Jan Tchamani，an English teacher in Birmingham，UK，suddenly developed a serious illness and had to quit her job.At age 50，she found herself out of work and stuck at home with only her computer to keep her company.After a while，she discovered that surfing the Internet could help her feel less lonely and bored.She could listen to music，watch films，play games，and explore the world.She also joined an online group where she could talk about her problems and get support and advice from others.She realised that one of the greatest benefits of the Internet was its ability to remove the distance that usually exists between people. She was so inspired by the people she met online that she decided to start an IT club to teach older people how to use computers and the Internet.She and her friends now organise events and collect money to pay for private teachers.Many people have been helped by the club.A 59-year-old man learnt how to apply for work online and found a great job.Now that he works and can take care of himself，his daughter has time to study at university.A 61-year-old woman who was living alone has started a small online company together with two friends.She no longer feels lonely，and her company has become quite successful.

One of the greatest advantages of the Internet lies in the quick and easy access to a huge amount of information.To a certain extent，the world’s knowledge is all at our fingertips.With the click of a mouse or the touch of a button，it is possible to find out almost anything we care to know，from recipes to travel packages，from military affairs to learning resources.In the time it takes to find one book in the library，we can use a search engine to bring up millions of results.No wonder the Internet has now become the first place that the majority of people turn to for information. The Internet has also made our lives unbelievably convenient，with all sorts of goods and services provided by electronic commerce，more commonly known as e-commerce.You can have food delivered to you using food delivery apps and sites.Gone are the days of searching shop after shop for the perfect pair of boots—you can compare styles and prices quickly and easily in the comfort of your living room.Why wait hopelessly for a taxi in the cold rain？It is now simple and fast to order one with a taxi app.Sit back and relax indoors for a few warm minutes until the driver arrives.When you wish to go on holiday，you can make all your travel arrangements just in front of the computer.Forgot to carry cash？There is no need to worry—you can pay for almost everything on your smartphone. Above all else，the Internet helps us establish and maintain social ties.With all sorts of communication software，physical distance no longer gets in the way.No matter where we are，we are able to keep in contact with loved ones，find long-lost friends and discover whole new communities who share our hobbies.An instant message，a group chat，a video call，a comment on an update—there are endless ways to share our views or let someone know we care about them. However，while the Internet brings many valuable advantages，being connected has its problems.As with any great invention，we must be aware of these problems and be careful to use the Internet properly and responsibly.Only in this way can the Internet be a place of discovery，wonder and inspiration for everyone.It is truly a world without frontiers. 1.What’s the meaning of the phrase “at our fingertips” in paragraph 2?
