单选题 Questions9-11 are based on the passage you have just heard.

单选题Women are moody. By evolutionary design, we are hard-wired to be sensitive to our environments, empathic to our children"s needs and intuitive of our partners" intentions. This is basic to our survival and that of our offspring. Some research suggests that women are often better at articulating their feelings than men because as the female brain develops, more capacity is reserved for language, memory, hearing and observing emotions in others. These are observations rooted in biology, not intended to mesh with any kind of pro- or anti-feminist ideology. But they do have social implications. Women"s emotionality is a sign of health, not disease; it is a source of power. But we are under constant pressure to restrain our emotional lives. We have been taught to apologize for our tears, to suppress our anger and to fear being called hysterical. The pharmaceutical industry plays on that fear, targeting women in a barrage of advertising on daytime talk shows and in magazines. More Americans are on psychiatric medications than ever before, and in my experience they are staying on them far longer than was ever intended. Sales of an tidepressants and antianxiety meds have been booming in the past two decades, and they"ve recently been outpaced by an antipsychotic, Abilify, that is the No. 1 seller among all drugs in the United States, not just psychiatric ones. At least one in four women in America now takes a psychiatric medication, compared with one in seven men. Women are nearly twice as likely to receive a diagnosis of depression or anxiety disorder than men are. For many women, these drugs greatly improve their lives. But for others they aren"t necessary. The increase in prescriptions for psychiatric medications, often by doctors in other specialties, is creating a new normal, encouraging more women to seek chemical assistance. Whether a woman needs these drugs should be a medical decision, not a response to peer pressure and consumerism. Obviously, there are situations where psychiatric medications are called for. The problem is too many genuinely ill people remain untreated, mostly because of socioeconomic factors. People who don"t really need these drugs are trying to medicate a normal reaction to an unnatural set of stressors: lives without nearly enough sleep, sunshine, nutrients, movement and eye contact, which is crucial to us as social primates.
