15．Not very long ago，the question would have seemed absurd．Now it is on the lips of respected scientists； MPs（议员） are beginning to talk of"a war on sugar"，and even England's chief medical officer has said sugar may have to be，like the old enemy tobacco，taxed in order to protect the nation's health．
There came a time in the evolution of public attitudes to smoking，when the doctors had been shouting for long enough that the public was broadly aware of the risks and the only question left，for Government was：what should we do about it？
Some believe we are now at the same point in our attitudes to sugar．Others-largely but not only representatives of the food and drink industry-say the entire debate has been skewed，（歪曲） by those who spread stories deliberately to make people nervous．
More or less everyone agrees that eating too much sugar is bad for you．There is also no doubt obesity is a growing problem which is putting a significant，avoidable burden on the NHS by increasing the rates of diabetes，heart disease and other long-term conditions．
But to what extent is sugar-rather than saturated fats，or salt，carbohydrates or proteins，or any of the other devils of modem diets-the cause of obesity and how much should we worry about it？
Yesterday，hopes of achieving anything resembling clarity（清楚） from the World Health Organization （WHO） were confused once again，which，widely expected to reduce the recommended sugar intake by a half in new draft guidance，instead said it would continue to recommend that sugar make up no more than 10per cent of the energy we consume，while adding that cutting this to five per cent would have"additional benefits"．The decision will now go out to public consultation．
Simon Capewell，professor of the University of Liverpool，said that he suspected"dirty work"on the part of food and drinks companies might lie behind the WHO's less than resounding message．
"The food industry say Government has no business interfering（介入） in families，we must protect personal choice，"Professor Capewell said．"We say there is no personal choice．At the moment，a mother can walk into a supermarket with a choice of four tomato soups-with three，or four，or five teaspoons of sugar in them．She has a choice of thousands of ready meals-with five，or six，or even nine teaspoons of sugar in．"

59．By referring to smoking the author indicates thatB．
A．sugar has just turned out to be as harmful as smoking
B．it is not easy for authorities to restrict or ban something
C．it is easy for people to see bad effects of something
D．people must see the disadvantages of sugar immediately
60．WHO has changed its idea mainly becauseC．
A．it thinks the danger of sugar to health is overemphasized
B．it finds it safe to take in as much sugar as people do now
C．it believes certain amount of intake of sugar does us good
D．it has been put under pressure by food and drinks companies
61．When reporting the argument about sugar，the author seems toB．
A．remain objective B．stand by those against it
C．believe it harmless D．hold the view of"wait-and-see"
62．Which of the following can be the proper title for the passage？A
A．Is sugar the new evil？B．How much sugar do you take daily？
C．Is sugar to be taxed？D．How much do you know about sugar？

1．The hit movie Finding Nemo follows a clownfish from the Great Barrier Reef． In real life，clownfish are among the thousands of colorful sea creatures that call the Great Barrier Reef home．Stretching l，250 miles along Australia's northeastern． coast，the Great Barrier Reef is the longest coral reef in the world．
    A coral reef is a living underwater structure． But these days，the Great Barrier Reef has found itself in trouble．Overfishing，pollution，and high temperatures are harming its health． That's why the government in Australia is trying to help rescue the reef．
Underwater Garden
   While coral may look like a plant，it is actually made up of tiny sea animal．Those sea animals are called coral polyps．
   As polyps die，they leave hard．shells behind． Other polyps grow on top of the shells．Over thousands of years，they form a coral reef in warm water that is not very deep．
   In many ways，the Great Barrier Reef resembles an underwater garden． Coral can be hard or soft．It forms in different colors and in strange shapes．Some coral looks like hardened brains． Other coral looks like fans and lettuces．
  The reef bursts with schools of tropical fish，dashing among gaps in the coral．The reef supplies food． and． shelter to creatures living in and around the coral． Turtles，sharks，sea horses，and crabs are among its many inhabitants．
Helping Humans
     While the reef is important to ocean life，it helps humans，too． People rely on the reef for both food and jobs． It also provides medicine used to treat disease． Each year，the Great Barrier Reef contributes about $ 975 million to the economy through tourism and fishing．
Stressed Out
    Is it surprising，then，that the Great Barrier Reef is under too much stress？Fishing nets and ships break off sections and damage the reef． Air and water pollution are also doing harm． At the same time，warmer sea temperatures have caused coral bleaching（漂白） on half of the reef． The high temperatures cause the coral to turn white，often killing it．
Reef Rescue
    In an effort to help save the reef，the government has limited fishing to two thirds of it． That plan increases the number of"green zones．"Those are areas that are off-limits to fishermen and boats． However，tourists and researchers can still visit them． Many fishermen are upset about the plan because they rely on the reef for jobs．
     The Australian government says that its plan will help keep the reef safe from some threats．"It is very important that we give   B reef proper protection for the future，"said one government official． The reef is Australia's greatest natural treasure．

B． Fish moving toward the center，or target，of the coral．
C． Structured，orderly groups of young fish without a clear path．

A． The causes of reef problems an possible solutions．

8．Chicago is considering firm measures to prevent the Asian carp，a giant fish native to the Far East，from coming into North America's Great Lakes in large numbers．Such a move could cost up to$18bn，a heavy economic burden to the city．
This species，more than a metre in length，was originally introduced to southern US states three decades ago to control weeds in sewage（污水）treatment plants．But they escaped into the Mississippi River and increased in number quickly，making their way north towards the Great Lakes and threatening the native fish species along the way．
"Dozens of them will often leap out of the water as boats approach．''Michael Beecham，a local environmental expert，described how frightening the scene was．"I've gone down the river and seen these fish jump up and hit me in the face．It is a big problem for our native species，"he said．
A meeting has been organized to find a technological solution to the carp problem，one of which involves blocking parts of Chicago's canal system．Listening at the meeting was John Goss，who was worried about the effect that having barriers in the canal system would have on industry．"It would certainly increase the cost of transportation，"he told．"It is currently very cheap and efficient to bring materials and finished goods down the Chicago ship canal．"
Another cheaper option is to eat the fish out of existence．Dirk Fucik is selling carp burger（鲤鱼汉堡包）at his fish shop not far from downtown Chicago．He thinks the carps are a great resource．"To catch it and throw it away is a waste，"he says．"Eating them helps solve the problem and also provides jobs．"But the idea has not yet caught on．So far，he is the only person in Chicago selling carp burgers．

6．Were you the first or the last child in your family？Or were you a middle or an only child？Some people think （61）itmatters where you were born in your family．But there are different ideas about what birth order means．Some people say that oldest children，（62）whoare smart and strong-willed，are very likely（63）to succeed（succeed）．The reason（64）forthis is simple．Parents have a lot of time for their first child and give him or her a lot of attention．An only child will succeed for（65）thesame reason．
