12.A MAJOR breakthrough that could save many lives could be coming,as a simple blood test from genomics (基因組學(xué)) company Illumina could help to detect (發(fā)現(xiàn))cancer early.
The company,helped by $100 million (about 658 million yuan)from famous tech founders like Bill Gates and Jeff Bezos,aims to find warning signs of any type of cancer before there are any symptoms or tumors (腫瘤),and thus save many lives,according to The Telegraph.
The race to invent this type of technology is happening between several scientists.For example,the Cancer Research UK Manchester Institute and the University of Leicester in the UK are both working on similar technologies.
Although some blood treatments that show tumors returning or cancer getting worse have been developed,scientists have been trying for some time to find cancer signs in people that otherwise seem healthy.The technology,called"liquid biopsy",would work by finding parts of DNA that are known to be signs of cancer in the blood as the disease developed.
Catching cancer early isn't always a good thing-some cancers never go on to become dangerous,but treating them can have bad side effects.However,Jay Flatley,the Illumina chief executive and chairman of Grail,a company set up by Illumina,told The New York Times that Grail will solve these issues by sequencing(確定…的順序)the DNA of 30,000 to 50,000 people.It will check how serious their cancers are over time to make the test accurate.The money of a large company like Illumina means that its DNA sequencing technologies are far more accurate than the average ones.
At the University of Leicester,researchers such as Professor Jacqui Shaw are also trying to solve the problem by analyzing bits of DNA for errors that are only related to fast-progressing tumors.
"We hope today is a turning point in the war on cancer,"said Flatley."By making it possible for cancer to be detected early in people with no symptoms through a simple blood test,we aim to greatly decrease cancer deaths by finding the disease at a stage when it can be cured."
Last year,a similar test created in London by the Institute of Cancer Research was able to tell if breast cancer was coming back almost eight months before any symptoms were found.

A.has invented a new medicine to cure cancer

分析 本文是一篇科教類閱讀,主要介紹了一種能夠通過簡單的血液測試來提前探測癌癥的新方法.有了這種方法,癌癥患者能更早的治療并挽救生命.
解答 59:D考查細(xì)節(jié)推理,根據(jù)文章第一段的 a simple blood test from genomics (基因組學(xué)) company Illumina could help to detect (發(fā)現(xiàn)) cancer early.來自基因組學(xué)公司Illumina的簡單血液測試就能幫助人們早發(fā)現(xiàn)癌癥.可知本題答案為D選項(xiàng).
60:C考查細(xì)節(jié)推理,根據(jù)文章第五段的The money of a large company like Illumina means that its DNA sequencing technologies are far more accurate than the average ones.像Illumina一樣的大公司的資金意味著它的DNA序列科技遠(yuǎn)比平均的要準(zhǔn)確.可知資金在該研究中很重要,故本題答案為C選項(xiàng).
61:A考查主旨大意,本文主要介紹了一種能夠提前探測癌癥的新方法.有了這種方法,癌癥患者能更早的治療并挽救生命.結(jié)合選項(xiàng),故本題答案為A選項(xiàng).
點(diǎn)評 本文是一個科教類閱讀,題目涉及多道細(xì)節(jié)理解題,做題時結(jié)合原文和題目有針對性的找出相關(guān)語句進(jìn)行仔細(xì)分析,結(jié)合選項(xiàng)選出正確答案.推理判斷題也是要在抓住關(guān)鍵句子的基礎(chǔ)上合理的分析才能得出正確答案,切忌胡亂猜測,一定要做到有理有據(jù).
