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.
67. What does the underlined part mean?
A.A person’s IQ drops ten points if he or she always checks electronic messages.
B. The person who has a higher IQ enjoys checking electronic messages.
C. The person who has a lower IQ enjoys checking electronic messages.
D. A person’s IQ is ten points higher if he or she always checks electronic messages.
68. What happens to people with infomania?
A. People with infomania can only concentrate on their tasks in hand.
B. people with infomania are addicted to smoking marijuana.
C. People with infomania can’t respond to technology immediately.
D. People with infomania can’t concentrate on their tasks in hand.

A. about 550 interviewees responded to an e-mail immediately
B. about 670 interviewees responded to an e-mail immediately
C. about 50 taking part in clinical trials on IQ were addicted to checking e-mails
D. about 16 taking part in clinical trials on IQ refused to answer e-mails immediately
70. What is the main idea of this passage?
A. The regular use of text messages and e-mails can be compared to smoking marijuana.
B. Modern technology can damage a person’s mind.
C. The regular use of text messages and e-mails can harm your IQ.

Sudan1 is a red industrial dye that has been found in some chilli powder, but was banned in food products across the European Union (EU) in July 2003.
Since the ban was put in place, EU officials have been striving to remove some food products from the shelves. So far 580 products have been recalled.
Last week Sudan’s Embassy in the United Kingdom asked the Food Standards Agency (FSA) for clarification of the origin of the dye’s name.
Omaima Mahmoud Al Sharief, a press official at Sudan’s Embassy in China, explained the purpose of the inquiry was to clear up any misunderstanding over links between the country and the poisonous dye.
"We want to keep an eye on every detail and avoid any misunderstanding there," she said. "Our embassy to Britain asked them how the dye got that name and whether the dye had something to do with our country. But they told us there was no relationship."
The FSA, an independent food security watchdog in Britain, received a letter from the Sudanese embassy last week.
"They asked us why the dye is named Sudan, however, we also do not know how it got the name," she said. "People found the dye in 1883 and gave it the name. Nobody knows the reason, and we cannot give any explanation before we find out."
Sudan dyes, which include Sudan1 to 4, are red dyes（颜料） used for colouring solvents（溶剂）, oils, waxes, petrol, and shoe and floor polishes. They are classified as carcinogens by the International Agency for Research on Cancer.

| A．The dye is often produced in Sudan. |
| B．The dye has something to do with the country named Sudan. |
| C．Nobody is sure of the origin of the name. |
| D．Many foods produced in Sudan contain the dye. |

People who bought wine at the store were also more likely to buy fruit, vegetables, fish, lean meat (瘦肉) and milk than beer buyers did, said the study.
Beer buyers were more likely to buy frozen dinners, cold cuts, pork, sugary products, and soft drinks.
The study was conducted by four researchers from the National Institute of Public Health over the course of six months.
Alcohol researchers Erik Schulenburg and Marten Greenback and two other doctors collected 3.5 million receipts from 98 stores. The customers at the stores represented a large number of Danish people, they said.
“Our results confirm international studies which show that wine drinkers tend to eat more fruit, vegetables and fish and rarely eat fats, compared to those who like other kinds of alcoholic drinks,” they concluded.
Wine buyers also tended to have higher education levels, higher earnings and be in better mental health, they added.
Their interest in consumers’ shopping bags followed a series of studies in the Danish media. The studies suggested that wine drinkers ran a lower risk of cardiovascular (心血管的) disease and some types of cancer than beer drinkers.
小题1:The passage mainly tells us that wine drinkers ______.
| A．eat more vegetables than beer drinkers |
| B．usually buy healthier food than beer drinkers |
| C．are mostly healthier than beer drinkers |
| D．run a lower risk of diseases than beer drinkers |
| A．cold cuts | B．pork | C．soft drinks | D．vegetables |
| A．handing out papers with a list of questions |
| B．collecting receipts from stores |
| C．watching what customers bought at stores |
| D．visiting some families throughout the country |
| A．Rarely eating fats. | B．Being in better mental health. |
| C．Exercising more. | D．Having higher education levels. |
The first kind of loneliness is temporary. This is the most common type. It usually disappears quickly and does not require any special attention. The second kind, situation－for example, family problem, the death of a loved one, or moving to a new place. Although this kind of loneliness can cause physical problems, such as headaches and sleeplessness, it usually does not last for more than a year.
The third kind of loneliness is the most severe. Unlike the second type, chronic (the opposite of “temporary”) usually lasts more than two years and has no specific cause. People who experience habitual loneliness have problems socializing and becoming close to others. Unfortunately, many chronically lonely people think there is little or nothing they can do to improve their condition.
Psychologists agree that one important factor in loneliness is a person’s social contacts, for example, friends, family members, co－workers, etc. we depend on various people for different reasons. For instance, our families give us emotional support, our parents and teachers give us guidance, and our friends share similar interests and activities. However, psychologists have found that, though lonely people may have many social contacts, they sometimes feel they should have more. They question their popularity.
Psychologists are trying to find ways to help habitually lonely people for two reasons: they are unhappy and unable to socialize and there is a connection between chronic loneliness and serious illness such as heart disease, while temporary and situational loneliness can be a sad, and sometimes dangerous condition.
小题1:How would you treat temporary loneliness according to the passage?
| A．Talk to friends. | B．Just ignore it. |
| C．Go to see a doctor. | D．Ask your teachers for guidance. |
| A．temporary loneliness | B．situational loneliness |
| C．a new place | D．sleeplessness |
| A．Chronic loneliness can cause family problems. |
| B．Chronic loneliness can cause serious illness |
| C．Chronic loneliness can not be overcome. |
| D．Chronic loneliness is incurable. |
| A．Three kinds of loneliness | B．Loneliness and disease |

On January 28, 1958, a man named Godtfred Kirk Christiansen created the plastic building bricks that can now be found in almost every child’s toy box. The simple building block has become one of the most well-known and popular toys around the world.
"The Lego brick continues to be very attractive, because it allows children, and others, to develop their creativity and imagination," said Charlotte Simonsen, a spokeswoman of the Danish Lego company.
The company’s building brick allows an infinite number of links. With just two bricks there are 24 different links, and with six, there are 915 million possibilities, according to Lego.
A half-century after its creation, more than 400 million children and adults spend five billion hours a year putting the bricks together and pulling them apart. Also, the bricks made today can still interlock with those made in 1958.
Lego bricks are not just child’s play: they also attract the interest of adults. South Korean adventurer, Heo Young-Ho, who climbed Mount Everest in 1987, left a Lego toy behind in the snow during his climb.
After its great success Lego experienced a severe crisis at the end of the 1990s, hit hard by fierce competition from electronic games. This so-called "Toy of the Century" then suffered a dark period that lasted several years.
With great efforts, the company began to prosper again, and in 2006 it earned about 1.5 billion dollars in 130 countries. Seven boxes of Lego are now sold every second around the world, and 19 billion bricks are produced each year: enough to encircle the Earth five times！

Green symbolizes life, health and energy. Nowadays, people demand healthy and fresh food. Having enough food to eat is only a basic requirement, and they need more than this. They want to enjoy unpolluted, safe and nutritious food and eat comfortably. So the government does this through a set of “from the land to the dinner table” quality controls. It requires to change China’s traditional agricultural structures and ensure the food of high quality.
Safe vegetables refers to products without substances harmful to humans. Growing such vegetables requires no strong poisons, thus guaranteeing vegetables fresh and clean. There are strict regulations in place for even applying fertilizer(肥料). The examination of vegetables should reach the state food hygiene(卫生) standard. The following conditions for green food are regulated by the China Green Food Development Center. Firstly, products or raw materials must reach the green ecological environment standard set by the Ministry of Agriculture. Secondly, crop planting, livestock raising, fish breeding and food processing must follow green food operating procedures set by the Ministry. Products must be up to the green food hygiene standard. External packing must be pasted with national standard universal labels, special green food packing decoration and tag regulations.
However, by now, our goal hasn’t been completely realized. When you return home with a full basket, you are still worried about whether what you have bought is green and healthy. Indeed, for the sake of our health, we still have a long way to go.
