool. As soon as your body senses the presence of any injury or invader , the innate immune system launches into action by producing tiny proteins called cytokines and chemokines. The cytokines reproduce almost immediately and start to attack the virus. This increase in immune cells creates a serious inflammation( 炎 症 ) throughout the body. But the worst is still to come.
Meanwhile, the chemokines work with the adaptive immune system to help create T cells. These cells are a special type of white blood cell that works in a much more specific way: They find the influenza virus, identify what's special about it, and create something unique on their surface that finds and destroys similar invaders.
1.What can we infer from Paragraph 1?
A. All the vaccine is not effective.
B. No one can avoid catching this year's flu.
C. This year's flu is the most serious one in recent years.
D. Public health officials have to use a gun when necessary.
2.Why many parts of your body suffer while you're recovering from a flu?
A. Because recovery from illness is painful.
B. Because your immune system is working against your defense system.
C. Because your body is fighting hard against the flu.
D. Because the influenza virus attacks your nose, throat and other parts.
3.The underlined word “fun” in Paragraph 4 can be replaced by .
A. joy B. battle
C. action D. program
4.What's the main idea of Paragraph 4?
A. The fight between innate immune system and the adaptive.
B. The categories of immune system.
C. The way immune system works.
D. The process of the development of immune system.
Does your local high school have a student newspaper? Only 1 in 8 of New York’s public high schools has student newspapers – and many of those are published just a few times a year. A few more are online, which can leave out poorer schools.
Rebecca Dwarka, an 18-year-old senior who works for her student paper said, “Facebook is the new way of finding out what happened. Nobody wants to actually sit down and read a whole article about it. This makes a ‘whole article’ sound a little like a long sentence in lonely places.”
I am not nostalgic about high school student newspapers and never worked for mine. I put out what was then called a personal magazine with a group of friends because we wanted to write about peace, war and rock ’n’ roll without school officials warning us not to make jokes about the local officials.
School newspapers are in decline because students now find out what happened on social networking websites. This is a little discouraging because it proves that for millions of Americans, journalism is becoming a do-it-yourself thing. Every citizen can be a reporter.
When something happens, we look for social media messages. Facebook posts and Tweets have become the means by which citizens and reporters can prove, deny, pass on stories and express opinions without the press’ challenging, researching or slowing the message.
But truly good journalism is a craft, not just a blog post. It requires seeing something carefully and it uses an eye for details to help prove a larger view. And even journalism that conveys an opinion tries to be fair. If school newspapers begin to disappear, I hope there are other ways for students to learn that.
1.What can we infer from Rebecca’s words?
A. Students like reading detailed articles.
B. School newspapers are becoming unpopular.
C. Facebook is the quickest way of spreading news.
D. Long sentences are becoming popular in lonely places.
2.What does the author think of social media messages?
A. They make journalism become a craft.
B. They represent the power of small voices.
C. They are usually discouraging for readers.
D. They are coming without careful research.
3.What should good journalism do according to the author?
A. Ignore some details.
B. Spread a message quickly.
C. Convey an opinion in a fair way.
D. Act as blog posts in modern times.
4.Which might be the most suitable title for the passage?
A. Social media or newspapers?
B. Everyone can become a reporter at present
C. Social networking brings about new journalism
D. High school newspapers – an endangered species.
Most heroes are not super. They don’t appear in comic books, on television, or in movies. They just do what they believe needs to be done to make their world a better place. Bike Batman is one of them.
Bike Batman is a 30-year-old married engineer who lives in Seattle, Washington. He’s a cyclist who also buys and sells bikes as a hobby.
About three years ago, he was looking for a bike for his wife. He found one on Craigslist, a website where people list things they want to sell. As he often does, he also looked at Bike Index, a popular website that allows users to register their bikes and post reports when they’re taken. The bike, which he was considering purchasing, clearly matched one reported stolen on Bike Index.
Then he called the person who claimed to be the bike’s owner and arranged to meet him— supposedly to complete the sale. When the two men met, Bike Batman told the thief, “You’ve got two options. You can wait until a police officer gets here, or you can just get out of here.” You can imagine what the thief did.
After that first success, Bike Batman developed a safer routine. When he sees questionable bike ads on Craigslist, he cross-references the image with bikes reported on Bike Index. Once he has confirmed it with the owner, he arranges a meet-up with the thief and will call the Seattle police department so that officers can participate in the action. In more than half of the 22 cases in which he has got back and returned bikes, the thieves have been arrested. In one case, Bike Batman even helped a family recover a wide range of prized possessions that suspects had stolen during a home burglary.
His nickname came from a discussion with a police officer who suggested he be called “Robin Hood”. Since he wasn’t exactly stealing from the rich and giving to the poor, “Batman” seemed a better fit. The idea of a superhero punishing criminals feels pretty silly to him, but the main reason he continues his work is to keep up Seattle’s reputation as a friendly city.

A. a superhero B. a website manager
C. a Seattle citizen D. a police officer

A. contact the owner of the stolen bike B. look up the bike’s information
C. call the police department D. arrange to meet the thief

A. become famous B. help poor people
C. punish bike thieves D. build a friendly city
4.From the passage, we can learn that .
A. Bike Batman felt relieved to see the thieves arrested

C. the police failed to perform their duties
D. the thieves refused to return the bikes
