Article: Not all think laughter is the best medicine, but it seems to help.So scientists carried on a new study of diabetes patients who were given a good dose of humor for a year to prove it. Researchers divide 20 high-risk diabetic patients into two groups.Both groups were given standard diabetes medicine.Group L viewed 30 minutes of humor of their choice, while Group C, the control group, did not.This went on for a year of treatments. By two months into the study, the patients in the laughter group had lower level of the hormones epinephrine , considered to cause stress, which is known to be deadly.After the 12 months, _ rises 26 percent in Group L but only 3 percent in Group C.In another measure, C-reactive proteins, a maker of heart disease, drop 66 percent in the laughter group but only 26 percent in the control group. "The best doctors believe that there is a physical good brought about by the positive emotion, happy laughter," said study leader Lee Berk of Loma Linda University.And other research has found that humor makes us more hopeful.Still, more study is needed, Berk said.The research by Berk found that humor can bring about similar changes in body chemistry, which was proved in the new study.The research result will be presented this month at the meeting in the US.Research at the University of Maryland School of Medicine shows that laughter causes the inner lining of blood vessels to expand, increasing blood flow in a way thought to be healthy. "Lifestyle choices have an important effect on health and these are choices which we and patients should pay attention to, rather than prevention and treatment," Berk said in a statement this week. Question: Why did the scientists carry on the new research? - To find out if laughter was good to health. - To discover the best medicine to cure diabetes. - Because the number of diabetic patients is the largest in the world. - Because diabetic patients need more laughter than other patients.
To find out if laughter was good to health.

Read the following article and select the best answer. Article: Do you think Great Britain and the United States are alike? Winston Churchill once joked that the people of Britain and the people of America are separated only by their language. Do you think that is true? The British and the Americans both speak English as the official language. However, each uses some different words.We Americans are similar to the British. After all , our country was once owned by Great Britain , so we have a lot in common. But there are many differences between us. Great Britain has a king or queen, and the leader of the government is the Prime Minister. The United States has no kings or queens. Our leader is the President. Both the British and Americans use pounds and ounces, oints, quarts, and gallons. Both use miles, yards,and feet. Our money is different,though. The British use pounds and pence. Americans use dollars and cents. Driving in a car is very different in England. They drive on the left side of the road. We drive on the right. What we call the hood of the car, the British call the "bonnet". British cars run on "petrol",which we call gasoline. In our everyday lives, we do many of the same things as the British. But we describe them differently. A young mother here might push a baby in a baby carriage. A British mom pushes a "pram". The British watch the "telly", while we watch TV. We like to eat French fries, but the British call them "chips". Millions of Americans drink coffee, but most British prefer tea. So we are different in many ways. But we stay friendly anyway. Question: We can learn from the passage that _ - both British and Americans drive cars on the left side of the road - English is an official language in Britain but not in the US - the writer comes from the US and is friendly to British - the US also has queens and kings like Great Britain
the writer comes from the US and is friendly to British

Read the following article and select the best answer. Article: An old man in a faded yellow shirt sat in a windowless room on a raised concrete form. The only source of heat came from somewhere beneath the plastic mattress and the rough blanket the blank-faced police woman had handed him after taking his thumb prints. He heard voices and metallic clang as the cell door swung open. At the front desk a tired looking policeman handed the old man back his belongings, his worn-out cap and the Seiko watch that had stopped working the day his beloved Evelyn left. The policeman dramatically held the blue plastic bag at an arm's length to the old man who took it and made sure its contents were undamaged: the goat meat, palm oil, leaves and spices. He ignored the confused expression on the officer's face and signed the document declaring he had been returned the possessions they had taken off him the night before. No one spoke to him as he walked slowly towards the exit. "Mr. Easy-nwa?" He stopped and prayed to the God who now took care of Evelyn to please take him far away from this unhappy place of expressionless faces, clipped accents and people who did not even attempt to pronounce his name right. "Ezenwa," He said and looked at a woman with tangerine lips, her name tag said Jessica Harlow, Social Services. "A bit far from home,,,she said as she drove fast and with confidence the way Evelyn used to. He wondered if she meant the 50 miles from Liverpool or the 50,000 miles from Enugu,a city in Nigeria.

"Got here in the end",said she seriously, "Really Mr. Easy-nwa, if you keep getting lost, we will have to consider moving you into a home". "No need, I was not lost,,,he answered.
