Jane was running late. Jane, 25, had a lot to do at work, plus visitors on the way: her parents were coming in for Thanksgiving from her hometown. But as she hurried down the subway stairs, she started to feel uncomfortably warm. By the time she got to the platform, Jane felt weak and tired—maybe it hadn't been a good idea to give blood the night before, she thought. She rested herself against a post close to the tracks.

    Several yards away, Tom, 43, and his girlfriend, Jennifer, found a spot close to where the front of the train would stop. They were deep in discussion about a house they were thinking of buying.

    But when he heard the scream, followed by someone yelling, "Oh, my God, she fell in!" Tom didn't hesitate. He jumped down to the tracks and ran some 40 feet toward the body lying on the rails. "No! Not you!" his girlfriend screamed after him.

    She was right to be alarmed. By the time Tom reached Jane, he could feel the tracks shaking and see the light coming. The train was about 20 seconds from the station.

    It was hard to lift her. She was just out. But he managed to raise her the four feet to the platform so that bystanders could hold her by the grins and drag her away from the edge. That was where Jane briefly regained consciousness, felt herself being pulled along the ground, and saw someone else holding her purse.

    Jane thought she'd been robbed. A woman held her hand and a man gave his shirt to help stop the blood pouring from her head. And she tried to talk but she couldn't, and that was when she realized how much pain she was in.

    Police and fire officials soon arrived, and Tom told the story to an officer. Jennifer said her boyfriend was calm on their 40-minute train ride downtown-just as he had been seconds after the rescue, which made her think about her reaction at the time. "I saw the train coming and I was thinking he was going to die," she explained.

    One of the newest words on the coffee stage is “shade grown coffee”. Shade grown coffee isn't new. In fact, until only a few years ago, shade grown coffee represented the major coffee beans sold on the world coffee market. The coffee plant is a natural shade lover, growing best in the shade afforded by an overgrowing canopy (树冠) of rain forest plants. That canopy protects the coffee plant from sunlight that reduces its production and kills it.

    Shade grown coffee is, however, more expensive to grow, at least in the short run. Growing coffee in the shade means that coffee growers also have to spend time working on the protectors. It means that less land is left to produce coffee beans. The arrival of technically engineered coffee plants that grow well in the sun represented a major development in coffee industry. Because there was no need to grow shade trees to protect the coffee trees, farmers could use more and more land to grow coffee trees, increasing their productivity and leading to more money for the coffee plantations (种植园) and farmers.

    However, it was not a good idea to move away from shade grown coffee. The sheltering canopy provided more than just shade for the coffee trees. Those plants provided shelter for birds and other animals who feed on pests.

    They help to fix nitrogen in the soil, and nitrogen is a natural fertilizer which makes plants grow more successfully. The increase in land used to grow sun loving coffee trees also had an unexpected effect on the law of supply and demand. The increased production resulted in a huge amount of coffee beans coming to the market, which brought down prices.

Moreover, most experts agree that shade grown coffee is better in taste than coffee grown in full sun. Plants grown in shade take longer to develop. The slower growing time helps to improve the coffee's taste. You can buy a can of shade grown coffee to replace your usual sun coffee. One cup of coffee a day—it's a small price to pay for a better world.

    Researchers found that walking around with a forced smile and fake happiness simply leads to people feeling unhappier. So, putting a brave face on your sadness could be harmful. The research also found that women suffered more than men when pretending to be happy.

    Dr. Brent Scott, who led the study, said employers should take note because forcing workers to smile when dealing with the public can result in bad outcomes. He said, “Smiling for the sake of smiling can lead to emotional tiredness, and that's bad for the organization.” He also said the research showed customer-service workers who had “fake smiles” throughout the day didn't want to work, so their productivity dropped.

    The study is one of the first of its kind to examine emotional expressions over a period of time and compare the different effects on men and women. Dr. Scott's team examined the effects of “surface acting”, or fake smiling, compared to “deep acting”, or making people smile by thinking of pleasant memories.

    Dr. Scott said, “Women were harmed more by surface acting, meaning their moods worsened even more than men's. However, they were helped more by deep acting, which means their moods improved more by thinking of pleasant memories.”

    According to Dr. Scott women tend to suffer more when pretending to be happy because they are expected to be more emotionally expressive than men. Therefore, forcing a smile while feeling down is more likely to go against their normal behavior and cause more harmful feelings.

    Although deep acting can improve moods a little in the short term, Dr. Scott says it's not a long-term solution to feeling unhappy. There have been some suggestions that if you do this over a long period you start to feel unreal. You're trying to develop positive emotions, but at the end of the day you may not feel like yourself any more.

    When you cross deep water driving too fast, you risk splashing water up into the air box and having it get sucked into the internal engine, which is more common than you think. There are a few steps you should take to clear the water out before you try to start it:

    ⒈First, drain the fuel tank, fuel lines and the oil. While it's draining, put a fan on the wiring and dry it out. Remove and clean the carburetor (化油器).

    ⒉Take the plugs out of the engine and turn it over to force any water out. Water will come out with the oil. Add oil to the engine and turn it over again, without the plug in. Let it sit for a while, then observe the oil to tell if there's any water in it (it will look like a white milky substance if there is water mixed with the oil). If it's there, drain it again and start over until there is little or no white showing in the oil.

    ⒊Now re-install the spark plug, add gas, then try to start the engine. You should have a can of ether (乙醚) handy just in case it's stubborn, but don't use too much. If it starts, let it run for a few minutes without making it work faster.

    ⒋After it runs for several minutes, shut it off, drain the oil and change the filter(过滤网). Run it again for a few minutes then shut it off and checks again for milky colored oil. If you have none, you should be good to go.

    ⒌If you cannot start the engine, you may have already ruined it and you will probably need to seek a professional to repair it, or, more likely, you'll have to replace it.

    People have been wondering why elephants do not develop cancer even though they have lifespans (寿命) that are similar to humans, jiving for around 50 to 70 years.

    Now scientists believe they know why. A team at the University of Chicago, US has found that elephants carry a large number of genes that stop tumors (肿瘤) developing. To be precise, they found 20 copies of an anti-tumor gene called TP53 in elephants. Most other species, including humans, only carry one copy.

    According to the research, the extra copies of the gene improved the animal's sensitivity to DNA damage, which lets the cells quickly kill themselves when damaged before they can go on to form deadly tumors.

    "An increased risk of developing cancer has stood in the way of the evolution of large body sizes in many animals," the study author Dr Vincent Lynch told The Guardian. If every living cell has the same chance of becoming cancerous (癌变的), large creatures with a long lifespan like whales and elephants should have a greater risk of developing cancer than humans and mice. But across species, the risk of cancer does not show a connection with body mass.

    This phenomenon was found by Oxford University scientist Richard Peto in the 1970s and later named "Peto's paradox (悖论)”". Biologists believe it results from larger animals using protection that many smaller animals do not. In the elephant's case, the making of TP53 is nature's way of keeping this species alive.

    The study also found that when the same genes were brought to life in mice, they had the same cancer resistance as elephants. This means researchers could use the discovery to develop new treatments that can help stop cancers spreading or even developing in the first place.

    "Nature has already figured out how to prevent cancer," said Joshua Schiffman, a biologist at the School of Medicine, University of Utah, US. "It's up to us to learn how different animals deal with the problem so that we can use those strategies to prevent cancer in people."
