As a teenager of the digital era, it is really hard to say no to fantastic electronic gadgets(电子产品). Many of us can’t get through a day without using our mobile phones or checking our e-mails. No matter if we’re “@home”, “@school” or“@play”, living without technological toys seems more and more unthinkable.
However, although gadgets bring convenience, many of us can start to feel stressed out by them. And, a lot of electronics are fairly expensive. Fashionable gadgets come and go in the digital age in the blink of any eye. So, think twice before you pulling out your wallet.
Here are some of the most popular gadgets and their pros and cons:
Pros: Laptops have made our lives much easier. You can take your books, movies, music and homework everywhere.
Cons: They cost at least 4,000 yuan! If you only want to share photos or games with your friend, then a flash memory stick is a great cheap alternative.
Pros: As well as carrying your favourite music, a video MP3 player can play up to 150 hours of movies and TV programmes.
Cons: The price—sometimes more than 2,000 yuan—is the first concern. Secondly, though music is really important to young people, ask yourself if video is really necessary. A regular MP3 player is a lot cheaper. And remember, don’t let the loud volume damage your hearing.
Pros: New mobile phones combine traditional functions with a digital camera, MP3 player and even a radio. Some can also send and receive e-mails.
Cons: Always trying to keep up with the latest model can be a waste of money. There are always new, improved phones coming out. Don’t be a fool. Do you really need all these functions? Think twice before you buy.

B
As a result of pollution, Lake Erie, on the borders of the USA and Canada, is now without any living things.
Pollution in water is not simply a matter of “poisons” killing large numbers of fish overnight, Very often the effects of pollution are not noticed for many months or years because the first organisms（生物体）to be affected are either plants or plankton(浮游生物). But these organisms are the food of fish and birds and other creatures. When this food disappears, the fish and birds die too. In this way a whole food chain can be wiped out, and it’s not until dead fish and water birds are seen at the river’s edge or on the seashore that people realize what is happening.
　　Where do the substances which pollute the water come from? There are two main sources of sewage（下水道污物）and industrial waste. As more detergent（洗涤剂）is used in the home, so more of it is finally put into our rivers, lakes and seas. Detergents harm water birds, dissolving the natural substances which keep their feathers water-proof (防水). Sewage itself, if not properly treated, makes the water dirty and prevents all forms of life in rivers and the sea from receiving the oxygen they need. Industrial waste is even more harmful as there are many highly poisonous things in it, such as copper and lead.
　　So, if we want to stop this pollution, the answer is simple: sewage and industrial waste must be made clear before flowing into the water. It may already be too late to save some rivers and lakes, but others can still be saved if the correct action is taken at once.
70. Pollution of water is noticed________.
　　A. when the first organisms are affected　     
B. when a good many fish and birds die

72. Which of the following is harmful according to the passage?
　　A. Organisms              　B. Plants and plankton in the water

　　C. make the waste material harmless before flowing into the water
　　D. make special room in the sea for our rubbish

One of the main challenges facing many coutries is how to maintain their identity in the face of globalization and the growing multi-language trend. “One of the main reasons for economic failure in many African countries is the fact that,with a few important exceptions,mother-tongue
education is not practiced in any of the independent African states." said Neville Alexander.Dutctor of the Project for the Study of Aitemative Education in South Africa at the  University of Cape Town.
In response to the spread of English and  the increased  multi-language trends arising from Immigration . many countries have inuoduced language laws in the laws in the last decade .In some ,the use  of languages other than the national language is banned in public spaccs such as advertsing  posters.  One of the first such legal proviaions was the  1994  " Toubon law'  in France. but the idea hs been copied in many counuics since then. Such efrorts to govern language use are often
dismisscd as futile by language experts . who are well aware of the difficulty of controlling fashions in specch and know  from research  that language switching among bilinguals is a natural process.
It is especiaLly difficult for native speakers of English to understand the desire to maintain the 'purity" of a language by law.  Since the time of Shakespeare . English has continually absorbed
foreign words into its own language. EngLish is one of the most mixed and rapidly changing languages in the world. But the  has not been a barrier to acquiring prestige and power. Another reason for the failure of many native English speakers to understand the role of state regulation is that it bas never been the Aryllo-Saxon way of doing things. English has never had a state-controlled
autharity for the language,  similar, for example . to the Academie Francaise in France.
The need to prorect national languages is for most western Europeansa recent phenomenon- especially the need to ensure that English does not unnecessarily take over too many fields.
Public communication, educauon and new modcs of communication promoted by technology,may be key fields to defend.

A. mother-tongue education is not practiced in all African countries
B. lack of mother-tongue education can lead to economic failure

D. globalization has resulted in the econonuc failure of Africa

As a kid, I can remember going to the supermarket and grabbing eggs off the shelf. I would run them home to my mother because they were usually going into a delicious cake. Times have changed. Cage-free? Organic? Brown? White? Omega-3s(一种脂肪酸)?Help! Here are some tips to help you figure out which eggs you should be eating.
Brown or white? In fact, color is simply a sign of the breed of hen. Find the freshest egg with the most flavor and let color be a secondary concern.
Extra Omega-3s? Omega-3 eggs come from a hen whose diet has added flaxseed (亚麻籽)，which produces an egg containing an average of 225 mg of Omega-3 fatty acids and vitamin E. The countless health benefits for humans make these eggs an attractive purchase. My opinion? Eat a piece of fresh fish and get a pure pill of Omega-3s. Let eggs be eggs.
Does your egg need exercise? Free-range eggs are from hens raised without the limit of a cage, though they may or may not have spent much time outdoors. Organic eggs are from hens whose food must meet organic standards. These hens must be raised humanly, and they must be given time to the outdoors. Hey, happier hens do lay tastier eggs.
Does local make a difference? Nothing is better than local eggs. They may have a feather or two stuck to them or be a little imperfect in shape and may or may not be certified organic; however, they have one quality. I know exactly where my food came from and how it came into being! In some cases I can even ask the farmer when the eggs were laid and what they were fed.
55.What’s the best title for this passage?
A．Which Eggs Should You Be Eating?       B．Eggs Are Changing as Times Are Changing

A．They are a good choice for people to buy.   
B．They contain fewer Omega-3s than fresh fish.
C．They have the highest content of pure Omega-3s.
D．They are not the best source of Omega-3s.
57. The underlined word “free-range” probably means “________ ”
A．wild        B．cage-free         C．organic        D．Omega-3-free

American researchers say drinking tea may help strengthen the body’s defense system against infection（感染）．Doctors at Brigham and Women’s Hospital in Boston，Massachusetts，did the study．The team studied a chemical found in black，green，oolong and pekoe tea This chemical is an amino acid（氨基酸）called L-theanine．The scientists say it may increase the strength of Gamma delta T cells，which are part of the body’s defenses．

First，the researchers mixed some of these cells with antigens（抗原）found in the amino acid Antigens help the body react to infection．Then the scientists added some bacteria（细菌）．

Within twenty-four hours，the cells produced a lot of interferon，a substance that fights infection Cells not mixed with the antigens did not produce interferon．

In the second part of the study，eleven people drank five to six cups of black tea every day．Ten other people drank the same amount of instant coffee．That is dried coffee mixed with hot water．

Two weeks later，and again two weeks after that，the researchers tested the blood of all twenty-one people．They also looked at what happened when they added bacteria to the blood cells．They found that the tea drinkers produced five times more interferon after they started drinking tea The coffee drinkers did not produce interferon．

Doctor Jack Bukowski led the study He says the antigens added to the Gamma delta T cells were responsible for the increased reaction to the bacteria．He says the study also showed that the cells were able to remember the bacteria and fight them again the next time．

Earlier research already has found that tea can help prevent heart disease and cancer Doctor Bukowski says the new study must be repeated with more people．If the findings prove to be true，he says，then tea drinking might also help protect against bacterial infections．He says the amino acid L-theanine could be removed from tea and used as a drug to strengthen the body’s defenses．

73．We may know from the text that     can be found in different kinds of tea．

A．Gamma delta T cells                               B．L-theanine

C．interferon                                       D．bacteria

74．Tea may help strengthen the body’s defense system because it helps    ．

A．the body to produce more interferon

B．the body to produce more Gamma delta T cells

C．to add some bacteria to the blood cells

D．to mix antigens with some of the cells in the body

75．According to Dr Bukowski，    ．

A．the findings of the study have already proved to be true

B．he bas taken some amino acid L-theanine from tea and made a drug with it

C．further study is needed to prove the findings true

D．he is not sure whether tea can help prevent heart disease and cancer
