In Canada and the United States, people enjoy entertaining(请客) at home. They often invite friends over for a meal, a party or just for coffee and conversation.

Here are the kinds of things people say when they invite someone to their homes:

"Would you like to come over for dinner this Saturday night?" "Hey, we're having a party on Friday. Can you come?"

To reply to an invitation, either say thank you and accept, or say you're sorry and give an excuse. "Thanks, I’d love to. What time would you like me to come?" or "Oh, sorry. I've tickets for a movie. "

Sometimes, however, people use expressions that sound like invitations but which are not real invitations. For example; "Please come over for a drink sometime. " "Why not get together for a party sometime?" " Why don't you come over and see us sometime soon?"

They are really just polite ways of ending a conversation. They are not real invitations because they don't mention a certain time or date. They just show that the person is trying to be friendly. To reply to expressions like these, people just say "Sure, that would be great!" or "OK. Yes, thanks. "

So next time when you hear what sounds like an invitation, listen carefully. Is it a real invitation or is the person just being friendly?

If you think GM food sounds far away from you, you are totally wrong. In fact, you may eat GM food every day. Four of every five people in the world are eating GM food, according to the Ministry of Agriculture.

According to Xinhua News Agency, in China, the only GM plants that are grown for sale are cotton and papaya. Also, China buys some GM plants from other countries, such as soybeans and corn. The GM plants are used to make other products.

A reporter once said, “In China, more than half of cooking oil is soybean oil. And 90 percent of that oil is made from GM soybeans.” So it’s possible that we eat GM food every day!

Scientists have changed GM plants’ DNA in a laboratory. Scientists usually do this to protect plants against bugs and diseases and have more harvests. Many people think it’s against nature. Also, they worry that eating such food might be bad for their health.

Is GM food safe? There’s no agreement. Some people say that GM food causes tumors. But there are no long-term safety studies about GM food. If you want to stay away from GM food, you can start by checking the cooking oil in your home.
