Facts about fevers
You wake up one morning, and your head feels like burning. Right away, you think, “Oh, no! I have a fever!” However, when you take your temperature, you see that it's only 37.2.1. Or, do you? From the standards in use for a long time, a fever starts at 38. Some doctors now don't agree with that, though. 2.It's the same for normal body temperatures.
They argue that everyone's normal body temperature isn't 37℃. It's 36.6 to 38℃ for kids and 36.1 to 37.2℃ for adults.3. Besides, people's body temperatures don't stay the same all the time.
When your body temperature is around 38℃, you have a fever.4.Fevers show that the body is doing its job. It's fighting the bad viruses and bacteria in your body. The body attacks them by turning up the heat. That way, it's harder for the viruses and bacteria to make copies of themselves. When their numbers decrease, the fever does, too.
5.So, let them do their jobs and don't treat them. Instead, try to find the cause and treat that. If the fever reaches 39.4C or higher, call your doctor. Do the same if the fever lasts longer than three days. Fevers fight to protect us, so they're our friends, not our enemies.
A.It means you have a fever.
B.Mild fevers don't last long.
C.So, you don't have a fever.
D.Fever does great harm to your body.
E.Women also have a higher number than men.
F.Many people think it's a bad thing, but it's not.
G.They feel our ideas about fevers are wrong and too old.

You finish a workout and feel great. Then you get up the next morning and your exercised muscles feel sore. You find it hard to lift your arms and brush your teeth, or bend down to pick up a book. What has happened?
Scientists call this soreness 24 to 48 hours after your exercise “delayed onset (延迟发作) of muscle soreness”, or DOMS. It is caused by microscopic damage to muscle fibers, which releases chemicals. The chemicals irritate (刺激) nerve fibers and cause pain.
Muscle soreness is a good sign. It means that you have challenged your muscles and are getting stronger. Everyone experiences it, even the best athletes. But it can be avoided by using the right exercise methods. Here are some tips:
* Warm up before you work out. This is helpful to avoid muscle soreness, but more importantly to avoid injury. It starts circulation to the muscles and warms the muscles and tendons, getting them ready for exercise.
* Stretch after your workout. After exercising, make sure you stretch your muscles for 15 to 20 seconds before they cool down. They will be warm and elastic (弹性的) so they will stretch well.
* Don’t do too much too soon. Whether it’s jogging, running, whatever workout routine you are starting, just do half of the exercise volume the first week to introduce your muscles to the exercises.
If you are already feeling muscles soreness, here are some ways to help relieve it.
* Get a massage (按摩). Lightly massage the sore muscle and gradually increase the depth of the massage. It might be painful in the beginning but it will gradually ease the muscle soreness.
* Take a hot bath. Nothing beats a long soak in a hot bath for muscle soreness. The heat will increase circulation and provide a soothing (舒缓) effect.
* Flush your muscles. Run hot (as hot as you can bear) water over the sore muscles for two minutes and then immediately switch to cold water for 30 seconds. Repeat this process five times. This has the effect of opening and closing your blood vessels (血管). It will flush the acid (酸物质) from them and ease the soreness.
* Exercise gently. Go for a slow walk and breathe deeply. This helps reduce muscle soreness by increasing blood flow to the sore muscles.

Tears came into this mother’s eyes when she talked about waking up her son. Every morning, her ten-year-old boy puts up one finger with his eyes still closed, begging for one more minute to sleep.
Why is he so sleepy? Because, like thousands of student “early birds” in China, he has to get up before 6 a.m. every morning.
School students usually need eight to ten hours’ sleep a night. But in Shanghai, it’s reported that 90% of the students do not get enough sleep. And studies show that without a good night’s sleep, students seem to be weaker than they should be. Many become near-sighted as a result.

When I wake up on summer mornings, I know I am going to my favorite place to volunteer and make a difference in someone's life just by being with him or her -- a summer school for autistic (患孤独症的)children.
By helping the kids read or do math, I am not only teaching important skills but also helping them feel like any other kid. There are many wrong ideas about autism. The kids I work with can think and feel. They need help only in certain areas.
Of course, each kid is special. For example, some kids like to draw, and others like to sing.
At the school, the kids learn through about 20 activities. These activities can help them learn skills they will need later in life.
The very first day I volunteered, a boy came up to me, put his hand on my shoulder, and said “Hello”. From then on, I knew I could make a difference.
Another boy loved to have me read books that can help him learn to read. Sometimes he could be encouraged to read a few words or sentences. Finally, one day during reading practice, he read nearly 220 words himself!
Summer school is also a time for fun, Last summer, bagpipe(风箱)players came to perform. Most of us had our hands over our ears because they were so loud. When they asked for a volunteer from the audience, one girl raised her hand as high as she could, got up on stage, and even tried the bagpipes in front of everyone.
Through these experiences, I realize that the challenges these kids face do not stop them from doing many amazing things. I'm teaching them, but they are teaching me more.
1.According to Paragraph 2, many people think autistic kids _________ .
A. can't read or do math B. don't have important skills
C. don’t play with other kids D. can't think or feel
2.The phrase “these experiences” in the last paragraph refers to the following EXCEPT ________ .
A. “I” read the books for kids
B. a boy read nearly 220 words himself

3.What does the author mainly talk about in the passage?

You wake up in the morning, the day is beautiful and the plans for the day are what you have been looking forward to for a long time. Then the telephone rings, you say hello, and the drama starts. The person on the other end has a depressing tone in his voice as he starts to tell you how terrible his morning is and that there is nothing to look forward to. You are still in a wonderful mood? Impossible!
Communicating with negative people can wash out your happiness. It may not change what you think, but communicating long enough with them will make you feel depressed for a moment or a long time.
Life brings ups and downs, but some people are stuck in the wrong idea that life has no happiness to offer. They only feel glad when they make others feel bad. No wonder they can hardly win others’ pity or respect.
When you communicate with positive people, your spirit stays happy and therefore more positive things are attracted. When the dagger（匕首） of a negative person is put in you, you feel the heavy feeling that all in all, brings you down.
Sometimes we have no choice but to communicate with negative people. This could be a co-worker, or a relative. In this case, say what needs to be said as little as possible. Sometimes it feels good to let out your anger back to the negative person, but all this is to lower you to that same negative level and they won’t feel ashamed of themselves about that.
Negativity often affects happiness without even being realized. The negative words of another at the start of the day can cling to（附着） you throughout the rest of your day, which makes you feel bad and steals your happiness. Life is too short to feel negative. Stay positive and avoid negativity as much as possible.
1.The purpose of the first paragraph is to __________.
A. make a comparison B. offer an evidence
C. introduce a topic D. describe a daily scene
2.How can negative people have effect on us?
A. By changing our ways of thinking
B. By telling us the nature of life
C. By influencing our emotion
D. By comparing their attitudes to life with ours
3.According to the passage, to reduce negative people’s influence on us, we are advised to __________.
A. show our dissatisfaction to negative people
B. communicate with negative people as little as possible
C. change negative people’s attitudes to life
D. make negative people feel ashamed of themselves
