How do you get a man to do his share of the housework? If you are like most women, you've faced this question the hard way. A man will enjoy a clean, orderly house, but he usually won't make the effort to clean or organise it. This doesn't mean that a woman has to do all the housework:; she may have to manage many of the household duties, and request her partner's participation . A woman can often say that men and women should take equal responsibility for housework. Very few men are raised to be fully responsible for housework, and many men look on housework as women's work. On the other hand, most men will readily work around the yard, make repairs and complete projects on weekends or evenings, and it's important that you give your man appreciation for those things, too. Most men will take on a little additional housework around the house if asked politely. They are even more likely to do housework if they can choose what they want to do, and do it without being monitored. Here's the key: men want to feel that they are doing housework either because they want to do a task, or because they simply want to please their women. Men are much less likely to take on household tasks they consider uninteresting and unimportant. In other words, men are likely to do a household task just for the good of the house. The passage is mainly about how to _ . A) get men to take on some housework B) get men to serve their families C) praise men' housework D) make men do all the housework

(Question)
A previously unknown kind of human group disappeared from the world so completely that it has left behind the merest piece of evidence that it ever existed -- a single bone from the little finger of a child, buried in a cave in the Altai Mountains of southern Siberia. Researchers removed DNA from the bone and reported that it differed obviously from that of both modern humans and of Neanderthals , living in Europe until the arrival of modern humans on the continent some 44,000 years ago. The child carrying the DNA line was probably 5 to 7 years old, but it is not yet known if it was a boy or a girl. The finger bone was unearthed in 2008 from a place known as the Denisova cave. Researchers are careful not to call the Denisova child a new human species, though it may prove to be so, because the evidence is initial. But the genetic material removed from the bone, found in a layer laid down on the cave floor between 48,000 and 30,000 years ago, belonged to a distinct human line that traveled out of Africa at a different time from the two known ancient human species. Homo erectus , found in East Asia, left Africa two million years ago, and the ancestor of Neanderthals moved away some 500,000 years ago. The numbers of differences found in the child's DNA indicate that its ancestors left Africa about one million years ago. The region was inhabited by both Neanderthals and modern humans at that time. Counting the new human line, three human species may have lived together. The standard view has long been that there were three human resettlements out of Africa -- those of Homo erectus; of the ancestor of Neanderthals; and finally, some 50,000 years ago, of modern humans. But in 2004, archaeologists reported that they had found the bones of small humans who lived on the Indonesian island of Flores until 13,000 years ago, causing a serious problem to this view. The new line is the second such challenge. If the nuclear DNA of the Denisova child should differ as much as its mitochondrial DNA... According to the passage, _ . A) modern humans arrived in Europe before Neanderthals B) modern humans arrived in Europe about 44,000 years ago C) Neanderthals arrived in Europe about 44, 000 years ago D) Neanderthals arrived in Europe soon after modern humans did

Ques: As skies are filled with millions of migrating birds, European scientists say the seasonal wonder appears to be strange: The fatter the bird, tile better it flies. The results of their study led to a theory opposite to a central one of aerodynamics , which says that the power needed to fly increases with weight. For birds, obviously, the cost of flying with heavy fat is much smaller than we used to think. Researchers found that red knot wading birds double their normal body weight of 100 grams before making their twice-a-year nonstop flight between the British Isles and the Russian Arctic. Distance: 5,000 kilometers. Another study in the magazine Nature measured the advantage of flying in an aerodynamic group which allows birds to save energy by flying smoothly and quietly in the lead bird' s air stream. Flying in groups, their heart rates were 14.5 percent lower than flying alone, according to Henri, a French scientist. The findings help explain how birds complete difficult migrations. Researchers had thought that thinner, stronger birds would have the best chance to survive. The first study suggests that building up fat to be burnt as fuel during the migration is worth more than the energy it takes to carry the additional weight. In the study, researchers said their team studied the birds flown at different body weights during 28 simulated flights. They forced a small amount of special water into the birds' bodies so that they could measure the amount of energy burnt during the flight. A _ red knot wading bird has a better chance to survive during its migrating flight. A) stronger B) weaker C) thinner D) fatter
Ans: D
Question: WASHINGTON--Considering the serious warnings lately about Internet viruses, users may be encouraged to unplug their machines just to keep them safe. In reality, common sense and a few basic tips can keep Internet surfers secure. Antivirus software is a must, and it should be updated at least once a week to recognize newly released viruses. People with broadband Internet connections should also have a firewall. These protect the computer from attacks by hackers. Then it is time to think about computer habits. Unlike old viruses, which spread only through shared diskettes, the Internet brings viruses straight to the email-box. If email with attachment comes from an unknown sender, or unexpectedly from a known sender, it should not be opened. On receipt of an unexpected attachment from a friend, experts suggest a telephone call to make sure of the mail's source before opening. Why should antivirus software be updated at least once a week? Because _ . A) the newly published antivirus software is more expensive B) the previous antivirus software cannot work longer than a week C) the inventors of viruses have suggested this idea D) computer viruses are always developing
