题目内容
4.In 1819,a Danish scientist named Hans Christian Oersted discovered the close relationship between electricity and magnetism through an experiment.His discovery led to the study of electromagnetism(电磁).Try Oersted's experiment yourself!Materials you will need:a small non-metal bowl,a needle(针),a magnet,two wires(电线),a power pack(电源组).___________:1.Touch the needle 50times from the center to one end with the magnet.Place it in a bowl of water.2.Watch the movement of the needle when you put the magnet near it.3.Place the wire over the top of the bowl.4.Link one end of the wire to the switch.5.Link both ends of the wire to the ends of the power pack.6.Close the switch.
Now you've done the experiment that Oersted did and have known that there's a magnetic field around the wire when the electric current(电流)is flowing.When the current flows,the needle turns aside.
This experiment is one of the most important in the use of electric power,and led to the discovery of electromagnetism and the development of the electric engine.
76.What should you watch during the experiment?
The movement of the needle.
77.What's the passage mainly about?(Please answer within 8words)
How to do Oersted's experiment.
78.Fill in the blank with appropriate words.(Please answer within 6words.)
Steps to take
79.Which sentence in the passage is the closest in meaning to the following one?The ends of the wire should be connected with the ends of the power pack.
Link both ends of the wire to the ends of the power pack.
80.Translate the underlined sentence in Paragraph 4into Chinese.
这个实验是电能使用最重要的实验之一,它导致了电磁的发现推动了电动机的发展..
分析 本文主要讲述了发现电和磁场的重要的实验,以及可以自己动手体验该实验.
解答 76.The movement of the needle.细节理解题.根据文章内容Watch the movement of the needle when you put the magnet near it 当你把针靠近磁石时,会观察到针的移动.
77.How to do Oersted's experiment.主旨大意题.根据文章内容先是介绍了这个实验.以及1.Touch the needle 50times from the center to one end with the magnet.Place it in a bowl of water.2.Watch the movement of the needle when you put the magnet near it…具体的操作步骤,由此可知本文主要讲述了如何做这个实验.
78.Steps to take 推理判断题.Try Oersted's experiment yourself!Materials you will need:a small non-metal bowl,a needle(针),a magnet,two wires(电线),a power pack(电源组).___________:1.Touch the needle 50times from the center to one end with the magnet.Place it in a bowl of water.2.Watch the movement of the needle when you put the magnet near it.前文说到让自己动手做实验,后面提到所需物品以及操作步骤,由此推断合适的内容为Steps to take.
79.Link both ends of the wire to the ends of the power pack.细节理解题.原句为The ends of the wire should be connected with the ends of the power pack.电线的一端应和电力的一端相连接,结合原文,同义句为Link both ends of the wire to the ends of the power pack.
80.这个实验是电能使用最重要的实验之一,它导致了电磁的发现推动了电动机的发展.翻译题,句子为This experiment is one of the most important in the use of electric power,and led to the discovery of electromagnetism and the development of the electric engine.翻译过程中注意一些固定搭配的译法:one of+可数名词复数…之一 lead to 导致 the developmeng of..的发展
点评 做该类阅读表达时要求考生对文章通读一遍,做题时结合原文和题目有针对性的找出相关语句进行仔细分析,推理判断题也是要在抓住关键句子的基础上合理的分析才能得出正确答案,切忌胡乱猜测,一定要做到有理有据.
Write NO MORE THAN THREE WORDS for each answer.
Internet shopping is a new way of shopping.You can shop for just about anything from your armchair.All you need is a computer which is linked to the Internet.
People can shop for different kinds of products on the Internet.Physical products(产品) include items such as books,CDs,clothes and foods.You can also buy information products such as on-line news or magazine stories,or you can download computer software through the Internet.Services such as booking airline tickets,reserving(预订) hotels or renting cars are also available on the Internet.You can also go shopping on the Internet for entertainment services such as on-line games or e-mail"chats".
To find something on the Internet,people often use powerful computer tools called"search engines".You can search for a type of product,such as sports shoes,or a brand name,such as Nike.The search engine will give you a list of websites where you can find these products.These websites may be specialist shops such as a Nike shop,or they may be general stores,called malls,which sell a variety of goods.
The main disadvantage of Internet shopping is that you can not actually see the products you are buying or check their quality.Also,many people enjoy shopping in the city and miss the opportunity to talk to friends.Some people are worried about paying for goods using credit cards(信用卡),so Internet companies are now finding ways to make on-line payment safe.
Internet shopping is sure to become more and more popular in the years ahead.It promises to change the way we buy all kinds of things----from tonight's dinner to a new car.
