Height is just one of the thousands of features your genes (基因) 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. 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 (潜力). Getting plenty of sleep and enough exercise will help you grow to the expected height.

No doubt(怀疑) you’re wondering how fast you should grow. It depends. There’s no perfect(完美的) or right answer. Generally speaking, kids grow about two inches (six centimeters) a year between age three and the time when they start puberty.

Your doctor will know how your growth has been going over the year. Two centimeters here and two 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 changers your body may be going through.

Don’t be nervous 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 7and 13 for girls and 9and 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.

1.The underline word “puberty” means________ in Chinese.

A. 童年时期B. 婴幼儿时期

C. 习惯养成期D. 生长发育期

A. you should have enough exercise

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 Kilimanjaros great height(高度), the mountain influences its own weather. Winds coming from the Indian Ocean are stopped upward by the mountain and drop their moisture(湿气) 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 growth 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!
