The regular use of text messages and e-mails can lower the IQ more than twice as much as smoking marijuana（大麻）. That is the claim of psychologists who have found that tapping away on a mobile phone or computer keypad or checking them for electronic messages temporarily knocks up to ten points off the user’s IQ.
This rate of decline in intelligence compares unfavorably with the four-point drop in IQ associated with smoking marijuana, according to British researchers, who have labeled（把……称为）the fleeting phenomenon of enhanced stupidity as “infomania”.
The noticeable drop in IQ is believed to be the result of the constant distraction of “always on” technology when employees should be concentrating on what they are paid to do. Infomania means that they lose concentration as their minds remain fixed in an almost permanent state of readiness to react to technology instead of focusing on the tasks in hand.
The brain also finds it hard to deal with keeping lots of tasks in motion at once, reducing its overall effectiveness. While modern technology can have huge benefits, excessive(过度的)use can be damaging not only to a person’s mind, but to his or her social life.
Eighty volunteers took part in clinical trials on IQ damage and 1,100 adults were interviewed.
More than six in ten people polled admitted that they were addicted to checking their e-mail and text messages so that they examined work-related ones even when at home or on holiday. Half said that they always responded immediately to an e-mail and one in five would interrupt a meeting to do so.
Furthermore, infomania is having a negative effect on work colleagues, increasing stress and disagreeing feelings. Nine out of ten polled thought that colleagues who answered e-mails or messages during a face-to-face meeting were extremely rude. Yet one in three Britons believed that it was not only acceptable, but actually diligent and efficient to do so.

Studies show that children who eat breakfast do better in school. It doesn’t take much further thought to know that adults will feel better and do better at work as well. Whether you work at home, on the farm, at the office, at school, or on the road, it is not a good idea to have no breakfast.
If we have no breakfast, we are likely to become tired when our brains and bodies run low on fuel (食物). By mid-morning, a lot of us grab a cup of coffee or eat a sugary candy bar to wake up again. This might work for a few minutes, but by lunch time we are hungry. Eating a good breakfast sets the tone for the rest of the day.
Having no breakfast is a popular way to lose weight, but not a smart one. Many people believe that they will lose weight if they have no meals, but that just isn’t true; the body expects to be refueled a few times a day, starting with a healthy breakfast. Eating breakfast is good for losing weight. In fact, people who eat breakfast are more likely to keep a healthy weight.
A healthy breakfast should have some protein (蛋白质) and some fiber (纤维). Protein can come from low fat meats, eggs, or beans. Fiber can be found in whole grains, vegetables and fruits. A good example of a healthy breakfast might be something simple like a hard boiled egg, an orange, and a bowl of whole grain cereal with low fat milk. Stay away from sugary foods and white bread because they are digested (消化) quickly and will leave you hungry and tired in several hours. Protein and fiber will keep you feeling full until lunch time. The first paragraph mainly tells us that ______.
| A．it is necessary to have a good breakfast every day |
| B．many adults are too busy to have breakfast every day |
| C．many adults go to work without having breakfast |
| D．many children go to school without breakfast |
According to the passage, we feel tired at work probably because __.
| A．we need to have a cup of coffee | B．we don’t have a good breakfast |
| C．our brains don’t work any longer | D．we don’t have enough sleep at night |
What does the underlined sentence in Paragraph 2 mean?
| A．Having a good breakfast can help you to finish your work. |
| B．Eating a good breakfast is enough for the whole day. |
| C．Breakfast is really the most important meal in a day. |
| D．You will be happier if you have a good breakfast. |
We can learn from the last paragraph that ______.
| A．it is healthy only to have beans and eggs for your breakfast |
| B．you mustn’t have meat for your breakfast |
| C．you should eat sugary foods if you feel hungry |
| D．you should eat something which has protein and fiber for breakfast |
At some point I noticed that people were staring at me. The box boys at the supermarket spoke to me with respect. People were mistaking me for somebody else. It had to be somebody who weighed close to 300 pounds and wore a full beard. I enjoyed the way people would suddenly turn to look at me as if I wore wings. Nobody mentioned my name， but naturally they assumed I knew who I was. I could hardly ask， “By the way， who am I？”
As a result of being in the public eye， I began to change myself. I kept my shoes shined. Also， I changed shirts every day. The more I changed， the more second looks I received. From enjoying the attention， I began to long for it. I’d always felt I was somebody special. Now others were finally realizing it.
But who did people think I was？ I must have been a movie star， or at least a television personality. Then one evening I was sitting at a bus stop in Westwood Village when two young men in an old car looked up at me with that expression I had come to recognize as a respect to my talent and success. One of them said， “Hello， Dom！” So that was who I was！ Once I imagined that well-known comedian， I realized I couldn’t have been anybody else. I gave my young fans a big celebrity grin and said， “Hello， boys！” I waved one hand with a welcome-to-Hollywood gesture they would be talking about for years.
I also realized that it was time to go on a diet. I ate more salads and vegetables. I laid off the carbohydrates. I walked a couple of miles every day. When I had lost about 40 pounds， I shaved off my beard. I didn’t realize that my barber had actually been trying to make me look like the fat Dom DeLuise. I waited for my clients to ask， “What did you do to yourself？” But nobody even noticed a change. I melted back into the general population.Why was the author mistaken by people for somebody else？ (No more than 11 words) (2 marks)

Educating girls quite possibly harvests a higher rate of benefit than any other investment available in the developing world. Women’s education may be an unusual field for economists， but increasing women’s contribution to development is actually as much an economic as a social issue. And economics， with its focus on rewards， provides an explanation for why so many girls are deprived of(剥夺)an education.
Parents in low-income countries fail to invest in their daughters because they do not expect them to make an economic contribution to the family： girls grow up only to marry into somebody else’s family and bear children. Girls are thus seen as less valuable than boys and are kept at home to do housework while their brothers are sent to school — the predict becomes self-ffulfilling， trapping women in a vicious circle (恶性循环) of neglect.
An educated mother， on the other hand， has greater earning abilities outside the home and faces an entirely different set of choices. She is likely to have fewer but healthier children and can insist on the development of all her children， ensuring that her daughters and sons are given fair chances. The education of her daughters then makes it much more likely that the next generation of girls， as well as of boys， will be educated and healthy. The vicious circle is thus transformed into a virtuous circle(良性循环).
Few will argue that educating women has great social benefits. But it has enormous economic advantages as well. Most obviously， there is the direct effect of education on the wages of female workers. Wages rise by 10 to 20 per cent for each additional year of schooling. Such big returns are impressive by the standard of other available investments， but they are just the beginning. Educating women also has a significant impact on health practices， including family planning.

US military is attempting to develop a new style “insect robot” to replace the human soldier to go wherever he can’t. The greatest trouble this project has fallen across is how to enable the robot to fly freely like an insect， said an official of the Pentagon(五角大楼).
The Pentagon is seeking for the cooperation with scientists in hope of developing a new technique by which people can control the insect’s flight direction and pass on the information its eyes or other organs catch through the equipment set in its body， the official said.
It is thus designed that a tiny controlling chip will be equipped in an insect’s body when it is in chrysalis(蛹). As the insect grows， the cut made when fixing in the chip will be recovered. The chip will exist in forever. Scientists believe this won’t influence the insect， sound growth or the functions of internal organs.
The terminal target of the project is to set up a global system， in which the insect robots will be stationed in all parts of the world and stick to their posts till a new instruction is received. At that time the military can receive from all over the world clear image information within about 5 meters of the insects and that of a special target within 100 meters.
Years ago， Defense Advanced Research Projects Agency of US DOD(国防部) spent $3,000,000 carrying out a plan for training bees to detect landmines. But， no new progress has so far been made.
“According to the scientists， there is still enormous difficulty in technology in turning it into reality， such as the insects reproduction(繁殖)， their adaptation to the surroundings and temperature and so on. However， this project is really challenging. If successful， it is equal to making countless small drone(无人机)，”said the official of DOD.According to the description of the passage， what is an insect robot like？

As for the design that an insect robot can receive and send information， how do you infer(推测) it works？
| A．There must be a controlling chip well connected with the insect’s brain. |
| B．The insect’s eyes and other organs must be replaced by some special equipment. |
| C．All the insect’s concerned organs must be controlled by a chip. |
