13．During the teenage years，hormonal （荷尔蒙的） changes lead to physical changes like rapid muscle growth，burst in height，and weight gain in both boys and girls．Take a look at the information and height and weight charts（图表） for teens presented in this article if the question"How much should I weigh for my age and height"is bothering you．
Average Height and Weight Charts for Teens
Faster growth in kids usually can be noticed at age 8．Genetic factors also affect the physical growth of a child．So，it is perfectly normal for two kids of the same age to have different weights and heights．The following figures should be used as guidelines only．

Ideal Body Fat Percentage
Fit men have 14%-17% body fat．
Fit women have 21%-24% body fat．
Male athletes have 6%-13% body fat．
Female athletes have 14%-20% body fat．
The ideal body fat percentage varies mainly according to age，sex and the physical activity of the in-dividual．But it is a fact that some female athletes have body fat as low as  10% and some male athletes had lower than 4% body fat．So，it can be observed that other than the above mentioned factors，genetic factors also influence the body-fat ratio．
Body Mass Index （BMI）
You may use the following formula to calculate your BMI：
As per SI Units （国际单位）：BMI=mass （kg）/[height （meters）]2
Imperial （英制的） Units 1：BMI=mass （Ib．） x703/[height （in．）]2
Imperial Units 2：BMI=mass （Ib．） x 4.88/[height （ft）]2
Following conclusions can be derived from （得到） calculating the BMI：
BMI CalculatedConclusion
BMI 18.5～25Normal or ideal weight
BMI＞25Overweight
BMI＜18.5Underweight
BMI＜17.5Extremely underweight
BMI=30 or BMI＞30Obese（病态肥胖的）
BMI=40 or BMI＞40Extremely obese
25．According to the Average Height and Weight Charts for Teens，C．
A．girls keep on growing taller during the teenage years
B．girls grow faster at the end of teenager years than boys
C．girls grow faster at the beginning of teenager years than boys
D．boys'average weight is always heavier than girls'during the teenage years

分析 在青少年期间，荷尔蒙的改变会导致身体的变化，在身高和体重上都会改变，男孩和女孩的变化是不一样的．身高和体重的变化是否正常，本文给出了具体的计算方式．

解答 25．C，细节理解题，从图表For Boys 12-13岁，身高58-62inches；For Girls 12-13岁，身高60-63 inches，可知在青少年初期女孩比男孩长得快，故答案为C．
26．D，细节理解题，根据Ideal Body Fat Percentage部分所提到的Male athletes have 6%-13% body fat．Female athletes have 14%-20% body fat．从这里可看出男运动员比女运动员有更低的脂肪，故答案为D．
27．A，推理判断题，根据Body Mass Index （BMI）这一部分，BMI Calculated计算结果是BMI 18.5～25，得出结论"正常或理想的体重"；计算结果是BMI＞25，得出结论Overweight"超重"，所以可知通过计算the BMI可得出你的体重是否正常的结论，故答案为A．
28．B，推理判断题，根据Body Mass Index （BMI）中的计算方法，这个1.5米高，重68千克的男孩的BMI是体重除以身高的平方约等于30.7，根据图表中的BMI=30 or BMI＞30，说明是Obese（病态肥胖的），故答案为B．

点评 解答任务型阅读理解题，首先对原文材料迅速浏览，掌握全文的主旨大意．因为阅读理解题一般没有标题，所以，速读全文，抓住中心主旨很有必要，在速读的过程中，应尽可能多地捕获信息材料．其次，细读题材，各个击破．掌握全文的大意之后，细细阅读每篇材料后的问题，弄清每题要求后，带着问题，再回到原文中去寻找、捕获有关信息．最后，要善于抓住每段的主题句，阅读时，要有较强的针对性．对于捕获到的信息，要做认真分析，仔细推敲，理解透彻，只有这样，针对题目要求，才能做到稳、准．

6．SCS Global Services（SCS）has evaluated a new methodology for measuring the carbon sequestration（封存） ability of soil under the Verified Carbon Standard （VCS），a leading greenhouse gas （GHG） accounting system．The methodology，developed by The Earth Partners，will allow land managers who sequester GHGs in grasslands and farmlands to produce carbon credits for sale in the voluntary market．
Managers of grasslands and farmlands can increase carbon sequestration in soil by practices such as changing grazing（放牧）practices and operating treatments designed to improve the variety and productivity of plant groups．The Earth Partners is presently piloting this methodology with farmers across seven million acres of the Palouse River and Columbia Plateau regions in the Pacific Northwest．
"The VCS program has achieved an important milestone in now combining grassland and rangeland carbon offset projects，"said Dr．Robert J．Hrubes，Executive Vice President of SCS．"SCS looks forward to approving and verifying agricultural carbon offset projects that use this very powerful new methodology．"
The VM0021 Soil Carbon Quantification Methodology is based on decades of soil carbon research and testing conducted by top soil scientists．The methodology was developed by The Earth Partners and verified by Environmental Services，Inc．as well as SCS Global Services．It is the first soil carbon methodology to be approved for use under the VCS．
"This widely tested methodology is the first to specially deal with soils in a market，"said Steven I．Apfelbaum，Chairman of Applied Ecological Services，Inc．and Director of Science with The Earth Partners．According to Apfelbaum，soils represent the second largest living sink of carbon on the planet．

29．The new methodology is assessed according toB．
A．The Earth Partners　　　　        
B．the Verified Carbon Standard
C．Environmental Services，Inc．

B．changing grazing practices and operating treatments
C．reducing the variety and productivity of plant groups
D．decreasing farmlands in the Pacific Northwest
31．Which of the following is true according to the passage？A

    Last weekend we go mountain climbing．Even the heavy rain in the morning could not prevent us going．Set off very early，we went along an extreme narrow road，all in high spirits．On every side of the road was green fields and some farm houses．We could hear the sound of the rain and our footsteps mixing with our laughter．At noon we reached the top of the  mountain．That surprised us most there was the beauty of scenes．After having short rest there and sharing with the food we had brought，we started going down．It rained even harder．We were wet to the skin，and we still sang and laughed happily．

8．A woman in the US is able to speak for the first time in 11 years after a pioneering voice box transplant．
Brenda Jensen said the operation was a great success which had saved her life．Thirteen days after the surgery she said her first words，"Good morning．I want to go home．"It is the first time a voice box and windpipe（气管）have been transplanted at the same time and only the second time a voice box has ever been transplanted．
Ms．Jensen，52，had been unable to speak on her own since her voice box was damaged during surgery in 1999．Since then，she has been unable to taste or smell food，could breathe only through a hole in her windpipe and could talk only with the help of an electronic voice box．
In October，surgeons at the University of California Davis Medical Centre removed the voice box and 6cm of the windpipe from a donor body．In an 18-hour operation，this was transplanted into Ms．Jensen's throat and the team connected it to her blood supply and nerves．
Professor Martin Birchall from University College London，who was part of the surgery team，said，"We've learned that we can repair nerves to make even very complex organs function again．It'll open the door to better facial transplants and will be extremely important as tissue engineering develops．"A voice box transplant might be life changing，but it is not life saving．Everyone who receives a transplant must take drugs to control the immune system for the rest of their lives．These drugs can reduce life expectancy，so they are normally set aside for life saving procedures．One of the reasons Ms．Jensen was a suitable person for this transplant was that she was already taking immune controlling drugs after a kidney-pancreas（胰腺）transplant four years ago．Professor Peter Belafsky，part of the surgical team，said，"Brenda was an exceptional（例外的）candidate for the transplant because she was highly motivated．"Anyone who's met Brenda knows that she is a strong and determined person with a great outlook on life in spite of the many physical challenges she's faced over her lifetime．
21．The voice box transplant operation is of great significance because it proves thatB．
A．facial transplants are now easier to perform
B．nerve repairing is a breakthrough in tissue engineering
C．new medical technology is always possible to discover
D．the drugs taken after the operation help the patient live longer
22．Ms．Jensen was a suitable person for this transplant because she wasD．
A．experienced and brave　　
B．seriously ill and motivated　　
C．determined and realistic　　
D．strong-willed and prepared
23．Which of the following is the right chronological order of the event？B
a．Ms．Jensen received a voice box transplant operation．
b．Ms．Jensen began to take immune controlling drugs．
c．Doctors removed the voice box from a donor body．
d．Ms．Jensen had a kidney-pancreas transplant operation．
