SINGAPORE - Singapore on Thursday stuck to its I8-year ban on the import and sale of chewing gum (口香糖), which has become an international symbol of the city-state's image as a strict society.
"The government stands by its decision to ban chewing gum. Chewing gum has not been a significant problem since that ban took effect, there have been concerns that lifting the ban on chewing gum could result in chewing gum litter and weaken ongoing efforts to control littering." Maliki Osman, parliamentary secretary at the Ministry of National Development, told parliament.
Osman said as the reason for the imposition (强迫接受) of the ban is still suitable, "the government's position is that the ban shall remain." He was responding to a question in parliament from Denise Phua, a fellow member of the ruling People's Action Party who argued that the ban had been used to criticize its tough governance laws.
"I think this ban ... now needs a re-thinking. Surely Singapore will not consider banning sweets because of sweet wrapper litter or ice-cream stick litter," she said.
Singapore, known worldwide for its high-quality clean image, banned the import and sale of chewing gum in 1992 in a bid to cope with the problem of people sticking the gum on chairs, tables, lifts and other public areas.
One of the key reasons for the ban had been the disturbance of services on Singapore's subway train system because of chewing gum being stuck on the doors and causing delays. Singapore partially lifted the ban in 2004 by allowing the sale of chewing gum used for health reasons, such as dental health gum, after the conclusion of a US-Singapore Free Trade Agreement.
Australian tourist Hazel Lane, 48, said keeping the ban on chewing gum was sure Singaporeans wouldn't want to spoil their "ridiculous" and she told AFP that she's own environment and their own image. Angel Wong, 34, a tourist from Hong Kong, however, welcomed the news. She said, "I come from a country that doesn't have the ban and there's always chewing gum all over the floor, To me the ban doesn't change my image of Singapore so it’s a good thing because it keeps the environment clean."
1. The ban on the import and sale of chewing gum was started in 1992 ______.
A. when people began to buy the gum everywhere
B. to bid to stop people sticking the gum in the public
C. because the gum delayed the subway
D. when the country was in a bid to show its city-state's clean image
2. What can we learn about the ban according to Maliki Osman?
A. The government will keep it ongoing forever.
B. It will lead to littering the chewing gum everywhere.
C. More and more concerns about the ban will make chewing gum out of control
D. Banning chewing gum is still one of the important jobs of the government now.
3. According to what Denise Phua said in paragraph 4, we can know that she ______.
A. would say yes to the ban
B. would think more about the ban again
C. would like the government to take the ban on second thought
D. argued that the ban should be cancelled
4. It can be inferred from the passage that ______.
A. whether the ban needs changing or not has become a problem to be discussed
B. Singapore's subway train system was delayed by chewing gum
C. chewing gum will soon be banned in many countries
D. only the ban has led to the friendly environment in Singapore
5. What's the main idea of the last paragraph?
A. There is such a ban in China and Australia.
B. Different people have their own ideas about the ban.
C. The ban is either welcomed by China or by Australia.
D. The ban does good to keep the environment clean.

Millions of people die of hunger in southern Africa every year, but when Zambia was offered thousands of tons of free maize by the US, the government politely said no.

“We don’t know whether the food is safe,” said Zambia’s commerce, Trade and Industry Minister Dipak Patel.

His worries are shared by countries around the world that are in two minds about America’s genetically modified（GM,转基因的）crops．Just last week, EU（欧盟）member nations were discussing whether or not to import GM sweet corn from the US．

Ever since people started farming, they have tried to crossbreed（杂交）plants to make them stronger or better tasting. At one time, only related plants could be crossed with each other．

But when GM techniques were developed in the 1970s, scientists were able to put a single gene from a living creature into an unrelated creature.

This means they can make crops more productive and resistant to disease by adding genes from other species．They can also create food with special characteristics, such as “golden rice”, which is enriched with vitamin A. But many people believe GM foods are a health risk.

At the moment, the official argument is that GM foods “are not likely to present risks for human health”. But there are still many questions to be answered as the foods are produced in different ways.

Some experts believe the genetic material added to plants can transfer to humans and give damage to our bodies. Further harm could be caused by the genes from GM plants crossbreeding with naturally produced crops．

People in China are also getting worried about GM foods. More than 70 percent of the

country’s soybean oil is produced from imported GM soybeans. Meanwhile, an investigation last November found that 12 of 60 famous foods sold across the country were GM products. The government has begun to introduce a marking system for GM goods so that people can choose whether or not to eat them.

1.Which is the best title for the passage?

A. Harmful GM foods B. Advantages of GM foods

C. GM foods, a health risk? D. the Techniques of GM foods

2.Why has Zambia refused the American free maize?

A. they decide to follow EU member’s advice

B. they are concerned about the safety of GM foods

C. they care little about the problem of starvation

D. they are too proud to accept free offer

3.It has been proved that _________.

A. GM foods are harmful to people’s health

B. GM food is no better than naturally produced foods

C. only related plans could be crossed with each other

D. GM techniques can increase the production of crops

4.Which of the following statement is TRUE?

A. GM foods are a health risk.

B. Only Zambia worries about the safety of GM foods .

C. China’s government hasn’t taken any action about GM foods.

D. Some experts believe human bodies can absorb genetic material from GM foods.

5.What’s the author’s attitude towards GM foods?

A. Supportive. B. Neutral. C. Doubtful. D. Critical.
