题目内容
什么是中国诗的一般印象呢提这个问题的人一定是位外国读者，或者是位能欣赏外国诗的中国读者。一个只读中国诗的人决不会提出这个问题。他能辨别，他不能这样笼统地概括。他要把每个诗人的特殊、独个的美一一分辨出来。具有文学良心和鉴别力的人像严正的科学家一样，避免泛论、概论这类高帽子、空头大话。假如一位只会欣赏本国诗的人要作概论，他至多就本国诗本身分成宗派或时期而说明彼此的特点。他不能对整个本国诗尽职，因为也没法“超以象外，得其环中”，有居高临远的观点。 本段文字意在说明______。

Five and a half years into his presidency, George Bush finally vetoed a bill this week. Oddly enough, it was one that most Americans support: it would have expanded federal funding for embryonic stem-cell research. The House and Senate had both passed the bill by wide, but not veto-proof margins, so Mr. Bush"s word is final, at least until after the mid-term elections in November. Stem cells are cells that have not yet decided what they want to be when they grow up. That is, they can become blood cells, brain cells, or pretty much any other type of cell. Their versatility makes them extremely useful for medical research. The ethical snag is that the best stem cells are harvested from human embryos, killing them. For the most ardent pro-lifers, including Mr. Bush and many of his core supporters, that is murder. Proponents of embryonic stem-cell research point out that hordes of embryos are created during fertility treatment, and the vast majority of these are either frozen indefinitely or destroyed. Is it really wrong to use them for potentially life-saving research Yes, said Mr. Bush on July 19th, flanked by some families who had "adopted" other people"s frozen embryos and used them to have children of their own. Mr. Bush"s veto does not kill stem-cell research. Scientists who spurn federal cash may do as they please. The government still pays for research on stem cells taken from adults, a process that does not kill the donor. And a decision by Mr. Bush in 2001 allows federally-funded scientists to experiment on the few dozen embryonic stem-cell "lines" that already existed then, which can be propagated in a laboratory. Nonetheless, scientists are furious with Mr. Bush. Federal funding would surely push them faster towards those elusive cures. Research based on adult stem cells may be promising, but not nearly as promising as that based on embryonic ones. There are worries that those few dozen embryonic stem-cell lines represent too narrow a gene pool, and that they cannot be endlessly extended without damaging them. Other countries, such as Britain and China, are enthusiastically experimenting on embryonic stem cells. But the world"s most innovative nation is hanging back. The expression "snag" (Line 3, Paragraph 2) most probably means ______.
