Our bodies are wonderfully skillful at keeping balance．When the temperature jumps, we sweat to cool down．When our blood pressure falls, our hearts can do something．As it turns out, though, our natural state is always changing．Researchers are finding that everything from blood pressure to brain function changes regularly with the cycles of sun, moon and seasons．And their insights （洞察力） are getting new ways for keeping away such common killers as heart disease and cancer．Only one doctor in 20 has a good knowledge of the scientific use of time in medicine．But according to a new American Medical Association, three out of four are eager to change that．“The field is exploding,” says Michael Smolensky．“Doctors used to look at us like, What spaceship did you get off ? Now they're thirsty to know more．”

In medical school, most doctors learn that people with chronic  conditions should take their medicine regularly．“It’s a terrible way to treat disease,” says Dr Richard Martin．For example, asthmatics （气喘患者） are most likely to suffer during the night．Yet most patients try to keep a constant level of medicine in their blood day and night, whether by breathing in on an inhaler （吸入器） four times a day or taking a pill each morning and evening．In recent studies, researchers have found that a large mid afternoon dose of a bronchodilator （支气管扩张剂） can be as safe as several small doses, and better for preventing nighttime attacks．

If the night belongs to asthma, the dawn belongs to high blood pressure and heart disease．Heart attacks are twice as common at 9 a．m．as at 11 p．m．Part of the reason is that our blood pressure falls at night, then rises as we start to work for the day．“Doctors know that,” says Dr．Henry Black of Chicago's Medical Center, “but until now, we haven't been able to do anything about it．” Most blood - pressure drugs provide 18 to 20 hours of relief （减缓）．But because they’re taken in the morning, they're least effective when most needed．“You take your pill at 7 and it's working by 9,” says Dr．William White of the University of Connecticut Health Center “But by that time you've gone through the worst four hours of the day with no protection．” Bedtime medicine would prevent high blood pressure, but it would also push blood pressure to dangerously low levels during the night．

1.Researchers are finding that _________ ．

A．heart disease and cancer are the most common killers of human beings

B．only blood pressure and brain function are decided by cycles of sun, moon and seasons

C．the functions of human bodies have much to do with nature

D．any change in human bodies goes with changes in the surroundings

2.According to the author, it is best for asthmatics to take their medicine _________ ．

A．at certain time

B．each morning and evening

C．when the disease occurs

D．at midafternoon

3.Which of the following statements is NOT true?

A．Doctors know more about illnesses than before．

B．Doctors in the U．S．used to be thirsty to know more about the new medical field．

C．The researchers' insights are providing new methods to prevent common killers．

D．The correct use of time in medicine attracts more attention in medical circle in the U．S．A．

4.The suggested title for this passage might be _________．

A．Medicine Is Everything               B．Treatment Is Everything

C．Timing Is Everything                 D．Prevention Is Everything

Why must we pay taxes? The answer is that the government needs money for many things, for example to pay its soldiers, sailors and airmen, to build roads, bridges, offices, schools, etc and to buy goods from abroad; and only the people of the country can supply the money．One of the most important taxes is income-tax which a person pays according to the amount of his income-tax．Whether he is a businessman, a doctor, a lawyer, a shopkeeper, a miner, or anything else．This is called a “direct” tax, because it is paid in money direct to the government．

Another tax is paid on goods such as watches, jewellery, new clothes, tobacco, wine, etc, when they are brought into a country, such a tax is paid as part of the price of these goods if they are later sold in shops．We call it “indirect” tax, because it is paid indirectly through the shopkeeper．

People usually complain about having to pay taxes, but they forget that the money is spent on the things that they and their families need．We need policemen to catch thieves, to see that men obey the laws, to direct traffic, etc, and they must be paid what they earn; children need education and there must be schools and teachers; we want our streets to be kept clean, and the wages of men who do this kind of work have to be paid．Above all, the country must always be ready to defend itself against attacking enemies, and we cannot have an army without paying for it．

Taxes, therefore, cannot be avoided．We buy our own food and clothes and pay for our own amusements, but there are several things that the State finds the money for, and that are necessary for us if our society is to continue．So we have no real cause to complain when we are asked to supply money to be spent for the good of ourselves and for our fellow-citizens．

1.Indirect tax means _______．

A．tax that one pays direct to the government

B．tax that is not paid directly to the government

C．tax that is paid as an extra amount added to the price of certain goods

Both B and C

2.Which of the following is right?

A．Taxes are paid to the sellers．

B．Income-tax is an indirect tax．

C．The tax on new clothes is paid in money direct to the government．

Tax is amount of money that you have to pay to the government so that it can pay for public services．

3.People have no real reason to complain about having to pay taxes because _______．

A．some shopkeepers are very rich

B．they need money to buy goods from abroad

C．their children need education

the money is spent on the things that they and their families need

4.“Taxes cannot be avoided” means _______．

A．people have to pay taxes to the government

B．you do not have to pay tax on some goods

C．soldiers do not have to pay taxes

all goods have to be taxed
