6.The gentle giants of our oceans are whale sharks.It's the biggest whale shark and can reach as long as 41.5feet,and these amazing creatures are not only the biggest sharks,but they are also biggest fish of any kind.
Whale sharks have a lifespan of 70years on average,and they spend their days gently swimming in the warm and tropical oceans.
Their teeth are the size of match heads,and while their jaws could be powerful,they have never tended to attack humans.Their teeth play no role in eating,as plankton does not need to be chewed.They are to be found in numbers in the warmer oceans and they prefer the deep waters of open oceans.They tend to travel alone.
Several times a year they gather together in certain spots where plankton is plentiful.Those areas are all within a 30°north or south latitude from the equator.Sadly whale sharks are targeted by commercial fisheries at those spots.
How easy it must be for those fishermen to catch those beautiful creatures who can only swim at 3.5miles per hour!So great a loss in numbers have they suffered that whale sharks are now listed as one of the endangered species.Some countries have started to take measures to protect the whale sharks from extinction.
The Philippines,India and Taiwan have all banned the fishing,selling,importing and exporting of whale sharks for commercial purposes.However,the law doesn't seem to be effective because the hunting and killing still goes on today,especially in Taiwan and the Philippines.Each whale shark can fetch around $21,000.In parts of Asia they are known as the"money shark".
The mighty dollar wins again at great cost to our habitat,and we will not know what we have lost until we have lost it forever.Therefore,it is high time for us to do something for the whale sharks.

A.usually live a life of more than 70years
B.always travel in the ocean in groups
C.depend on their teeth to harvest their food
D.live in the deep waters of warmer oceans

A.Because they swim in the oceans at a slow speed.
B.Because they are surrounded by so many fisherman.
C.Because they often gather together.
D.Because they never tend to attack humans in the water.
33.We know that in Taiwan and the Philippines,C.
A.fishermen are earning little by catching the whale sharks
B.fishermen have stopped hunting and killing the whale sharks
C.fishermen are continuing to hunt and kill the whale sharks
D.importing and exporting whale sharks is legal

分析 本文属于记叙文阅读,作者通过这篇文章向我们介绍了鲸鲨,它生活在温暖的海洋的深水水域,因其有巨大的利润而被渔民捕杀,如今已经快濒临灭绝,因此作者呼吁我们要可保护鲸鱼.

解答 31.D  细节理解题,根据第二段Whale sharks have a lifespan of 70years on average,and they spend their days gently swimming in the warm and tropical oceans.可知鲸鲨生活在温暖的海洋的深水水域,故选D.
32.A  推理判断题,根据第五段How easy it must be for those fishermen to catch those beautiful creatures who can only swim at 3.5miles per hour!So great a loss in numbers have they suffered that whale sharks are now listed as one of the endangered species.可以推测出鲸鱼鲨很容易被抓住是因为他们以一种缓慢的速度在海洋里游泳,故选A.
33.C  细节理解题,根据倒数第二段The Philippines,India and Taiwan have all banned the fishing,selling,importing and exporting of whale sharks for commercial purposes.However,the law doesn't seem to be effective because the hunting and killing still goes on today,especially in Taiwan and the Philippines.可知在台湾和菲律宾渔民们依然在继续捕杀鲸鲨,故选C.
34.D  推理判断题,根据倒数第二段Each whale shark can fetch around $21,000.In parts of Asia they are known as the"money shark".可知渔民捕杀鲸鲨是因为它们很贵,渔民可以从中获得巨大的利润,故选D.
35.A  主旨大意题,通读全文可知作者写这篇文章是为了呼吁人们保护鲸鱼,故选A.

11.Being Left-handed in a Right-handed World
The world is designed for right-handed people,but why does a tenth of the population prefer the left?(71)D
The answer to it remains a bit of a mystery.Since scientists have noticed that left-handedness tends to run in families,it's assumed that left-handedness has a genetic(基因的) component to it.
(72)A In fact,identical twins,who share the same genes,can sometimes prefer to use different hands.There are also plenty of theories on what else might determine which hand you write with,but many experts believe that it's kind of random.
Historically,the left side and left-handedness have been considered a negative thing by many cultures.(73)CIn some areas,the left hand became known as the"unclean"hand.In many religions,the right hand of God is the favored hand.For example,Jesus sits at God's right side.God's left hand,however,is the hand of judgement.Various activities and experiences become rude or even signs of bad luck when the left hand becomes involved.In some parts of Scotland,it is considered bad luck to meet a left-handed person at the start of a journey.(74)FA person giving directions will put their left hand behind them and even physically try to point with their right hand if necessary.In some Asian countries,eating with the left hand is considered impolite.
(75)G People come to realize that left-handedness is natural.People even noticed that many famous people are left-handed,including Benjamin Franklin,Leonardo Da Vinci,and Charlie Chaplin.Some researchers find out that lefties are more creative and can deal with abstract thinking better.The left-handedness is more easily adaptable to the right-handed world as well.Being left-handed is no longer a sad story now; instead,it is a wonderful gift or maybe it is something you should take pride in.

A.In other words,left-handers are born that way.
B.Left-handedness used to be regarded as a disability.
C.The unfavorable associations of the use of the left hand among cultures are varied.
D.Why do they prefer to use their left hand rather than their right hand for routine activities?
E.Why do some parents force their left-handed children to become right-handed when writing?
F.In Ghana,pointing,gesturing,giving or receiving items with the left hand is considered rude.
G.Fortunately,nowadays most societies and cultures no longer reject left-handedness like before.
1.The longer a teenager spends using electronic devices such as computers and smartphones,the worse their sleep will be,a study of nearly 10,00016-to 19-year-olds suggests.
More than two hours of screen time after school was strongly linked to both delayed and shorter sleep.Almost all the teens from Norway said they used the devices shortly before going to bed.Many said they often got less than five hours sleep a night.
The teens were asked questions about their sleep routine on weekdays and at weekends,as    well as how much screen time they clocked up outside school hours.On average,girls said they    spent around five and a half hours a day watching TV or using computers,smartphones or other    electronic devices.And boys spent slightly more time in front of a screen around six and a half hours a day,on average.Playing computer games was more popular among the boys,whereas girls were more likely to spend their time chatting online!
Any type of screen use during the day and in the hour before bedtime appeared to disturb    sleep-making it more difficult for teenagers to nod off.And the more hours they spent on these devices,the more disturbed their sleep became:When daytime screen use totalled four or more hours,teens had a 49%greater risk of taking longer than an hour to fall asleep.These teens also tended to get less than five hours of sleep per night.
Dr.Hysing said her findings had suggestions for the wider population as so many people  use these devices."We know that sufficient sleep is essential for good physical and mental health.Logging off may be one important step toward securing a good night's sleep."
Prof Rnssell Foster,an expert the University of Oxford,said,"This is an important study  as it provides practical evidence that the use of electronic devices before bed does indeed reduce sleep duration."He said teenagers should be warned of this.
28.What is stressed in the first two paragraphsB?
A.Teens now tend to have more problems with studies.
B.Teens get harder to fall asleep with more screen time.
C.Teens addicted to screen are likely to be more energetic.
D.Teens'sleep duration has nothing to do with their screen time.
29.By asking questions,the study findsC.
A.boys are more likely to chat online than girls
B.girls are more frequent on the screen than boys
C.teens are attracted by different electronic devices
D.teens use the screen for the same purpose
30.What does the phrase"nod off"in the fourth paragraph meanD?
A.shut off    B.get excited    C.focus on  D.fall asleep
31.How does Prof Russell Foster feel the studyA?
A.Beneficial.    B.Uncaring.    C.Doubtful.D.Dissatisfied.
15.Whether you live in Seattle or the Sahara desert,the time has come to invest in a good raincoat or umbrella,a new study suggests.
As global temperatures continue to rise,more"extreme rain"events-intense,cats-and-dogs downpours-can be expected,said the study,published Monda y in the journal Nature Climate Change.And that,scientists said,means an increased flood risk,particularly for the world's driest areas.The study challenges the idea that global warming is causing dry areas to become drier and wet areas wetter.
"In both wet and dry regions,we see these great increases in heavy precipitation(冰雹),"lead author Markus Donat,a climate scientist at the University of New South Wales,told Nature.
Donat and his team collected data from 1951 to 2010 on extreme precipitation events from 11,000 weather stations around the world,Nature reported.
In that time,the number of days with"extreme precipitation"increased 1 percent to 2 percent per decade.
"We found a strong relationship between global warming and an increase in rainfall,particularly in areas outside of the tropics,"Donat said in a statement.
"Importantly,this research suggests we will see these extreme rainfall events increases at regional levels in dry areas,not just as an average across the globe,"Donat added.
Peter Stott,a senior climate scientist at Met Office,told Climate Central that the study's findings are important,because more violent rainfall and flooding will"challenge our capability to adapt to a rapidly changing climate."
As Nature reported,the research aligns(结盟)with a 2015 study that found global warming has led to a sharp increase in record-breaking precipitation ev ents.Donat told Nature that his study should come as a warning to world governments.
33.Which of the following is one of the study's findings?B
A.Global warming is causing dry areas to become drier and wet areas wetter.
B.Extreme rain events can be expected at regional levels in dry areas.
C.Extreme rainfall events increase at regional levels in wet areas.
D.Rainfall increases particularly in the tropics areas.
34.Why does Scott think the findings are important?C
A.The research aligns with a 2015 study.
B.They are about extreme precipitation events.
C.They remind us to adjust to rapid climate changes.
D.The study involves many famous climate scientists.
35.The purpose of the study is toD.
A.encourage investors to start business in Seattle or the Sahara desert
B.persuade people to take a raincoat or an umbrella with them
C.challenge the previous findings of research on climate
D.warn world governments to focus on global warming.
