19.Researchers say bedtime rules may improve a child's development.A new study found better results in four-year-olds who go to bed around the same time every night and sleep at least eleven hours.Getting less than that caused lower abilities(能力)in language,reading and early math skills.
Researchers studied about eight thousand children whose parents took part in the research on early childhood.The parents answered questions by telephones by telephone at nine months and again at four years.
Researcher Erika Gaylor asked parents to follow routines(慣例)like reading books or telling stories to their children.Children who go to bed after nine o'clock took longer to fall asleep and slept less.Children also got less sleep if they did not have bedtime routines.
Another study found that more sleep may even make a person run faster.The study was small-seven players in the Stanford University team.For the study,they had at least ten hours of sleep each night during the season.After seven to eight weeks of more sleep,the players ran faster in short training races.They also felt less sleepy during the day.
Stanford sleep researcher Cheri Mah says sleep should be part of a player's training program.This is some of her advice:Adults should try to get seven to eight hours of sleep a night.Teenagers and young adults should get nine hours or more.Go to bed and wake up at the same time every day.And short naps(打盹)during the day to get more sleep.

67.According to Erika Gaylor,what can help children fall asleep?B
A.Going to bed after nine o'clock.
B.Doing different things at bedtime.
C.Doing the same things at bedtime.
68.What does the underlined word "that" in the first paragraph refer to(指的是…)?B
A.A bedtime rule.B.Eleven hours'sleep   C.The same time every night
69.Which of the following is true?C
A.Football players need less sleep than other players.
B.Football players need more sleep than other players.
C.More sleep can make football players do better in short races.
70.Cheri Mah's suggestion isB.
A.a(chǎn)dults should sleep at leas eight hours a night.
B.we should take naps during the day to get more sleep.
C.teenagers and young adults should sleep at most eight hours a night.

7.The bicycle is one of the simplest and most useful inventions in the world.What is the most surprising is that it was not invented earlier,although the great inventor Leonardo da Vinci had drawn pictures for bicycles and also for flying machines and some other things.Those things were not produced until long after he died.
A person riding a bicycle uses very little energy to make the bicycle move,and there is no pollution at all when you are riding.In Chengdu,a lot of people rode bicycles to work twenty years ago.But cars instead of them now.Even so in developed countries,most people do not travel to work by bicycle.It is not because the bicycles are expensive or people feel tired if they ride to work.It is because the number of cars on the roads is becoming larger.It certainly becomes more dangerous to ride a bicycle.As a result,more people put their bicycles away and go to work in their cars.And in this way,the traffic is very crowded when people go to work by car in the morning and go home after work,the situation is becoming worse and worse.
Perhaps the best way to make riding safer and more popular is to create paths only for bicycles,and to make it so difficult and expensive for drivers to take their cars into the city that they will go back to use their bicycles.There has been a special way for bicycles on the road in Chengdu now.I think more and more people will return to ride bicycles to go to work.The air of cities will be much fresher.The sky will be a lot bluer.The people will live much happier lives.

54.Who invented the bicycle?C
A.GergyBush.
B.Mark.

B.Because it's very tiring to ride a bicycle.

4.The Earth has warmed by about half a degree(0.5°C) over the last 100years.It could be getting warmer on its own,but many scientists think that people are making the Earth warmer by making a greenhouse effect(溫室效應(yīng)).The greenhouse effect is important.Without it,the Earth would not be warm enough for us to live on.But just a little warmer than it is now could cause(引起)problems for humans,plants and animals.
Many of the things we do every day can change the Earth's temperature by sending greenhouse gases(廢氣)into the air.We send greenhouse gases into the air when we watch TV,turn on lights,dry hair,play video games,wash or dry our clothes or drive cars.The rubbish (waste) from factories and homes also produces greenhouse gases.
Even a small change in temperature can affect (影響)our weather.This can cause changes in the sea levels,the air,flooding,and our fresh water.
The change in the temperature can also cause changes in the living places for animals and plants,endangering many animals.
Global warming(全球變暖)is a big problem,and every little bit we do can help.We can save electricity.We can save energy in other ways such as by taking buses or walking rather than driving cars.We can recycle to reduce the rubbish and save natural resources such as trees,oil and metals.We can buy products that don't do bad to the environment and we can turn to solar energy.Remember the little bit that you do will bring a better world.

根據(jù)短文內(nèi)容,選擇最佳答案.
