铃声响了，教师走向钢琴，说："今天我给大家带来一节非常有意思的课（激起学习兴趣），用上你们的耳朵和眼睛（提出活动要求），把你们的观察告诉我（学生更加精神集中，猜测即将发生的事情）。"琴声响了，数名听课教师搬着椅子，随着音乐的速度与节奏，出其不意、精神抖擞、步伐整齐、动作划一地走入教室。学生被震撼了、惊呆了，数秒钟之后，掌声雷动，跺脚声咚咚，仿佛整个教室都处于行进中。教师只问了几个问题，"你们看到了什么？听到了什么？观察到了什么？每个问题背后再多问一个为什么。"教室内顿时气氛热烈：按捺不住地举手发言、前后左右地交换意见、会心满意地相互微笑、积极主动地思考发现。热烈讨论之后，教师归拢大家的意见，板书"行进中的歌"。
请对这位老师的这一教学行为进行评价。
"Copper" and "bobby" are two of several nicknames that the English policeman has. And "peeler" was the early nickname for the policeman, but this one has died out. Of course, among the criminal part of the community where the police are given more derogatory (贬损的) nicknames which originated in America, such as "fuzz" or "pig".
Visitors to England seem, nearly always to be very impressed by the English police. They are usually very friendly and have helpful sort of character. In London, the policemen spend so much of their time directing visitors about the city that one wonders how they ever find time to do anything else!

The meanings of "science" and "technology" have changed significantly from one generation to another. More similarities than differences, however, can be found between the terms. 46) Both science and technology imply a thinking process, both are concerned with causal relationships in the material world, and both employ an experimental methodology that results in empirical demonstrations that can be verified by repetition. 47) Science, at least in theory, is less concerned with the practicality of its results and more concerned with the development of general laws, but in practice science and technology are inextricably involved with each other. The varying interplay of the two can be observed in the historical development of such practitioners as chemists, engineers, physicists, astronomers, carpenters, potters, and many other specialists. Differing educational requirements, social status, vocabulary, methodology, and types of rewards, as well as
观看视频"故宫"的片段，回答问题。
"紫禁城"这个名字和中国古代哲学和天文学有关。中国人认为"天人感应"和"天人合一"。因此故宫的结构是模仿传说中的"天宫"构造的。古代天文学把恒星分为三垣，周围环绕着28宿，其中紫微垣（北极星）正处中天，是所有星宿的中心。紫禁城之紫，就是"紫微正中"之紫，意为皇宫也是人间的"正中"。"禁"则指皇室所居，尊严无比，严禁侵扰。
故宫房屋有9999间，每个门上的铜门钉也是横竖9颗。这种奇特的数字现象和古代中国人对数字的认识有关。古代人认为"9"字是数字中最大的，皇帝是人间最大的，所以必须用对应的"9"。"9"的谐音为"久"，意为"永久"，所以又寓意为江山天长地久，永不变色。故宫里建筑的名称，都有"仁""和""中""安"等字，如太和殿等，这些字所代表的意义是中国儒家思想的核心，即"中正""仁和"，突出了传统的儒家理念。
皇帝、皇后居住的乾清宫、交泰殿、坤宁宫的名字也和儒家经典《易经》有关。《周易》说，"乾"象征"天"，代表"男"；"坤"象征"地"，代表"女"；中间的"泰"意为"平安、畅通"，整个意思即为"天地交泰"，暗示帝后关系和谐，再加上"清正""宁静"，把一个皇宫生活想象得异常美丽。
故宫里的颜色也有深奥的寓意。故宫多用黄色琉璃瓦，室内的颜色也多为黄色，乾清宫的布置尤其突出。这种用法来源于古代经典《尚书》中的五行说。古人认为世界由"金、木、水、火、土"五行构成，五种元素相生相克，世界因此变化不定。"黄色"代表"土"
"Go for it !"
The expression "Go for it!" is a way of encouraging someone to try something.
"Go for it!" means you should not worry about failure or be too careful. You should take a chance, be brave, and act firmly.
"Go for it !" gets its name from football. Not football as it is played in most countries such as England, Egypt or Japan, but the kind of football played in the United States and Canada.
One of the most exciting times in football comes when a team has failed, after three attempts, to move the ball forward ten yards. The team must make a critical decision.
The conservative (保守) choice is to kick the ball and accept temporary defeat in order to gain a good position for your team the next time it gets the ball. The more exciting choice, however, is to try a fourth and final time to gain the remaining yards needed.
People present are certain to shout their advice. Some will shout: &q
A. English football
B. Egyptian football
C. Japanese football
D. American football
The words "gymnastics" and "gym" come from the Greek language, for it was in Greece that Olympic competitions started. There are also records of gymnastics being performed in China and some other Asian countries. Modem gymnastics began in the 19th century. In 1811 an outdoor gymnastics center for men was opened in Berlin where they could do body-building and exercises on a high bar and other pieces of equipment. At the same time, gymnastics, without equipment, was developed in Sweden as a keep-fit program for schools.
Dance is an important part of training as it prepares you for the types of movements required in gymnastics. One of the aims is to make the body stronger for jumps and turns and for movements of balance. It also helps your body bend forwards, backwards and sideways, and improves the way you hold your body. In competitions women perform some of their exercises to music, so dance, gymnastics and music are all connected.
