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.
D.Applied Ecological Services,Inc.
30.Carbon sequestration in soil can be strengthened byB.
A.selling carbon credits in the voluntary market
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
A.The VCS program proves to be successful in carbon offset projects.
B.Many soil Carbon Methodologies have already been approved for use.
C.The new methodology has been tested in many fields including soil.
D.Soils seem to be the largest living sink of carbon on the planet.

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:
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
26.Which of the following statements about ideal body fat percentage is RIGHT?D
A.Fit men have higher body fat percentage than fit women.
B.Male athletes have higher body fat percentage than fit men.
C.Female athletes have lower body fat percentage than male athletes.
D.Male athletes have much lower body fat percentage than female athletes.
27.After calculating the BMI,you can reach the conclusion whetherA.
A.your weight is normal
B.your hormone level is normal
C.your height is right for your age
D.your body fat percentage is ideal
28.If a boy is 1.5 meters in height and weighs 68 kilograms,then he isB.
A.normal B.obese
C.extremely obese D.underweight.
