    Cancer is a leading cause of death around the world. When it comes to cancer, the sooner you know you have it, the better your chances of surviving. A new blood test could change the way doctors and researchers find cancer in patients. Researchers say the test could provide evidence to the early forms of the disease.

Scientists at Swansea University in Wales came up with the idea. Gareth Jenkins is a professor at the university. “ In this blood test we don’t measure the presence of cancer; we measure the presence of mutant red blood cells which are collateral(附属的) damage that occurs---a by-product of the cancer developing.”

The researchers used normal laboratory equipment to perform the test. This equipment looks for changes in the structure of millions of red blood cells. Those mutant cells lack a surface protein that healthy cells normally have. “The main purpose of the test is to look for very rare cells which have picked up a mutation. The number of mutant red blood cells in a healthy person is around 5 or so per million. You have to look at millions of red blood cells to detect those rare events. These numbers increase in cancer patients---they go up to 40 or 50 mutants on average.”

The researchers tested blood from about 300 people, all of whom have cancer of the esophagus(食道). Patients with esophageal cancer have high levels of mutant red blood cells. Jenkins says that at this point he is not sure if other cancers will produce similar results.

The hope is that the new test and other non-invasive methods could one day become part of commonly used medical methods. He says that using a battery, or series, of tests will be the best way to find out if a person has cancer. These new technologies could save millions of lives.

1.According to the test, how do scientists find out if a person has cancer?

A.By calculating the speed of changes in the structure.

B.By observing the surface protein.

C.By looking for changes in the number of mutant red blood cells.

D.By measuring the presence of cancer.

2.What does the underlined word “mutant” in the 3rd paragraph mean?

A.Decreased. B.Changed. C.Increased. D.Multiplied.

3.The author adopts a/an        tone in the passage.

A.humorous B.favorable C.critical D.objective

4.In which section of a website can you most probably find the passage?

A.Health. B.Fashion. C.Education. D.Culture.

 

1.C 2.B 3.D 4.A 【解析】 这是一篇说明文。文章作者客观的介绍了一种新的检测癌症的方法,并且希望新的测试和其他非侵入性的方法有一天能成为常用的医疗方法的一部分。 1. 细节理解题。根据第二段In this blood test we don’t measure the presence of cancer; we measure the presence of mutant red blood cells which are collateral(附属的) damage that occurs---a by-product of the cancer developing.(在血液测试中,我们不测量癌症的存在;我们测量突变红细胞的存在,这是发生的附带损害——癌症发展的副产品。)和根据第三段The number of mutant red blood cells in a healthy person is around 5 or so per million.(健康人体内突变红细胞的数量约为百万分之五左右。)以及These numbers increase in cancer patients---they go up to 40 or 50 mutants on average.(这些数字在癌症患者中增加——平均上升到40或50个突变体。)由此可知,根据这项测试,科学家通过寻找突变红细胞数量的变化,来发现一个人是否患有癌症。故选C。 2. 词义猜测题。根据第三段This equipment looks for changes in the structure of millions of red blood cells.(这种设备寻找数百万红细胞的结构变化。)可知划线词所在的句子Those mutant cells lack a surface protein that healthy cells normally have.意思是这些被改变的细胞缺乏一种正常健康细胞拥有的表面蛋白。“mutant”意思是突变的,A. Decreased.减少的;B. Changed.改变的;C. Increased.增长的;D. Multiplied.乘。故选B。 3. 推理判断题。根据最后一段The hope is that the new test and other non-invasive methods could one day become part of commonly used medical methods. He says that using a battery, or series, of tests will be the best way to find out if a person has cancer. These new technologies could save millions of lives.(希望新的测试和其他非侵入性的方法有一天能成为常用的医疗方法的一部分。他说,使用电池或一系列测试将是查明一个人是否患有癌症的最佳方法。这些新技术可以挽救数百万人的生命。)结合全文内容,可知作者客观的介绍了一种新的检测癌症的方法,所以作者在这篇文章中采用了客观的语气。故选D。 4. 推理判断题。第一段A new blood test could change the way doctors and researchers find cancer in patients.(一种新的血液检测方法可能会改变医生和研究人员在病人身上发现癌症的方式。)是全文的主题句,结合全文,可知这是一篇关于测试癌症的最新科学研究报道,所以你最可能在网站的“健康”部分找到这篇文章。故选A。

    Simply being quiet is a growing appeal. Lots of business have appeared to meet a rising demand for quiet time, from silent weekend getaways to silent dining, silent reading parties and even silent dating. Silence can mean different things to different people. We are usually silent only with those closest to us. So there is something almost radical(不同凡响的)about the recent trend towards enjoying silence with strangers.

Mariel started a regular silent reading party in Dundee just under a year ago. Readers bring their books and meet in a bar, where they read together in silence for an hour or sometimes two and then put their books away to chat and have a drink. “When the reading party starts, everything goes quiet,” says Mariel, “ It’s a little bit surreal (超现实的), especially in what is usually a noisy bar. However, there is something special about sharing the silence with others. It offers a chance to escape from reality; everyone is so busy with work and with technology being ever present. An event like this gives people the opportunity to escape these things for a while.”

Honi Ryan is an artist based in Berlin who began hosting silent dinner back in 2006. The rules of the dinner are: no talking, no using your voice, no reading or writing, trying to make as little noise as possible, not connecting with technology, and staying for at least two hours. So far she has taken her silent dinner project to Mexico, the US, Australia and China. “It’s evident that the age-old connections we make over food do not depend on the words around it. Silence creates the space for the people and places involved to fill with whatever is needed; it is quite different from our usual social behaviors.”

1.Why have lots of silent businesses appeared?

A.To satisfy people’s demand for silence.

B.To make people get close to each other.

C.To appeal to young people.

D.To change people’s old way of life.

2.What can we learn about Mariel’s silent reading parties?

A.Readers can use their voice while reading.

B.Readers can be busy with their work.

C.Readers can connect with technology.

D.Readers can chat and drink after reading.

3.The underlined word “it” in the last paragraph refers to       .

A.noise B.space C.silence D.food

4.What can be a suitable title for the text?

A.Escape from Reality. B.Enjoying Being Quiet.

C.Silent Reading Parties. D.Silent Dining Projects.

Travel Journal

Friday

We arrived in Paris on Friday lunchtime and went straight to our apartment. We then went for a walk around our area and realized how close we were to the centre of Paris. It only took us 20 minutes to walk to the Louvre. After a walk around the Tuileries Gardens, we went for afternoon tea in a café called Angelina which has the most delicious hot chocolate. After warming up we then walked along to the big department store Printemps, on the top floor where you get a wonderful view of Paris (this was free). We walked along a street called Grands Boulevards which was beautiful with all its Christmas lights. The shops on this street are famous for their Christmas window displays. In the evening we cooked at the apartment and went to a Scottish pub which was funny as two of my friends are Scottish.

Saturday

In the morning we went for brunch (a meal between breakfast and lunch) at a really cool café called FAB (French American Bakery). We had waffles with bacon and fresh carrot and ginger juice. We found out that we were really close to a chocolate museum, so of course we took a visit--- who doesn’t love chocolate! In the afternoon we went to a Christmas market with unique handmade gifts and crafts. In the evening we ate at a Tunisian restaurant and had roast chicken and vegetable stew with couscous. It was delicious and the restaurant was in a cute little lane.

Sunday

On Sunday we went for breakfast at the same café and we caught our train back home at midday, carrying shopping bags full of lovely presents that we had bought at the Christmas market. We had a great weekend in Paris. Exploring this beautiful city with no plans was an unusual but great idea as we got to do things we wouldn’t normally discover. I highly recommend spending a weekend somewhere trying to be a local!
