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 (潛力). 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.
【小題1】The Chinese for the underlined word in the third paragraph “puberty” is           .

A．童年時期B．嬰幼兒時期C．習慣養(yǎng)成期D．青春期
【小題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 protect the environment
D．you can record your growth during puberty
【小題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
【小題4】After reading this passage, we can explain ___________.   
A．how good it is to be a doctor
B．how much sleep we need
C．why genes can’t decide everything
D．what an unhealthy diet is
【小題5】Which is NOT mentioned (提及) in the passage?
A．Your height most probably depends on (取決于) how tall your parents are.
B．Girls’ age for starting puberty is usually earlier than that for boys’.
C．The time showing the first changes of puberty is never noticed.
D．You may be scared sometimes when you grow too fast.

Many companies use guards and expensive alarm systems to protect their property(財產(chǎn))。 Soon a new kind of protection will be used- robots. Engineers have been working on the first mobile robots for businesses. The robots will patrol(巡邏) factories, warehoues(倉庫)，and museums at night.
The mobile robots will move around slowly on wheels. They will be able to detect people through walls and pick up sounds, such as breaking glass. They can be fixed with lound sirens(警笛) to frighten thieves, or radios to signal police or guards.
To protect a building, a robot will have to move around without knocking into the walls. Information about the building will have to be stored in the robot’s small, built-in computer. A floor map could be programmed into the computer’s memory, for example.
A mobile robot will not be able to do everything. Unlike human guards, it will not be able to climb stairs, open doors, or move along rough ground. It won’t be able to tell the difference between friends and enemies. Because of that, people will have to be barred from the area it patrols.
One kind of mobile robot will be able to “sense” whether a chair or box has been moved and go around it. This robot will also judge size well enough so that it won’t send an alam if a cat crosses the room. And if someone tries to steal this robot, it will sound a loud, painful siren. The three-foot-tall robot will be hard to steal anyway. It will weigh about 200 pounds.
U.S companies pay almost $10 billion a year to protect their property with alarm systems and human guards. Mobile robots may be cheaper.
【小題1】Why is the new kind of robots called mobile robots?

A．Because they are able to climb stairs.B．Because they are able to send an alarm

A．From a human guard .B．From a built- in computer.
C．From another robot .D．From radio signals.
【小題3】 What does the underlined word barred mean?
A．protectedB．a(chǎn)llowed .C．markedD．prevented

A．sense whether something has been moved.B．sense a cat crossing the room.
