Australians have been warned they face a life or death decision over their water — drink recycled sewage (污水) or die.

With t he drought (干旱) continuing, the country is set to be forced to use purified (净化的) waste water for drinking, even though there is great opposition to the measure.

Queensland has become the first state to introduce the policy after a warning from its premier .

 "I think in the end, because of the drought, all of Australia is going to end up drinking recycled purified water," said Peter Beattie.  

 "These are difficult decisions, but you either drink water or you die. There's no choice. It's liquid gold, it's a matter of life and death."

Beattie said Australia's second largest state would become the first to use recycled water for drinking.

Water is recycled in Britain and parts of northern Europe along with the US and Israel.

But Australians have never liked the idea.

To try to change the way Australians think, Prime Minister John Howard and Environment Minister Malcolm Turnbull have adhered to Queensland's move.

"I am very strongly for recycling and Mr. Beattie is right and I agree with him completely," Howard said.

“Australian cities, all now facing water shortages because of the worst drought on record, must start to use recycled water.” added Turnbull, "All of our big cities have to widen the range of water sources to include sources which are not dependent on rainfall."

What is the text mainly about?

A. Continuing drought forces Australians to drink recycled sewage

B. Australians face the choice of life and death

C. Premier Beattie is worried about his people’s health

D. We should avoid drinking recycled water to keep healthy

According to the passage, which of the following is TRUE?

A. Nobody disagrees to the idea of drinking recycled purified water

B. Australia's second largest state has become the first state to introduce the policy

C. No other countries but Australia decide to drink recycled water

D. The drought is the worst one in the droughts recorded in Australian history.

What can we learn from the last paragraph ?

A. Australians have never like drinking purified waste water

B. Australians should develop more water sources to live through the hard time

C. Australians can’t depend upon rainwater , which is not suitable for drinking .

D. Australian government has no ability to solve the problem of water shortage

The underlined phrase “adhered to” in Paragraph 9 probably means_________.

A. disliked    B. gone against    C. supported   D. doubted  

It can be inferred from what Premier Peter Beattie said that________.

A. he gives orders to drink purified waste water

B. It is painful for him to see his people drink recycled sewage

C. If the decision is made, people won’t survive the drought

D. It’s up to you to either make a life or death decision

Women who own cats are more likely to have mental health problems and kill themselves because they can be infected by a common parasite that can be caught from cat litter, a study has found.

Researchers found women infected with the Toxoplasma gondii (T. gondii) parasite(刚地弓形虫), which is spread through contact with cat waste or eating undercooked meat or unwashed vegetables, are at increased risk of attempting suicide.

The study involved more than 45,000 women in Denmark. About a third of the world’s population is infected with the parasite, which hides in cells in the brain and muscles, often without producing symptoms.

The infection, which is called toxoplasmosis(弓形虫病), has been linked to mental illness, such as schizophrenia(精神分裂症), and changes in behavior.

The study’s senior author Doctor Teodor Postolache, an associate professor of psychiatry(精神病学) at the University of Maryland School of Medicine in the United States, said, “We can’t say with certainty that T. gondii caused the women to try to kill themselves, but we did find a predictive association between the infection and suicide attempts later in life that deserves additional studies.”

Doctor Albert Reece, vice president of medical affairs at the University of Maryland, said, “T. gondii infection is a major public health problem around the world, and many people don’t realize they’re infected.

“Dr Postolache is a leading expert on suicide neuroimmunology(神经免疫学). Suicide is a critically important mental health issue. About one million people commit suicide and another 10 million attempt suicide worldwide each year. We hope that this type of research will one day help us find ways to save many lives that now end too early in suicide.”

Dr. Postolache’s research team at the University of Maryland was the first to report a connection between T. gondii and suicidal behavior in 2009. He is cooperating with researchers in Denmark, Germany and Sweden to confirm and investigate the way leading to this association.

The T. gondii parasite thrives in the intestines of cats, and it is spread through their waste. All warm-blooded animals can become infected through contact with it. Humans can become infected by changing their infected cats’ litter boxes, eating unwashed vegetables, drinking water from a polluted source, or by eating undercooked or raw meat.

Not washing kitchen knives after preparing raw meat before handling another food item also can lead to infection. Pregnant women can pass the parasite directly to their unborn babies and are advised not to change cat litter boxes to avoid possible infection.

Babies don’t produce antibodies to T. gondii for three months after they are born, so the antibodies present in their blood represented infection in the mothers. The scientists studied Danish health patients to determine if any of these women later attempted suicide, including cases of violent suicide attempts which may have involved guns, sharp instruments and jumping from high places.

The study found that women infected with T. gondii were one and a half times more likely to attempt suicide compared to those who were not infected, and the risk seemed to rise with increasing levels of the T. gondii antibodies.

Dr Postolache noted limitations to the study, such as the inability to determine the cause of the suicidal behavior.

The findings were published online in the Archives of General Psychiatry.
