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.

Germs are always found in dirty water. When you look at dirty water under the microscope, you can see them in it.
Germs are found not only in water. They are also found in air and dust (灰尘). If you cut your finger (手指), and if some of the dust goes into the finger, it will become big and red, and you will have much pain in it. Sometimes germs will go into your body and you will have pain everywhere.

Like most English children, I learned foreign languages at school. When I made my first visit to the United States, I was sure I could have a nice and easy holiday without any language problem. But how wrong I was!

    At the American airport, I was looking for a public telephone to tell my friend Danny that I had arrived. An American asked if he could help me. "Yes," I said, '1 want to give my friend a ring."

"Well, that's nice. Are you getting married?" he asked. "No," I replied, "I just want to tell him I have arrived." "Oh," he said, "there is a phone downstairs on the first floor." "But we're on the first floor now," I said.

    "Well, I don't know what you are talking about Maybe you aren't feeling too well after your journey," he said. "Just go and wash up, and you will feel a lot better." And he went off, leaving me wondering where on earth I was: At home we wash up after a meal to get the cups and plates clean. How can I wash up at an airport?

    At last we did meet. Danny explained the misunderstanding: Americans say "to give someone a call", but we English say "to give somebody a ring". When we say "to wash your hands", they say "to wash up". And Englishmen start numbering from the ground floor so the first floor is the second for Americans.
