Single-sex schools are better than mixed schools Message 1 — posted by Jane,Amsterdam
I think mixed-sex schools are the only way for children to leam,because it's natural. In higher education and their working life,they will be mixed so it makes sense for them to be mixed at school. School should reflect the real world.
Message 2 — posted by Hans,Germany
My reaction to this is very clear. For me,single-sex schools are much better,and the statistics show that they get better exam results,particularly at secondary level. Anything which helps children pass exams must be a good thing.
Message 3 — posted by Bill, USA
Boys and girls learn in very different ways. I feel that they should be educated separately so teachers can focus on their different needs. The way I see it is that if you have a zoo,you don，t put the lions in with the zebras!
Message 4 — posted by Martin,London
My view on this is that it doesn，t really matter. What is important is the curriculum (课程) , and keeping students interested. I was a teacher and we had a lot of truancy (逃学) to deal with,and problems with students missing lessons because they found them boring. Never have a timetable with Maths as the first class on Monday morning!
Message 5 — posted by Emily,Sydney
I don，t think there is any question that mixed schools are better. There is too much competition at single-sex schools,which often means that students don't make enough progress. I also think there is more bullying (欺凌) at single-sex schools, where children are picked on because of the increased competition. Single-sex schools lead to a “dog eat dog” situation.

B
We all know donating blood provides a vital lifeline to those in need,but a growing body of research suggests that it could have health benefits for the donor too.
Findings have shown that donating blood reduces the risk of heart attacks and even cancer.
It even bums quite a bit of energy — 650 calories(卡路里) for every pint (568 ml) given.
The news could come as a promotion (宣传) of British blood banks which use an average of 7 ,000units of blood every day.
It is thought that the benefits arise from- lowering high iron levels.
Iron affects how thick and sticky the blood is. High iron levels cause the blood to be thicker.
Raised iron levels also keep blood from flowing smoothly.
Because donating blood removes some of its iron,it may therefore have a protective benefit if done on a consistent basis by helping thin the blood.
According to a study from the Journal of the American Medical Association,researchers found that those aged 43 to 61 had fewer heart attacks when they donated blood every six months.
A study of 2 ,682 men from Finland found they had an 88 percent reduced risk of heart attacks than those who didn，t donate,reported Medical Daily.
Likewise,a study published in the Journal of the National Cancer Institute also links iron to an increased cancer risk.
The four-and-a-half-year study involving 1,200 people found those who made blood donations twice a year had a lower risk of cancer and death than those who didn’t.
However,these benefits depend on making donations on a regular basis,rather than once in a while.
Another side effect of donating blood is that it can bum a large number of calories too .
The University of California in San Diego says that for every one pint of blood donated,650 calories are burned as the body must fill itself up.
Although this seems to be an attractive effort-free way to lose weight,the NHS Blood and Transplant centre still encourages people to donate for the benefit of others first,rather than for themselves.
6. How can giving blood prevent heart disease?
A. By keeping blood from flowing fast.
B. By increasing blood's thickness.

D. By helping iron work better.
7. What is the healthiest way to donate blood?
A. Give blood regularly.
B. Give blood every six months.
C. Make donations in middle age.
D. Donate a small amount each time.
8. The author mentions the three studies to.
A. prove the serious harm of cancer

C. explain the reasons for heart disease
D. show the benefits of blood donations
9. According to the NHS Blood and Transplant centre,donating blood .
A. is an attractive way to lose weight
B. should be based on selflessness
C. involves some degree of risk
D. may bum too many calories
10. Which of the following can be the best title?
