Feed the world

With the global population expected to rise to 9 billion within 50 years, feeding the world has never seemed such a daunting task. But GM(转基因)technology is giving hope to developing countries, where many people think biotechnology can offer improved nutrition, health and prosperity(繁荣).

High hopes

Many scientists in Africa regard GM crops as the only way to avoid mass starvation (饥饿) on the continent. Kenyan researchers recently created a GM sweet potato that they predict could increase yields by up to 80 percent.

Meanwhile, South African scientists have used genetic modification to insert the vaccine (疫苗) for the disease cholera (霍乱) into bananas. Cholera is a particularly serious problem in South Africa. But there are still several barriers that stop developing countries from growing GM crops on a large scale.

Obstacle course

Private enterprise is unwilling to invest in GM products that would benefit developing countries. Regulatory clearance (许可证) to grow a single GM crop can cost companies between $5 (￡3.4 million) and $30 million (￡20.5 million), so they tend to focus on areas that give them large returns on their investment.

Use only once

In traditional farming, some seeds from a harvest are saved to be planted the following year. But biotech companies force farmers growing GM crops to buy new supplies of seed every harvest. Farmers in Canada have even been sued(控告)for re-planting GM seed.

But biotech companies think it will be harder to enforce this rule in developing countries, so they have been coming up with cunning(狡猾的)methods to make farmers come back for seed each year.

This approach could make farmers too dependent on such companies for their livelihoods, leading them to neglect the basic farming skills they would need to rely on if their situation changed and possibly bankrupted (破产) them.

Going it alone

Developing countries are making real progress in genetic engineering, and have already produced their own GM crops. But many environmentalists are worried that developing nations would not apply strict testing to GM crops and food safety regulations (规章).

5. From the first paragraph we know that ________.

A. food supply for the whole world is out of question because of GM technology

B. food supply for the whole world is still a serious problem because of the increasing of population

C. food supply for the whole world is never a problem because of biote chnology

D. people in developing countries will never have food shortage because of GM technology

6. The purpose of growing GM crops is ________.

A. to provide safer food for the world

B. to find a new cure to the disease cholera

C. to get a lot of money by selling the seeds

D. to prevent the world from mass starvation

7. Some enterprises are unwilling to spend money on GM products because ________.

A. the products will benefit developing countries

B. they have to pay a large amount of money to get the permit

C. they don't have much knowledge about the GM technology

D. they can't get enough seeds from the biotech companies

8. It can be inferred that________.

A. growing GM crops would possibly make farmers bankrupt

B. companies could grow GM crops freely once they had the GM technology

C. developing countries are growing GM crops on a large scale

D. scientists are not sure about whether GM crops are safe to eat

If you are a male and you are reading this ,congratulations: you are a survivor. According to statistics, you are more than twice as likely to die of skin cancer than a woman ,and nine times more likely to die of AIDS. Assuming you make it to the end of your natural term, about 78 years for men in Australia, you will die on average five years before a woman.

There are many reasons for this-typically, men take more risks than woman and are more likely to drink and smoke but perhaps more importantly, men don’t go to the doctor. “Men aren’t seeing doctors as often as they should, ” says Dr. Gullotta, “This is particularly so for the over-40s,when diseases tend to strike.” Gullotta says a healthy man should visit the doctor every year or two. For those over 45,it should be at least once a year. Two months ago Gullotta saw a 50-year-old man who had delayed doing anything about his smoker’s cough for a year. “When I finally saw him it had already spread and he has since died from lung cancer” he says, “Earlier detection and treatment may not have cured him, but it would have prolonged this life”

According to a recent survey, 95%of women aged between 15 and early 40s see a doctor once a year, compared to 70% of men in the same age group. “A lot of men think they are invincible （不可战胜的）” Gullotta says “They only come in when a friend drops dead on the golf course and they think “ if it could happen to him. Then there is the ostrich approach,” some men are scared of what might be there and would rather not know, ” says Dr. Ross Cartmill.

“Most men get their cars serviced more regularly than they service their bodies,” Cartmill says. He believes most diseases that commonly affect men could be addressed by preventive check-ups

Regular check-ups for men would take time and money of the public, Cartmill says.” But prevention is cheaper in the long run than having to treat the diseases. Besides, the ultimate cost is far greater: it is called death.”
