[单项选择]Passage Five

When you watch a football game on a Saturday afternoon, you feel secure in your knowledge of what will happen when a player boots the ball. It first goes up and then it comes down. That’s how it is, was, and will be--unless.... if the kicker someday should kick the ball such that at the instant it left his toe it were travelling upward at a rate of 11.2 kilometers per second (25 000 mhr). We would find that we would not have to worry about a punt return, because the ball simply would not come down. This particular speed is the escape velocity of an object from the earth. At this speed, any object, large or small, will escape from the earth to soar forever upward until captured by the gravitational attraction of some other planet or heavenly body. At first thought it might seem that a heavy object might require a greater initial spe A. reach other planets B. make a goal C. escape from the earth D. go upwards 查看答案 更多"Passage Five When you wat"的相关试题: [单项选择]Passage Five When you watch a football game on a Saturday afternoon, you feel secure in your knowledge of what will happen when a player boots the ball.

Once you get him out of the water, if he isn’t breathing, you have four minutes before his brain is completely damaged. Support his neck, tilt his chin upwards. This stops the tongue blocking the air way in the throat and is sometimes enough to get him breathing again. If that doesn’t work, start mouth-to-mouth breathing. Press his nostrils (鼻孔) together with your fingers. Open your mouth wide and take a deep breath. Blow into his lungs until his chest rises, and then remove your mouth and watch his chest fall. Repeat twelve times a minute, keep going until professional help arrives. To bring a child back to life, keep your lips around its mouth and nose and gently blow into its mouth. Give the first four breaths as quickly as possible to fill the blood with oxygen.

Greeks, others of the Eastern Mediterranean, and many of those from South America normally stand close together when they talk, often moving their faces even closer as they warm up in a conversation. North Americans find this awkward and often back away a few inches. Studies have found that they tend to feel most comfortable at about 21 inches apart. In much of Asia and Africa, there is even more space between two speakers in conversation. This greater space subtly lends an air of dignity and respect. This matter of space is nearly always unconscious, but it is interesting to observe. This difference applies also to the closene A. are similar to South Americans B. stand farthest apart C. feel ill at ease when too close D. move nearer during conversations 查看答案 我来回答: 提交 最新试题 ●    [单选题]硬横跨的安装高度应符合设计要求，允许误差不超过（ ）mm。 ●    [判断题]营门警卫人员，应当检查出入营门人员的证件和队容风纪。( ) ●    [多选题]作战原则主要有( )。 ●    [单选题]高速铁路线路雨量警戒规定分为两种执行模式：（ ）模式和（ ）模式。 ●    [单选题]互联网时代的版权保护需要更为灵活包容的政策措施，在保障原创者、版权人利益的同时，也为互联网 ●    [单选题]《供电营业规则》规定,( )及以上公用高压线路供电的,以用户厂界外或用户变电站外第一基电 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
