Blood donation, also called blood banking, is a wonderful thing to do. It is an easy and direct way of contributing to social work and having a big effect on the community. It helps to save lives and helps those who are in need of blood due to bad condition or the heavy loss of blood during operations or in accidents.

You are able to give or donate blood every three or four month, and it is such a beautiful way of making a huge difference to someone’s life and you can always be proud of it after making a valuable contribution to society. Blood donation is not a big problem, but you need to keep a few points in mind.

Before donating blood, make sure that the ferrum(铁)level in you body is high enough and for that you should take a healthy diet. Do not go for blood donation on an empty stomach. You should follow the correct process so that everything goes well. After having a balanced diet you will feel strong and comfortable to donate blood. Afterwards, you will not feel faint or weak.

For required hemoglobin(血红蛋白)in your body, drink lots of juice and other drinks. Fruit juice, such as apple juice is very good for increasing the blood level in your body.

For a good blood flow in your body, drink at least 6-7 glasses of water every day. Completely avoid, a day before and after giving blood, taking alcohol, caffeine, etc. Do not smoke half an hour before giving blood.

When you are going for blood donation, be relaxed, which helps keep the right blood pressure. During the blood donation activity take a deep breath and try to calm yourself. Don’t take part in some other activities.

When you donate blood, you are making the effort to save someone’s life. Blood donation is a very simple and fast process, but you need to take care of yourself after donating blood. Proper care helps to reduce side effects. The following are a few tips that will help you out.

Take a rest for 15 minutes after completion of the donation. It helps you to feel relaxed and energetic.

Eat something and drink juice before leaving the blood donation center. Make sure that you have meals after donating blood. Smoking should be avoided for one hour after the process. Avoid some activities right away, for example, driving.

Finally, be proud of yourself because you have done a great thing in helping to save someone’s life. Blood donation is a very important activity.

Mothers can still offer comfort, even from a distance, a new study has found. The results show that simply hearing their mothers’ voice over the phone works just as well at calming the nerves of stressed children as a real-life pat on the shoulder.

The soothing(抚慰的)effect is most likely due to the release of the hormone(荷尔蒙), oxytocin(催生素), in the brain, the researchers say. This “love hormone” is known to quell stress and is likely to be involved in social connections, including those between a mother and a child.

Previous work has revealed that this hormone is released during physical contact with a mother. “But it’s clear from these results that a mother’s voice can have the same effect as a hug, even if she isn’t actually standing there,” said the researcher, Leslie Seltzer, a biological scientist.

Seltzer tested a group of 61 girls, aged 7 to 12, by having them make an unprepared speech and solve a series of maths problems in front of a group of strangers, sending their hearts racing and levels of cortisol—a hormone associated with stress—soaring.

Facing a challenge like that raises stress levels of a lot of people. Once stressed, a third of the girls were comforted in person by their mothers with hugs. A third of the girls watched an emotionally neutral 75-minute video. The rest were handed a telephone with their mothers on the line.

For the girls who interacted in person or over the phone with their mothers, the levels of the “love hormone” rose significantly, and the stress-marking hormone was washed away. This effect didn’t show up for participants who watched the video.

Seltzer is now testing the amount of oxytocin released with other communication methods—like text messaging—and hopes to see the research spread out from human subjects. “It’s not just us, of course. Lots of very social species have voices,” she said. “on the one hand, we are curious to see if this effect is unique to humans. On the other, we’re hoping researchers who study vocal communication will consider looking at oxytocin release in other animals and apply it to broader questions of social behavior and evolutionary biology.

1.Mothers’ voice over the phone can reduce children’s nerves according to the study, because           .

A.children can imagine their mothers’ hugs on the line

B.children enjoy their mothers’ voice and forget their worries

C.mothers are good at comforting their children, even on the phone

D.mothers’ voice can promote the release of the love hormone

2.The underlined word “quell” in the second paragraph probably means “         ”.

A.cause or bring

B.delay or direct

C.stop or reduce

D.develop or train

3. From the study, we know that                .

A.the level of cortisol determines how stressed a person is

B.the 61 girls were divided into two groups in the research

C.the recent study had the same results as the previous one

D.watching a video is the best way to reduce one’s stress

4.From the last paragraph, we can conclude that          .

A.text messaging has the same effect on oxytocin release as telephoning

B.the effect of a mother's voice on oxytocin in animals is still not known

C.the effect of communication on stress is unique to humans

D.the research has been applied to social behavior and evolutionary biology

 

It may not be news to parents of teenage girls, but researchers have confirmed that no one can stop their 16-year-old daughter from deciding how the family spends its money.

The willpower and determination of teenage girls give them a big say in how a family’s money is spent on everything from food and meals to mobile phones, and, of course, clothes. Teenage boys did not show up at all in the analysis, which was designed to find out the influence of young people on household spending.

The findings on the spending power of teenage girls were calculated from Office for National Statistics records of family spending during the 1980s and 1990s. Researchers examined how much money went on services and leisure goods in different kinds of homes. They checked spending on food, restaurant meals, alcohol, tobacco, services, heating, transport, clothes and sports in 2,745 British families.

They found that teenage girls in the UK typically played an active role in family decisions about the allocation(分配)of household resources. But older children— those over the age of 21 who are still living with their parents—appear to have no say in household decisions.

They also tried to calculate to what extent the bargaining power of a teenager affected family budgets. “Every parent knows that children, even at a very early age, have their own preferences with regard to consumption, researchers said. “But children are only interested in a limited range of goods—mainly sweets and toys—and parents are able to use punishment to reduce their children’s bargaining power or remove it.”  When they become teenagers, however, girls are much more independent and they are capable of earning their own money, which improves their bargaining power in family decisions.

The researchers could not explain why girls have more influence over spending while the evidence for boys is much less conclusive. However, this study could be of great significance to market research and how marketers target children.

1. From the passage we can learn that            .

A.teenage girls have more influence over family budgets than teenage boys

B.teenage boys don't want to decide on household spending

C.teenage boys have some influence over household

D.teenage girls have weaker willpower and determination than teenage boys

2.What does the underlined part “give them a big say” in the second paragraph mean?

A.Make them dare to say something.

B.Make them want to know.

C.Make them say something meaningful.

D.Make their influence stronger.

3.It appears that household decisions are NOT affected by        .

A.girls living with parents

B.girls over 21

C.girls over 12

D.girls living alone

4.How can parents reduce children’s bargaining power?

A.By persuading them

B.By offering them sweets or toys.

C.By threatening to punish them.

D.By allocating household resources.

 

Since ancient times, people have known about its ability to reduce pain and high body temperature. More than 2000 years ago, the Greek doctor Hippocrates advised his patients to chew on the bark and leaves of the willow.

    The tree contains a chemical called salicin(柳醇). From salicin, researchers in the 1800s discovered how to make salicylic acid(酸). And in 1897, a chemist named Felix Hoffmann at Friedrich Bayer and Company in Germany created acetyl salicylic acid. Later it became the active substance in a new medicine that Bayer called aspirin. The "a" came from acetyl. The "spir" came from the spirea plant, which also produces salicin. And the "in" Well, that is a common way to end medicine names.

In 1982, a British scientist shared the Nobel Prize in Medicine in part for discovering how aspirin works. Sir John Vane found that aspirin blocks the body from making natural substances called prostaglandins(前列腺素).Prostaglandins have several effects on the body. Some cause pain and the expansion, or swelling( 肿瘤; 膨胀), of damaged tissue. Others protect the lining of the stomach and small intestine. Prostaglandins also make the heart, kidneys and blood vessels (血管)work well. But there is a problem. Aspirin works against all prostaglandins, good and bad. Scientists learned how aspirin interferes with an enzyme(酶). One form of this enzyme makes the prostaglandin that causes pain and swelling. Another form of the enzyme creates a protective effect. So aspirin can reduce pain and swelling in damaged tissues. But it can also harm the inside of the stomach and small intestine(肠).

1.What sickness can the medicine from the willow deal with according to the passage?

A. Cold        B. Toothache         C. Cancer        D. Skin disease

2.What can we know about Prostaglandin according to the passage?

A. It results from pain.   

B. It prevents the lining of the stomach and small intestine.

C. It causes blood vessels to work wrongly.

D. It is sometimes good but sometimes bad.

3.What can we know about aspirin according to the passage?

A. Aspirin can treat almost diseases.

B. Aspirin can create the protective enzyme.

C. Aspirin can harm the inside of the stomach and small intestine.

D. Aspirin can protect the inside of the stomach and small intestine.

 

In nineteen ninety-nine, twelve percent of public elementary schools in the United States required students to wear uniforms. Just three years later, estimates were almost double that.

A study of six big-city Ohio public schools showed students who were required to wear uniforms had improved graduation, behavior and attendance rates. Academic performance was unchanged.

Some middle and high schools in Texas have also joined the movement. Yet studies find mixed results from requiring uniforms. And some schools have turned away from such policies.

Supporters believe dressing the same creates a better learning environment and safer schools. The school district in Long Beach, California, was the first in the country to require uniforms in all elementary and middle schools. The example helped build national interest in uniforms as a way to deal with school violence and improve learning.

Findings in Long Beach suggested that the policy resulted in fewer behavior problems and better attendance. But researcher Viktoria Stamison, who has looked at those findings, says they were based only on opinions about the effects of uniforms.

She says other steps taken at the same time to improve schools in Long Beach and statewide could have influenced the findings. The district increased punishments for misbehavior. And California passed a law to reduce class sizes.

In Florida, for example, researcher Sharon Pate found that uniforms seemed to improve behavior and reduce violence. In Texas, Eloise Hughes found fewer discipline problems among students required to wear uniforms, but no effect on attendance.

Sociologist David Brunsma has studied school uniform policies since nineteen ninety-eight. He collected the reports in the book. In his own study, he found that reading and mathematics performance dropped after a school in rural Pennsylvania required uniforms.

Political and community pressures may persuade schools to go to uniforms to improve learning. But David Brunsma and others believe there is not enough evidence of a direct relationship. In fact, he says requiring uniforms may even increase discipline problems.

52. What’s the main idea of this passage?

A. More and more students are required to wear uniforms in the US.

B. Wearing uniforms contributes to good academic performance.

C. Researchers in the US argue for school uniform policies.

D. Evidence for school uniform policies in the US is seen as weak.

53. Which was/were the first in the US to require uniforms in all elementary and middle schools?

A. Six big-city Ohio public schools.

B. The school district in Long Beach, California.

C. Some middle and high schools in Texas.

D. Some elementary and middle schools in Florida.

54. Which of the following researchers are NOT supporters of school uniform policies?

A. Viktoria Stamison and Sharon Pate.  

B. Sharon Pate and David Brunsma.

C. Eloise Hughes and Sharon Pate.  

D. Viktoria Stamison and David Brunsma.

55. The underlined word “misbehavior” in the sixth paragraph probably means ______.

A. serious crime            B. bad performance

C. absence for class       D. action against wearing uniforms

56. We can infer from the passage that ______.

A. more work is needed to get better information about uniform’s effect

B. the number of schools requiring uniforms in the US will decline sharply

C. wearing uniforms has little to do with behavior and learning

D. politicians and communities won’t vote for uniform policies
