Most people who travel long distances complain of jetlag(喷气式飞行时差反应). Jetlag makes business travelers less productive and more prone【C1】______ making mistakes. It is actually caused by【C2】______ of your "body clock"-a small cluster of brain cells that controls the timing of biological【C3】______ . The body clock is designed for a 【C4】______ rhythm of daylight and darkness, so that it is thrown out of balance when it【C5】______ daylight and darkness at the "wrong" times in a new time zone. The【C6】______ of jetlag often persist for days 【C7】______the internal body clock slowly adjusts to the new time zone.
Now a new anti-jet, lag system is【C8】______ that is based on proven【C9】______ pioneering scientific research. Dr. Martin Moore-Erie has【C10】______ a practical strategy to adjust the body clock much sooner to the new time zone【C11】______ controlled exposure to bright light. The time zone shift is easy to accomplish and eliminates 【C12】______ of the discomfort of jetlag.
A successful time zone shift depends on knowing the exact times to either【C13】______ or avoid bright light. Exposure to light at the wrong time can actually make jetlag worse. The proper schedule【C14】______ . light exposure depends a great deal on【C15】______ . ravel plans. Data on a specific flight itinerary(旅行路线) and the individual's sleep【C16】______ are used to produce a Trip Guide with【C17】______ on exactly when to be exposed to bright light.
When the Trip Guide calls【C18】______ bright light you should spend time outdoors if possible. If it is dark outside, or the her is bad,【C19】______ you are on an aeroplane, you can use a special light device to provide the necessary light【C20】______ for a range of activities such as reading, watching TV or working.

TO FOREIGNERS, few things seem as peculiarly British as the habit of sending young children away from home to school. At first glance, boarding schools are thriving, with almost 70,000 children within their walls .Independent education (both day and boarding) produces better-than-average academic results: they teach only 7% of English pupils but supply 38% of those gaining three or more A grades in the A-level exams takenen age 18.
Yet some boarding schools are struggling. While the demand for private schools has increased over the past 20 years, the number of children at boarding schools has dropped sharply -- from 112, 135 in 1985 to68, 255 in 2005. The decline leveled off four years ago, thanks, say some, to the popularity of the Harry Potter books.
One reason why boarding schools have lost some of their appeal is high fees -- the average is around Pounds 18,830 ($35,470) a year. Lurid stories of children who harm themselves or take drags, far from parental eyes, have not helped. Some schools are in trouble financially: three mergers have taken place this year; one school in Buckinghamshire will close in August; and another, in Sussex, was recently rescued by parents.
Yet Adrian Underwood, national director of the Boarding Schools' Association, describes the future as "rosy". His optimism stems partly from renewed political interest in taking children from foster care and children's homes and sending them to boarding schools instead. Only 6% of those in care in 2004 got five god grades in their GCSE exams (taken at about 16 years of age), compared with 53% of children overall. Boarding schools can offer small classes and good discipline, helping pupils to counter the low expectations that prevent them from achieving all they could.
A working party in the Department for Education and Skills has spent months looking at ways to expand the programme. Pilot projects are due to start in September 2007. Among the 80 or so schools that are interested are Wellington, an independent senior school in Somerset, and the Dragon School, a preparatory school in Oxford. John Walker, speaking for Britain's prep schools (which educate children from ages 7 to 13), says they could take pupils as young as five years old. Local authorities are less enthusiastic. Schools want full responsibility for the children they accept, while councils and social workers want to be able to check up on them. Some think that removing children from any version of parenting could have damaging long-term effects. Holidays are also problematic: the Fostering Network, which represents foster-carets, says that many foster parents are unwilling to have children only for the holidays.
For boarding schools, both those with an idealistic streak and the financially strapped, the appeal of increasing numbers is clear, as long as other parents don' t squawk. They have another reason to be keen. New laws will soon require charities to justify their tax breaks by proving that they benefit society at large. Independent schools, 80% of which have charitable status, reaped pounds 88m in tax rebates in 2004. Accepting a few needy children alight well safeguard that status.
In the opening paragraph, the author introduces his topic by ______.

Section B
Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice.
If you see a fish tail splash in a shallow stream, you'll know that a trout is feeding on underwater insects that cling to the rocky bottom. A V-shaped wave through the water could be a large fish chasing a smaller one. And a loud jump in a splashy circle may be a big hungry fish gobbling up a frog or a swimming mouse.
It's always a good idea to watch the water for a while before you begin fishing. If you can figure out what the fish are feeding on, offer it to them on your hook, and you'll catch more fish.
All you need for bait fishing is a line on a pole, a couple of hooks, and some split-shot sinkers. Most of you who fish use earthworms as bait, but in their natural diet, fish eat very few worms.
The next time you are fishing in a clear stream, turn over some rocks and you will find insects clinging to the undersides. These insects, called nymphs, are good fish bait. Put a nymph on a very small hook and squeeze a split-shot sinker on your line a foot above it. The weight will drift the bait along the bottom of the stream, where the fish normally look for nymphs.
While you are collecting nymphs, you might also find some caddis cases. These rectangular cases made of tiny pebbles or sticks, are constructed by caddis larvae. Safe in their cases, the larvae cling to the stream's rocky bottom but sometimes they lose their hold and are carded downstream by the current, and hungry trout gobble them up -- case and all. You can use a caddis case as bait, drifting it along the bottom as you would a nymph.
Fish also eat caterpillars, grasshoppers, and beetles that fall into or swim on the water. And some fish will eat anything they can fit into their mouths.
Whatever bait you choose, remember to make it appear natural to the fish. If your sandwich leaped off the plate and danced across the table, you would hesitate to eat it. The same is true of fish. They are very cautious of any food that doesn't look and act natural.
Always use a hook smaller than your bait, so the fish won't see it. If you want the bait to sink, squeeze a split-shot onto the line. If you want it to float, take off the sinker. Watch the water and see how different insects behave; they imitate them with your bait.
