[单项选择]Novel approaches to babymaking seem to be coming at us so fast that we hardly have time to digest one before the next one hits test-tube babies, egg donation, surrogacy, cloning and now sex selection. And just as with earlier methods, the new sperm-separation technique announced last week has triggered plenty of ethical concern. Only a few critics have argued that tampering with nature to avoid a sex-linked genetic disease should be taboo. But plenty have expressed misgivings about using the new technology more casually, to balance families, or simply because parents prefer boys or girls. Such choices, critics say, could lead to an imbalance in the sex ratio, with drastic consequences for society.
These arguments are not very persuasive. In some developing countries where boys are more highly valued than girls, sex selection is already standard practice, accomplished by means of infanticide of amniocentesis and abortion. The new sperm-separation technique makes it easier for more

[单项选择]What kind of magic can make an 800-page novel seem too short Whatever it is, debut author Susanna Clarke is possessed by it, and her astonished readers will surely hope she never recovers. Her epic history of an alternative, magical England is so beautifully realized that not one of the many enchantments Clarke chronicles in the book could ever be as potent or as quickening as her own magnificent narrative.
It is 1806, and Gilbert Norrell is the only true magician in England. He sets out to restore the practice of magic to a nation that has not seen it for more than 300 years. But there is an odd and fateful twist to Norrell’s character: he is as scholarly and insufferably pedantic as he is gifted. In short, Norrell is the most boring and unmagical person imaginable. This is Clarke’s masterstroke, the necessary touch of ordinary candleshine in the midst of all the uncanny fairy light she dispenses.
Enter Jonathan Strange, the intuitive magician—the natural—who can improv
A. recover from the effects of her success
B. continue to produce wonderful work
C. limit her craft to Jane Austen
D. understand Strange’s magic
