Height is just one of the thousands of features 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 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(潛力). Getting plenty of sleep and enough exercise will help you grow to the expected height.
No doubt(懷疑) 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.
1.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 save the environment D. You can record your growth during puberty
2. 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
3. After reading this passage, we can explain ___________.
A. how good it is to be a doctor B. how much sleep time we need
C. why genes can’t decide everything D. what healthy diet is
4. Which is NOT mentioned in the passage?
A. Your height most probably depends on how high 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.

Short people, studies have shown , are more likely to have a stroke , suffer from high blood pressures and heart disease and be bullied in school .
Now, researchers report that short people—at least in the past—were also more likely to die at a younger age than their taller peers.
Their study, published in the Journal of Epidemiology (流行病學) and Community Health , found that short bones have something to do with short life for more than 1,000 years. The conclusion was based on 490 sets of adult skeletal(骨架) remains from an archaeological(考古學的) site in northeastern England , YC dating from the 9th century to about 1850 .
About 55% of men and 73% of women died before the age of 45, and 39% of men and 56% of women died before age 30. The risk of death before age 30 declined as bone length increased.
“This study provides evidence from an archaeological sample that long bone length is connected with age at death—those with smaller bones tend to die younger,” according to Dr. D.J. Gunnell of the university of Bristol in the UK and colleagues .
While it is not clear why short stature(身材) might be linked to earlier death , the researchers point out that height is an indicator of childhood nutrition, which may have long-lasting effect on health .
“Mechanism (身體結(jié)構(gòu)) for height-mortality(死亡) associations in the past may differ from those today , for example , short stature may have increased the risk of death in childbirth and this may explain the higher risk of premature(未成熟的) mortality in women,” Gunnell and colleagues write .
“However, short bones, it would appear, have always been a marker of a short life,” the authors conclude.
【小題1】The title of the passage should be .
A.Short people and their taller peers |

You have been badly injured in a car accident. It is necessary to give you a blood transfusion because you lost a great deal of blood in the accident. However, special care must be taken in selecting new blood for you. If the blood is too different from your own, the transfusion could kill you.
There are four basic types of blood; A, B, AB, and O. A simple test can make sure of a person's blood type. Everybody is born with one of these four types of blood. Blood type, like hair color and height, is received from parents.
The four groups must be transfused carefully. A and B cannot be mixed. A and B cannot receive AB, but AB may receive A or B. O can give to any other group; therefore, it is often called the universal donor (萬能捐贈者). For the opposite reason, AB is sometimes called the universal recipient(接受者). However, because so many reactions (反應) can happen in transfusions(輸血), patients usually receive only salt of plasma (liquid part of blood) until their blood can be matched as exactly as possible in the blood bank of a hospital. In this way, it is possible to prevent the transfusion from any bad reactions.
86. People with type A blood can receive type .
A. AB B. B C. O D. all of the three
87. If you need a blood transfusion, the best and safest blood for you is .
A. a mixture of type A and type B
B. a mixture of salt, plasma and type O
C. type AB
D. exactly the same type as your own
88. The phrase "universal recipient" means a person who .
A. can receive blood of type A or B
B. can receive blood of any other type
C. can give blood to anybody
D. cannot give blood to others
89. A good title for this article is .
A. Getting Enough Blood
B. Differences Between Blood Types
C. Man's Four Types of Blood
D. How to Give Blood Transfusion
90. Which of the following statement is NOT true?
A. Carelessness in a blood transfusion may lead to death.
B. AB is the mixture of A and B
C. AB is called the universal recipient because it can receive any other group.
D. In transfusions, patients usually receive only salt of plasma at first.
