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 (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 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. | | 1. The Chinese for the word "puberty" is ________. | | [ ] | A. 童年时期

The Spring Festival, the most important Chinese holiday when everyone returns home, has caused headaches
for millions of Chinese. More than 2 billion people travel at the same time, making getting travel tickets and the
journey difficult. But in 28 years, Spring Festival travel may not be a problem at all. China plans to build more
than 120,000 kilometers of railway and a fast transportation network that will serve 90% of the population by
2020. And because most of China will be cities, people will not have to go to other places to find a job, so it will
no longer be a problem.

web tools through Internet. Readers can discuss topics with journalists and editors. Information will move

natural gas, solar power, nuclear power and even water can take the place of oil as sources of energy (能源).

Everything will be in the computer and students will not need to bring books to school. They will find
