The World Wildlife Fund (WWF) says more than half of the world’s wildlife population has been lost, which the conservation group says has placed the health of the planet at risk.

The WWF recently released its 10th Flagship Living Planet Report. The group warns the condition of the world's animals is worse than its earlier reports showed, indicating worldwide action is needed.

The WWF is worried about the loss of and damage to Earth’s environment. The report provides information about more than 10,000 animal populations from 1970 to 2010. These populations are called “vertebrate species,” or animals with backbones — like fish, birds, mammals, amphibians and reptiles. The report shows these populations have dropped by 52 percent in just 40 years. It warns freshwater species have fallen by 76 percent, which is almost twice the loss of land and ocean species. Most of these losses are in the tropics, with the biggest drop in Latin America.

Marco Lambertini, the WWF’s International Director-General said, “This is about losing natural habitats. This is about converting forests, grasslands, and wetlands into agriculture mainly, and it is about unsustainable use of wildlife. Illegal hunting has been actually increasing over the last 10 years, which definitely a driving force for extinction, particularly of large species.”

The report also notes what it calls the world’s “Ecological Footprint”, that is, the effect of human activities on the planet. Mr. Lambertini says there has been an increase in carbon dioxide gases and the pouring of nitrogen into oceans and rivers from fertilizers used in agriculture, which certainly cannot continue.

“We are consuming on average every year about the equivalent of about 1.5, one and a half times the resources available to the planet. That means we are cutting trees more quickly than they can be restored. We are fishing the oceans more quickly than fishing stocks can reproduce, and we are emitting in the atmosphere more CO2 than the natural systems can actually absorb, which is clearly not sustainable.”

Mr. Lambertini warns climate change affects almost everyone on the planet and that whole species may disappear if the world does not reduce the effects of humans on the climate.

1.According to the passage, what kind of species faces the biggest drop in population?

A. Land and ocean species.

B. Animals with backbones.

C. Freshwater species in Latin America.

D. Freshwater species in the tropics.

2.All the following can contribute to the loss of world’s wildlife population EXCEPT ________.

A. turning wildlife habitats into agriculture land.

B. making sustainable use of wildlife.

C. hunting illegally.

D. emitting CO2 gases and pouring nitrogen.

3.Which does the underlined word “converting” in paragraph 4 mean?

A. Conserving.　　　 B. Conveying.

C. Exchanging.　　　 D. Transforming.

4.It can be inferred from the passage that _______.

A. Marco is much concerned about human’s current behaviors towards wildlife.

B. what the planet provides now can satisfy human’s sustainable development.

C. more than half of the world’s wildlife population has been lost.

D. if humans reduce the effects on the climate, the whole species will not disappear.

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 statement of researchers who have found that tapping away on a mobile phone or computer keypad or checking for electronic messages temporarily knocks up to 10 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 described the phenomenon of improved stupidity as “infomania”. The research conducted by Hewlett Packard, the technology company, has concluded that it is mainly a problem for adult workers, especially men.

It is concluded that too much use of modern technology can damage a person’s mind. It can cause a 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 task in hand. The report also added that, in a long term, the brain will be considerably shaped by what we do to it and by the experience of daily life. At a microcellular level, the complex networks of nerve cells that make up parts of the brain actually change in response to certain experiences.

Too much use of modern technology can be damaging not only to a person’s mind, but to their social relationship. 1100 adults were interviewed during the research. More than 62 per cent of them admitted that they were addicted to checking their e-mails and text messages so often that they scrutinized work-related ones even when at home or on holiday. Half said that they always responded immediately to an email and will even interrupt a meeting to do so. It is concluded that infomania is increasing stress and anxiety and affecting one’s characteristics. Nine out of ten thought that colleagues who answered e-mails or messages during a face-to-face meeting were extremely rude.

The effects on IQ were studied by Dr Glenn Wilson, a psychologist at University of London. “This is a very real and widespread phenomenon,” he said. “We have found that infomania will damage a worker’s performance by reducing their mental sharpness and changing their social life. Companies should encourage a more balanced and appropriate way of working.”

1.We can learn from the passage that “infomania” ______.

A. has a positive influence on one’s IQ

B. results in the change of part of the brain

C. lies in the problem of lack of concentration

D. is caused by too much use of modern technology

2.The research mentioned in the passage is most probably about ______.

A. the important function of advanced technology

B. the damage to one’s brain done by unhealthy habits

C. the relevance between IQ and use of modern technology

D. the relationship between intelligence and working effectiveness

3.The underlined word “scrutinized” probably means “______”.

A. examined carefully　　　　 B. copied patiently

C. corrected quickly　　　　 D. admitted freely

4.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. The regular use of text messages and e-mails can harm your IQ.

C. Modern technology can damage a person’s mind.

D. Electronic messages have side effects on the user’s life.

★The regular use of text messages and e-mails can lower the IQ more than twice as much as smoking marijuana(大麻). Psychologists say that sending/receiving messages or looking through the many menu options your mobile phone has, lowers a person’s IQ by almost 10 points. British researchers have named this situation “infomania”. Instead of fixed on what they are doing, people’s minds are constantly focused on reacting to the technology surrounding them. This means they don’t pay full attention to the work they are paid to do. The report also added that the brain can not do so many things at once. If you try to do too many things, mistakes begin to occur. And while modern technology can have huge benefits, too much use can be damaging not only to a person’s mind, but to their social life.

★The more televisions 4-year-old children watch, the more likely they are to become bullies later on in school, a newest U.S. study said. At the same time, children whose parents read to them, take them on outings and just generally pay attention to them are less likely to become bullies, said the  report from the University of Washington. Researchers also found gaps in learning and understanding such things as social skills early in life makes it more difficult for children to relate with other children. Watching violence on television leads to aggressive behavior.

★You could soon be able to add your favorite perfume to your e-mails. UK net provider Telewest Broadband is testing a system to let people send e-mails over the Internet with sweet smell. It has developed a kind of hi-tech air freshener that plugs into a PC and sprays a smell linked to the message. Telewest says it could be used by supermarkets to attract people with the smell of fresh bread or by holiday companies seeking to stir up images of sun-kissed beachers.
