专八阅读题2
相关文本:Inside an old factory building in Cambridge,Massachusetts,a remarkable machine with the improbable name Zeus is hard at work.Flexing its two robotic arms,the computer-driven device continually reaches into a storage container where thousands of individual samples of genetic material sit in tiny wells etched into plastic plates,each one identified by a unique bar code.
Then Zeus transfers each precious droplet to a nearby sheet of nylon,moistens a designated spot and pivots back to the glass plates to find the next sample on its list.When Zeus is done,the nylon sheet will be spotted with a grid of about 1,000 droplets,forming what researchers call a microarray.Once the machine has created a few dozen of these arrays,they will be rolled up ,inserted into glass tubes and doused with radioactive dye and genetic material from a range of human tissue types -from normal,healthy ceils to diseased cells representing breast,prostate,lung or colon cancer.Emerging from this experiment will be data that may someday lead scientists to a new cure for one of the deadliest scourges known to man.
When the human genome was sequenced last year,scientists finally gained access to the full test of God's reference manual.
14 According to the passage,Zeus____
A.is controlled by computer and decode the instructions of human genomes
B can automatically collect samples of DNA
C will roll the arrays up and insert them into glass tubes
D and its research is being done with the knowledge of the outsider world
以上是原文和我想问的问题.我认为C项正确.参考答案选了B.请大家帮我看看.
