Housework is a frequent source of disputes (争论) between lazy husbands and their hard-working wives, but women have been warned not to expect men to pull their weight any time soon.

    A study from Oxford University has found that men are unlikely to be doing an equal share of housework before 2050. Mothers, the researchers warned, will continue to shoulder the burden of childcare and housework for the next four decades, largely because housework such as cleaning and cooking is still regarded as “women's work”.

    The gap between the amount of time men and women spend on housework has narrowed slowly over the past 40 years. But it will take another four decades before true housework equality (平等) is achieved, the study concluded.

    The research found that in the Nordic countries, the burden of housework is shared more equally between men and women. In the UK, women spend an average of four hours and forty minutes each day on housework, compared with two hours and twenty-eight minutes for men. This is an improvement from the 1960s, when British women typically spent six hours a day on housework, while men spent just 90 minutes every day.

    But progress towards housework equality appears to be slowing in some countries. Dr Oriel Sullivan, a research reader from Oxford's Department of Sociology, said, “we've looked at what is affecting the equality in the home, and we have found that certain tasks seem to be given according to whether they are viewed as ‘men's work' or ‘women's work'.”

    Dr Sullivan said cultural attitudes taught at school may be responsible for the views of housework. “At school it is much easier for a girl to be a tomboy, but it is much more difficult for a boy to enjoy baking and dancing,” she said.

    After entering high school, you must wonder how to study well. Here are some good skills for you.

Go to class.

    If you want to do well at school, going to class is the first step in studying well. If you miss classes, you will miss what the teacher thinks is important; as a result, you'll miss what is the most likely to end up on the test.{#blank#}1{#/blank#}

Take good notes.

    Try not to write down everything.{#blank#}2{#/blank#}Write down unfamiliar terms. After class, review your notes as soon as possible. You can fill in details that you missed and review the material while it is still fresh on your mind.

{#blank#}3{#/blank#}

    If you are struggling in class, talk to your teacher. He or she may be able to give you more help or tutor you before or after class. Most teachers have little sympathy(同情) for students who just become worried about failing during the last few weeks of the grading period.

Take part in class discussions.

    In order to learn more in class, it is helpful to take part i n class discussions. Asking questions and having eye contact with your teachers and classmates can increase your participation(参与) and your focus during the class discussion.{#blank#}4{#/blank#} This helps you make your point clear in class.

Form study groups.

    {#blank#}5{#/blank#}Make sure that everyone is familiar with the material because you do not want to spend time re-teaching material to people who do not understand it. Be careful! Sometimes group sessions can become chatting sessions.

A. Don't be late for your class.

B. Talk to your teacher if you need help.

C. You should write down all the new terms.

D. So if you want to study well, go to every class.

E. Get students together who want to do well in class.

F. All you need is to put the main points in your own words.

G. If the material is difficult, you'd better read it before class.

Ways to Make People Like You

    ⒈Remember a person's name.

    It is said that the sweetest sound to a person's ears is their own name. "The average person is more interested in their own name than in all the other names in the world put together." People love their names so much that they will often donate large amounts of money just to have a building named after themselves. {#blank#}1{#/blank#}

    ⒉Be a good listener.

    Encourage others to talk about themselves. The easiest way to become a good conversationalist is to become a good listener. To be a good listener, we must actually care about what people have to say. {#blank#}2{#/blank#} They just want someone who will listen to them.

    ⒊Talk in terms of the other person's interest.

    {#blank#}3{#/blank#} If we talk to people about what they are interested in, they will feel valued and value us in return.

    ⒋{#blank#}4{#/blank#}

    "You can make more friends in two months by being interested in them than in two years by making them interested in you." The only way to make quality, lasting friendships is to learn to be genuinely interested in them and their interests.

    ⒌Make the other person feel important - and do it sincerely.

    {#blank#}5{#/blank#} We love to feel important and so does everyone else. People will talk to us for hours if we allow them to talk about themselves. If we can make people feel important in a sincere and appreciative way, then we will win all the friends we could ever dream of.

A. Become genuinely interested in other people.

B. We should think of questions in the shoes of other people.

C. Many times people don't want an entertaining conversation partner.

D. We should offer as much time as we can to other people who talk to us.

E. The golden rule is to treat other people as we would like to be treated.

F. The royal road to a person's heart is to talk about the things he or she treasures most.

G. We can make people feel extremely valued and important by remembering their name.

    The first newspapers were written by hand and put up on walls in public places. The earliest daily newspaper was started in Rome in 59 BC. In the 700's the world's first printed newspaper was published. Europe didn't have a regularly published newspaper until 1609, when one was started in Germany.

    The first regularly published newspaper in the English language was printed in Amsterdam in 1620. In 1621, an English newspaper was started in London and was published once a week. The first daily English newspaper was The Daily Courant (《每日新闻》). It came out in March, 1702.

    In 1690, Benjamin Harris printed the first American newspaper in Boston. But not long after it was first published, the government stopped the paper. In 1704, John Campbell started The Boston Newsletter (《波士顿新闻通讯》), the first newspaper published in the American colonies. By 1760, the colonies had more than thirty daily newspapers. There are now about 1,800 daily papers in the United States.

    Today, as a group, English language newspapers have the largest circulation (发行量) in the world. But the largest circulation for a newspaper is that of the Japanese newspaper Asahi Dhimbun (《朝日新闻》). It sells more than 11 million copies every day.

    Did you ever have to say "no" to somebody? Such as a classmate who asks to go to lunch with you? New research suggests that, at least socially, a rejection (拒绝) should not include an apology. In other words, saying you are sorry does not make the person being rejected feel any better. In fact, it might make the rejected person feel worse. That is surprising. Many people consider it to be good manners to say they are sorry when they turn down a request.

    Gili Freedman is doing some related research at Dartmouth College. For her research, she asked over 1,000 people to respond to different examples of social rejection. In one example, the researchers asked people for their reaction (反应）after a person named Taylor asked to join a co-worker who went out to lunch every Friday. And Taylor was told "no". But in some cases, the person rejecting Taylor offered an apology. In other cases, the people doing the rejection did not say they were sorry. People were asked how they would feel if they were being turned down, just as Taylor was. Most said they would be more hurt by a rejection with an apology than a rejection without an apology.

    Freedman said the reason is that apologies make people feel like they need to say that the rejection was okay— even when they felt like it was not okay. Rejection without an apology lets them express their feelings of disappointment, hurt or anger more easily. Freedman also said that an apology often makes the person doing the rejection feel better—even as it makes the person being rejected feel worse.

    Her research deals only with social communication. A business situation might be very different. "If a manager rejects a job interviewee or a boss must tell an employee that he or she is being fired from a job," Freedman said, "reactions to apologies may be different."

    Sweet potato plants don't have spines or poisons to defend themselves. But some have evolved a clever way to let hungry herbivores (食草动物) know they aren't an all-you-can-eat buffet, a new study finds. When one leaf injured, it produces a chemical that warms the rest of the plant and its neighbors to make themselves inedible (不宜食用的)to bugs. Sweet potato breeders could potentially engineer plants to produce the chemical as an all-natural pest defense.

    Plant ecologists led by Axel Mithofer of the Max Planck Institute for Chemical Ecology in Jena, Germany, started to look into sweet potato (Ipomoea batatas) defenses after they noticed something interesting about two varieties of the plant grown in Taiwan: The yellow-skinned, yellow-fleshed Tainong 57 is generally herbivore-resistant, but its darker orange cousin, Tainong 66, is plagued (造成麻烦) by insect pests.

    To find out why, the team offered up Tainong 57 and 66 plants to hungry African cotton leafworm caterpillars (毛虫).Both plants released at least 40 airborne compounds as the caterpillars snacked on their leaves. But Tainong 57 produced a lot more of a chemical called DMNT, which has a very distinct smell, the team details this month in Scientific Reports. ("The smell is not nice," Mithofer says. "You wouldn't want it as a perfume.")

    DMNT isn't a new compound; researchers have isolated (分离出) the smelly chemical from other plants such as corn and cabbage, and it is known to induce defense responses in some species.

    To determine whether this was happening in sweet potatoes, scientists set up two experiments. First, they put two plants next to each other and wounded one so it produced DMNT. Then, they exposed healthy Tainong 57 plants to DMNT they had synthesized (合成).In both cases, the DMNT caused the exposed plants to produce more of a protein called sporamin in their leaves. (Tainong 66 did not have the same reaction.) When the caterpillar's snack on sporamin, "they immediately stop eating because they don't feel well," Mithofer says.

    Sporamin is the main protein in sweet potato tubers (块茎),and is indigestible raw, which is why sweet potatoes must be cooked for humans to enjoy them. "If the caterpillars could cook it, they could eat it," Mithofer says. Theoretically, he says, sweet potato breeders could use genetic engineering to make different varieties of sweet potato produce as much DMNT as Tainong 57, and display the same defense responses.

    Still, the research isn't ready for prime time, cautions plant ecologist Martin Heil. DMNT might work in the lab, but in the field, airborne chemicals can be "blown away in seconds," says Heil, who studies plant-insect interactions at the National Polytechnic Institute in Irapuato, Mexico.

    Mithofer himself has no plans now to create genetically engineered sweet potato plants, because they would not be a viable (能活下去的) crop in Europe, where genetically modified crops are outlawed. So for now, Tainong 66 will have to put up with being a caterpillar salad bar.
