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____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.

What would you think if you saw a fish walking? Would you look again if you saw a fish climbing a tree? There is a fish that does b{#blank#}1{#/blank#} of these things. It is called the tree-climbing fish.

It is believed that a traveller to India first told about the tree-climbing fish. The fish was high up in a tree. What was the fish doing in that tree? How did it get there? The traveller thought a bird might have put it there.

The next day the traveller saw a fish come out of the water. It was h{#blank#}2{#/blank#} to believe, but up the road went the fish. It used its fins (鱼鳍) and tail to pull itself along. Then it s{#blank#}3{#/blank#} to eat some worms. After the fish ate, it walked s{#blank#}4{#/blank#} over to a tree. Up, up it climbed. 

When it got high up in the tree, it took a r{#blank#}5{#/blank#}.

The traveller was s{#blank#}6{#/blank#} to see these things and told other people about the tree-climbing fish. 

People can find the tree-climbing fish not only in India but also in the Philippines, Thailand, Pakistan, and other p{#blank#}7{#/blank#}. At one time, people saw the fish in Florida, America. Because the weather there was too terrible, it was not able to live there any longer.

All around the world, people drink tea. But tea doesn't mean the same thing to everyone. In different countries, people have different ideas about drinking tea.

People in China like to drink tea with nothing in it, and they often have it with their friends or by themselves. They have two kinds of tea—green tea and black tea. They may drink tea at any time of the day anywhere. But they don't often drink tea just before they go to bed, for tea makes them awake. In England, people like to drink tea with milk and sugar in it, and they often have it in the afternoon with their friends.

In Japan, people also like drinking tea very much. It is very popular there. They drink tea every day. They have it in a way different from that in China. Some young Japanese girls are good at making tea. They can do it beautifully.

In the USA, people drink tea at breakfast or after meals. They usually use tea bags to make their tea. Making tea with tea bags is faster and easier than making it with tea leaves in teapots.

 Hangzhou Bay Wetland Park is one of the {#blank#}1{#/blank#} we tland parks. It lies in the south bank of Hangzhou Bay. If you love quiet places, you can go there to have an {#blank#}2{#/blank#} holiday.

 Last Nauonal Day, my family {#blank#}3{#/blank#} to drive there. It took us about forty {#blank#}4{#/blank#} to get there. The lakes and trees gave us a big surprise. The air was so clean that we all felt comfortable. It is {#blank#}5{#/blank#} a great place for holiday.
