单选题Children who 1 unsupervised time in nature grow into more confident adults—adults who feel 2 in the world. As children play, they make no distinction between the natural world and themselves; they have an innate sense of themselves as belonging to and part of Nature. Children naturally connect and commune with animals as their "friends." This is why they are 3 to animal toys and cartoon figures. 4 there are frightening and dangerous animals in the world, this is knowledge that children acquire later—and is a 5 of the basic feeling of trust and safety they have with their animal companions. Too often in modern culture, "growing up" means becoming increasingly 6 from Nature and from our natural selves. A key part of saving our planet is changing our 7 with it, befriending it, feeling at home in the natural world. Since most of us live in cities these days, it is easy to 8 that a connection with nature is not possible, since nature is "out there" somewhere—in a national park or wilderness area. But nature is as 9 as our own animal bodies 10 breathe in rhythm with all of the living world. Even in the city we are surrounded with the wild nature of this planet. The Falconer of Central Park is a fascinating book that describes the myriad species of birds that touch down in Central Park in New York City as they annually 11 with the changing seasons.

单选题Which can be inferred form the passage about Wikipedia?

单选题Except at night, they hardly ever have time together. He often sits alone in the house waiting for Julie-Julie to come home. It would be nice to have kids to play with when one comes home from work. But, Oh, the house is too small, Kappy-Pappy dear. We need to save and move to a bigger place before we can start a family. Kapsak never understands that. What does a big house have to do with having children? When he and Eka Udo had children, did they have a big house? But they died, didn't they? And the doctor later said something about cramped living conditions making it easy for malaria to virtually wipe out his family. So maybe Julie-Julie has a point. All his children had died because of being cooped up in one room. All except Udo. Udo Kapsak would not ordinarily admit it but the truth is he misses the boy so much. Udo's full-faced smile. His quirky-chirpy ways. His innocent probing manner. Oh Udo! He'll be approaching five now. Five! A big baby! Sighing noisily, Kapsak tries to put thoughts of his son out of his mind. He has not seen the boy in over three years. And maybe he has gone the way his brother and sisters went. No. Not likely. Awadamoto would have told him. Awadamoto. It's been a long time since Kapsak saw him. Throwing on a shirt, Kapsak hurries off to the taxi rank in the business district. "Kapsak, Kapsak!" Awadamoto cheers as his childhood friend approaches. "Awadamoto! You have abandoned me!" "Use that word lightly, Kapsak. You know who has done the most abandoning between me and you." "But Awad, we live here in town together." "Blame that wife of yours. I did not go to school and I don't like going near people who make me remember that all the time." Kapsak has it in mind to say something good about his wife, but something else jumps to his mouth. "Come Awad, what is Gestapo?" "Gestapo?" "No, Gestapo." "Man, I don't know. Where did you hear it?" "Eh, I heard it somewhere. How is the village?" "Exactly as you left it." "And... " "Eka Udo?" "Yes. How is she?" "How does it concern you? Anyway, I heard some big chief from her mother's village has taken her for his third wife." "What of my son? Is it well with him?" "You would have known if you had bothered to go and check on him. Look, it's my turn. "Bawling out to passengers to climb into his ramshackle taxi, Awadamoto ambles off. It is pouring heavily when Julie-Julie returns. Outside, it is rain. Inside, it is confusion. Kapsak is at first happy to see her back safely. Then his happiness turns to anger as she carries on about what an exciting time she had. Finally his anger succumbs to her gentle caresses and passion rules their world. Julie-Julie shoots out at first light. "I've got to see someone urgently, Kappy-Pappy. "Kappy-Pappy, that is my name now, Kapsak laughs to himself as he shuffles off to the construction site where he manages to earn a few bucks. On his way into the main yard, he ducks out of the way of a fast-moving four-wheel drive vehicle driven by an expatriate. Cursing lightly, he looks back to see the driver locked in a passionate kiss with a woman with luxuriant hair. "No wonder he nearly killed me!" Kapsak spits out. "Early morning and he's already..." His mouth remains open but the words dry up. like the water taps of the city. The woman with the expatriate turns momentarily, perhaps to pick up something from the backseat. In that instant, Kapsak sees clearly the woman for whom he had left his first wife and forsaken his family and people. But he does not see the earthmover in front of him. Neither does he hear its powerful horns. And the driver of the earthmover does not see Kapsak. By the time someone notices the crushed figure lying by the roadside, a blackening pool of blood has begun to seep into the earth.

单选题What impact can mobile phones have on their users' health? Many people worry about the supposed ill effects caused by radiation from handsets and base stations, despite the lack of credible evidence of any harm. But evidence for the beneficial effects of mobile phones on health is rather more abundant. Indeed, a systematic review carried out by Rifat Atun and his colleagues at Imperial College, London, rounds up 150 examples of the use of text-messaging in the delivery of health care. These uses fall into three categories: efficiency gains; public-health gains; and direct benefits to patients by incorporating text-messaging into treatment regimes. The study, funded by Vodafone, the world's largest mobile operator, was published this week. Using texting to boost efficiency is not rocket science, but big savings can be achieved. Several trials carried out in England have found that the use of tenet-messaging reminders reduces the number of missed appointments with family doctors by 26—39%, for example, and the number of missed hospital appoint ments by 33—50%. If such schemes were rolled out nationally, this would translate into annual savings of￡256m—364m. Text messages are also being used to remind patients about blood tests, clinics, scans and dental appointments. Similar schemes in America, Norway and Sweden have had equally satisfying results though the use of text-message reminders in the Netherlands, where non-attendance rates are low, at 40%, had no effect other than to annoy patients. Text messages can also be a good way to disseminate public-health information, particularly to groups who are hard to reach by other means, such as teenagers, or in developing countries where other means of communication are unavailable. Text messages have been used in India to inform people about the World Health Organisation's strategy to control tuberculosis, for example, and in Kenya, Nigeria and Mall to provide information about HIV and malaria. In Iraq, text messages were used to support a campaign to vaccinate nearly 5m children against polio. Finally, there are the uses of text-messaging as part of a treatment regime. These involve sending re- minders to patients to take their medicine at the right time, or to encourage compliance with exercise regimes or efforts to stop smoking. The evidence for the effectiveness of such schemes is generally anecdotal, however, notes Dr. Rifat. More quantitative research is needed—which is why his team also published three papers this week looking at the use of mobile phones in health care in more detail. One of these papers, written in conjunction with Victoria Franklin and Stephen Greene of the University of Dundee, in Scotland, reports the results of a trial in which diabetic teenagers' treatment was backed up with text messaging. Diabetes needs constant management, and requires patients to take an active role in their treatment by measuring blood-sugar levels and administering insulin injections. The most effective form of therapy is an intensive regime in which patients adjust the dose of insulin depending on what they eat. This is more onerous for the patient, but allows for a greater dietary variety. Previous studies have shown that intensive treatment is effective only with close supervision by doctors. Dr. Franklin and her colleagues devised a system called Sweet Talk, which sends patients personalised text messages reminding them of the treatment goals they have set themselves, and allowing them to send questions to doctors. The Sweet Talk system was tested over a period of 18 months with teenage patients receiving both conventional and intensive diabetes treatment. A control group received conventional treatment and no text messages. The researchers found that the use of text-messaging significantly increased "self-efficacy" (the effectiveness of treatment, measured by questionnaire). More importantly, among patients receiving intensive therapy, the level of haemoglobin HbAlc--an indicator of blood-glucose and hence of glycaemic control--was 14% lower than for those in the control group. Since even a 10% decline in HbAlc level is associated with a reduction in complications such as eye and kidney problems, this is an impressive result. It suggests that texting can cheaply and effectively support intensive therapy among teenagers, who often demonstrate poor compliance. Despite such promising results, Dr. Rifat notes, many of the medical uses of text-messaging have not yet been subjected to clinical trials, because they are so new. And eyen where the benefits are proven, the technology has not been systematically deployed on a large scale. But when it comes to improving outcomes and reducing costs, text messages would seem to be just what the doctor ordered.
