Unit 1 Food matters
Grammar and usage
As a real foodie, I enjoy all kinds of foods. My dream is to try different restaurants and taste various foods.
Yesterday I invited some friends to try a great new restaurant for dinner.
We arrived at the restaurant, only to see a huge line of people waiting to get into the restaurant.
Nothing can stop our determination to have a try. We decided to wait outside.
After an hour of waiting, we were invited to go into the restaurant and take the order.
The dishes are extremely delicious. It is worthwhile to have such a long wait.
