A: I see. Then gene therapy is to correct defective genes, isn’t it?
B: Yeah, you can say that.
A: But how?
B: Well, there are several ways, such as gene replacement to replace a nonfunctional gene with a normal one. This approach is most common. And also others like gene correction, gene augmentation, gene inactivation or immune adjustment are ways of therapy..
A: It sounds many genetic diseases then could be cured with this new technology.

B: Yeah, I like it very much. Thank you. You can’t imagine how cheap it is.
A: You got it on sale.
B: No, I got it from the internet.
A: From the internet?
B: Yeah. More and more people are now beginning to shop via the net.
A: E-commerce is thriving.
B: Well, shopping on the internet does bring much convenience.
A: But is it safe?
B: It’s better that you use retailers and services you know about, or ones that have been personally recommended to you.
A: I always worry about the security of my payment.
B: You are quite right. When you’re making payment, be wary of giving out your bank account numbers, credit card numbers or other personal information to a company you don’t know or haven’t checked out.
A: That’s very important.
B: And don’t provide information that isn’t necessary for your shopping. Many companies allow you to send your credit card details via a secure, or coded page and you should aim to buy from companies that give you this choice.
A: It may be easy to shop online, but I still prefer the old way. I feel better to touch and feel the goods personally instead of just seeing the pictures. You see, in many cases what you see is thousands of miles away from what it actually is.
