二、英譯中：Translate the following English passage into Chinese.（30 分）A commonly held notion is that intelligence is 'static' by the age of about 18. Currentscientific consensus suggests that intelligence is controlled by genes, with environmentalfactors such as schooling and nutrition playing a part up to this age. After this point, IQscores stabilize. A new study challenges this notion. It shows that intelligence is not fixedbut can be boosted throughout adulthood. Stimulating households where people talk, makejokes and challenge each other can boost IQ levels by several points, as can jobs thatmentally energize employees. The key is that intellectual stimulation from others is crucialas the brain seems to be rather like a muscle – the more you use it, the stronger it gets.
