[单项选择]Passage Two

Ask why most people are right-handed, and the answer might fall along the same lines as why fish school(鱼成群地游). Two neuroscientists suggest that social pressures drive individuals to coordinate their behaviors so that everyone in the group gets an evolutionary edge. Approximately 85 percent of people prefer their right hand, which is controlled by the left hemisphere of the brain. One theorized benefit of locating a particular function in one hemisphere is that it frees the other to deal with different tasks. But that idea does not explain why. population-wide trends for handedness exist in the first place. Moreover, evidence gleaned in recent years has overturned the long-held belief that human handedness is a unique by-product of brain specialization attributable to language. A suite of studies has revealed brain lateraliz A. it was a necessary evolutionary process B. it has something to do with human right-handedness C. they need to coordinate with other fish D. their brain function is unique 查看答案 更多"Passage Two Ask why most "的相关试题: [单项选择]Passage Two Ask why most people are right-handed, and the answer might fall along the same lines as why fish school(鱼成群地游).

There is a lot of specialization, a great deal of attention to the individual, a vast amount of advanced technical equipment, and intense effort not to make mistakes because of the financial risk which doctors and hospitals must face in the courts if they handle things badly. But the Americans are in a mess. The problem is the way in which health care is organized and financed. Contrary to public belief, it is not just a free competition system. To the private system has been joined a large public system, because private care was simply not looking after the less fortunate and the elderly. But even with this huge public part of the system, which this year will eat up 84.5 billion dollars—more than 10 percent of the U.S. budget—large A. occasional mistakes by careless doctors B. a great deal of personal attention C. low charge by doctors and hospitals D. stacking nurses and bad services 查看答案 [单项选择]Passage Four Most people would agree that, although our age exceeds all previous ages in knowledge, there has been no corresponding increase in wisdom. But agreement ceases as soon as we attempt to define "wisdom" and consider means of promoting it. There are several factors that contribute to wisdom. Of these I should put first a sense of proportion: the capacity to take account of all the important factors in a problem and to attach to each its due weight. This has become more difficult than it used to be owing to the extent and complexity of the special knowledge required of various kinds of technicians. Suppose, for example, that you are engaged in research in scientific medicine. The work is difficult and is likely to absorb the whole of your mind. You have no time to consider the effect which your discoveries or inventions may have ou A. how much more wisdom we have now than before B. what wisdom is and how to develop it C. if there is a great increase of wisdom in our age D. whether wisdom can be developed or not 查看答案 [单项选择] Passage One Most people think of lions as strictly African beasts, but only because they’ve been killed off almost everywhere else. Ten thousand years ago lions spanned vast sections of the globe. Now lions hold only a small fraction of their former habitat, and Asiatic lions, a subspecies that spit from African lions perhaps 100 000 years ago, hang on to an almost impossibly small slice of their former territory. India is the proud steward of these 300 or so lions, which live primarily in a S60-square-mile sanctuary (保护区). It took me a year and a half to get a permit to explore the entire Gir Forest-and no time at all to see why these lions became symbols of royalty and greatness. A tiger will hide in the forest unseen, but a lion stands its ground, curious and unafraid-lionhearted. Though they told mc in subtle ways when I got too close, A. the present sanctuary is not large enough B. scientists want to do more research on them C. they have killed many people D. the forest is shrinking in size 查看答案 我来回答: 提交 最新试题 ●    [单选题]育龄期女性癫痫患者可选用 ●    [单选题]下列对联，最适合用于祝贺老师70岁寿辰的一联是( )。 ●    [单选题]RM80清筛车离合器补液盒中加装的是( )。[312030102] ●    [判断题]发生重大伤亡事故时，抢救工作由县级以上人民政府协调组织。 ●    [单选题]列车乘务员应该经常向旅客宣传（ ），劝阻旅客不要站在车辆连接处，不要手扶门框、风挡，不要 ●    目前我国和欧洲广泛使用的GSM（全球通）手机属于________移动通信。 网站地图 我要搜题网  版权所有  ©2023  湘ICP备18016427号   购买搜题卡查看答案 [会员特权] 开通VIP， 查看 全部题目答案 [会员特权] 享免全部广告特权 推荐91天 ¥36.8 ￥80元 31天 ¥20.8 ￥40元 365天 ¥88.8 ￥188元 请选择支付方式 微信支付 支付宝支付 点击支付即表示同意并接受了《购买须知》 立即支付 系统将自动为您注册账号 已有账号登录 找回账号密码 请使用微信扫码支付 订单号： 请不要关闭本页面，支付完成后请点击【支付完成】按钮 支付完成 取消支付 恭喜您，购买搜题卡成功 系统为您生成的账号密码如下： 账号 密码 重要提示：请拍照或截图保存账号密码！ 我要搜题网官网：https://www.woyaosouti.com 我已记住账号密码
