Q My husband and I would like to spend five or six days in the Maldives. Could you
suggest some low-priced hotels? We'll be there in November. Jan Davies, email.
A Prices in the Maldives are high. The cheaper hotels (and there aren't many) mightn't
be much to look at, with unpleasant rooms, iron roofs, old buildings, poor and rough
vegetation and basic facilities, but they get their atmosphere from cheerful customers
and an untidy, free island feel.
Angaga (South Ari Atoll, phone 0011 960 450510), Asdu Sun Island (North Male
Atoll, email info@asdu.com.mv) are both a bit like this.
You'll be there in the low season (May to November), when its' still warm, but
there's a greater likelihood of rain, so you should be able to get a double (standard )
room with full board (three meals a day) for $ 100 a night.
However, pricing structures for the hotels are enormously complex for standard,
superior and luxurious rooms.
Q My husband and I are from Australia. We are planning a four-week trip to London, Dublin and Paris in October and we are shocked by the cost of hotels. We have
searched the Internet and hotel books given to us by tourist authorities but we can't
find anything cheaper than $ 150 a night.
Joan Maloney, email.
A For Australians traveling Europe, especially its capital cities, is expensive. You may
have to increase your budget . However, if you can't afford these costs, then you
should consider staying in hotels where the cheapest twin rooms with shared bathroom
cost about$20 a person in Dublin and Paris and $35 in London. The minimum you
would pay for a double room in a central area is $50 a person in Dublin and Paris and
$70 in London. These prices are for shared bathroom facilities, though you will get a
wonderfully unhealthy cooked breakfast thrown in.
Not all hotels are equal, of course, and it's a good idea to consult a guidebook with
a good reputation.
1.The hotel Angaga in the Maldives_________.
A. attracts untidy people B. has some basic facilities
C. has the best landscape D. can be contacted by email
2.If you spend your holiday in the Maldives in February, _________
A. there is a greater likelihood of rain
B. standard, superior and luxurious rooms are all available
C. the weather will probably be better than that of the low season
D. a standard room with full board will cost less than $100 a night.
3.What is the advice for the couple planning to visit Europe in October?
A. They should stay in hotels in a central area
B. They could live in hotel rooms of lower standard
C. They should put up with the wonderfully unhealthy cooked breakfast.
D. They should buy a reliable guidebook instead of increasing the budget.

Reading may be fundamental, but how the brain gives meaning to letters on a page has been a mystery. Two new studies fill in some details on how the brains of efficient readers handle words. One of the studies, published in the April 30 Neuron, suggests that a visual-processing area of the brain recognizes common words as whole units. Another study, published online April 27 in PLOSONE, makes it known that the brain operates two fast parallel systems for reading, linking visual recognition of words to speech.
Maximilian Riesenhuber, a neuroscientist at Georgetown University in Washington, D.C., wanted to know whether the brain reads words letter by letter or recognizes words as whole objects. He and his colleagues showed sets of real words or nonsense(无意义的词语)words to volunteers undergoing fMRI scans. The words differed inonly one letter, such as “farm” and “form” or “soat” and “poat”, or were completely different, such as “farm” and “coat” or “poat” and “hime”. The researchers were particularly interested in what happens in the visual word form area, or VWFA, an area on the left side of the brain just behind the ear that is involved in recognizing words.
Riesenhuber and his colleagues found that neurons(神经元)in the VWFA respond strongly to changes in real words. Changing “farm” to “form”, for example, produced as great a change in activity as changing “farm” to” coat”, the team reports in Neuron. The area responded slowly to single-letter changes in made-up words.
The data suggests that readers grasp real words as whole objects, rather than focusing on letters or letter combinations. And as a reader’s exposure to a word increases, the brain comes to recognize the shape of the word. Meaning is passed on after recognition in the brain, Riesenhuber says.
The researchers don’t yet know how longer and less familiar words are recognized, or if the brain can be trained to recognize nonsense words as a unit.
1.Riesenhuber’s research probably focuses on whether the brain ______.
A. recognizes words as a unit or reads them letter by letter.
B. operates two fast parallel systems for reading
C. takes longer to read less familiar words or not
D. handles nonsense words as a unit
2.Riesenhuber and his colleagues carried out their research by ______.
A. giving pairs of real words totally different B. arranging the words in different order
C. showing pairs of different words D. making volunteers read some longer words
3.Riesenhuber’s research is significant in that it shows how the brain ______.
A. responds to familiar words B. relates meaning to letters
C. recognizes the form of a word D. reacts to made-up words

Exercise may hold the key to youth, according to a study published on Monday which showed people who keep fit are up to nine years biologically younger than those who do not. The findings are the first to show in humans how keeping fit affects the ageing process.
The study of 2,40twins found that a sedentary（久坐的）lifestyle raises the risk of a range of problems from heart disease to cancer and appears to play a key role in the ageing process.
It all appears to boil down to（归结为）the length of structures called telomeres（染色体终 端）---which protect the DNA on the chromosomes（染色体）,the researchers from King's College London wrote in the Archives of Internal Medicine.
Many studies have shown telomeres get shorter over time, suggesting the cells are ageing or dying. The study, which extracted （提取）a DNA sample from their volunteers, found people who exercised more each week had longer telomeres.
Exercise lowers the risk of a range of problems such as heart disease, diabetes and cancer, the researchers said. “It is not just walking around the block. It is really working up a sweat." said Tim Spector, a genetic epidemiologist who led the study, in a telephone interview.
The study found people who exercised energetically 3 hours each week had longer telomeres and they were 9 years biologically younger than people who did under 15 minutes.
Spector's team, who also adjusted for body weight, smoking, economic status and physical activity at work, also said moderate（适度的）exercise for 1-2 hours each week provided a four- year advantage.
Studying twins also provided a unique opportunity to judge the effects of exercise on people with the same or similar genetic make-up. the researchers said.
The reason why exercise has this effect is not clear but the researchers said they believe physical activity somehow defends against the natural process called oxidative stress （氧化应激反应）.which damages and kills cells.
1.What is the risk of sedentary lifestyle?
A.It can cause diseases.
B.It can make our cells alive.
C.It can lengthen telomeres.
D.It can keep us fit.
2.What do we know from the text?
A.Exercising can shorten the telomeres.
B.The less exercise, the longer telomeres.
C.Sitting often boils more chromosomes.
D.Telomeres affect human being's ageing.
3.What can cause ageing according to the last paragraph?
A.Cells with diseases. B.Oxidative stress.
C.Genetic structure. D.Physical activities.
4.What is the purpose of the text?
A.To introduce some exercise.
B.To show how to do research.
C.To encourage people to exercise.
D.To advise people to lose weight.
