Once upon a time, there was no television. That wasn't because no one had tried to invent it. Scientists had worked on the idea starting in the late 1800's. Many years passed before television worked well.

　　In the 1940's, television caught on. It was a hit from the beginning. Soon the movie business, the restaurant business, and even the jukebox (大型唱机) business went down. Americans stayed home to watch television. How much watching do people do? The graph(图表) below can help you decide.

　　This graph is called a pictograph. It shows the average number of hours a day that people have watched television in different years.

　　A pictograph uses pictures, or symbols, to show information. In the graph at the left, the symbol is a clock. Find the key at the bottom. The key tells you that each clock on the graph equals one hour of television watching. Half a clock equals one-half hour of watching.

　　To read the graph, count the number of clocks in the row for each year. A row runs across, from side to side. Use the graph to answer the questions below.

1．The average number of hours spent watching TV in 1960 was ________ .

[　　]

Reading comprehension(阅读理解)

　　The world is full of variety. Trees, grasses, and leafy plants cover the earth. Above, the sun shines on the earth as it turns in the ever-changing sky. This is the familiar world that we see around us every day. It is the world that story-tellers and poets write about.

　　This world is also the world of chemistry. In this world, one form of matter changes endlessly into another. We cannot always see it happening with the naked eyes(肉眼). Yet it is something which is taking place all the time. The millions of forms, alive or not, which exist on the earth are all made up of about one hundred basic chemical elements. The same elements are found everywhere. Only the combinations and the quantities differ. This may seem astonishing, but it is true. It is true not only of the earth but also of the whole universe.
