第二节（共5小题；每小题2分，满分10分）
根据短文内容，从短文后的选项中选出能填入空白处的最佳选项，并在答案卡36—40 将该项涂黑。选项中有两项为多余项。
If you think you’ve gained too much weight or are too skinny, you can talk to a doctor. Your doctor will tell you ______36________.
If it is concerned about your height, weight, or BMI (体重指数), your doctor may ask questions _______37. _______. Your doctor may also ask about your family background to find out if you’ve received something from your parents that might make you taller, shorter, or a late bloomer (someone who develops later than other people of the same age). The doctor can then put all the information together to decide ______38_______.
If your weight isn’t in a healthy range, you will probably get specific diet and exercise recommendations based on your individual needs. Following a doctor’s or dietitian’s plan designed especially for you will work much better than following fad (时尚) diets. For teens, fad diets or starvation plans can actually slow down growth, and the weight loss usually doesn’t last.
What ______39________? Most teens who weigh less than other teens of their age are just fine. They may be going through puberty on a different schedule than kids of the same age, and their bodies may be growing and changing at a different rate. Most underweight teens catch up in weight as they finish puberty during their later teen years so there’s rarely a need to try to gain weight.
In a few cases, teenagers can be underweight because of a health problem that needs treat 000㈰ ㈀琀彞开 ࠀ开开ഀഀഀഀ ഀ甀瀀㜀 ㈀ 㘀瘀홑蝎䡥㉨ ㈀ 㤀㌀ 㤀 ㈀㤀 㜀 㔀㌀欀最⼀戀䘀㜀戀洀䰀刀夀椀娀眀㈀挀䄀氀䈀㘀洀䬀漀⬀㠀刀洀㘀吀䠀䈀椀㤀渀栀眀欀㐀搀㔀唀倀㜀唀稀㜀挀䈀挀爀欀圀㈀砀㜀椀唀䠀䤀焀㌀⼀漀䄀戀戀㤀㌀昀㔀㔀㜀 ㌀挀搀挀㐀㔀挀㐀㠀㐀㌀㈀㐀挀㠀戀搀㌀㐀㐀昀㔀 䜀䧍 가騀唀尀㯽댁 ĀϨ 㰀 ⠁ 儀Ā ﶷĻ궳 대 ¯ ܀ ꀀP Ӏࠌ őőŭljȹɑʗˁ̧̧̧̟́́́́̋͏͡͡͡͡͡͡͡͡͡͡͡͡Ρ项目开仪式主持发言稿.doc项目开仪式主持发言稿.doc2021-9\30\be7cc268-07e1-4a7c-a220-c658562de634Xv/dXBxLQKSMkCjWvhCWDoLYakqWYBCmnB0sKY1Whca9VIxyVAtYqw==项目,仪式,主持,发言稿https://www.wenkunet.com/FileRoot2/F:\WenkunetFileRoot1\afc753a8e403ed650a4c3fef45b6f2bcup7100002000006其他文案20210930191029304153,,,aspose345b733d32979e6766d1c66ea417430f e6766d1c66ea417430f ÿ Ā( 鵑 뜀㯽댁 Ȁ Ā 궳 꼠

5．（2014年云南省，第17题6分）将油箱注满k升油后，轿车科行驶的总路程S（单位：千米）与平均耗油量a（单位：升/千米）之间是反比例函数关系S=（k是常数，k≠0）．已知某轿车油箱注满油后，以平均耗油量为每千米耗油升的速度行驶，可行驶700千米．
（1）求该轿车可行驶的总路程S与平均耗油量a之间的函数解析式（关系式）；
（2）当平均耗油量为升/千米时，该轿车可以行驶多少千米？
考点： 反比例函数的应用．

（2）将a代入求得的函数的解析式即可求得s的值．[来源:学|科|网Z|X|X|K]
解答： 解：（1）由题意得：a，s=700，
代入反比例函数关系S=中，
解得：k=sa=70，
所以函数关系式为：s=；
（2）将a代入s=得：s===875千米，
故该轿车可以行驶多875米；
点评： 本题考查了反比例函数的应用，解题的关键是从实际问题中抽象出反比例函数模型．
6．（2014•舟山，第22题10分）实验数据显示，一般成人喝半斤低度白酒后，小时内其血液中酒精含量y（毫克/百毫升）与时间x（时）的关系可近似地用二次函数y=﹣200x2+400x刻画；小时后（包括小时）y与x可近似地用反比例函数y=（k＞0）刻画（如图所示）．
（1）根据上述数学模型计算：
①喝酒后几时血液中的酒精含量达到最大值？最大值为多少？
②当x=5时，y=45，求k的值．
（2）按国家规定，车辆驾驶人员血液中的酒精含量大于或等于20毫克/百毫升时属于“酒后驾驶”，不能驾车上路．参照上述数学模型，假设某驾驶员晚上20：00在家喝完半斤低度白酒，第二天早上7：00能否驾车去上班？请说明理由．
考点：
二次函数的应用；反比例函数的应用
分析：
（1）①利用y=﹣200x2+400x=﹣200（x﹣1）2+200确定最大值；
②直接利用待定系数法求反比例函数解析式即可；
（2）求出x=11时，y的值，进而得出能否驾车去上班．
解答：
解：（1）①y=﹣200x2+400x=﹣200（x﹣1）2+200，
∴喝酒后1时血液中的酒精含量达到最大值，最大值为200（毫克/百毫升）；
②∵当x=5时，y=45，y=（k＞0），
∴k=xy=455=225；
（2）不能驾车上班；
理由：∵晚上20：00到第二天早上7：00，一共有11小时，
∴将x=11代入y=，则y=＞20，
∴第二天早上7：00不能驾车去上班．
点评：
此题主要考查了反比例函数与二次函数综合应用，根据图象得出正确信息是解题关键．
7.（2014•襄阳，第22题6分）如图，一次函数y1=﹣x+2的图象与反比例函数y2=的图象相交于A，B两点，与x轴相交于点C．已知tan∠BOC=，点B的坐标为（m，n）．
（1）求反比例函数的解析式；
（2）请直接写出当x＜m时，y2的取值范围．
考点：
反比例函数与一次函数的交点问题
专题：
计算题．
分析：
（1）作BD⊥x轴于D，如图，在Rt△OBD中，根据正切的定义得到tan∠BOC==，则=，即m=﹣2n，再把点B（m，n）代入y1=﹣x+2得n=﹣m+2，然后解关于m、n的方程组得到n=﹣2，m=4，即B点坐标为（4，﹣2），再把B（4，﹣2）代入y2=可计算出k=﹣8，所以反比例函数解析式为y2=﹣；
（2）观察函数图象得到当x＜4，y2的取值范围为y2＞0或y2＜﹣2．
解答：
解：（1）作BD⊥x轴于D，如图，
在Rt△OBD中，tan∠BOC==，
∴=，即m=﹣2n，
把点B（m，n）代入y1=﹣x+2得n=﹣m+2，
∴n=2n+2，解得n=﹣2，
∴m=4，
∴B点坐标为（4，﹣2），
把B（4，﹣2）代入y2=得k=4（﹣2）=﹣8，
∴反比例函数解析式为y2=﹣；
（2）当x＜4，y2的取值范围为y2＞0或y2＜﹣2．
点评：
本题考查了反比例函数与一次函数的交点问题：反比例函数与一次函数图象的交点坐标满足两函数解析式．也考查了待定系数法求函数解析式以及观察函数图象的能力．
8．（2014•四川自贡，第22题12分）如图，一次函数y=kx+b与反比例函数的图象交于A（m，6），B（3，n）两点．
（1）求一次函数的解析式；
（2）根据图象直接写出的x的取值范围；
（3）求△AOB的面积．
考点：
反比例函数与一次函数的交点问题
专题：

Every 30 seconds there is an earthquake. But dont worry because most are so weak that they cannot be felt. Only a few big ones hurt people. Many earthquakes happened in China, such as the big one in Sichuan in 2008. Thousands of people died in it. So its important to know what to do when one hits. Here are some tips on how to stay safe in an earthquake.
1. If you are indoors during an earthquake, hide under a desk. Stay away from windows and anything that couldfall on you.
2. If you are outdoors, move to a clear place. Try to be away from trees, signs, buildings and streetlights. These could fall on you.
3. If you are in a shop and far from the door, dont try to run outside and rushfor exits (出口). Everyone willbe doing that and youll find it hard getting out. Dont get into a lift during an earthquake. Just hide under some strong cover near you.
