单选题 Some time between digesting Christmas dinner and putting your head back down to work, spare a thought or two for the cranberry. It is, of course, a{{U}} (1) {{/U}}of Christmas: merry bright red, bittersweetly delicious with turkey and the very devil to get out of the tablecloth{{U}} (2) {{/U}}spilled.

Why make a cranberry taste like an orange? Mostly because it is a{{U}} (7) {{/U}}little fruit: FFPS have a shelf-life of two years. Better{{U}} (8) {{/U}}, they keep a chewy texture{{U}} (9) {{/U}}baked, unlike the fruits whose flavours they mimic, which turn to{{U}} (10) {{/U}}.

单选题The one accident situation where immediate action must be taken is when a person stops breathing. This might be the result of drowning, electrocution, suffocation, head injury caused by a fall, poisoning or a variety of other accidents. If someone has stopped breathing, however, there may be a simpler cause; the breathing passages may be blocked by food, vomit, saliva or even the tongue. Whatever the cause, it is imperative that breathing is restarted quickly, as otherwise brain damage may result. Act quickly: lay the casualty flat on his back, and pull back the head while holding the jaws clenched. This prevents the tongue from falling back into the throat and blocking the air passages. If any foreign matter like sand or vomit can be seen in the victim" s mouth or throat, scoop it out with the fingers. False teeth are a particular hazard and often fall back into the throat of an unconscious person. If breathing does not start immediately, you must begin artificial respiration right away, by breathing directly into the casualty" s lungs through the mouth or nose. . . As you exhale deeply through the casualty" s nose, it is necessary to hold their mouth firmly closed. If you are breathing into the mouth, however, pinch the nostrils to stop the escape of air. If the airways are not obstructed you will see the chest of the casualty" s lungs. Each time you blow, turn your head to check that there is this regular rise and fall of the chest. This must be continued until breathing starts spontaneously, or in any event for at least an hour. As soon as the casualty starts to respond you should see an improvement in his colour, usually after the first dozen or so inflations. When breathing starts, it will be weak and shallow, and will still need assisting. Time your breaths to coincide with those of the casualty, as his breathing gradually strengthens. When breathing has restarted and can continue without help, the casualty will still be unconscious. He should be turned into the "unconscious" position, preferably with the body slightly higher than the head, and watched carefully to make sure that breathing continues. Don" t rush to get him to hospital. It is more important to make sure that breathing is strong and will continue while the casualty is being moved.

单选题What makes teenagers moody and impulsive? The answer used to be raging hormones plus a dearth of(短缺) life experiences. But three years ago this simple equation was blown apart by evidence from brain scans of strange goings-on behind the teenage forehead. Till then, scientists had thought the brain's internal structure was fixed by the end of childhood. The new scans showed the brain's frontal cortex(皮层) thickening just before puberty(青春期), then slowly shrinking back to normal during the teenage years. Suddenly, the erratic huffiness(发怒) seemed to make sense: the teenage brain was a work in progress, a house in the process of being rewired. Now comes more evidence of neural turmoil. According to psychologists in California, the speed with which youngsters can read the emotional expressions on people's faces dips suddenly at around the age of 11 or 12 and takes years to get back on track. The latest study, like the brain scan research before it, is a welcome and necessary part of building up a picture of a typical teenage brain so that scientists can get a better handle on what might be happening in the mental illnesses that appear to be afflicting children and adolescents in ever greater numbers. But there are dangers. Scientists still have no idea how to interpret the subtle changes seen in adolescent brain scans. Yet in the wrong hands, these findings could be used to justify hothousing, impulse control training and other dubious attempts to get the most out of malleable teenage brain cells. The science could also spark a new wave of moralising based on a perceived need to protect teenagers' evolving brain connections from evil or toxic influences. Incredibly, some scientists have already suggested in the press that the brain scan evidence somehow proves that it is biologically bad for teenagers to play video games or lie on the couch watching MTV. A hundred years, ago one well-known "expert" urged teenage boys to drink six to eight glasses of hot water a day to flush impure thoughts from their bodies. Have we really learned so little?

单选题Will fatherhood make me happy? That is a question many men have found themselves asking, and the scientific evidence is equivocal. A lot of studies have linked parenthood—particularly fatherhood—with lower levels of marital satisfaction and higher rates of depression than are found among non-parents. To investigate the matter further, psychologist Sonja Lyubomirsky decided both to study the existing literature, and to conduct some experiments of her own. The results suggest parenthood in general, and fatherhood in particular, really are blessings, even though the parent in question might sometimes feel they are in disguise. Dr. Lyubomirsky"s first port of call was the World Values Survey. This is a project which gathers huge amounts of data about the lives of people all around the planet. For the purposes of her research, Dr. Lyubomirsky looked at the answers 6,906 Americans had given, in four different years, to four particular questions. These were: how many children the responder had; how satisfied he (or she) was with life; how happy he was; and how often he thought about the meaning and purpose of life. She found that parents had higher happiness, satisfaction and meaning-of-life scores than non-parents. The differences were not huge, but they were statistically significant. Moreover, a closer look showed that the differences in happiness and satisfaction were the result of men"s scores alone going up with parenthood. Those of women did not change. Armed with this result, Dr. Lyubomirsky conducted her own experiment. The problem with projects like the World Values Survey is that, because participants are asked to recall their feelings rather than stating what they are experiencing in the here and now, this might lead them into thinking more fondly in hindsight about their parenting duties. Dr. Lyubomirsky therefore gave pagers to 329 North American volunteers aged between 18 and 94, having first recorded, among other things, their sex, age, ethnicity, socioeconomic status, marital status and number of children. She told them they would be paged at random, five times a day. When they were so paged, they were asked to complete a brief response sheet about how they felt, then and there. She did not, however, tell them why she was asking these questions. The upshot was the same as her findings from the World Values Survey. Parents claimed more positive emotions and more meaning in their lives than non-parents, and a closer look revealed that it was lathers who most enjoyed these benefits. It looks, then, as if evolution has bolted into men a psychological mechanism to keep them in the family. At first sight, it is strange that women do not share this mechanism, but perhaps they do not need to. They know, after all, that the children are theirs, and that a man"s potential to father an indefinite number of offspring if he can find willing volunteers, might encourage him to stray from the bosom of his family. Enjoying fatherhood, by contrast, will help keep him in the porch.
