2.A.Cosmetics were used in different countries a long time ago.
B.The most widely used cosmetic is probably lipstick
C.Cosmetics were made most use of in Indian.
D.At one time,some cosmetics were not safe.
E.Some people even have cosmetic surgery.
F.The Romans also used cosmetics.

Millions of women use cosmetics,often called‘make-up'.The cosmetics industry is one of the biggest in the world.Most large stores sell cosmetics,and there are always shops at airports selling them cheaply.
The word‘cosmetics'refers to anything that people put on their faces to make them look better.Lipstick,face powder and cream,and eye make-up are the most popular.Although more women than men use cosmetics,there are cosmetics for men as well as women.
(61)E In order to make their faces look different.They have the shape of their noses and eyes changed.
(62)B Many women who do not wear any other make-up will often put on a little lipstick.Lipstick is made by mixing together different oils and colors.This mixture is then allowed to get hard and is cut into the shape of a small pencil.When a woman presses the lipstick to her lips,the end of it becomes soft,and some of it sticks to her lips,giving them extra color.
(63)A Cosmetics were probably first used in India,but it was the Egyptians,six thousand years ago,who made the most use of them.Rich Egyptian women painted their eyes green and black.They used a red color to paint pretty designs on their fingernails,the palms of their hands and the soles of their feet.Pictures of Cleopatra always show her wearing a lot of make-up.
(64)F They liked to make their skin very white and to paint their eyes.They also used a kind of lipstick.
In England at one time,very rich women had baths in milk to make their skin beautiful.They also used a lot of sweet-smelling powder to stop people smelling their bodies,which were often very dirty because they did not wash very often or change their clothes.
(65)D They were bad for the skin,and some of the lipsticks and powders that people used were even poisonous.Nowadays,people in the cosmetics industry take great care to make sure that everything they use is completely safe.

1.For better eyesight,doctors advise limiting the hours of screen time and encourage having enough eye resting time.However,another study shows that sitting in front of compute or TV screens for long hours is not the only reason for myopia (近視).An Australian research team studied young children in Sydney and Singapore to find the reasons for myopia.The research team found that there were less children who had myopia in Sydney than those in Singapore,even though they spent more time in front of computer and TV screens.The major finding is that children in Sydney spend longer hours on outdoor sports than those in Singapore.
Indoor and outdoor sports both make the eyes pay attention to more distant objects,which stops the eyes from changing original shape.But outdoor sports may be better than indoor sports for myopia.Because natural light is good for eye growth and vitamin D from the sunlight might be useful to it.Many doctors suggest that every child get its first eye test when he/she is about two and half years old,and even if his/her sight seems good enough.It is necessary for myopic (近視的)children to wear glasses to stop headaches,trouble reading and so on.It is also important that schools invite doctors to test their students eyes.
If that is not possible,school teachers should at least encourage parents and children to have regular eye examination and wear glasses.And parents should remember not only to limit the total screen time for their children,but also to encourage them to spend time outdoors.

28.Why are there fewer children with myopia in Sydney than those in Singapore?D
A.Because the children in Sydney watch TV less.
B.Because the children in Sydney have more eye resting time.
C.Because the children in Sydney use computer less.
D.Because the children in Sydney do more outdoor sports.
29.What is good for eye growth according to the passage?C
A.Natural light.
B.Vitamin D.
C.Natural light and Vitamin D.
D.The sun.
30.Which of the following is TRUE?B
A.Children should have eye tests as soon as they reach school age.
B.Looking more at distant objects can help the eyes keep their original shape.
C.Doing outdoor sports with no glasses is good for myopic children.
D.Children should limit their time in the sun to protect their eyes
31.The passage mainly tells usC.
A.the children in Sydney spend more time in front of screens
B.the children in Singapore like outdoor sports
C.doing outdoor sports and limiting the hours of screen time are good for eyes
D.it's important to test students'eyes.

20.Imagine entering a very large building and you have no idea how to get to the office you are looking for.But then,as you're standing there,a nearly silent balloon floats(飄) over to you and speaks to you.It asks you where you want to go.You tell it,and then it simply says"follow me"like a child's game,and begins to float off in the direction of your destination.It keeps going,as you follow,leading you to where you want to go.
The guide works itself,without any help from any human being.It says hello to people as they arrive in the building,speaks to them,processes their requests and then guides them to the destination.
The balloon has two tiny fans to help keep it floating and to provide just a touch of lift.Onboard is a wireless (無(wú)線的) receiver for receiving directions from a computer that directs the fans and sensors (傳感器) that let it know where objects are around it.
The idea of such a simple robot is one that has been on the minds of scientists for years,and has been mentioned in novels many times.Today the iPhone does something similar but has to be connected to the Internet which is sometimes difficult.This is why this little balloon might be the wave of the future-because it is so much easier to follow!

29.The balloon is used toA.
A.lead the way        B.bring people joy
C.catch the thief     D.welcome the visitors
30.The balloon gets to know its position with the help ofA.
A.sensors        
B.two tiny fans
C.a(chǎn) wireless receiver    
D.human beings
31.We can learn from the last paragraph thatD.
A.the idea of the balloon is new
B.the balloon is difficult to make
C.the balloon will replace the iPhone soon
D.the technology may become popular in the future
32.The text is most probably from aA.

15.The more time scientists spend designing computers,the more they wonder at human brain.Tasks that puzzle the most advanced supercomputer-recognizing a face,reading a handwritten note-are just child's play for the 3-pound organ(器官).Most important,unlike any ordinary computer,the brain can learn from its mistakes.Researchers have tried for years to program computers to imitate the brain's abilities,but without success.
Now a growing number of designers believe they have the answer:if a computer is to work more like a person and less like an over-grown calculator,it must be built more like a brain,which distributes information across a vast interconnected web of nerve cells or neurons.
Ordinary computers work by following a chainlike sequence of detailed instructions.Although very fast,their processors can perform only one task at a time.This approach works best in solving problems that can be broken down into simpler logical pieces.The processors in a neural-network computer,by contrast,form a network much like the nerve cells in the brain.Since these artificial neurons are interconnected,they can share information and perform tasks at the same time.This two-dimensional approach works best at recognizing patterns.
Instead of programming a neural-network computer to make decisions,its maker trains it to recognize patterns in any solution to a problem by repeatedly feeding examples to the machine.Neural networks come in all shapes and sizes.Until now most existed as software simulatio ns (模擬品) because redesigning computer chips took a lot of time and money.By experimenting with different approaches through software rather than hardware,scientists have been able to avoid costly (昂貴的) mistakes.
56.It can be inferred from the first two paragraphs that the most advanced supercomputerD.
A.can recognize a face and read a handwritten note
B.can learn from its mistakes
C.weighs only 3 pounds
D.can't distribute information across an interconnected web of nerve cells
57.An ordinary computer can usually do the following except thatD.
A.it must be programmed before it works
B.it can only solve one problem at a time
C.it is good at solving problems that can be broken down into simpler logical pieces
D.it is trained to make decisions
58.The main feature of a neural-network computer is thatA.
A.its processors act as an interconnected web of neurons
B.it is programmed to make decisions
C.its networks are of all shapes and sizes
D.its neurons are artificial
59.What does"this two-dimensional approach"in the third paragraph refer to?C
A.the conventional computer and the neural computer.
B.making decisions and recognizing patterns.
C.sharing information and performing tasks.
D.the computer and the human brain.
60.Scientists use software rather than hardware in their experiments becauseB.

14.Climate change will bring greater extremes in weather,the Government's chief scientific adviser has warned as he called for action to deal with global warming.Professor Sir John Beddington says the effects of climate change on the weather are already being felt in the UK.
"In a sense we have moved from the idea of global warming to the idea of climate change,and that is rather important.Temperatures are increasing and there are more changes in our weather,"he said.
Even if effective action is taken now on global warming,he says there will be great climate change over the next 20 to 25 years as a result of past global problems.
"We have serious problems in the world---in 12 years there will be another billion people on the planet and we have big issues of food security,water security and energy security,and many people will start to be living in cities,"he said."These are serious problem; climate change is just going to make it worse."
He said there were some"uncertainties"in the analysis of climate and climate change."But those uncertainties are completely unimportant in comparison(比較)with a great deal of evidence that shows it is happening in the sort of ways climate models would expect,"he said."For example,the Arctic is heating up faster than other parts of the world---this is exactly what the climate scientists are predicting."
Sir John's views were made as Britain e xperienced freezing cold weather and snow,with thousands of homes across the UK without power.England and Wales experienced 10 separate flooding events between April and December last year after widespread drought gave way to the wettest summer in a century,with unusually high rainfall totals and river levels around the country.
61.Which of the following is NOT one of the things that Sir John says?D
A.We need more action to deal with global warming.
B.Climate change will make some big problems worse.
C.Climate change will bring greater extremes in weather.
D.England will experience more extremes in weather than Wales.
62.How long will it be before our planet has another billion people?C
A.25 years.B.20 years.C.12 years.D.10 years.
63.What is Sir John's attitude towards the Climate scientists'prediction?B
A.Puzzled.B.Trusting.C.Uncertain.D.Doubtful.
64.In recent years,which of the following has the UK NOT experienced?D
A.Widespread drought.
B.Many flooding events.
C.Freezing cold weather.
D.Several big earthquakes.
65.What is the main purpose of this report?A
A.To call for effective action on climate change.
B.To introduce Professor Sir John and his opinions.
C.To prove that the UK has experienced a series of disasters.
D.To show how correct the climate scientists'predictions are.

13.If you thought it was cold where you are at the moment,then a visit to the Russian village of Oymyakon might change your mind.
With the average temperature for January of 2013standing at-50℃,it's no wonder that the village is the coldest place in the world with people always living.The coldest ever temperature recorded in Oymyakon was-71.2℃.And despite its terrible winters,in June,July and August temperatures over 30℃are not uncommon.
In Oymyakon most homes still burn coal and wood for heat.Nothing grows there so people eat reindeer(馴鹿) meat and horse meat.The local people work as reindeer-keepers,hunters and ice-fishermen.Here there is a single shop and there is only a school,which only shuts if temperatures fall below-52℃.
There are few modern conveniences in the village.Many buildings still have outdoor toilets.When coal deliveries are irregular,the power station starts burning wood.If the power stops,the town shuts down in about five hours,and the pipes freeze and break.
What troubles people living in Oymyakon in their everyday life includes pen ink freezing,and glasses freezing to people's faces.Locals are said to leave their cars running all day for fear of not being able to start them again.Another problem caused by the cold temperatures is burying dead bodies.The earth must first have thawed(解凍) enough in order to dig it,so a fire is lit for several hours.Hot coals are then pushed to the side and a several-inch-deep hole is dug.The process is repeated for several days until the hole is deep enough to bury the coffin(棺材).
Travel companies offer tourists the chance to visit the village and experience life in the freezing conditions.
