Race walkers are conditioned athletes.The longest track and field event at the Summer Olympics is the 50-kilometer race walk,which is about five miles longer than the marathon.But the sport’s rules require that a race walker’s knees stay straight through most of the leg swing and one foot remain in contact(接触) with the ground at all times.It’s this strange form that makes race walking such an attractive activity,however,says Jaclyn Norberg,an assistant professor of exercise science at Salem State University in Salem,Mass. Like running,race walking is physically demanding,she says.According to most calculations,race walkers moving at a pace of six miles per hour would burn about 800 calories(卡路里) per hour,which is approximately twice as many as they would burn walking,although fewer than running,which would probably burn about 1,000 or more calories per hour. However,race walking does not pound the body as much as running does,Dr Norberg says.According to her research,runners hit the ground with as much as four
times their body weight per step,while race walkers,who do not leave the ground,create only about 1.4 times their body weight with each step As a result,she says,some of the injuries associated with running,such as runner's knee,are uncommon among race walkers.But the sport's strange form does place considerable stress on the ankles and hips,so people with a history of such injuries might want to be cautious in adopting the sport.In fact,anyone wishing to try race walking should probably first consult a coach or experienced racer to learn proper technique,she says.It takes some practice. 21.Why are race walkers conditioned athletes? A.They must run long distances. B.They are qualified for the marathon C.They have to follow special rules. D.They are good at swinging their legs. 答案：C 解析：细节理解题。由文章第二段中的But the sport's rules require that a race walker's knees stay straight through most of the leg swing and one foot remain in contact with the ground at all times.”可知，竞走必须遵循特殊规则。故选C项。 22.What ad vantage does race walking have over running? A.It's more popular at the Olympics. B.It's less challenging physically. C.It's more effective in body building. D.It's less likely to cause knee injuries. 答案D 解析：细节理解题。由文章最后一段中的“.some of the injuries associated with running,such as runner's knee,are uncommon among race walkers.”可知，一些对于跑 步者常见的伤病，如膝盖受的伤，在竞走者中并不常见。故选D项。 23.What is Dr Norberg's suggestion for someone trying race walking? A.Getting experts'opinions B.Having a medical checkup. C.Hiring an experienced coach. D.Doing regular exercises. 答案A 解析：细节理解题。由文章最后一段中的In fact,anyone wishing to try race walking should probably first consult a coach or experienced racer to learn proper

D.Doing regular exercises. 答案:A 解析:细节理解题。由文章最后一段中的“In fact,anyone wishing to try race walking should probably first consult a coach or experienced racer to learn proper
technique..”可知，Dr Norberg给想尝试竞走运动的人的建议是先咨询专业人士的 意见。故选A项。 24.Which word best describes the author's attitude to race walking? A.Skeptical. B.Objective. C.Tolerant. D.Conservative. 答案B 解析：推理判断题。通读全文，作者介绍了竞走这项运动的特点：需要遵循一定规 则：膝盖较少受伤，但会对脚踝和臀部造成压力；如果想从事这项运动，尚需专业人 士指导。由此可推断，作者对待竞走的态度是客观的。故选B项。 B There are many colours in nature.But do you think that a colour has weight?I think you'll say"no".But I'm afraid you are wrong.If you don't believe it,you may do a small experiment. First,put two objects with the same weight into two boxes.Then cover the boxes.Third,wrap(;)one box with a red piece of paper,and the other one with a white piece of paper.OK.Now hold the boxes with your hand one by one.It is certain that you will think the red one is a little heavier. Why do you think so?A scientist found that different colours have different weights in man's mind.That is to say,every colour has its own weight in our minds. The scientist told us that colours also have smells.Can you smell the colour?Of course not.Then why did the scientist say so?That is because every colour stands for a kind of light with a certain wavelength().It reaches our brain through sense organs(器官). According to this discovery,scientists say that people accept the colours they like,and refuse the colours they hate.So your body and mind will be healthy by using the colours you like.Or you'll be nervous or even get ill.For example,you like blue and hate red.If you stay in a room with red windows,wallpaper and furniture for two hours,you'll feel you have been there for four hours.But if the room is blue,you'll feel you have been there for only an hour.And,if a person walks out of a blue room and into a red room,his temperature will rise.That means our body temperature will change with different colours. 25.From the experiment,we know that A.the two boxes have the same weight B.colours can change the weight of an object C.the red paper is heavier than the white paper

According to some experts,the world population will increase to 10-12 billion by the end of this century.This means that food will become very expensive and possibly,even out of reach,for billions of people
This is where 3-D printing may save the day.Anjan thinks that the only way to solve the problem will be to equip every kitchen with a 3-D printer and print out meals from tubes of powder and oil.He believes that these meals with a shelf life of over 30 years would result in less food wastage. Most important of all,it would be easier to make food from things that we now do not consider edible(可食用的).A great example of that is the protein from meat.Most experts believe that as the population grows,the supply is not going to be enough to feed everyone.Anjan believes that we could easily get the same protein from insects.Though all this futuristic food may sound unappealing,scientists believe that when faced with a terrible food crisis,it will be very welcomed. While this may sound a little difficult to believe,Anjan seems to have convinced the scientists at NASA,who are looking for a solution to feed ing astronauts when they go on really long missions,like the one being planned to Mars.They gave Anjan $125,000 to start building the first real 3-D printer that creates the food. Anjan is not the only one with this idea.A group led by Professor Hod Lipson has been experimenting with this idea since 2011 and has even succeeded in printing out cube-shaped creations from powdered milk and cookies with limited sugar!
