We know the mosquito very well．Mosquitoes fly everywhere．They can be found almost all over the world , and there are more than 2,500 kinds of them．

       No one likes the mosquito．But the mosquito may decide that she loves you, she? Yes, she．It’s true that male mosquito doesn’t bite and only the female mosquito bites because she needs blood to lay eggs．She is always looking for things or people she wants to bite．If she likes what she finds, she bites．But if she doesn’t like your blood ,she will turn to someone else for more delicious blood．Next time a mosquito bites you, just remember you are chosen．You’re different from the others!

       If the mosquito likes you ,she lands on your body without letting you know．She bites you so quickly and quietly that you may not feel anything different．After she bites, you will have an itch （癢）on your body because she puts something from her mouth together with your blood．By the time the itching begins, she has flown away．

       And then what happens? Well ,after her delicious dinner, the mosquito feels tired．She just went to find a place to have a good rest．There, on a leaf or a wall, she begins to lay eggs, hundreds of eggs．

If you are sitting at a table with people you don’t know, it is impolite to smoke without first asking if it will disturb them. At American restaurants and coffee shops, cold water is usually served before you order. You may find the bread and the butter are free, and if you order coffee, you may get a free refill.
Most cities and towns have no rules about opening and closing time for stores and restaurants, though they usually do make rules for bars. Especially in big cities, stores may be open 24 hours a day. Serving in restaurants are often large. If you can’t finish the meal but would like to enjoy the food later, ask the waiter or the waitress for a “doggie bag”(剩菜袋). It may have a picture of a dog on it, but everybody knows you are taking the food for yourself. Tips are not usually added to check. You should leave a tip of about 15% on the table when you leave. In some restaurants, a waiter or waitress often brings your check on a plate, and you can put your money there. Then the waiter or the waitress brings you your changes.
