Elizabeth Blackwell was born in England in 1821, and moved to New York City when she was ten years old. One day she decided that she wanted to become a doctor. That was nearly impossible for a woman in the middle of the nineteenth century. After writing many letters asking for admission（录取）to medical schools, she was finally accepted by a doctor in Philadelphia. She was so determined that she taught school and gave music lessons to get money for the cost of schooling.
In 1849, after graduation from medical school, she decided to further her education in Paris. She wanted to be a surgeon（外科医师）, but a serious eye problem forced her to give up the idea.
Upon returning to the United States, she found it difficult to start her own practice because she was a woman. By 1857 Elizabeth and her sister, also a doctor, along with another woman doctor, managed to open a new hospital, the first for women and children. Besides being the first woman physician and founding her own hospital, she also set up the first medical school for women.
28．Why couldn't Elizabeth Blackwell realize her dream of becoming a surgeon？
A．She couldn't get admitted to medical school.
B．She decided to further her education in Paris.
C．A serious eye problem stopped her.
D．It was difficult for her to start a practice in the United States.
29．What main obstacle（障碍）almost destroyed Elizabeth's chances for becoming a doctor？
A．She wrote too many letters. B．She was a woman.
C．She couldn't graduate from medical school. D．She couldn't set up her hospital.
30．How many years passed between her graduation from medical school and the opening of her hospital？
A．Ten years. B． Eight years.

Did you know that the colour of uniforms can influence the performance of an athlete？ It may sound strange, but a study suggests this might be true.
Two British scientists studied the results of four sports in the 2004 Athens Olympic Games where the athletes had been given either a red or a blue uniform. They discovered that when there was a big difference in the score, colour had no influence on the result. But if it was a close match, the athlete in a red uniform was more likely to win. Then they looked at the
uniforms of the soccer teams at the Euro 2004 Tournament. Again, teams wearing red won more games.
The two scientists got their idea from earlier studies of wild animals. It had been discovered that when a male shows red on its body, it sends a signal of its power and strength. For example, in many kinds of monkeys, the more the male shows off its red scars, the more females it can attract.
Based on this fact, the British scientists thought that the idea might work for humans, too. According to them, when an athlete sees a competitor in a red uniform, he gets a feeling that his competitor could be stronger than him. And that kind of feeling may have a bad influence on the player's performance in the actual game.
Although the idea is interesting, most people don't accept that colour signals in the animals world can really be useful to humans in sports. They think that it is unreasonable to develop an idea based on such a small number of examples. Much more research has to be done to prove the influence of uniform colours on the performance of athletes.
32. What did the scientists find out about the 2004 Athens Olympic Games？
A.Athletes played equally well in four sports.
B.Game results had a big influence on the athletes.
C.There was a big difference in red and blue teams' scores.
D.Athletes dressed in red scored more in a close match.
33. What may the red scars of a male animal suggest？
A.It is quite strong.
B.It is a failure.
C.It has power over other males.
D.It has attracted a lot of females.
34. The underlined part “that kind of feeling” in the text refers to a feeling of .
A.pride
B.weakness
C.danger
D.shame
35. What is most people's opinion on the scientists' idea？
A.Interested.
B.Satisfied.
C.Doubtful.
D.Thankful.

A class teacher, in my opinion, plays an important role in a child's development. 36 This year, she is moving to Class Three and I can't wait to see how things are going on.
Last year, my daughter did not like her teacher at all. It was so bad that she did not look forward to school. It was a year full of trouble and that worries me.
This year, Miss Purity is gentle and humorous. It's hard not to like her.37
She becomes an early bird. Last year, mornings were like a fight because I had to force Tasha to hurry up when she was preparing for school. I had to pull her out of bed, tell her to take breakfast and then drove her to school. But now, our mornings are like a party. She wakes up early, prepares everything at a high speed and then rushes to school to be with Miss Purity.
She's happy. She enjoys school and schoolwork and keeps talking about what they did at school when she comes home.
She's responsible. 38 But now she never forgets even her water bottle at school. She makes her bed and helps in the kitchen.
Her diary is full of praises. The diary is the tool of communication between the teacher and the parents. Last year, her diary was always full of negative reports. One time, she poured water in a child's lunch box, another time she threw another kid's textbook in the toilet. 39 She's always volunteering to clean the blackboard, the teacher's chair and desk.
40 .Finishing her classwork was such a big problem. She had to do it at home. But now, she finishes both the classwork and homework at school.
A.Here are the changes in my daughter.
B.Now she begins to share her snacks with those who don't have anything.
C.Every year when my daughter moves to a new class, I have a usual big worry—her new class teacher.
D.Her diary was good.
E.She has a good class teacher.
F.She used to be careless and forgetful.
G.She does well in school.

Good morning,everyone!It is my honour to be here to share with you my opinions on what
to learn in senior high school.
In the coming three years, our school life will be challenging. First, we should learn to study in a proper way. Personally, I will try my best to achieve my ideal results. Developing a good habit is also of importance. It really benefits us a lot to preview lessons,take an active part in class, and go over what has been taught after class. In addition, we should learn how to get along well with others. I n school, we’d better participate in sports and outdoor activities frequently. They are really helpful to build up our body and enrich our school life. So I suggest that we should learn to keep a balance between our study and life.
No pain, no gain. I am sure that with great efforts, we will enjoy a colourful and fruitful life here.
Thank you!
