Early screening for breast, colorectal and cervical cancers can help prevent 30 percent of cancer cases.Breast, colorectal, lung, gastric and thyroid cancers are the five most common cancer forms among women, with breast cancer accounting for 16 percent of Shanghai's new cases each year and colorectal cancer 13 percent. Cervical cancer, although only the 12th leading cancer in women in Shanghai, is particularly common among women between 25 and 54 years old. Dr Zheng Ying, director of the center's tumor prevention and control department, said , "breast, colorectal and cervical cancers accounted for 32 percent of female cancers”. He added, " However, the three types of cancer can be detected and treated properly through early and regular screening. Our main target of women's cancer prevention education this year is breast cancer, cervical cancer and colorectal cancer."The prevention and control of colorectal cancer will be a new public health project this year with the city government promoting a community-based screening program.Experts say women over 20 should examine their breasts every month and have annual clinical checks after the age of 35. Women over 50 should have mammograms(乳房X线照片) every two years. For cervical cancer, women over 20 should be checked every three years. Women over 50 years old should have annual medical checks. Zheng said anyone with a family history of the three types of cancer should be aware of the need for more frequent examinations and early screening.41. What is the best title of the passage?A.

She is one of 26 bloggers for SPARK, an international group founded in 2010. The group fights the use of the female body as a marketing tool in the media.Alice found out about SPARK when the organization launched a campaign demanding Seventeen Magazine feature a more diverse group of models. She applied to be a blogger for the group in May and won one of the positions.Each month, Alice pitches (为…做宣传) her girl –and women – centric blog post ideas via online chat to an editor at SPARK. So far, she has written about topics such as female actresses, choosing what to wear, and dealing with anger.Alice said she hopes large companies and media stop editing images of women. Increases in bust (胸部) size, decreases in waist size, smoothing and whitewashing skin are what Alice notes. “We want them to know that these images are bad for our development,” Alice said. “Three out of four teen girls feel bad abou t themselves after reading a fashion magazine for three minutes,” she said, according to SPARK’s research.Alice first felt it necessary to advocate (倡导) for women in the fifth grade, after seeing a girl’s T-shirt with writing on the front that read: “Who needs brains when you have these?”“I was raised with this idea that if you don’t like something, you can change it,” Alice said. So Alice started following feminist bloggers.Alice juggles class work with blogging and creating videos and serves aseditor-in-chief of her school’s newspaper. It is amazing that she can handle everything well at the same time.She’s also focused on creating projects that aim to inspire girls – like designing a “girl power bathroom” at her school. The newly designed third-floor restroom is completed with pastel paint colors and inspirational (启发人的) quotes from women around the world.“Sisterhood is powerful,” Alice said. “It can make you feel less alone.”46. Which of the following is the correct order of events, according to the article?a. Alice helped design a “girl power bathroom”.b. Alice first felt it necessary to advocate for women.c. SPARK launched a campaign asking Seventeen Magazine to feature a more diverse group of models.d. Alice applied to be a blogger for SPARK.e. Alice started reading feminist bloggers.A. b–e–c–a–dB. b–e–c–d–aC. c–d–e–b–aD. c–e–b–d–a47. The underlined word “juggle” in the article probably means ______________.A. to deal with several tasks at onceB. to change one’s original planC. to pay more attention to somethingD. to lose one’s interest in something48. We can infer from the last three paragraphs that Alice ___________.A. often feels lonely in her fightB. often advises schoolmates on what to wearC. believes that her efforts could change the lives of many girlsD. puts more energy into her school’s newspaper than her study49. This article is mainly about ____________.A. what being a feminist means in today’s American societyB. Alice Wilder’s participation in feminist activitiesC. how girls and women fight for their rights in the USD. the ways that the US media misleads girls50. From the article, we can conclude that Alice Wilder ___________.A. is a successful feminist blogger with hundreds of followersB. believes that teenage girls shouldn’t read fashion magazinesC. doesn’t think that girls or women should look sexyD. is a critical thinker and works hard for her goals第二节(共5小题:每小题2分,满分10分)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项中有两项为多余选项。

The young girl carefully released the Butterfly. Instead of flying away, the little butterfly changed into a beautiful fairy. The young girl rubbed her eyes in disbelief.“For your wonderful kindness,” the good fairy said to the girl, “I will give you any wish you would like.” The little girl thought for a moment and then replied, “I want to be happy.”The fairy leaned toward her and whispered in her ear. Then the fairy disappeared.As the little girl grew up, there was no one in the land as happy as she. Everyone asked her secret of happiness .She would only smile and answer, “The secret of my happiness is that I listened to a good fairy when I was a little girl.”When she was very old and on her deathbed, the neighbors all gathered around her, that her unbelievable secret of happiness would die with her. “Tell us, please,” they begged, “Tell us what the good fairy said.” The lovely old woman simply smiled and said, “She told me2that everyone, no matter how secure they seemed, no matter how old or young, how rich or poor, had need of me.”56. ______ the girl felt sad and lonely.A. There were many friends butB. There was nobody to love her soC. There was nothing to doD. Seeing the butterfly was caught57.

The butterfly ______ after was saved by the little girl.A. flied awayB. still diedC. changed into a fairyD. was more beautiful than before59. The only thing that the little girl wanted was________.A. to be richB. to have her own parentsC. to have a lot of friendsD. happiness60. The neighbors all gathered around the old happy woman when she was dying, because__.A. they loved this woman deeply and they didn…t wanted her to d ieB. the woman had lots of money to be shared as soon as she diedC. they wanted to know the secret of her lifetime happinessD. they wanted to pray for her after her deathBScientists have tried to come up with biological explanations for the difference between boys and girls.However, none were believable enough to explain the general picture. As one scientist points out, “There are slight genetic(遗传的) differences between the sexes at birth which may affect the subjects boys and girls choose. But the difficulty is that by the time children reach school age, there are so many other effects that it is almost impossible to tell whether girls are worse at science and maths, or whether they've been brought up to think of these subjects as boys‟… territory‟”.Statistics(统计数据) show that in mathematics, at least, girls are equal to boys. A recent report suggests that girls only stop studying mathematics because of social attitudes. One of the reports‟ authors says, “While it is socially unacceptable for people not to be able to read and write, it is still acceptable for women to say that they are …hopeless‟ at maths. Our research shows that, although girls get marks which are as good as the boys‟, they have not been encouraged to do so.”The explanation for the difference, which is very clear during the teenage years, goes asfar back as early childhood experiences. From their first days in nursery school, girls are not encouraged to work on their own or to complete tasks, although boys are. For example, boys and not girls, are often asked to …help‟ with repair work. This encouragement leads to a way of learning how to solve problems later on in life. Evidence shows that exceptional mathematicians and scientists did not have teachers who supplied answers; they had to find out for themselves.A further report on maths teaching shows that teachers seem to give more attention to boys than to girls.Most teachers who took part in the study admitted that they expect their male students to do better at mathematics and science subjects than their female students. All of this tends to encourage boys to work harder in these subjects, gives them confidence and makes them believe that they can succeed.Interestingly, both boys and girls tend to regard such …male‟ subjects like mathematics and science as difficult. Yet it has been suggested that girls avoid mathematics courses, not because they are difficult, but for social reasons.Mathematics and science are mainly male subjects, and therefore, as girls become teenagers, they are less likely to take them up. Girls do not seem to want to be in open competition with boys. Neither do they want to do better than boys because they are afraid to appear less female and so, less attractive.61. The underlined word“territory” in the second paragraph most probably means “ ”.A. interestB. area of landC. special fieldD. district62. According to scientific studies, ________.A. maths is not fit for girls to learnB. boys have a special sense of mathsC. girls are poorer at maths because they are the weaker sexD. girls can learn maths as well as boys if given enough encouragement63. Those who made extraordinary contribution(贡献) in mathematics and science .A. usually had good teachers to help themB. had the abilities to solve problems by themselvesC. usually worked harder than othersD. were encouraged to repair things when young64. Which of the following is not true according to the text?A. It seems socially acceptable for a girl not to be able to read and write.B. It is a social problem rather than a problem of brains that girls are poor at mathsC. Mathematics and science are no easy subjects to either girls or boys.D. There is no connection between a girl's ability in maths and her appearance.65. What would be the best title for the text?A. Who‟s Afraind of Maths Anyway?B. Are Boys Cleverer than Girls?3C. Boys Are Better at Maths than Girls by BirthD. Maths-A Difficult Subject班级:___________ 姓名:___________ 得分___________II卷(共55分)I.
