Directions: Read the following passage carefully and then translate
each underlined part into Chinese.
21. Every time you try to answer a question that asks why, you engage in
the process of causal analysis--you attempt to determine a cause or series of
causes for a particular effect. When you try to answer a question that what if,
you attempt to determine what effect will result from a particular cause. You
will have frequent opportunity to use cause- and-effect analysis in the writing
that you will do in college. For example, in history you might be asked to
determine the causes of the Seven Day War between Egypt and Israel. In political
science you might be asked to determine the reasons why Ronald Reagan won the
1984 Presidential election. And in sociology you might be asked to predict the
effect that changes in Social Security legislation would have on senior
citizens.
22. Determining causes and effects is usually

Can Gene Technology Make Human Smarter?
Almost everyone wants to get smarter. To achieve that,some choose to do exercise,others choose to take in more nutritions good for brains.Princeton neurobiologist Joseph Z.Tsien possibly found a different way to make it. In September he announced that he'd built a better mouse by altering a gene that affects learning and memory.A similar process of gene manipulation might conceivably be used one day to boost intelligence in humans.
The key of this technology lies in a feature of brain cells called the NMDA receptor,which Tsien likens to a cylindrical tube or window that mediates the flow of information.When the window is open,chemicals called neurotransmitters flow through easily and memory is registered and stored. But as organisms mature,the window begins to close.(This may explain why children lose their facility for learning new languages when they reach sexual maturity and why some people suffer memory loss as they age.)
Tsien also found out that the receptor worked more efficiently if it is teamed with the gene NR2B,so he introduced extra NR2B genes into a batch of fertilized mouse eggs.In a normal mouse,the memory window is open for just 150-thousandths of a second.In Tsien's specially engineered mice,the window opens for 250-thousandths of a second,long enough to make a remarkable difference in memory retention.When he pitted his mice against common mice,they won paws down.Ordinary mice could recognize a Lego block for 12 hours,but smart mice could remember the block for up to three days."That's a profound enhancement,"Tsien says.
Can this technology be applied to humans?Maybe,but genetic engineering will have to make some extraordinary advances first. And some thorny ethical issues will have to be resolved. Mean-while,Tsien promises to keep his furry little geniuses locked up in a lab,far from your larder. "Otherwise,"he says,"you might need a smart cat or a smart mousetrap to catch them."
What did Tsiens refer to by saying"That's a profound enhancement"?(Line 7,Para. 3)
A.His smart mice can remember much longer than the ordinary ones.
B.People reach sexual maturity.
C.Tsien found a different way to enhance memory.
D.Tsien applied this technology to human.
