(单词翻译:单击)
Most of them travel 40,000 miles to a satellite and then back to earth. Ten years ago, a satellite was capable of receiving and transmitting more than 33,000 telephone conversations simultaneously. Now a single satellite is able to transmit over l00,000 conversations as well as several television channels -- all at the same time.
Telecommunication can make information from around the world available to use quickly and easily, but some people worry that this may be a risk to our privacy. If personal information is stored in computers, then it may be easily transmitted via satellite to anyone who can pay for the service.
Another worry is that telecommunication systems may isolate people from each other. When people are able to shop from their homes, do their banking without leaving the house, watch any movie they want on their television, as well as get any information they need, then there will not be as much contact between people.
It is important to realize that the same technology that helps us may also harm us. We can prevent this from happening by carefully controlling the new technology. As one telecommunication expert says, We must remember that technology alone is not the answer...It is (the intelligent application of technology) that will lead us to success.
It+be+强调部分+that(who)分句

It was in Beijing that they met each other for the first time.
