It's 21:00 in Beijing now. Let's look at what the four students are doing.

    In traditional Chinese medicine, food is divided (划分) into two types; hot and cold. Both kinds of food affect (影响) your body {#blank#}1{#/blank#} different ways, So, having 57. {#blank#}2{#/blank#} balanced diet is safe and {#blank#}3{#/blank#} (health) for your body.

    Some examples of hot food {#blank#}4{#/blank#} (be) berries, mutton, and ginger (生姜) . If you eat too much of them, {#blank#}5{#/blank#} (certainly) things might happen to your body. You may start to sweat a lot and feel pain in your back, or even grow gray hair! If these things happen to you, you should avoid (避免) spicy food, coffee, or sugar.

    On  {#blank#}6{#/blank#} other hand, too much cold food like tomatoes and potatoes can also cause problems. It may make your hands and  {#blank#}7{#/blank#} (foot) cold. It also makes your body temperature lower.

    Besides what we eat, {#blank#}8{#/blank#} we eat is also important. You should always sit down and chew (咀嚼) carefully. Don't make {#blank#}9{#/blank#} (you) busy with other things, such as watching TV or {#blank#}10{#/blank#} (read) a newspaper. Finally, it's best to eat three meals a day at regular times.

There is an English saying:" Laughter is the best medicine." Until {#blank#}1{#/blank#}, few people took the saying seriously. Now however, doctors have begun to look into laughter and the effects it has on the human body. They find that it {#blank#}2{#/blank#} people's blood pressure, the heart beating and breathing. It {#blank#}3{#/blank#} works the stomach and even the feet. So laughter exercises the body and improves people's health.

As a result of these discoveries, some doctors in the United States now hold laughter clinics; in which they help to improve their patients' condition {#blank#}4{#/blank#} encouraging them to laugh. They have found that even if their patients do not really feel like {#blank#}5{#/blank#}, making them smile is enough to produce beneficial effects similar to those caused by laughter.
