Raising a baby takes a lot of work, especially when that baby is a king penguin. Now, it looks like climate change will make life even harder for these birds.

Most king penguins live on the Crozet Archipelago, a group of islands in the Indian Ocean, about 1，000 miles north of Antarctica. After the penguin chicks are born in November，which is summer in the Southern Hemisphere，both parents spend 4 months collecting fish to feed their offspring (后代)．

When the fish move to deeper waters in March, the adults swim hundreds of miles south. There, near the Antarctic ice, they spend the winter eating seafood to add to their own energy stores. In October, the parents return to their babies and finish raising them.

Scientists from France have been studying king penguins for a decade. Starting in 1998，Yvon Le Maho and his colleagues put electronic ID tags under the skin of hundreds of penguins. These are the same types of tags you might put in your dog or cat so that you can track them if they're lost. The tags have allowed researchers to get everything about penguins, such as how long they live, whether they return from their winter trips, and if their babies manage to survive the winter.

To see whether water temperatures affect the penguins, Le Maho compared his data with temperature records. Ocean surface temperatures vary from year to year. And previous research had shown that fewer fish and other creatures grow when the water is warmer. Le Maho suspected that this drop would make it harder for adult penguins to survive the hard times ahead. Indeed, his results showed that fewer adults survived during winters when the water was especially warm.

King penguins can live for up to 30 years. And for now, the population still appears healthy. But a warming trend could spell big trouble for a bird that depends on cold and ice.

As any parent knows too well, sometimes a little white lie is the only way to make a naughty child quiet. Indeed, parents have shared the top white lies they’ve told their children. While some of them are amusing, others are somewhat cruel.

“Father Christmas is watching you,” “Carrots will make you see in the dark” and “Your pet has gone to live on a farm” are among the top white lies parents tell their children. The top 20 list of little lies that adults use shows that four in five parents have told their children something that isn’t true. The threat of Father Christmas is on the top, with 62 percent of parents employing St. Nick to keep their kids under control. The second on the list is: “We’ll see”, which any little one knows really means “no”.

The majority of British people say that they lie to their children to protect their innocence, to save them from being upset or to stop them behaving badly. The top white lie told to kids about their pets is “your pet has to live on a farm in the countryside”, which is employed after one dies or has gone missing. On average, parents think that children are ready to start learning about death at the age of seven and a half.

One 62-year-old recalled that when he was four, his cat ran away, because it kept having its tail pulled. It was 53 years later that it was revealed that the cat had actually been given away to stop it from scratching the furniture. One respondent (应答者) said that he still remembered that when he was young, he believed his father’s statement that the entire world used to be in black and white before colour photography came along.

Forty percent of parents say that they would definitely lie to their children to keep up their belief in Father Christmas, and over all say they’d certainly tell the truth about a pet dying. However, one in ten parents say they’ve replaced their children’s dead pet with a one looking the same to cheat their children into believing it was still alive and well, found the study by Blue Cross pet charity.

1.The threat of Father Christmas which is used to control children shows that .

A. some children fear and respect Father Christmas

B. Father Christmas is more important than parents

C. children should learn more about festivals

D. Father Christmas does live in the world

2.What can we conclude from Paragraph 4?

A. Children don’t understand why their parents tell white lies.

B. Parents’ white lies may do harm to their children.

C. Children don’t really mind their parents’ white lies.

D. Parents’ white lies may leave a deep impression on their children

3.What is the main idea of the last paragraph?

A. Parents’ different understandings of while lies.

B. Parents’ different attitudes to telling white lies.

C. Parents’ different worries about white lies.

D. Parents’ different white lies.

More people are dying from hepatitis(肝炎) than AIDS and tuberculosis, warns World Health Organization. The World Health Organization(WHO) has urged for action to wipe out hepatitis as ongoing illness worsens.

In its first global report on the infection, it said the number of people dying from treatable forms of the disease, often caused by alcohol and drug abuse, is rising. Viral hepatitis is believed to have killed 1.34 million people in 2015, and amount similar to that of tuberculosis.

But while those are both falling, hepatitis deaths are on the rise—increasing by 22 per cent since the turn of the century.

However, most of the 325 million people infected are completely unaware they have the virus and some lack life-saving medicines. As a result, millions of people are at risk of a slow progression to chronic liver disease, cancer and even death, the WHO warned, Margaret Chan, director general of the WHO, said: “Viral hepatitis is now a major public health challenge that requires an urgent response.”

The two most common forms, which are responsible for 96 per cent of deaths from the disease, are hepatitis B(HBV) and hepatitis C (HCV)

HBV can be passed on through unprotected sex and bodily fluids(液体). It requires life-long treatment with a drug commonly used to battle HIV. New infections of this type of the disease are falling, thanks to a vaccine given to 84 per cent of newborns across the world. However, just nine per cent of sufferers know they are infected, meaning many go under the radar and miss out on treatment.

HCV, usually spread through blood-to-blood contact with an infected person, can be cured relatively swiftly, but many patients across the world are unable to afford the medication. Around 1.75 million people were newly infected with HCV in 2015, bringing the global total to 71 million, figures suggests. But four fifths of those infected with this type of the disease are unaware they are suffering, the WHO warned.

Experts looking at the cases have identified unsafe healthcare procedure and injection drug use as the top causes. Gottfried Hirnschall, director of WHO’s Department of HIV and the Global Hepatitis Programme, said the WHO was working with governments, drugmakers and diagnostics companies to improve access.

He added: More countries are making hepatitis services available for people in need—a diagnostic test cost less than $1 (78p) and the cure for hepatitis C can be below $ 200 (￡156). But the data clearly highlight the urgency with which we must address the remaining gaps in testing and treatment.

Charles Gore, president of the World Hepatitis Alliance, said: “For the first time in the history of viral hepatitis, we have an understanding of the true impact of the disease.”

1.Who are likely to die from the treatable hepatitis?

A. Those taking medicines. B. Those suffering from cancer.

C. Those caring their illnesses. D. Those being heavy drinkers.

2.What can we learn about hepatitis B?

A. Patients need to take drugs for the rest of their lives.

B. People will not get the new infections due to a vaccine.

C. Patients can be cured effectively at a costly price.

D. People will get infected through blood accidentally.

3.According to the statistics in 2015, which of the following statements is TRUE?

A. Hepatitis C is responsible for 96 per cent of deaths.

B. Around 1.75 million people were newly infected with hepatitis.

C. Most of those infected with HCV are aware they are suffering.

D. Tuberculosis is believed to have killed more than 1 million people.

4.The main purpose of writing the passage is _____.

A. to call on the public to fight with hepatitis

B. to request the public to care about the hepatitis patients

C. to warn the public to learn of the danger of the disease

D. to persuade the public to take regular examinations yearly

In spite of many invitations, he would always________ to join the get-togethers on account of his health condition.

A. reject B. refuse

Smog in Europe and North America could be more than 25 times more deadly than the average air pollution found in Chinese cities, a new study suggests. In the largest ever study of its kind in the developing world, researchers tested the effects of air pollution on the health of people in 272 cities in China.

They found average annual exposure to fine particles, known as PM2.5, in those cities was more than five times higher than the level recommended by the World Health Organization (WHO), according to a paper in the American Journal of Respiratory and Critical Care Medicine.

However they also discovered that it was much less likely to increase the death rate than PM2.5 in Europe and North America.

The researchers, led by Dr Maigeng Zhou, of the Chinese Centre for Disease Control and Prevention, suggested this was because China is affected by large amounts of natural dust blown by the wind from arid areas, while most pollution in the West comes from industry.

They found that for every increase of 10 micrograms of air pollution in a cubic meter of air, the mortality rate increased by 0.22 percent, discounting deaths from accidents.

Professor Frank Kelly, an expert in environmental health at King’s College London, who was not involved in the study but has studied air pollution in China, told The Independent: “Those relative risks are considerably less than those seen in Europe and the US. For mortality(死亡率) in Europe we are working on a six percent increase per 10 micrograms.” That suggests air pollution in Europe is about 27 times more toxic than average air pollution in China.

However, Professor Kelly said cities like Beijing, Shanghai and Hong Kong were likely to suffer from Western-style air pollution. "The natural dust component there is not of the magnitude that it would dwarf the coal, biomass and fossil fuel signals,” he said, “That may be true in certain cities whose pollution is not dominated by local power generation or major traffic congestion.”

Natural dust particles can cause physical damage to the lungs and trigger an asthma attack. Particles of carbon produced when fossil fuels are burned can lead to similar problems but they are also coated with toxic heavy metals, chemicals and volatile organic compounds. These are able to pass from the lungs into the blood stream where it is thought they cause further damage to the body.

Areeba Hamid, an air pollution campaigner with environmental group Greenpeace, said: “Poisonous air causes damage to people’s health wherever in the world they live. We now know fumes from diesel(柴油机) vehicles are a lot more poisonous than car companies claimed and this is a big cause of air pollution in Europe and North America. These companies have a lot to answer for, but so far they’ve managed to avoid any real accountability.”

The study of cities in China found the average annual expose to PM2.5 was 56 micrograms per cubic meter, compared to the WHO guideline limit for safe air quality of 10 micrograms.

People who were older than 75, had less education or who lived in hotter places were more likely to die. It is thought people in warmer cities were more likely to spend time outside or leave their windows open, thereby breathing more polluted air, the researchers said. They also speculated that less well educated people might have poorer access to health care or experience poorer environmental health conditions.

1.Why PM2.5 in China is less deadly than that in Europe and North America?

A. China is free from any pollution about PM2.5.

B. Pollutants affecting China mainly come from arid areas.

C. Fewer people died from PM 2.5 in China than those in Europe and North America.

D. Europe and North America are polluted by natural dust.

2.What does the underlined part in Para 7 refer to?

A. The average mortality rate. B. The higher mortality rate.

C. The lower mortality rate. D. The normal mortality rate.

3.What’s the real cause of air pollution in Europe and North America according to Areeba Hamid?

A. Fumes from diesel vehicles are much more poisonous.

B. The environmental agencies can’t take on responsibilities.

C. The technology doesn’t meet the standards.

D. Car companies can’t evaluate the results.

4.The author’s purpose of writing the passage is to ________.

A. appeal to people to lay an emphasis on environmental protection

B. illustrate smog in Europe and North America is quite serious

C. demonstrate China is safest place in the world to live in

D. provide some good ways to address the smog
