Is human blood all the same? “Yes.” You may say, “It’s all red.” Well, it’s not as simple as you might think.

Blood is made up of different parts, such as red blood cells（红细胞）, white blood cells and platelets(血小板).

Two chemical molecules（分子）on the red blood cells make people’s blood different. Scientists mark one molecule “A” and the other molecules “B”. According to which an how many molecules are on the red cell, scientists divide blood into four types: A, B, AB, O. Scientists have been wondering if there are some links between people’s blood

types and their personalities, but they don’t know for sure yet. But some say that people with the same blood type may have things in common. People with type A: They look peaceful from the outside. But they ask too much of

themselves so that they may be very nervous inside. They get happy or sad easily.

Sometimes they are shy but always very careful. They can easily win people’s trust.

People with type B: They have strong minds. Once they start a task, they don’t give

up easily. They’ll try their best to finish it and do it well. Type B people always try to

make themselves different from others. They want to do things in their own way.

People with type AB; They are maybe the strangest among all blood types. They

can be both open and shy , noisy and quiet at the same time. They are responsible and

always ready to help others.

People with type O: They are open and good at making friends. They always start

tasks but don’t always finish them. They have lots of new ideas and love to be the center of attention. They always strongly believe in themselves.

What does it take to graduate (毕业) from a university? Many may say all you have to do is to take classes and pass the exams. Well, it is not enough if you're a student at Tsinghua University.　　　　

Starting this September, students at the university will have to take swimming courses, If they fail a swimming test at the beginning of their university course, they won't receive their degree (学位) until they can pass the test successfully. But students with certain physical or mental (心理的) illness are not included. Why does the university connect swimming ability with degrees? Liu Bo, head of the Division of Sports Science and Physical Education, explained, "As a necessary living skill, swimming is helpful in improving students' endurance (耐力). And students don't get hurt easily when doing the water sport." Considering the ability to swim as a must for students is not something new to this university-it was also necessary in the early 20th century. It was later dropped because of a rising number of students. Another reason is that there were not enough swimming pools. Besides Tsinghua University, Peking University and Xiamen University, have also listed swimming as a compulsory course for students.

However, the rule made by Tsinghua University has caused a heated discussion. Some welcomed the new rule, saying it's a necessary skill that can save lives in unexpected and dangerous situations as well as a way to stay healthy. However, some said it has nothing to do with getting a degree. It's not reasonable to ask people to be able to swim for them to graduate, especially for a lot of people who grew up in inland (内陆) cities, learning how to swim as an adult will be difficult. In fact, Chinese universities are not the only education organizations that encourage their students to swim. A few colleges in the. United States-including Cornell University, Columbia University and MIT-provide swimming classes for students, too. They believe that anything that stops people from dying needlessly is a valuable skill.

1.Besides Tsinghua University, another _______ universities encourage their students to swim.

A.2 B.3 C.5

2.From this passage, we can learn that at Tsinghua University, _______.

A.students are expected to learn some living skills

B.all the students have to take a swimming course

C.students can graduate as long as they get good grades

3.The underlined word "compulsory" means _______ in Chinese.

A.选修的 B.无关的 C.必修的

4.As for the discussion in paragraph 3, which statement is NOT mentioned?

A.It's helpful and healthy to learn to swim.

B.Swimming will get in the way of students' study.

C.Learning to swim should not be a must for getting a degree.

5.What can we infer from the passage?

A.All universities believe' that swimming is the most important skill.

B.Students at Tsinghua University had to take swimming courses in the 1910s.

C.It is much, easier for an adult who grew up in Chengdu to learn to swim.

The hardest thing in the world is saying 'yes' to the world. Do you say yes to the world？Most of us have a habit of saying no to the things we don't like and yes to the things we like. However，everything we face is our life. We won't say yes to the things we do not like，because we are afraid that we will not avoid them forever.

But in fact，only through accepting the existence（存在）of what is not working for us，we can begin to change. When we say yes to the world，we begin to believe whatever our situation is，we can work with it. We express belief in ourselves，and the world. We also express a willingness to learn from whatever happens to us，rather than running and hiding when we don't like what we see. Therefore，in one word，saying yes is really good for our life.

What will it take to get to the point of saying yes? For some of us, it means dealing with something we can't run away from or refuse, and so we have no choice but to say yes. For others. they might make a decision to say yes to life no matter what happens to them. Saying yes to life might be difficult at first, and even painful at times. However, if we continue to say yes to life, it will be far less difficult in the end. And we will find the joy of being in an active talk to the world with a very powerful word ' yes'. We should say yes to everything that life puts in front of us.
