12.You may picture firefighters holding a hose (水管) outside of a burning building,but the Golden Eagles Hotshots don't fight fires quite that way.When they go into action,you may not even see a fire truck.
The Hotshots are firefighters who battle fires in wildness areas.But don't think you'll only find them in their home state California.Wherever there is a national wildfire emergency,the Golden Eagles Hotshots could be there.
But these firefighters don't work the same way as firefighters in a big city.They work in areas where there are a large number of trees,bushes,and grass.They climb up and down steep hills to clear brush and burnable debris(殘。甌hey sometimes use water,but they often fight fire with fire!
They do that by lighting what are called"backfires,"which are small,controlled fires that burn up fuel in the path of large wildfires.That way,when the wildfire gets there,it has nothing to burn and nowhere to go,because all the burnable fuel has already gone up in smoke.
The Hotshots also clear away fuel using old-fashioned hard work.For example,they use a saw to cut away trees and heavy brush that could catch fire.
Of course there are times when the Golden Eagles Hotshots do have trucks to supply water to the fires.But the water is limited,and these guys have to rely on hard work more than anything.Physical fitness is very important.They have to be in great physical shape to handle steep hills and difficult terrain(地形) while carrying a 60-pound pack.
The Golden Eagles Hotshots definitely work hard for their pay.But thanks to their efforts,many lives have been saved,many houses have not burned,and countless trees are still standing.
67.The firefighters mentioned in the passenger.D
A.do much of their work in California
B.a(chǎn)void climbing steep hills in their work
C.do their work equipped with advanced tools.
D.carry out their work mostly in forests and mountains.
68.According to the passage,why do the firefighters light"backfires"?D
A.To signal for help.
B.To remove obstacles.
C.To protect trees and bushes.
D.To prevent the fire from spreading.
69.What can we learn about the Golden Eagles Hotshots?B
A.They are firefighters working in big cities.
B.Their work requires physical strength.
C.They are voluntary firefighters working for free.
D.They usually hold a hose to put out the fires.
70.What is the author's attitude towards the Golden Eagles Hotshots?A
A.Appreciative 
B.Doubtful 
C.Worried 
D.Critical.

解答 67-70.DDBA
67題答案:D考查細(xì)節(jié)推理,根據(jù)文章第三段的They work in areas where there are a large number of trees,bushes,and grass.They climb up and down steep hills to clear brush and burnable debris(殘。麄冊谟泻芏鄻、叢林和草地的地方工作.他們在陡峭的山上爬上爬下去清理可燃的殘骸.可知本題答案為D選項(xiàng).
68題答案:D考查細(xì)節(jié)推理,根據(jù)文中的That way,when the wildfire gets there,it has nothing to burn and nowhere to go,because all the burnable fuel has already gone up in smoke.那樣的話,當(dāng)夜火到達(dá)那里的時(shí)候,它就沒東西可燒而且無處可走,因?yàn)樗械目扇既剂弦呀?jīng)以煙的形式消耗了.可知消防員點(diǎn)著backfires的目的是為了"阻止火蔓延",故本題答案為D選項(xiàng).
69題答案:B考查細(xì)節(jié)推理,根據(jù)文章倒數(shù)第二段的They have to be in great physical shape to handle steep hills and difficult terrain(地形) while carrying a 60-pound pack.他們不得不有很好的身體狀況來在背負(fù)一個(gè)重達(dá)60磅的背包下處理陡峭的山和復(fù)雜的地形.可知本題答案為B選項(xiàng).
70題答案:A考查細(xì)節(jié)推理,根據(jù)文章最后一句的But thanks to their efforts,many lives have been saved,many houses have not burned,and countless trees are still standing.但是感謝他們的努力付出,許多的生命得到了挽救,很多的房子避免了燒毀,而且無數(shù)的樹木還在林立.可知作者對于這些消防員是"感激的",故本題答案為A選項(xiàng).

點(diǎn)評 本文是一篇科教類閱讀,題目涉及多道細(xì)節(jié)理解題,做題時(shí)結(jié)合原文和題目有針對 性找出相關(guān)語句進(jìn)行仔細(xì)分析,結(jié)合選項(xiàng)選出正確答案.推理判斷也是要在抓住關(guān)鍵句子的基礎(chǔ)上合理的分析才能得出正確的答案.

12.Many students have to live with roommates while going to school or university.Having a roommate can be one of the best experiences,or easily one ofthe worst. (36)E
Follow these five tips to avoid the common mistakes that make good roommate relationships worse.
Talk things out.  (37)B  If something happens,sit down with your roommates and have a face-to-face conversation.Complaining about your roommates behind their backs creates nothing but awkward situations and general unhappiness.
(38)A  Some roommates become the best of friends,and some don't.Don't put pressure on yourself or your roommate to reach this level,especially when you first meet.Remember,you are trying to make a new friend,not scare your roommate away.And if your roommate doesn't end up being your best friend,there is no need to worry about it.
Clean up after yourself.Or at least,keep your mess on your side.  (39)C  But being considerate with where you put your own stuff will help you avoid the arguments.
Ask before you take.This applies to food,clothes,supplies and anything else that you don't own.(40)G Even if you both agree to share everything you should still ask.

A.Don't expect to be best friends.
B.Communication is of vital importance.
C.You don't need to keep the room clean and organized all the time.
D.Rooms can be really easy for a mess to pile up.
E.If you want to have a good relationship with your roommate,it all starts with you.
F.Not all roommates can become your best friends.

13.[1]A new study by the scientists at Pennsylvania State University,finds that children who take a nap(小睡) when they are 4 and 5 years old,are less likely to be hyperactive (活動(dòng)過度的) or experience depression (抑郁).
[2]The results of the study showed that kids between the ages of 4 and 5 years,who discontinued to take daytime naps,showed higher levels of hyperactivity,anxiety and depression,compared to their fellow kids who _________ at this point of their lives.In their research,the researchers were happy to show the importance of taking naps for perfect daytime functioning in young kids.
[3]It all depends on every individual case when children are ready not to take naps any more,said an author of die study,Dr.Brian Crosby,doctor of psychology at Pennsylvania State University.Dr.Crosby suggested that parents include a quiet"rest"time in the daily schedule of their children to allow kids to nap if needed.
[4]For the study purposes,the experts gathered data from 62 children between the ages of 4 and 5 years.All the kids were classified as either ones who took naps-7 percent,or the ones who did not take naps-23 percent,based on actigraphy(體動(dòng)記錄儀) data.Actigraphy data for each child who took part in the study,was collected continuously for 7 days to 14 days.Parents and caregivers were asked to provide information on their child's typical weekday and weekend bedtime and rise time,as well as their napping patterns,and also had to complete a behavioral assessment of the child.
[5]Dr.Crosby hopes that the new findings will encourage other researchers to study the ways in which napping influences daytime performances in children.
76.What's the result of the new study?(no more than 20 words)Children taking naps are less likely to be hyperactive or experience depression.
77.Fill in the blank in Paragraph 2 with words to complete the sentence.(no more than 5 words)take a nap
78.Which sentence in the text is the closest in meaning to the following one?
To the delight of the researchers,they found in the study napping was important for children's wonderful daytime performances.In their research,the researchers were happy to show the importance of taking naps for perfect daytime functioning in young kids.
79.What suggestion can parents get from Dr.Crosby according to Paragraph 3?(no more than 15 words)schedule of their children to allow kids to nap if needed
80.Translate the underlined sentence into Chinese.Dr.Crosby 希望這個(gè)新的發(fā)現(xiàn)將能夠鼓勵(lì)其他研究人員研究午睡是如何影響孩子白天的表現(xiàn)..
