题目内容

  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(潜力). 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. 

1.. The Chinese for the word “puberty” is          .

   A. 童年时期          B.婴幼儿时期        C.习惯养成期        D. 生长发育期

2. If you want to know how fast and how tall you should grow, _____.

   A. you should have enough exercise   B. you can ask doctors for help

   C. you should save the environment   D. You can record your growth during puberty

3. This passage is mainly about          .

   A. how the genes work in your body           B. when is the time you grow fast

   C. why you look like your parents                D. how you grow to a certain height 

4. After reading this passage, we can explain          .

   A. how good it is to be a doctor             B. how much sleep time we need

   C. why genes can’t decide everything            D. what healthy diet is

   B. Girls’ age for starting puberty is usually earlier than that for boys’.

Height is just one of the thousands of features (特征) that 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 maybe 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 enough sleep and enough exercise will help you grow to the right height.
No doubt you’re wondering how fast you should grow. There’s no perfect or right answer. Kids grow about 2 inches (5 centimetres) 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 centimetres 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 very quick growth 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, 9 and 15 for boys.
You’ll usually begin to notice that you’re growing faster about a year after your body starts to show the first changes of puberty.

China's first moon rover (月球车), Yutu, set off from the lander(登陆车) early on December 15, several hours after the Chang'e-3 probe (探测器) soft-landed on the moon surface.

The 140 kg six-wheeled rover touched the moon surface at 4:35 a.m., leaving deep lines on the loose moon land. This was recorded by the camera on the lander and the images were sent to the earth, according to the Beijing Aerospace Control Center. After that, the rover and lander will take photos of each other and start their own science explorations.

Earlier this morning, engineers made final checks of the environment of the landing area and the situation of the probe(探测仪). Yutu, reached its solar panel (光板) and started to drive slowly to the moon at 3:10 a.m.. It took Yutu nearly a whole hour to complete the simple task.

Chang'e-3 landed at the Bay of Rainbows on the moon, at 9:11 p.m. on December 14, making China the third country in the world to carry out such a mission (执行此类任务) after the United States and Russia.

In old Chinese tales, Yutu was the white pet rabbit of Chang'e’s. The name for the rover was selected following an online survey that collected several million votes from people around the world.

The rover, 1.5 meters long with its two wings folded (折叠), 1 m in width and 1.1 m in height, is a perfect robot controlled by the command center from the earth. It will face challenges including temperature differences of more than 300℃ on the moon.

Yutu will do some research and look for natural resources (资源) for three months, while the lander will conduct an exploration at the landing place for one year. Then they will have a good rest on the moon and will not be used for a long time until China’s next probe visits the moon again.
