It is a tall tale（夸张的故事）that terrifies most young children. Swallow a piece of chewing gum and it will remain in your body for seven years before it is digested. An even worse tale is that swallowed（吞） gum can wrap itself around your heart.

But what does happen if you should accidentally eat a stick of gum? Chewing gum is made out of gum base, sweeteners, coloring and flavoring. The gum base is pretty indigestible(难消化的)—it is a mixture of different ingredients (成分) that our body can't absorb.

Most of the time, your stomach really cannot break down the gum the way it would break down other foods. However, your digestive system has another way to deal with things you swallow. After all, we eat lots of things that we are unable to fully digest. They keep moving along until they make it all the way through the gut (肠子) and come out at the other end one or two days later.

The saliva (唾液) in our mouths will make an attempt at digesting chewing gum as soon as we put it in our mouths. It might get through the shell（壳） but many of gum's base ingredients are indigestible. It's then down to our stomach muscles—which contract(收缩) and relax, much like the way an earthworm moves—to slowly force the things that we swallow through our systems.

Swallowing a huge piece of gum or swallowing many small pieces of gum in a short time can cause a blockage within the digestive system, most often in children, who have a thinner digestive tube than adults—but this is extremely rare.

1.Children might feel terrified after swallowing chewing gum mainly because ________.

A．they believe the tall tales about chewing gum

B．chewing gum will stay in their body for years

C．their heart will be wrapped by chewing gum

D．chewing gum is indigestible for children

2.What happens to the food that can't be fully broken down?

A．It remains in our digestive system forever.

B．It will be eventually moved out of our body.

C．It will fight against the power of the gut.

D．It will stick to the gut for one or two days.

3.The word It (in the 4th paragraph) refers to “________”.

A．the attemptB．the salviaC．the shellD．the gum base

4.What would be the best title for text?

A．How does our digestive system work?

B．Can chewing gum be swallowed by kids?

C．Does swallowing chewing gum matter?

D．Why swallowing chewing gum frightens kids?

Australia has promised to introduce the most comprehensive （全面的） carbon trading program outside Europe in 2010. The government in Canberra plans to cut greenhouse gas emissions (排放) by at least five percent by 2020, but it could make bigger reductions if other countries agree to tougher targets.

The Australian government warns that without tough environmental measures the country could lose key industries and jobs. Climate Change Minister Penny Wong says the economy is under threat and decisive action is needed.

Central to the government’s climate change plan is a carbon emissions trading program that will be introduced within two years. It would involve one thousand of the nation’s biggest companies and would cover about three-quarters of Australia’s greenhouse gas emissions.

Many scientists believe that greenhouse gases, such as carbon dioxide and methane, contribute to global warming. Many of them are released by burning fuels such as coal and oil.

Companies will be required to buy permits for each ton of carbon they emit, although big polluting exporters will receive up to 90 percent of their carbon licenses free.

Many business leaders want the government to delay the plan because of the current global financial crisis, which is slowing the Australian economy. Peter Anderson from the Australian Chamber of Commerce and Industry says it is irresponsible to bring in a carbon trading plan now.

Environmentalists, on the other hand, say Prime Minister Kevin Rudd has not properly addressed the threat of climate change. Activists had sought a minimum emissions cut of 25 percent.

Instead, the Rudd government aims to cuts carbon emissions by at least five percent of 2000 levels by 2020. That amount could rise to 15 percent, if future global agreements set such a target.

Ray Nias of the environmental group WWF says Australia will pay the price for low targets. “This is a deeply, deeply disappointing target,” Nias said. “It commits Australia to long-term climate change. It will make Australia’s ability to negotiate (协商) global agreements very, very difficult. It is much lower than even we had imagined.”

Australia has one of the highest per-person greenhouse emissions rates in the world because of its reliance on coal for electricity.

Some scientists warn that the vast, dry Australian continent, which has been suffering a series of droughts in recent years, could be one of the region’s hardest hit by global warming.

1.Which group supports to cut carbon emissions by at least 25%?

A. Environmentalists.B. The government.

C. Business leaders.D. Scientists.

2.Who most probably agrees to a higher goal of carbon emissions?

A. Penny Wong.B. Peter Anderson.

C. Kevin Rudd.D. Ray Nias.

3.Many business leaders are against the Australian program because ________.

A. they believe the program will only benefit the big companies

B. they believe the program will cause the global warming

C. they don’t want to pay extra money for carbon emissions

D. they don’t think carbon emission will surely cause the global warming

4.The underlined sentence means ________.

A. The Australian government will be blamed for the low target

B. Australia will suffer a lot from climate change caused by carbon emissions

C. The Australian government will have to spend lots of money on carbon emissions

D. Many Australian companies will close down because of the low target

Teenagers around the world can be glad with the news that their brain deserves the blame when parents’ orders go ignored while they tap on their smartphones.

A new scientific study from the University College London has found that humans may suffer temporarily deaf when they’re simultaneously focusing on something visual. Research found that the 13 volunteers experienced inattentional deafness to the normal-volume sounds playing in the background as their visual tasks became increasingly difficult. ‘We found that when volunteers were performing the demanding visual task, they were unable to hear sounds that they would normally hear,’ study co-author Maria Chait said in a statement. ‘The brain scans showed that people were not only ignoring or filtering out the sounds, they were not actually hearing them in the first place.’

The findings, published in the Journal of Neuroscience, suggest that the visual and auditory processing centers that make sense of the sights and sounds that surround us share limited resources.

Inattentional deafness is a common everyday experience and the study explains why, according to UCL Institute of Cognitive Neuroscience Professor Nilli Lavie, a co-author of the study. ‘This could also explain why you might not hear your bus or train stop being announced if you’re concentrating on your phone, book, or newspaper. ’‘If you try to talk to someone focusing on a book, game, or television program and don’t receive a response, they are not necessarily ignoring you, they simply might not hear you! ’ she said.

Loud sounds—like ambulance sirens—will still be able to break through, but some situations could become potentially dangerous when the quieter ones go unheard, according to Medical Daily. ‘This has more serious implications in situations such as the operating theater, when a surgeon concentrating on their work might not hear the equipment beeping,’ Lavie said. ‘It also applies to drivers concentrating on complex directions as well as cyclists and motorists who are focusing intently on something such as an advertisement or even simply an interesting-looking passerby.

A. experienced deafness due to their inattention

B. were deaf to the normal sounds intentionally

2. If a person concentrates on a book______

A. you cannot expect him to respond to you

B. he doesn’t want to give you a reply

C. he wants you to be away from him

D. he may get angry because of your disturbance

3.How does the inattentional deafness affect our life according to the last paragraph?

A. It may lead to people losing friends.

B. It may cause danger in some fields.

C. It may make something more complex.

D. It may increase one’s attraction.

4.What does the passage mainly want to tell us?

A. The benefit of the inattentional deafness

B. The expectation from young teenagers.

C. Concentrating on something visual can cause short deaf ears

D. Inattentional deafness is not a good thing
