请看一下我连接词有没有放错! A robot is a mechanical device that can perform boring, dangerous, and difficult tasks. First of all, robots can perform repetitive tasks without becoming tired or bored, so they are used in automobile factories to weld and paint. Second, robots can also function in hostile environments, and they are useful for exploring the ocean bottom as well as deep outer space. Finally, robots can perform tasks requiring pinpoint accuracy. In the operating room, robotic equipment can assist the surgeon; for instance, a robot can kill a brain tumor, beside it can operate on a fetus with great precision. The field of artificial intelligence is giving robots a limited ability to think and to make decisions; however, robots cannot think conceptually and function independently. Humans have to program them; otherwise, they are useless. Therefore, humans should not worry that robots will take over the world-at least not yet. 这里帮我看标点符号对不对! 1.Information and communication technology is reaching out to help people in the poorest countries improve their lives; for example, fishermen on the Bay of Bengal can now receive online weather reports that tell them when it is safe to go out. 2.Furthermore, when the fishermen bring in a boatload of fish, they can find out the current market prices for their fish, which will help them bargain with the middlemen to whom they sell their catch. 3.The cost of the cheapest computer is at least $200, and since this is more than an individual, fishermen can afford several fishing villages together; can pool their money and buy one to share. 4.The worldwide reach of the Internet is also providing employment opportunities in developing countries, and as greater numbers of people learn the technology these opportunities will expand. 5.When you call your U.S. bank, you may find yourself speaking to a customer service representative who is sitting in the Philippines or Puerto Rico; and when you need technical support for your home computer, you will probably get help from a programmer in New Delhi. 这里是要把after,although,because,when加进去 这样放对吗? Russian women started to gain equality earlier than women in the United States. The concept of equal rights and responsibilities for women was part of communist philosophy, so Russians of both sexes had equal access to education and jobs from the beginning of the Soviet Union. The 1937 Soviet constitution declared that women and men had equal rights and responsibilities, but women in the United States do not have legal equality even today. Although an amendment to the U.S. Constitution giving women equal rights has never been approved. Because before World War Ⅱ, few U.S. women worked outside the home. When millions of men left to become soldiers during the war, and women took over their jobs. Suddenly, women discovered that they could do anything, after the men returned home, and women began to demand the equality that they had earned. 感谢喔! --
