Do you like dogs? Do you know the following things about dogs?

The first pet dog

Dogs are meat-eating animals. They belonged to the family of wolves (狼) a long time ago. About 15,000 years ago, people started keeping wolves for hunting (狩猎). Over the time, the wolves began to look like dogs and they became people’s pets.

What a dog looks like

Dogs come in different sizes, colors and shapes, but they’re the same in some ways. All kinds of dogs have a set of forty-two strong teeth for eating. They have sharp claws (利爪) at the end of their feet for digging up soil (挖土) and holding onto the ground when they walk. They have very good eyesight(视力). They also have high ability (能力) to hear and smell.

How a dog grows

A mother dog gives birth to one to twelve babies at a time. New-born baby dogs cannot see or hear until they are two weeks old. The mother dog gives the baby dogs milk. When they are four weeks old, they start eating soft food. When they’re eight weeks, the baby dogs have very strong legs and they can go for long walks.

How to read a dog’s feelings

Dogs act differently when they have different feelings. When a dog is angry, it opens its mouth and shows its teeth. When a dog is frightened, it lowers its ears and holds its tail (尾巴) between its legs. A happy dog always wags (摇摆) its tail.

  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.

   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
