2．Are you sometimes a little tired and sleepy in the early afternoon？Many people feel this way after lunch．They may think that eating lunch is the cause of the sleepiness．Or，in summer，they may think it is the heat．However，the real reason lies inside their bodies．At that time-about eight hours after you wake up-your body temperature goes down．This is what makes you slow down and feel sleepy．Scientists have tested sleep habits in experiments where there was no night or day．The people in these experiments almost always followed a similar sleeping pattern （模式）．They slept for one long period and then for one short period about eight hours later．
In many parts of the world，people take naps（小睡） in the middle of the day．This is especially true in warmer climates，where the heat makes work difficult in the early afternoon．Researchers are now saying that naps are good for everyone in any climate．A daily nap gives one a more rested body and mind and therefore is good for health in general．In countries where naps are traditional，people often suffer less from problems such as heart disease．
Many working people，unfortunately，have no time to take naps．Though doctors may advise taking naps，employers do not allow it!If you do have the chance，however，here are a few tips about making the most of your nap．Remember that the best time to take a nap is about eight hours after you get up．A short sleep too late in the day may only make you feel more tired and sleepy afterward．This can also happen if you sleep for too long．If you do not have enough time，try a short nap-even ten minutes of sleep can be helpful．
60．Why do people feel sleepy in the early afternoon according to the text？C
A．They eat too much for lunch．
B．They sleep too little at night．
C．Their body temperature becomes lower．
D．The weather becomes a lot warmer．
61．If you get up at 6：30 am，what is the best time for you to take a nap？D
A．About 12：30 pm
B．About 1：30 pm．
C．About 3：30 pm
D．About 2：30 pm
62．What would be the best title for the text？B
A．Just for a Rest
B．All for a Nap
C．A Special Sleep Pattern
D．Taking Naps in Warmer Climate．

10．What problems do you have in you study？Do you want to improve the way your study？Do you feel nervous before a test？Many students say that a lack of concentration is their biggest problem．It seriously affects their ability to study，so do their test results．
    If so，use these tips to help you．
    Study Techniques
    You should always study in the same place．You shouldn't sit in a position that you use for another purpose．For example，when you sit on a sofa to study，your brain will think it is time to relax．Do not watch TV while you are studying．Experts warn that your concentration may be reduced by 50 percent if you attempt to study in this way．Always try to have a white wall in front of you，so there is nothing to distract you．Before sitting down to study，gather together all the equipment you need．Apart from your textbooks，pens，pencils and knives，make sure you have a dictionary．If your study desk or table is needed when you are not studying，store all your equipment in a box beside it．
Your eyes will become tired if you try to read a text which is on a flat surface．Position your book at an angle of 30 degrees．
Be realistic and don't try to complete too much in one study period．Finish one thing before beginning another．If you need a break，get up and walk around for a few minutes，but try not to telephone a friend or have something to eat．
Test-taking Skills
    All your hard work will be for nothing if you are too nervous to take your test．Getting plenty of rest is very important．This means：do not study all night before your test!It is a better idea to have a long-term study plan．Try to make a timetable for your study which lasts for a few months．
    Exercise is a great way to reduce pressure．Doing some form of exercise every day will also improve your concentration．Eat healthy food too．
    When you arrive in the examination room，find your seat and sit down．Breathe slowly and deeply．Check the time on the clock during the test，but not too often．Above all，take no notice of everyone else and give the test papers your undivided attention．
64．Which of the following statements is true according to the passage？A

17．Everyone becomes a little more forgetful as they get older，but men's minds decline（衰退） more than women's，according to the results of a worldwide survey．
    Certain differences seem to be inherent in male and female brains：men are better at dealing with mental images （useful in mathematical reasoning and spatial （三维空间） skills），while women tend to be better at recalling information from their memories （helpful with language skills and remembering the locations of objects）．
  Many studies have looked for a connection between sex and the amount of mental decline people experience as they age，but the results have been mixed．
    Some studies found more age-related decline in men than in women，while others saw the opposite or even no relationship at all between sex and mental decline．Those results could be improper because the studies involved older people，and women live longer than men．The men tested are the survivors，"so they're the ones that may not have shown such cognitive （认知的） decline，"said study team leader Elizabeth of the University of Warwick in England．
    People surveyed completed four tasks that tested sex-related cognitive skills：matching an object to its rotated （旋转的） form，matching lines shown from the same angle，typing as many words in a particular collection as possible in the given time，e．g．"objects usually colored gray"，and recalling the location of objects in a line drawing．The first two were tasks which men are usually good at； the latter are almost controlled by women．
    Within each age group studied，men and women performed better in their separate task on average．Generally speaking，women showed obviously less decline than men though performance declined with age for both sexes．
71．The underlined word"inherent"in the second paragraph meansC．
A．difficult            B．native               C．natural          D．absolute
72．Which of the following tasks are men better at？A
A．Matching lines shown from the same angle．
B．Typing as many words in a particular category as possible•
C．Recalling the location of objects in a line drawing．
D．Recalling information from their brain's files．
73．Which of the following statements can be inferred from the passage？D
A．Men are good at typing words in a particular category in the given time．
B．Women are good at dealing with mathematic problems．
C．Men do better than women when it comes to learning English．
D．Women stand out at remembering people's names．
74．What important factor affects the correctness of the research results？C
A．People tested come from all over the world．B．Men live longer than women．
C．the old men tested may not have shown such cognitive （认知的） decline．
D．The researchers got their results mixed．
75．The author aims to tell us thatB．
A．the survey on human's mind decline was done recently
B．men's minds decline more with age
C．everyone becomes a little more forgetful as they get older
D．women's minds perform better than men's．

14．

We all have our wish lists，whether it is for the holiday season，a birthday or a get-together．The fact is that we are all human and we all desire nice things and fun things．One thing that should not be missed is putting Cuponk on your wish list so that you can have years of fun and entertainment．
For adults，they can start playing Cuponk with their kids，spending quality time together，which is good for close family ties．Adults can also enjoy Cuponk with their own friends，turning a dinner party into something memorable （难忘的）．The game is made for everyone，regardless of age or gender （性别）．
It comes with a special cup with a backboard funnel （漏斗），special balls and trick cards．There are different styles of cups to choose from，just to make it even more personal an experience．The players must pick a trick card when it is their turn．The card will tell them what to do and how many times they're allowed to try that particular trick．The tricks always involve getting the ball into the cup，which will light up and make some crazy sounds of victory afterwards．
The rules allow for everything in the home to be allowable．That means that you can bounce （反弹） the ball off the wall into the cup as creatively as possible，or you can also use tables，chairs，stairs，the ceiling and whatever else you have．What makes it even more special than most others is the fact that all ages can play together．So，a family with different age groups can enjoy a few games together，without any real concern for damages，as the balls are quite light．It's kind of like beer pong rules，but without the beer．
In a time with economic instability （不稳定），where consumers have chosen to stay at home to save a few dollars，it is a great way to do that without being bored．Playing games with friends or family members is a good way to laugh and pass the time pleasantly，rather than just sitting in front of a television or a computer wasting valuable time．No one will remember watching television，but everyone will remember those memorable moments playing fun games and spending good quality time with the people they love．

68．Cuponk can be put on the wish list becauseD．
A．it is for the holiday season
B．it can help us pass time
C．it is better than a dinner party
D．it brings us pleasure
69．The underlined"it"in the third paragraph refers toB．

70．According to the text，the following can be used in the game ExceptD．

11．Can people change their skin colour without suffering like pop king Michael Jackson？Perhaps yes．Scientists have found the gene that determines skin colour．
The gene comes in two versions，one of which is found in 99per cent of Europeans．The other is found in 93to 100per cent of Africans，researchers at Pennsylvania State University report in the latest issue of Science．
Scientists have changed the colour of a dark-striped zebrafish to uniform gold by inserting a version of the pigment （色素） gene into a young fish．As with humans，zebrafish skin colour is determined by pigment cells，which contain melanosomes （黑色素）．The number，size and darkness of melanosomes per pigment cell determines skin colour．
It appears that，like the golden zebrafish，light-skinned Europeans also have a mutation（变异） in the gene for melanosome production．This results in less pigmented skin．
However，Keith Cheng，leader of the research team，points out that the mutation is different in human and zebrafish genes．
Humans acquired dark skin in Africa about 1.5million years ago to protect bodies from ultra-violet rays of the sun （太阳光紫外线），which can cause skin cancer．
But when modern humans leave Africa to live in northern latitudes，they need more sunlight on their skin to produce vitamin D．So the related gene changes，according to Cheng．
Asians have the same version of the gene as Africans，so they probably acquired their light skin through the action of some other gene that affects skin colour，said Cheng．
The new discovery could lead to medical treatments for skin cancer．It also could lead to research into ways to change skin colour without damaging it like chemical treatment did on Michael Jackson．

71．The passage mainly tells us thatD．
A．people can not change their skin colour without any pain
B．the new discovery could lead to search into ways to change skin colour safely
C．pop king Michael Jackson often changed his skin colour as he liked
D．scientists have found out that people's skin colour is determined by the gene
72．It can be inferred from the passage thatA．
A．nowadays people who want to change their skin colour have to suffer a lot from the damage caused by the chemical treatment
B．Europeans and Africans have the same gene
C．the new discovery could help to find medical treatments for skin cancer
D．there are two kinds of genes
73．Scientists have done an experiment on a dark-striped zebrafish in order toB．
A．find the different genes of humans'
B．prove the humans'skin colour is determined by the pigment gene
C．find out the reason why the Africans'skin colour is dark
D．find out the ways of changing people's skin colour
74．The reason why Europeans are light-skinned is probably thatB．
A．they are born light-skinned people
B．light-skinned Europeans have mutation in the gene for melanosome production
C．they have fewer activities outside
D．they pay much attention to protecting their skin
75．The writer's attitude towards the discovery isC．
A．neutral B．negative
C．positive D．indifferent．

12．As summer comes near，many children are really happy to forget about school for a few months．However，they might be taking that goal too seriously．Studies have found that children often forget between one and three months'worth of school learning during the summer months．Spelling and math abilities drop off the most，while reading is not really influenced by the time off．The main reason for this is because most children sometimes read outside of the classroom，whether newspapers，magazines，books，or video game guides．However，their math and spelling skills only get exercised in the school setting．
The first purpose of summer holidays was to let farm children have time off to help work in the fields during the growing season，but this reason is no longer a good one since fewer kids actually work on farms today．Some cities in the United States，such as Los Angeles，have moved to a year-round school timetable，which may help reduce the loss of school skills that happens during the long summer holiday．To improve skills and to keep a good level of preparation，headmasters suggest trips to museums，summer camps，holidays with educational value，and visits to libraries to keep kids interested throughout the summer．
There are other educational systems that provide holidays while still keeping students'skills up to date．For example，in Japan，students attend class for seven weeks in a row，followed by two weeks of holiday．This continues the whole year．In Italy，students attend class six days per week，but finish at 1：30 pm each day，so that school does not run their life the way that it does in America，where students attend high school from 7：45 am until 3：00 pm each weekday．In areas where there are not enough classrooms-in Afghanistan or Somalia，for example-older students attend classes in the morning while the younger kids go to school in the afternoon．
Headmasters fear that the three-month summer holiday stops the flow of learning．Just as students become used to new math problems or new ideas in reading，writing，or thinking skills，they"shut down"during the summer holiday．When they go back to school after the long summer holiday，they take up to two months to return to their previous （先前的） level of skill．So the debate continues：whether to continue holidays or to make changes based on the Los Angeles or the Japanese models．
74．Which skills suffer the most over the summer holidays？B
A．Math and reading．
B．Math and spelling．
C．Reading and writing．
D．Reading and thinking．
75．What can we learn about the first purpose of summer holidays？C
A．It is still widely acceptable now．
B．It was popular in some cities．
C．It is not a good reason for city kids．
D．It was more for teachers than for students．
76．The underlined phrase"shut down"in the last paragraph probably meansA．
A．stop learning
B．get sick
C．go on reading
D．focus on studies
77．What can we infer from the passage？C
A．Parents always read to their kids to keep reading skills．
B．Summer holidays lead to the loss of all the school skills．
C．Students love holidays and get their mind off learning in holidays．
D．In Italy students attend classes in the late afternoon six days a week．
