Researchers believe that the insect(昆虫) is better at managing congestion (拥挤) than humans. Ants are the most many type of animal on earth with brains that contain about 250,000 cells ---- the largest among insects.
Now an intelligence expert Dr. Dirk Helbing says understanding more about ants could help solve one of the headaches of modern life -- road congestion.
His team set up an "ant motorway" with two routes of different widths from the nest to some sugar syrup (糖浆). Soon the narrower(更窄的) route soon became crowded(拥挤的). But when an ant returning along the crowded route to the nest met with another ant just starting out, the returning ant pushed the newcomer onto the other path. However, if the returning ant had enjoyed a trouble-free journey, it did not send the newcomer in a different direction.
The result was that just before one route became clogged , the ants had turned to another route and traffic jams never formed.
The researchers also created a computer model of more complex ant networks with routes of different lengths. The team found that even though ants being sent in another direction sometimes took a longer route, they still got to the food quickly and efficiently.
Dr. Helbing, of the Dresden University of Technology in Germany, said that while you cannot allow cars to meet with traffic coming in the opposite(相反的)direction as a form of traffic control, you could do the next best thing and allow them to communicate.
His plan is to force cars traveling in one direction to tell oncoming traffic what the conditions they are about to meet with-- so they can avoid that situation if necessary.
1.The first paragraph suggests that _______.
A.ants have a special way to manage congestion |
B.ants are clever and good at dealing with the traffic jams because of developed brain |
C.insects are similar to animals in dealing with the traffic jams because of developed brain |
D.insects have more advantages than humans |
2. The underlined word "clogged" can be replaced by _______ in the following four words.
A.cleaned | B.narrowed | C.crowded | D.shortened |
3.If an ant returns along crowded route to the nest, how does the ant solve the traffic problem?
A.The ant will change the direction of its own. |
B.The ant stopped the newcomer from moving ahead and forced the newcomer to wait there patiently. |
C.The ant can't direct the newcomer. |
D.The ant will push the newcomer to the other route, so traffic jams won't form. |
4. What's the advice that Dr. Helbing gives us?
A.The cars cannot be allowed to communicate with traffic coming in the opposite direction. |
B.The cars can communicate with traffic in the same direction. |
C.The cars that travel in one direction can tell oncoming traffic about the traffic conditions. |
D.We should build more routes of different lengths and widths. |

Dreaming is believing, claim researchers of a new study, who found that dreams have an effect on people’s behavior, judgment and they might contain important hidden truths as well.
“Psychologists’ interpretations (解释) of the meaning of dreams vary widely. But our findings show that people believe their dreams provide meaningful insight (见识) into themselves and their world,” said a lead author of the study Carey More wedge, an assistant professor at Carnegie Mellon University.
In six different studies, researchers surveyed nearly 1,100 people about their dreams. One of the studies focused on general beliefs about dreams and involved 149 university students. All students were asked to rate different theories about dreams. The experts found that a surprising majority of the participants supported the theory about dreams revealing (揭示) the hidden truths about themselves and the rest of the world.
In a second experiment, they surveyed 182 people at a Boston train station, and asked them to imagine one out of four possible situations that could have occurred the night before a scheduled airline trip. Most of the participants said that dreaming of a plane crash would be more likely to affect their travel plans than would just thinking about a crash, or being warned by the government of a terrorism risk. They said a dreamed crash would influence their travel plans just as much as learning about a real crash on their planned route would.
Another experiment involved 270 men and women from across the United States. In a short online survey, they were asked to recall one of the dreams they had seen about any person they knew. The findings showed that people were more likely to remember and describe pleasant dreams about a person they liked, rather than a person they disliked. Meanwhile, in most cases they tended to consider an unpleasant dream as more meaningful if it was about a person they disliked.
“In other words,” said More wedge, “people attribute (归因于) meaning to dreams when it corresponds (与……一致) with their pre-existing beliefs and desires.” The researchers say that more investigation (研究) is needed to fully understand how people interpret their dreams. According to More wedge, most people realize that dreams are not predicting their future, but they still try to find some meaning in there.
1.The purpose of the studies is to _______.
A. determine when people tend to remember their dreams
B. research whether dreams have anything to do with real life
C. find out how people interpret their dreams and what impact that has
D. understand what causes people to dream and how to interpret dreams
2.According to the second experiment, what might influence people’s travel plans most?
A. Thinking about a past plane crash.
B. Dreaming about a plane crash.
C. Hearing a government’s warning of a terrorism risk.
D. Imagining a plane crashing on their planned route.
3.What can be concluded from the study?
A. When a dream conflicts with people’s existing beliefs and desires, they tend to attribute less
meaning to it.
B. Most people disagree that dreams help them better know themselves and the world.
C. A majority of people believes that dreams can predict their future and try to find their meaning.
D. Dreams can be a useful tool for learning and problem solving.
4.Which kind of dream is seen as more meaningful than the rest?
A. A pleasant dream about a person the dreamer likes.
B. A pleasant dream about a person the dreamer dislikes
C. An unpleasant dream about a person the dreamer likes.
D. An unpleasant dream about a person the dreamer dislikes.

The Peppered Moth, a kind of insect(昆虫), is found in England. It is light brown in colour and likes to settle(栖息) on trees which are also light brown. This makes the moth difficult to be seen and birds are less likely to notice and eat it.
But with the development of industry(工业) , smoke from factories began to reach the trees where the moth settled. It made the trees blacker. Then something very strange took place: in industrial areas, the Peppered Moth began to change colour. It became darker as well. Though the change took several years, some scientists soon notice that newly-born moths were a little darker than usual.
A scientist with the name Kettlewell decided to make a careful study of this phenomenon(现象). He marked some of the light moths and some of the darker ones, and set them free in the woods near Bermingham, an industrial city. Later, he recaptured(重新捕获) as many as the marked moths as possible. The results were as follows.
light moths | darker moths | |
Moths set free | 201 | 601 |
moths recaptured | 34(16%) | 206(34%) |
Kettlewell's research (研究) was done in the early 1950s. Soon afterwards Britain introduced new laws to reduce smoke and factory pollution.
Can you imagine what would happen to the Peppered Moth as the air became cleaner again?
1.The Peppered Moth began to change its colour in industrial areas because ________.
A.it itself liked to
B.it could be like the colour of its living-place
C.it had to keep the balance of nature
D.it was usually dark brown
2.From the results of Kettlewell's research, we can see that ________.
A.many more of the light moths were killed or eaten
B.more than one-fifth of the light moths was not killed
C.three times as many dark moths were kept safe as light ones
D.more dark moths were killed in industrial areas
3.As the air became cleaner, ________.
A.the number of the light moths became larger
B.the total number of the light moths remained unchanged
C.there were more of the darker moths and fewer of the light ones
D.the darker moths changed into the light ones suddenly

A team of researchers at the University of Illinois at Chicago found that too many kids are eating too much pizza and too many calories are doing harm to children’s health.
“There are a lot of takeaways from the study. But the biggest thing is that parents are serving their kids too much pizza,” said Dr.William Dietz, one of the study’s authors and the director of the Sumner M. Redstone Global Center for Prevention and Wellness at the Milken Institute of Public Health at the George Washington University.
The researchers used data from the National Health and Nutrition Examination Survey, which tracked the diets of more than 11,000 children and teenagers. Researchers figured how many children eat pizza in the United States, how often they eat it, and how much they eat when they do.
Pizza, pretty alarmingly, is the second leading source of calories in the diets of America’s children, next only to grain desserts, such as cookies and other sweets. On any given day, roughly 20 percent of all children aged 2 to 11 and adolescents aged 12 to 19 eat pizza. And when they do, they eat a lot of it. When children eat pizza, they eat roughly 400 calories, according to the study. For teenagers, it’s upwards of 600 calories.
All that is pretty problematic, according to Dietz largely because kids don’t tend to balance the pizza slices with salads, vegetables and other more nutritional(有营养的) foodstuffs. Days on which children and teenagers eat pizza are not only associated with considerably higher intakes of fat, but also, quite simply, with more food: on average, children consume 84 extra calories on the days they eat pizza, while adolescents consume an extra 230 calories.
“When you eat extra calories and don’t compensate(抵偿) for them at another point of the day or week, it can lead to weight gain and even obesity.”Dietz said.
There is a Silver lining. Pizza consumption is still too high by nutrition standards, but it’s lower than it used to be. Consumption(消费) fell by roughly 25 percent between 2007 and 2016, according to the study. Much of that has come at dinner where it's fallen by 40 percent for children and about 33 percent for teenagers. It’s unclear whether the decline has been in connection with a growing concern over obesity, especially among the country’s youth.
But the drop in pizza consumption, while significant hasn’t been big enough “It’s a positive trend,” Dietz said. “But we’re not quite them yet.”
It’s easy to see the appeal of pizza. It’s cheap. Parents can buy a lot of pizza for not a lot of money. Besides, they can buy pizza from a chain shop, a mom-and-pop store or a grocery freezer. And it’s universally loved. The estimated 3 billion pizza eaten each year in the United States is a proof of the food’s unmatched popularity. Given how much the country loves pizza, what’s to be done? Dietz suggests pizza with smaller serving sizes and healthier toppings(配料). “We’re not suggesting that kids avoid pizza altogether.” said Dietz. “But when parents serve it, it’s important that they understand it’s extremely caloric. They should serve smaller pizza, or at least smaller slices.”
1.According to the study, the problem with kids is that .
A. they are overweight B. they have too many takeaways
C. they are fed too much pizza D. they have very bad health
2.How did the researchers get the result?
A. Through interviewing. B. By analyzing data.
C. By tracking kids’ diets. D. Through experimenting.
3.We know from the passage that when kids eat pizza, .
A. they usually don’t eat other food B. they eat less of other food
C. they are not likely to balance their diet D. they usually eat with vegetables
4.What does the underlined part a silver lining in Paragraph 7 probably mean?
A. Something hopeful B. Something valuable.
C. Something miserable. D. Something successful.
5.What’s the key message of the last paragraph?
A. Pizza consumption fell significantly in America.
B. Pizza has many advantages over other food.
C. Eating too much pizza can lead to failing health and obesity.
D. The pizza problem may be improved through its size and topping.
