Question

【題目】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.

Answer 1

【答案】

【1】B

【2】D

【3】D

【4】C

【解析】

試題分析：這篇短文主要講述身高是基因決定的特征之一，但是基因并不能決定一切。飲食和睡眠也會(huì)影響身高。此外，生長(zhǎng)發(fā)育期對(duì)人的生長(zhǎng)也有影響。

【1】B細(xì)節(jié)理解題。根據(jù)文章內(nèi)容“Your doctor will know how your growth has been going over the years.”的描述可知，如果想知道自己會(huì)長(zhǎng)多高，可以問(wèn)醫(yī)生。故應(yīng)選B。

【2】D詞義猜測(cè)題。根據(jù)上文 “kids grow about 6 cm a year between age 3 and the time when they start puberty”和下文“The age for starting puberty is about 10 for girls and about 11 for boys”的描述可知，這里指的是生長(zhǎng)發(fā)育期，故應(yīng)選D。

【3】D主旨大意題。根據(jù)短文描述可知，文章主要介紹的是人是怎樣長(zhǎng)高的，結(jié)合選項(xiàng)可知應(yīng)選D。

【4】C.細(xì)節(jié)理解題。根據(jù)短文的描述可知，選項(xiàng)A、B、D的敘述符合原文內(nèi)容，選項(xiàng)C說(shuō)“特征是表明男女生長(zhǎng)發(fā)育期的第一次改變是不同的”的說(shuō)法是不符合原文內(nèi)容的。故應(yīng)選C。
