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.The underline word “puberty” means________ in Chinese.

Recently，a solar powered（太阳能动力的）plane took to the sky for the first time. It had passed an important test on the way to travel around the world. The plane took off from an airport in Switzerland（瑞士）at 45km an hour. It slowly rose above the fields and into the sky.
“There has never been an airplane of that kind that could fly — never an airplane so big, so light, using so little energy,” said Bertrand Piccard, a leader of the project.
During the 90-minute flight, the plane did several turns. It climbed nearly 1.6k above the countryside. Engineers plan to test a night flight before July. Then they will use the results of the tests to build a second plane. They plan to travel around the world in that plane in 2012.
The plane flies at 70 km an hour. That is faster than a bike and slower than a car. Piccard and pilot Andre Borschberg will take the plane around the world. The pilots will keep the plane in the air for up to five days at a time. We want to fly it day and night with no fuel (燃料),” Piccard saidHow long did the first flight of the solar powered plane last？
