20、e. When our eyes are made uncomfortable by some small pieces of pollution, or when we are cutting onions, or when we are tired and “red-eyes” from overwork at late hours, tears form in our eyes to clean and refresh them.Tears are also a sign of strong feeling. We cry when we are sad and we cry when

21、we are happy.And tears seem to be special to human. We know that animals also have feelingfear, pleasure, lonelinessbut they do not shed tears. From this we can conclude that tears are closely related to the feeling and biological （生物的）make-up of the people.Biologically speaking, tears are actually

22、drops of a slightly salty fluid, produced by a gland（腺）in the body.

23、 to the emotional benefits, the shedding of tears has a specific biological function as well. Through tears, we can eliminate from our body certain chemicals（化學物質(zhì)） which build up in response to stress and create a chemical imbalance in the body.

28、n Times Square in New York City. To what does Gordon owe his cars very long life?“Volvos are very strong cars,” he said. “Also, I drive carefully.
