[EX Q]: Article: The gray-haired lady can't wait to leave the building to search for her dad. Unless watched, she will walk in the streets in an effort to find her father, who died 30 years ago. Not all cases of Alzheimer's disease look like this, but Alzheimer's is a serious disease that is said to be the fourth or fifth leading cause of death for people over age 75. It is said that about three percent of the U.S. population over age 65 have Alzheimer's. In the early stages, people may exhibit short-term memory loss. Some may experience changes in personality, easy to be angry. As the disease progresses, patients might lose the ability to move and may be unable to speak or move at all. This progressive disease generally lasts 8 to 10 years before death occurs. While no one is certain what causes these changes in the brain's nerve fibers , their effect is certain. Alzheimer's destroys not only the patients, but also spouses , friends and families. What should you do if you notice progressive memory loss in yourself or a loved one? Have the person examined by a doctor who is a specialist in the treatment of Alzheimer's disease? Though many reasons other than Alzheimer's disease may cause memory loss, its early diagnosis and treatment may delay some of the most serious effects. What feeling will you likely experience if a loved one suffers from Alzheimer's disease? A person will often go through the various stages of sadness, shock, anger, and so on. If the spouse develops the disease, you may experience hurt and disappointment when he or she doesn't remember you are married. Life for the Alzheimer's patients and their loved ones will never be the same as the disease progresses, bringing a deep sorrow, loss and even anger towards God. No matter what feelings are present, facing them honestly will serve one better than burying them.

[EX Q]: Article: A jobless man applied for the position of "office boy" at Microsoft. The HR manager interviewed him and then watched him cleaning the floor as a test. "You are employed," he said. "Give me your e-mail address and I'll send you the application to fill in, as well as date when you may start. " The man replied, "But I don't have a computer, neither an e-mail. " "I'm sorry," said the HR manager. "If you don't have an e-mail, that means you do not exist. And who doesn't exist cannot have the job. " The man left with no hope at all. He didn't know what to do, with only ten dollars in his pocket. He then decided to go to the supermarket and buy 10kg tomatoes. He then sold the tomatoes from door to door. In less than two hours, he succeeded to double his capital. He repeated the operation three times, and returned home happily with 60 dollars. The man realized that he can survive in this way, and started to go every day earlier, and return late. Thus, his money doubled or _ every day. Shortly, he bought a cart, then a truck, and then he had his own fleet of delivery vehicles. Five years later, the man is one of the biggest food retailers in the US. He started to plan his family's future and decided to have a life insurance. He called an insurance broker and chose a protection plan. When the conversation was concluded the broker asked him his e-mail. The man replied, "I don't have an e-mail. " The broker answered curiously, "You don't have an e-mail, and yet have succeeded to build an empire. Can you imagine what you could have been if you had an e-mail?" The man thought for a while and replied, "Yes, I'd be an office boy at Microsoft!"
Question: Why can't the man have the job at Microsoft?
Options: (A) Because he was lazy. (B) Because he didn't pass the test. (C) Because he didn't have an e-mail. (D) Because he didn't have a computer.

[EX Q]: Article: Go to church, then have a big lunch, then go out to play while mum does the housework. That was a typical British Sunday in the 1960s. But things now could not be more different. Some British sociologists recently studied the typical British Sunday. They found that people get up later and do less housework than they did 40 years ago. They are far more likely to be out shopping or enjoying themselves than cooking Sunday lunch. Sunday mornings were busy 40 years ago. Most women caught up on their weekly housework and cooked a nice lunch. They seldom allowed themselves any "leisure" until afternoon, after the dishes were cleaned. Then there would be another rush to the table between 5:00 pm and 6:00 pm for tea. But now, Britons can have brunch at the restaurant. Fewer people bother to cook themselves. "You only have two free days a week. You don't want to have to waste one because there is nothing to do but watch boring TV," said Elizabeth Biggs, 25, a producer in London. "On Saturday you are recovering from the week," Biggs added. "Sundays are the last chance for the weekend -- you want to get as much as you can out of the day before you have to go back to work." In the past, British women usually did their shopping during the week, while the husband was at work. "Now men seem to do that as much as women," said Jonathan Gershuny, a professor who took part in the study. Men also do more housework now on Sundays. Back in the 1960s, men were far more likely to spend Sundays out of the house -- at the pub or playing football -- before lunch.
