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
A．Check the time during the exam at a certain time．
B．Your concentration will improve if you study and watch TV at the same time．
C．You should study in a different place every day，so you don't get bored．
D．Staying up all night and studying is tiring，but you will learn a lot using this method．
65．What does the underlined word"it"refer to？C
A．Your dictionary．
B．Your textbook．
C．Your study desk or table             
D．The equipment you need．
66．What can be inferred from the passage？B
A．You shouldn't look at everyone else during the test．
B．You will have enough energy to deal with your study and exams by eating healthy diet．
C．You'll concentrate more if there is nothing to distract you．
D．If you feel tired during study，you can walk around for a few minutes．
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．
8．You're lost in the world of dreams and sleep．You roll over，smiling as you come across a swimming pool filled with chocolate．And then，your wonderful dream becomes a nightmare when someone is screaming，"Get up!"It's just what every teenager goes through each morning!
Now，there seems to be one school that finally understands that requiring teens to show up at 9am is not just cruel but also harmful to both the kids and the school．
The Monkseaton High School in North Tyneside，Britain，recently decided to experiment to see if there is any difference in student behavior if they just pushed back the start of their day by one hour，from 9am to 10am．And the results are surprising．
Since carrying out the later start，Monkseaton has seen a 28% drop in  truancy，even hardly any lateness，and best of all，higher test scores．One of the reasons is that the teenagers are much happier to have the extra hour of sleep，but there is also a scientific reason behind why they need the extra sleep．
The school's decision to push back the time was based on the research done by Oxford Professor Russell Foster，who pointed out that teenagers and adults have different sleep cycles，explaining why teenagers go to bed late and wake up late．
While adults are wide awake and ready at 8am，teenagers are not fully awake until 10am，sometimes even noon．Teachers may argue that their students perform better in the morning，but in fact，it is because they are in the zone while their students are still sleepy，making the students easier to control．Memory tests prove that the more difficult classes should be in the afternoon when teenagers are most wide awake．
The Monkseaton school officials are encouraged by the results and plan on voting to make it a permanent change．

67．What's the best title of this passage？B
A．Get up early，teenagers!
B．Finally，a school understands teenagers．
C．Why do teenagers stay up late？
D．Difference between teens and adults．
68．What's the meaning of the underlined word"truancy"？C
A．grades         B．subjects
C．absence        D．classes
69．What can we learn from the passage？D
A．Teenagers and adults have the same sleep cycle．
B．Teenagers are fully awake at 10am．
C．Teenagers are much happier to sleep than study．
D．Teenagers need the extra sleep also for a scientific reason．
70．Which of the following statements is NOT true according to the passage？D
A．The Monkseaton school is satisfied with the result of experiments．
B．It is cruel for the teenagers to show up at 9am．
C．The Monkseaton school plans to change the school time forever．
D．Teenagers perform better in the morning than in the afternoon．
15．Pulling luggage through the airport can be a pain，as any frequent traveler will tell you．A new suitcase called only"Hop"is looking to change all of that，though，using signals from your cell phone to go hands-free．
According to Hop's official website，the suitcase uses three sensors （感应器） to identify the Bluetooth signal from your phone and pick you out of a crowd．Once it's done that，a microprocessor not only figures out Hop's position as it relates to your phone，but controls the two caterpillar tracks （履带） in the bottom of the unit to get it moving．Hop follows behind the user at a constant distance，so you don't have to worry about it"stepping"on your heels，so to speak．If it loses the signal it's following，your phone will vibrate，letting you know that your poor suitcase is lost and alone in a sea of strange people．
We can see Hop in action in the video below，and we have to say that it looks like a great little device．There's just one problem：it looks as if you'll have to walk at a relatively slow pace to keep the suitcase from losing the signal．Since a walk through an airport is rarely a leisurely experience，that could potentially cause troubles．Also，don't expect TSA agents to just smile and wave as you walk through security with a remote-controlled suitcase tailing you．
Still，the idea behind Hop is really cool，and we're willing to believe that there are some frequent flyers who would like to put down some money for it right this instant．However，this is just a model at the moment，so don't expect it to be available for sale anytime soon （if it ever is，for that matter）．Would you purchase one of these if Hop ever became available commercially？
66．What is"to go hands-free"？A
A．The new suitcase
B．Your cell phone．
C．Signals from your cell phone
D．Frequent travelers．
67．Which paragraph tells about how Hop works？B
A．Paragraph One
B．Paragraph Two
C．Paragraph Three
D．Paragraph Four．
68．The article is probably taken fromB．
A．Hop's official website                   
B．a website of worldwide news
C．a Western newspaper                   
D．a Chinese newspaper
69．According to the article，Hop may run into trouble becauseC．
A．your cell phone fails to tell you Hop is lost 
B．its caterpillar tracks aren't powerful enough
C．you usually walk too fast for Hop to follow   
D．TSA agents won't be patient enough
70．What does the writer think of the invention？D
A．Hop will be in production soon
B．Hop is sure to be popular someday．
C．It's silly to have thought of that
D．Hop might never go on sale．
5．High in the sky，a group of birds fly past．The 5-foot-tall creatures are whooping cranes，the tallest birds in North America noted for its loud call．The wild animals appear to be following much larger birds．But those aren't birds at all．They are three-wheeled aircraft called trikes，and the pilots flying them are wearing white helmets and white gowns．That plan might sound like a stupid idea，but it's not．The pilots are from an organization called Operation Migration．They are helping the whooping cranes learn to migrate，or move from one area to another when the seasons change．The cranes are endangered．In 1941，the species had dwindled（减少）to roughly 20 birds because of hunting and habitat loss．US wildlife officials counted 149 whooping cranes in November 1995，the most since the American government began taking censuses（统计）in the 1930s．Today，about 380 remain．
In the fall，whooping cranes are supposed to migrate south．However，many of them don't know how．"With so few birds left，young whooping cranes typically don't have parents around to teach them，"explains pilot Joe Duff．
That's where the trikes come in．Each October，pilots dress up as whooping cranes and take to the skies in Wisconsin．The young birds follow them because they think the trikes are big whooping cranes．
It takes about three months to reach south-with plenty of rest stops on the way．The pilots lead the cranes to refuges，or protected areas，in Florida．
This spring，the birds will migrate north by themselves-no trikes needed!"It's nice because you know the birds are going to make it，"Duff told WR News．

C．the cranes get lost frequently
D．the cranes fly to Florida nonstop
44．According to the passage，which of the following is TRUE？D．

C．Whooping cranes are becoming endangered．
D．Whooping cranes are a clever species．
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．
9．It was ridiculous to be offeredsympathy（同情） by a robot．
