Height is just one of the thousands of features your genes decide. In fact, because you have two parents, your genes provide you a height that usually lands somewhere between the height of each parent. If both your parents are tall, then most probably you will be tall, too, but if you have questions about how tall you’re going to be, ask your doctor if he or she can help you find it out.
But genes don’t decide everything. For example, eating an unhealthy diet can keep you from growing to your full potential(潛力). Getting plenty of sleep and enough exercise will help you grow to the expected height.
No doubt you’re wondering how fast you should grow. It depends. There’s no perfect or right answer. Generally speaking, kids grow about 2 inches (6 centimeters) a year between age 3 and the time when they start puberty (when your body starts changing and becoming more grown up).
Your doctor will know how your growth has been going over the years. Two centimeters here and 2 inches there are not nearly as important as the height you’re at now, how you’ve been growing up to this point, and what other changes your body may be going through.
Don’t be scared if you seem to have grown a lot in a very short time. Everyone has a growth spurt（高峰）during puberty. The age for starting puberty is about 10 for girls and about 11 for boys. But it can be earlier or later ----between 7 and 13 for girls and 9 and 15 for boys.
You’ll usually begin to notice that you’re growing faster about a year or so after your body starts to show the first changes of puberty.

Mount Kilimanjaro is the highest mountain in Africa and one of the largest free-standing mountains in the world, and some say, the most beautiful place on the earth!
The mountain towers 15,000 feet above the plains. Mount Kilimanjaro is in Tanzania and it covers an area of 60 miles long and 40 miles wide. Kilimanjaro is an extinct volcano(死火山), with 3 peaks. Kibo is the highest one in the center.
Because of Kilimanjaro’s great height, the mountain influences its own weather. Winds incoming from the Indian Ocean are stopped upward by the mountain and drop their moisture(濕氣) as rain and snow. People have planted coffee, corn, and other crops on the lower slopes(斜坡).
Mount Kilimanjaro now attracts many thousands of walkers each year. Because of a temperature rise in recent years, the beautiful snow cap of Kilimanjaro is retreating(消退)fast. A research said that the white snow on the mountain might be gone in 15 years. What a pity!

Many strong and out-of-control emotions are recognized as an illness. People who are always very sad have depression (抑郁癥); those who worry a lot have anxiety.
But what about anger problems? Anger is largely viewed as a secondary emotion – one caused by other emotions. People are thought to be angry because they are sad, anxious or stressed. In the past, many doctors didn’t accept the idea that anger could be a problem all on its own.
Today, though, a growing number of mental health experts think that anger is a serious problem that needs its own treatment.
How to tell the difference between “normal” anger and “anger problem” is difficult. After all, everyone gets really mad from time to time. Experts point out a few ways.
Disordered anger, as it is sometimes called, tends to be of greater intensity (強(qiáng)度). It takes very little to set off a person with an anger problem, and their responses (反應(yīng)) are very strong. An example: While most people would get upset if a driver cut them off, someone with disordered anger might try to chase down the car and force it off the road.
And in cases of disordered anger, the person gets angry more frequently and his/her anger lasts longer. For most people, angry feelings disappear quickly. But people with anger problems often stay angry for days, weeks or even years; their feelings of anger don’t disappear over time.
Consequences are also important to consider: Disordered anger often damages people’s lives. “It interferes (干擾) with people’s relationships and their jobs,” says Raymond Chip Tafrate, a US psychologist. “Even their health is affected.”
Anger clearly increases the risk of certain health problems, as many studies have shown. “When a person is angry, their heart beats faster and their blood pressure goes up,” says Howard Kassinove, a professor at Hofstra University in New York. Over time, these changes take their toll on the body, he adds.
Experts suggest that people with an anger problem take anger-management programs. The programs teach people to control their responses to stressful situations through the use of relaxation techniques. The programs sometimes include life-skills training as well: increasing someone’s level of competence (競(jìng)爭(zhēng))– whether on the job or as a parent or partner – helps bring down stress and cut angry feelings.
小題1:A person who _________ most possibly has disordered anger in the experts’ opinion?

A．can’t get out of anger quickly

B．is dissatisfied with relationships

C．has high blood pressure

D．is worried about his job

小題2:What does the underlined word Consequences mean?

A．Responses.

B．Effects.

C．Reasons.

D．Feelings

小題3:Which of the following is TRUE according to the passage?

A．Anger is an secondary emotion that makes people sad and stressed.

B．Anger was recognized as an illness by most doctors in the past.

C．A person with an anger problem gets angry more often and easily.

D．The use of relaxation techniques is the best way to manage anger.

小題4: What is the best title of the passage?

A．Can anger be an illness?

B．Is it disordered anger?

C．Can anger influence our life?

D．Is anger management important?

We each have a memory(記憶力). That’s why we can still remember things after a long time. Some people have very good memories and they can easily learn many things by heart, but some people can only remember things when they say or do them again and again. Many of the great men of the world have got unusual memories.
A good memory is a great help in learning a language. Everybody learns his mother language when he is a small child. He hears the sounds, remembers them and then he learns to speak. Some children are living with their parents in foreign countries. They can learn two languages as easily as one because they hear, remember and speak two languages every day. In school it is not so easy to learn a foreign language because the pupils have so little time for it, and they are busy with other subjects, too.
But your memory will become better and better when you do more and more exercises.

Qi Haoran, a Junior One student, was quite busy over the past winter vacation – and not just with homework. Qi, together with 10 other classmates made a volunteer group to call on people to join the Clean Your Plate Campaign (光盤行動(dòng)).
The 11 students went to many restaurants and told people the importance of saving food.“Excuse me, do you know that 950 million people around the world still haven’t got enough to eat? Could you please not waste food?” They would say this kind of thing hundreds of times every day.
The Clean Your Plate Campaign began on the Internet in January. It calls on people to reduce food waste.
China in these years had serious problems with wasted food. CCTV reported in January that the food Chinese people waste every year is enough to feed 200 million people for a year.
Chinese people are well known for being hospitable (好客的) and generous. Many even feel that they lose face if their guests have eaten all their food.
Luckily the campaign has got the support of many. In a restaurant in Xinjiang, the owner gives the guests who have eaten up all that they ordered a sticker. People can enjoy a free meal when they have 10 stickers. More than 750 restaurants in Beijing have begun to offer smaller dishes and encourage their guests to take leftovers(吃剩的食物) home.

Moms take care of their children life and dads bring home food and make the family rules. These are the roles moms and dads fall into when they become parents and it’s common among all cultures. But times change and parents’ roles seem to be changing, too. More women are bringing home food by having full-time jobs and men are taking care of their children at home.
Chinese TV show Where Are We Going, Dad ? provides a closer look at the changing roles of dads in modern family life. The show follows the adventures（冒險(xiǎn)經(jīng)歷）of five celebrity（明星）dads who take trips with their young children (aged 4 to 6) and try to complete a set of tasks. It shows how young dads are trying hard to find the best way to raise their children and keep a closer relationship with them. Young dads no longer want to be cold.
Psychologists（心理學(xué)家）say that a strong fatherly influence is important in a child’s development. Fathers teach their children skills and encourage them to try new things. They also give them a sense of safety. A child learns that if something goes wrong, he or she can depend on dad to help fix it. The psychologists also say that without a dad, a child is more possible to drop out of school and get into trouble.
