[单项选择]Passage Two

As one works with color in a practical or experimental way, one is impressed by two apparently unrelated facts. Color as seen is a mobile changeable thing depending to a large extent on the relationship of the color to other colors seen simultaneously. It is not fixed in its relation to the direct stimulus which creates it. On the other hand, the properties of surfaces that give rise to color do not seem to change greatly under a wide variety of illumination colors, usually (but not always) looking much the same in artificial light as in daylight. Both of these effects seem to be due in large part to the mechanism of color adaptation mentioned earlier. When the eye is fixed on a colored area, there is an immediate readjustment of the sensitivity of the eye to color in and around the area viewed. This readjustment does not immedi A. the adaptation of the eye to color B. the color of colors C. the properties of colored surfaces D. the effect of changes in color intensity 查看答案 更多"Passage Two As one works "的相关试题: [单项选择]Passage Two As one works with color in a practical or experimental way, one is impressed by two apparently unrelated facts.

Success does not necessarily mean material rewards, but recognition of some sort-preferably measurable. If a boy turn out to be a preacher(传真者) instead of a businessman, that’s all right. But the bigger his church is, the more successful he is judged to be. A good many things contributed to this accent on success. There was the Puritan(清教徒) belief in the virtue of work, both for its own sake and because the rewards it brought were regarded as signs of God’s love. There was the richness of opportunity in a land waiting to be settleD. There was the lack of a settled society with fixed ranks and classes, so that a man was certain to rise through achievement. Here was the de- termination of an immigrant to gain in the new world what bad been denied to him in the old, and on the part of his children an urge to throw off the A. success is highly valued in American society B. success surely brings material rewards C. success equals measurable recognition D. people agree on what success means 查看答案 [单项选择] Passage One Two pressing problems face the world: economic meltdown and global warming. Conveniently, a solution presents itself that apparently solves both: governments should invest heavily in green technology, thus boosting demand while transforming the energy business. This notion is gaining agreement around the world. Last month the United Nations called for a "Global Green New Deal". But it is in America that the idea is really taking off. The United States Conference of Mayors reckons that green investment should provide 2.5m jobs. The Centre for American Progress thinks $100 billion worth of spending in the area would provide 2m jobs. The new president tops both. Barack Obama proposes spending $150 billion over ten years, thus helping, he says, to create 5m jobs. There is a historical parallel to this synergy between two worthy aim A. It can provide millions of jobs with little money investment. B. It can promote demand while reforming the energy industry. C. It is helpful to the world’s peace and development. D. It is well accepted by all of the countries in the world. 查看答案 [单项选择] Passage Two One hot night last July,when our new baby wouldn’t or couhln’t sleep, I tried everything I could think of:a warm bottle, songs, gentle rocking. Nothing would settle him. Guessing that I had a long night ahead of me, I brought a portable TV into his room,figuring that watching the late movie was as good a way as any to kill of the hours till dawn. To my surprise, as soon as the TV lit up, the baby quieted right down, his little eyes focused brightly on the tube. Not to waste an opportunity for sleep, I then tiptoes out of the room,leaving him to watch the actors celebrate John Bellushi’s forty-fifth birthday. My wife and I heard none of the baby that night, and the next morning when I went into his room, I found him still watching TV himself. I found in my baby’s behavior a symbol of the new generation. My wife and I had given him some books to examine, but he merely spit upon them. When we read to hi A. They prefer reading to watching TV. B. They like watching TV alter school. C. They would rather watch TV than read books. D. They like their teachers who teach them readin 查看答案 我来回答: 提交 最新试题 ●    [判断题]保兑信用证项下,开证行不必承担第一性付款责任。( ) ●    [单选题]下列关于消防员隔热防护服的维护保养要求,错误的是( )。 ●    [单选题] 《建筑法》(草案)经全国人大八届常委会第28次会议审议,于( )正式颁布。 ●    关于甲状腺的功能检查，叙述错误的有（） ●    [单选题]特种设备安全管理机构的主要（ ）是指特种设备使用单位的实际最高管理者。 ●    [单选题]下列各种结构中，哪一种不是沉积岩的结构？ 网站地图 我要搜题网  版权所有  ©2024  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： 截图扫码使用小程序[完全免费查看答案] 前往小程序 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
