Certain forms of AI are indeed becoming ubiquitous. For example， algorithms （算法） carry out huge volumes of trading on our financial markets， self﹣driving cars are appearing on city streets， and our smartphones are translating from one language into another. These systems are sometimes faster and more perceptive than we humans are. But so far that is only true for the specific tasks for which the systems have been designed. That is something that some AI developers are now eager to change.
Some of today's AI pioneers want to move on from today's world of "weak" or "narrow" AI， to create "strong" or "full" AI， or what is often called artificial general intelligence （AGI）. In some respects， today's powerful computing machines already make our brains look weak. AGI could， its advocates say， work for us around the clock， and drawing on all available data， could suggest solutions to many problems. DM， a company focused on the development of AGI， has an ambition to "solve intelligence". "If we're successful，" their mission statement reads， "we believe this will be one of the most important and widely beneficial scientific advances ever made."
Since the early days of AI， imagination has outpaced what is possible or even probable. In 1965， an imaginative mathematician called Irving Good predicted the eventual creation of an "ultra﹣intelligent machine …that can far surpass all the intellectual （智力的） activities of any man， however clever." Good went on to suggest that "the first ultra﹣intelligent machine" could be "the last invention that man need ever make."
Fears about the appearance of bad， powerful， man﹣made intelligent machines have been reinforced （强化） by many works of fiction﹣Mary Shelley's Frankenstein and the Terminator film series， for example. But if A I does eventually prove to be our downfall， it is unlikely to be at the hands of human﹣shaped forms like these， with recognisably human motivations such as aggression （敌对行为）. Instead， I agree with Oxford University philosopher Nick Bostrom， who believes that the heaviest risks from AGI do not come from a decision to turn against mankind but rather from a dogged pursuit of set objectives at the expense of everything else.
The promise and danger of true AGI are great. But all of today's excited discussion about these possibilities presupposes the fact that we will be able to build these systems. And， having spoken to many of the world's foremost A I researchers， I believe there is good reason to doubt that we will see AGI any time soon， if ever.

I know what you're thinking: pizza? For breakfast? But the truth is that you can have last night's leftovers in the a. m. if you want to.
I know lots of women who skip breakfast, and they have a ton of different excuses for doing it. Some say they don't have time, others think they're “saving” calories, still others just don't like breakfast food.
But the bottom line is that eating in the morning is very important when you’re trying to lose weight. “Eating just about anything from 300 to 400 calories would be better than nothing at all,” says Katherine Brooking, R, D, who developed the super-easy eating plan for this year’s “SELF CHALLENGE”. And even pizza can be healthy if it's loaded with vegetables, and you stick to one small piece.
Breakfast is one meal I never miss, and the same goes for most weight loss success stories. Research shows that eating breakfast keeps you from overeating later in the day. Researchers at the University of Southern California found that breakfast skippers have a bigger chance of gaining weight than those who regularly have a morning meal.
So eat something in the morning, anything. I know plenty of friends who end up having no breakfast altogether, and have just coffee or orange juice. I say, try heating up last night’s leftovers－it may sound crazy, but if it works for you, do it! I find if I tell myself, “You can always eat it tomorrow,” I put away the leftovers instead of eating more that night. Try it... you may save yourself some prebedtime calories. And watch your body gain the fatburning effects.The underlined word "leftovers" in Paragraph 1 probably means ______.
| A．food remaining after a meal | B．things left undone |
| C．meals made of vegetables | D．pizza topped with fruit |
What can we infer from the text?
| A．Working women usually have breakfast in a hurry. |
| B．Many people have wrong ideas about breakfast. |
| C．There are some easy ways of cooking a meal. |
| D．Eating vegetables helps save energy. |
According to the last paragraph, it is important to ______.
| A．eat something for breakfast | B．be careful about what you eat |
| C．heat up food before eating it | D．eat calorie- controlled food |
The text is written mainly for those _______.
| A．who go to work early | B．who eat before sleep |
| C．who stay up late | D．who want to lose weight |
The rising costs of health care have become a problem for many countries in the world. To deal with this problem, it is recommended that a big part of the government's health budget be used for health education and disease prevention instead of treatment. Actually, many kinds of diseases are preventable in many ways and preventing a disease is usually much cheaper than treating it. For example, people could avoid catching a cold if they dressed warmly when the weather starts getting cold. But many people get sick because they fail to do so, and have to spend money seeing a doctor
Daily habits like eating more healthy food would have kept millions of families from becoming bankrupt if the patients had taken measures for early prevention. For instance, keeping a balanced diet, such as not consuming too much animal fat and insuring a steady intake of vegetables and fruits, seems to be quite important.
One very effective and costless way of prevention is regular exercise, which is necessary for a healthy mind and body. Regular exercise, such as running, walking, and playing sports is a good way to make people feel better or reduce stress
In addition, health education plays a key role in improving people's health. By giving people more information about health, countries could help people understand the importance of disease prevention and ways to achieve it. For example, knowing one's family medical history is an effective way to help keep healthy. Information about health problems among close relatives will make them aware of what they should do to prevent certain diseases through lifestyle changes, which will work before it is too late
However, stressing disease prevention does not mean medical treatment is unimportant. After all, prevention and treatment are just two different means toward the same effect. In conclusion, we could save money on health care and treat patients more successfully if our country spends more money on health prevention and educationWhat’s the best title of the passage?
| A．Prevention or Education? |
| B．Prevention or Treatment? |
| C．Health or Illness? |
| D．Exercise or Illness? |
Which of the following can replace the underlined word “bankrupt’’?
| A．Unable to be cured |
| B．Unable to pay one’s debts |
| C．Stronger than ever before |
| D．More successful than ever before |
We learn from the passage that
| A．dressing warmly can prevent diseases |
| B．a balanced diet is cheaper than regular exercise |
| C．the more health education, the better |
| D．the government’s health budget should be increased |
Which of the following shows the structure of the passage?

LONDON: What could possibly be wrong with planting trees? The advantages are obvious; they firm the soil, soak up (摄取) extra water and take carbon dioxide (二氧化碳) out of the atmosphere.
However, it now turns out that planting trees could add to global warming.
Tree roots do a great job of keeping soil firmly on the ground and out of the wind’s power. The problem is that some of those dust clouds play an important part in soaking up carbon dioxide.
Huge dust storms blow out over the oceans from dry parts of North Africa and central Asia. Tons of dust are lifted and left as a thin film over the ocean surface. The dust fuels oceanic life.
Dust from China is carried east and left in the Pacific Ocean. If a tree-planting programme there is successful and the dust supply reduced, the net result may be that less carbon dioxide gets locked away in the ocean.
Andy Ridgwell, an environmental scientist from the University of East Anglia, has spent the past few years studying dust and says his work “shows clearly the complexity of the system and the importance of not tinkering(粗劣地修补) with it without understanding the results. For this reason there is the need to focus(集中) on cutting carbon dioxide giving off rather than monkeying (瞎弄) about with the land surface.”
An American scientist, Robert Jackson, has shown that when native grassland areas are invaded(侵入) by trees, carbon is lost from the soil. “We are studying why the soil carbon disappears, but one theory is that trees do a lot more of their growing above ground compared to grasses, so less carbon goes directly into the soil from trees, ” says Jackson.
In wet areas of the world, the gain from trees absorbing carbon dioxide above ground seems to be outweighed(超过) by the loss of carbon from the soil below ground. Countries that plan to combat global warming by planting trees may have to think again. Solutions(解决办法) to environmental problems are often more complex than they first appear, and understanding the Earth’s climate is a very great challenge.People usually hold the opinion that
| A．huge dust storms can destroy carbon dioxide |
| B．huge dust storms can destroy the oceans on the earth |
| C．huge dust storms can’t do anything beneficial for man |
| D．planting trees is the only way to control huge dust storms |
Andy Ridgwell, the environmental scientist, believes that
| A．dust plays a more important part than trees |
| B．trees shouldn’t have been planted in dry places |
| C．carbon dioxide is harmful to everything on the earth |
| D．environmental problems are more complex than expected |
Robert Jackson’s experiment proves that
| A．grassland areas should be covered by forests |
| B．trees hold more carbon than grass |
| C．carbon can turn grass into dust |
| D．less carbon can make trees grow faster |
The underlined word “combat” in the last paragraph means
| A．learn about | B．fight against | C．live with | D．give up |
When Jackie Robinson walked onto Ebbets Field in Brooklyn, New York, on April 15, 1947, he changed baseball forever. As the first African American to play in the Major League in modern times, many believe he changed the country forever.
Robinson was born in 1919. He lived in a time when rules controlled what African Americans could do. He was a top athlete, playing football, basketball and baseball. But playing for a major League team was off limits to Robinson because of his race.
Branch Rickey, president and manager of the Brooklyn Dodgers, signed (和……签约) Robinson in 1947. He believed that Robinson not only had the skills, but the courage to face the challenge of becoming modern baseball’s first black player.
It wasn’t easy. Robinson sometimes faced boos (嘘声) from fans. But he became a star, anyway. In 1962, he became the first African-American player chosen to enter the Baseball Hall of Fame. In 2005, he was awarded a Congressional Gold Medal, the highest award Congress can give to an American.
By breaking baseball’s color barrier (肤色障碍), Robinson opened the door for many to follow his footsteps, not only in baseball, but in other areas of life as well. After he stopped playing the game, Robinson worked as a manager for a coffee company. He wrote a newspaper column (专栏). He also started a bank. Before Jackie Robinson, no African-American players could __________.
| A．play baseball |
| B．play in the Major League |
| C．play football and basketball |
| D．watch Major League games |
According to Branch Rickey, Jackie Robinson was __________.
| A．poor but clever | B．unlucky but confident |
| C．proud and strong | D．brave and skilled |
We can know that Jackie Robinson’s story __________.
| A．changed many Africans’ ideas |
| B．had an effect on many black people’s lives |
| C．encouraged black people to fight with whites |
| D．started a hot discussion about the color barrier |
Which of the following is NOT what he once did?
| A．a newspaper column writer | B．a banker |
| C．a university teacher | D．a manager in a company |
