During the day we work and play; at night we sleep. Our bodies rest while we sleep. In the morning we
are ready to work and play again. While we are asleep our bodies grow most. Children who are tired usually
need more sleep. We can get our lessons better and we feel better too, when we have had plenty of rest.
Boys and girls who are eight or nine years old need ten hours of sleep every night. Our bodies need plenty
of air when we sleep. If we do not get enough fresh (新鲜的) air we"ll feel tired when we wake up. While
in bed we must not cover our heads. If we do, our lungs (肺) will not get enough fresh air. If we open our
windows at night we can have plenty of fresh air. Cool air is better than warm air. Boys and girls who want
to grow and be strong must get plenty of sleep.

always prepare before every trip. But what"s the best navigation tool, a Global Positioning System (GPS) or
a good old map and compass? Five of my friends and I hiked through the mountains on a trail I marked. One
team of three carried a GPS, and the other team used a map and compass.
It took the GPS team 3 hours and 11 minutes to get through the whole hike, however, it took the map and
compass team only 2 hours and 49 minutes. The biggest problem the GPS team met was that they lost the
satellite signal (卫星信号) in some places. With no map or compass, they had to walk around until they were
in a place where the signal was good. The map and compass team was able to spot (认出) different landmarks,
compare them to their maps and then use the compass to point them in the right direction.
When I head out on my future hikes, I"m bringing a map, a compass and a GPS to show me the way.
B. know how to use the GPS
C. want to get lost in mountains
D. want to get into the mountains alone
B. went along the same trail
C. had the same problem
D. finished the whole hike at the same time
B. it wasn"t necessary to bring a map and a compass together with a GPS
C. the GPS had some disadvantages in hiking in mountains
Dreams take up about one quarter of our sleeping time. People have several dreams each night. Dreams
are like short films.They are usually in colour. Some dreams are like old films.They come to us over and over
again. That may be because the dreamer is worrying about something. Dreaming may be a way of trying to find
an answer.
Some people get new ideas about their work from dreams. They may have been thinking about their work
all day. These thoughts can be carried over into dreams.
Sometimes we wake up with a good feeling from a dream. But often we can"t remember the dream.
Dreams can disappear quickly from memory.

| Trees are useful to men in three important ways: They provide them with wood and other products (产品), they give them shade (树荫), and they help to prevent drought and floods. Unfortunately, in many parts of the world, men have not realized that the third of these services is the most important. In their eagerness (渴望) to make money from trees, some people have cut trees down in large numbers, only to find that without them they have lost the best friends they had. And besides (此外), they are usually too careless to plant and look after new trees, so the forests slowly disappear. This doesn"t only mean that men will have fewer trees. The results are even more serious: where there are trees, their roots (根) break up soil-allowing the rain to sink in and also bind (固定) the soil, thus (因而) preventing it from being washed away easily, but where there are no trees, the rain falls carrying away the rich top-soil. When all the top-soil is gone, nothing remains (剩下) but worthless desert. | |||
