Question

【題目】根據(jù)短文內(nèi)容，選擇正確答案。
(A)
Height is just one of the 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 them 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.
It's natural that you're wondering how fast you should grow. There's no perfect or right answer. Generally speaking, kids grow about 6 cm a year between age 3 and the time when they start puberty.
Your doctor will know how your growth has been going over the years. 2 cm here and 3 cm there make a little difference to the height you're at now. How have you been growing up to this height? What other changes may your body be going through?
Don't be amazed 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 after your body starts to show the first changes of puberty.

【解析】短文大意：身高是基因決定的特征之一，但基因不能決定一切，不健康的飲食會(huì)阻礙你長(zhǎng)高，當(dāng)然你會(huì)好奇一個(gè)人是怎么長(zhǎng)到一定高度的，一般來(lái)說(shuō)3歲之前每年會(huì)長(zhǎng)6厘米，發(fā)育高峰期的孩子也會(huì)快速長(zhǎng)高，而其他年份每年大概長(zhǎng)2到3厘米。
（1）B 細(xì)節(jié)理解題。由第一段最后一句But if you have questions about how tall you're going to be, ask your doctor if he or she can help you find them out.可知答案選B。
（2） D詞義猜測(cè)題。由第三段最后一句Generally speaking, kids grow about 6 cm a year between age 3 and the time when they start puberty. 可知，在3歲到生長(zhǎng)發(fā)育期，生長(zhǎng)速度是每年6厘米，故選D。

（4）C 推理判斷題。由第二段第一 句But genes don't decide everything. 可知答案選C。
（5）C細(xì)節(jié)理解題。根據(jù)文章中的這三個(gè)句子： "In fact, because you have two parents, your genes provide you a height that usually lands somewhere between the height of each parent." "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. "以及 "Don't be amazed if you seem to have grown a lot in a very short time. ”可知，只有C項(xiàng)沒(méi)有被提到。
