Article: When people who are nature lovers worldwide wish all humans to realize the importance of their natural surroundings, many Australians are turning caring for the environment into a way of life. Julie, an Australian housewife in Brisbane is one such example. Even though autumn is approaching Australia's Brisbane in April, one can still watch colorful blooming flowers in Julie's little garden, as she tells that in her community,"Each of us has a beautiful yard. The whole community, from children to elderly people, takes care of the environment as if they are taking care of their own garden." "Gardening is the most popular club in our community," she says. "A lot of retired people don't just regularly organize gardening lectures, but also personally visit families in the community to provide gardening training. So you can see that flowers continue to blossom in our gardens throughout the year." Talking about her people's sense of caring for the environment, Julie says when people in the community take along their dog, they always carry a garbage bag to deal with the dog's waste. "In our community, you will never experience the embarrassment of stepping on the dirty waste while you are walking on the grass," says Julie with a smile. "Taking care of the dog's waste can also help to develop children's sense of responsibility!" As to protecting water resources, the Australian government has made strict rules for families. Julie says, "We certainly would not use tap water to water the flowers!" She says almost every family in her community has a huge tank used to store rainwater, which is later used as the resource of all outdoor water use, including car washing and watering the garden. This year, they also asked people to connect the water tank with their toilets.

Options: (A) Families are taught how to take care of their gardens. (B) Gardening lessons are often given by professors. (C) The local government provides free gardening training. (D) There is enough rainwater to water the flowers regularly.

Article: A study of a million UK women, published today in The Lancet, has shown that happiness itself has no direct effect on mortality, and that the widespread but mistaken belief that unhappiness and stress directly cause ill health came from studies that had simply confused cause and effect. Life-threatening poor health can cause unhappiness, and for this reason unhappiness is associated with increased mortality. In addition, smokers tend to be unhappier than non-smokers. However, after taking account of previous ill health, smoking, and other lifestyle and socio-economic factors, the investigators found that unhappiness itself was no longer associated with increased mortality. The lead author, Dr Bette Liu, now at the University of New South Wales, Australia said: "Illness makes you unhappy, but unhappiness itself doesn't make you ill. We found no direct effect of unhappiness or stress on mortality, even in a ten-year study of a million women." As in other studies, unhappiness was associated with deprivation, smoking, lack of exercise, and not living with a partner. The strongest associations, however, were that the women who were already in poor health tended to say that they were unhappy, stressed, not in control, and not relaxed. The main analyses included 700 000 women, average age 59 years, and over the next 10 years these women were followed by electronic record linkage for mortality, during which time 30 000 of the women died. After allowing for any differences already present in health and lifestyle, the overall death rate among those who were unhappy was the same as the death rate among those who were generally happy. The study is so large that it rules out unhappiness being a direct cause of any material increase in overall mortality in women. This was true for overall mortality, for cancer mortality, and for heart disease mortality, and it was true for stress as well as for unhappiness.
Question: The word "mortality" in the passage means .
Options: (A) richness (B) relaxation (C) death (D) morality

Article: It's what people who don't know each other talk about on elevators. And not about the weather at all. Chatting about the weather with strangers is about emotional comfort (,). When someone says "Beautiful day today, isn't it?" as you settle into that narrow elevator space, or at the bus stop, or waiting in line at the supermarket, the conversation is about feelings. The person is speaking to feel more comfortable with you and offering you a chance to feel more comfortable with him or her. Being in close proximity with strangers creates interpersonal tension. We can't help it. Tension automatically seeks resolution. What will you do? Do you notice the person now only a short distance away, or pretend not to notice? Avoidance is one strategy: never make eye contact and act as if nobody is there, even when your feelings tell you. In a supermarket checkout line you might leaf through a magazine. On elevators, we often avoid others by looking up at the floor numbers. The other strategy is to break the tension by noticing the other person. It starts with eye contact. Then we have a choice: smile, nod, make a remark or strike up a conversation. If we choose to talk, the most non-controversial subject to talk about is the weather. A remark about the weather evokes agreement and feelings of sympathy. "What a nice day!" shares a tiny sliver of happiness. "I wonder if this rain will ever end." shares the bad feelings with each other. Both ends of the mini-conversation feel a tiny bit more connected by experiencing this emotion of liking or disliking the weather at the same moment.
