四川省乐山市沫若中学2019届高三上学期英语(9月)入学考试试卷

阅读短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。

    Scientists around the world are striving for effective detection of cancer in the early stages, which is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body, and a Chinese scientist may have found a quick way of knowing whether malignant tumors (恶性肿瘤) exist in a patient's body, with just one drop of blood.

    Malignant tumors in early phases can be cured. However, it's extremely difficult to be aware of cancer in its early stages, as patients don't show obvious symptoms and thus it can only be found in its later stages, which is already too late, so to detect cancer early remains a global challenge for scientists.

    Back in 1989, scientists have found a kind of heat shock proteins (HSP), named Hsp90α, which existed in human bodies and can be used as a cancer biomarker detection kit. Scientists around the globe have been working on it since then, and more than 10, 000 journals have been published on accredited magazines, yet no one has actually turned their research results into medical products.

    However, Luo Yongzhang and his team in Tsinghua University's School of Life Sciences in Beijing seemed to have cracked the code, after working on the problem since 2009.The team has produced an artificial Hsp90α protein for clinical use that gains structural stability by regrouping proteins. The test kit can diagnose multiple kinds of cancer by analyzing a drop of human blood. This means they are able to "create" the protein, in any quantity, and at any time they wish to.

    The kit has since been used in clinical trials involving 2, 347 patients at eight hospitals in China. It was the first clinical trial in the world to test if the protein could be a useful tumor biomarker for lung cancer, and it succeeded. Now, the kit has been approved to enter the Chinese and European markets, 24 years after Hsp90α was discovered.

(1)、Why is cancer hard to cure?
A、Malignant tumors are found too late. B、Malignant tumors spread too quickly. C、Its symptoms are shown in early stages. D、No proper treatment can be applied to it.
(2)、What do we learn about Hsp90α from Paragraph 3?
A、It was created by scientists in 1989. B、All magazines have covered the topic. C、There has been a medical product about it. D、It can serve as a cancer detection approach.
(3)、How does the Chinese kit diagnose cancer?
A、By regrouping proteins. B、By cracking cancer's code. C、By breaking down one drop of blood. D、By producing an artificial Hsp90α protein.
(4)、It can be inferred that a European with lung cancer in early phases ________.
A、can't be cured in the end B、can be diagnosed with it in time C、has to be examined in China D、expects the kit to come into the market

How Super AreSupermarkets?
Buying eweek's groceries is tiring. You want to get it over and done with quickly, soyou head for the nearest supermarket, you find everything you need under oneroof, and you feel glad that those days of going in and out of different shopsin the high street are over. Supermarkets seem to be a big plus. There is adownside, though.
In the UK 90%of all the food people consume is bought at 5 different supermarket chains.This makes these companies extremely powerful, which lets them use their hugebuying power to squeeze small suppliers to get the best deal. Milk is a goodexample. Supermarkets like to use things like milk, which is the top of almosteveryone's shopping list to attract customers. To offer the lowest pricepossible to the consumer, the supermarkets force dairy farmers to sell milk atless than the cost of production. Supermarkets guarantee their good profitswhile farmers are left struggling to make ends meet, and the taxpayer pays tosupport the system without even knowing it.
It would be niceif local grocers supported local agriculture. But for the big supermarkets thisjust doesn't make sense. Supermarkets don't want little farmers thinking theycan decide prices. So supermarkets have started a global search for thecheapest possible agricultural produce. In many supermarkets it is difficult tofind anything which is produced locally.
UK farmersused to grow a lot of apples. Not anymore. In 1999 36% of apples were imported.By 2015 the figure had risen to 80% and the domestic production of apples hadfallen by two thirds. The consumer might just be happy to get a reasonablypriced meal made up of foods from Thailand, Spain, Italy and Zambia, but weshould also bear in mind the Influence on local producers.
Then there'spackaging. Supermarkets like everything to be packed and wrapped so it can bepiled neatly on shelves. Supermarkets produce nearly 10 million tons of wastepackaging in the UK every year, of which less 5%is recycled. Some supermarketsmake sure that large recycling bins are obvious in their car parks, showingthat they are environment-friendly. But that is just an image.
When a newsupermarket is planned there are claims about the number of new jobs that willbe created. Unfortunately, the number of jobs lost in the area is larger thanthe number of new positions in the supermarket. On average each new supermarketleads to the loss of 276 jobs.
However, themodern world is all about shopping, and the freedom to buy whatever you what,so it would be impossible to stop people shopping at some particular kind ofshop. But some measures do need to be taken when small suppliers lose profits,local producers suffer, sea levels rise and jobs are lost, anyway, we can'tjust care about a free car park and special offers.

    Reuel Tolkien (1892 ~ 1973), the British linguist, writer. He created a fantasy novel “The Lord of the Rings”, the well-known trilogy (三部曲).

    Tolkien was born in Bloemfontein, South Africa. When he was 4 years old, his father died and his family moved back to England. Tolkien graduated from Oxford University when he was 23 years old, and participated in the First World War. During the war, Tolkien suffered from “trench fever” and stayed in the hospital until the end of World War I. It was the days in the hospital that he began his writing career first.

    After the war, Tolkien became a linguist. He was an edition of the “New English Dictionary” of 1918 ~ 1920. However, he was more researching to Anglo-Saxon language which makes his extensive contacts in Britain and the Nordic spread all over the folklore and mythology.

    In 1937, Tolkien completed his first work “The Hobbit”. Although this was a fairy tale, it was also suitable for adults to read. Because of good sales, publishers (Allen & Unwin) convinced Tolkien to write its sequel. This encouraged Tolkien to complete his most famous works the epic (史诗) trilogy “The Lord of the Rings”. The works of writing went on for almost a year with the support from his good friend Lewis.

    At the beginning “The Lord of the Rings” was similar works for children, but after that writing style quickly became serious and dark. “The Lord of the Rings” was one of the most popular literary works in the 20th century in terms of sales and readers' evaluation. Tolkien's influence is important, for the success of “TheLord of the Rings” makes the fantasy novels of this literature genre (体裁) developed rapidly.

    E-mail systems at thousands of companies and government offices around the world were attacked by a virus(病毒)called “Melissa” that disguises(伪装)itself as an “important message from a friend. In spite of a weekend of warnings,more than 50 000 computers at about 100 places around the world have been attacked by the virus,computer security experts said on Monday.

    The virus began to show up last Friday and spread rapidly on Monday by making computers fire off dozens of infected(被传染的)e-mails. Although the virus causes no serious damage to a computer,its effect was far reaching.

    To make matters worse,a similar virus called “Papa” was discovered on Monday. Papa is programmed to send out even more infected e-mails than Melissa.

    The Melissa virus comes in the form of an e-mail,usually containing the subject line“Important Message”. It appears to be from a friend. The body of the e-mail message says,“Here is that document you asked for...,don't show it to anyone else.” Attached(附)to the message is a document file.

    Once the user opens that file,the virus digs into the user's address book and sends infected documents to the first 50 addresses. E-mails from the Papa virus include an attached spreadsheet(电子数据文件)file. When the user opens that file,the virus sends 60 infected e-mails.

    The reason why this is spreading so fast is that you are getting it from people you know. You should never open documents or attachments from people you don't know. People who get an unexpected e-mail with the “important message” subject line should delete it immediately and not open the message.
