When we talk about intelligence(智力)，we do not mean the ability to get good scores on certain kinds of tests or even the ability to do well in school．By intelligence we mean a way of living and behaving(表现)，especially in a new situation．If we want to test intelligence，we need to find out how a person acts instead of how much he knows what to do．
For example，when in a new situation，an intelligent person thinks about the situation，not about himself or what might happen to him．He tries to find out all can be，and then he acts immediately and tries to do something about it．Probably he isn’t sure how it will all work out，but at least he tries．And if he cannot make things work out right，he doesn’t feel ashamed(羞愧)that he failed，he just tries to learn from his mistakes．An intelligent person，even if he is very young，has a special outlook(看法)on life，a special feeling about life，and how he fits into it．
If you look at children，you’ll see the great differences between what we call “bright” children and “non-bright” children．They are actually two different kinds of people，not just the same kind with different amount of intelligence．For example，the bright child really wants to find out about life, and he tries to get in touch with everything around him; while the unintelligent(不聪明的) child keeps more to himself and his own dream-world：he seems to have a wall between him and life in general．
【小题1】According to this passage，intelligence is the ability to_________．

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.
