阅读短文，从题中所给的A, B, C, D四个选项中选出最佳答案。       A kind of little cars may some day take the place of today"s ones. If everyone drives such cars in the future,
there will be less pollution in the air. There will also be more space for parking cars in cities, and the streets will
be less crowded. Three such cars can fit in the space now needed for one car of the usual size.
       The little cars will cost much less to own and to drive. Driving will be safer, too, as these little cars can go
only 65 kilometers an hour.
       The cars of the future will be fine for getting around a city, but they will not be useful for long trips. Little
cars will go 450 kilometers before needing to stop for more gasoline (汽油).
       If big cars are still used along with the small ones, two sets of roads will be needed in the future. Some
roads will be used for the big, fast cars and other roads will be needed for the slower small ones. 1. There is much pollution in the air today because ____. [     ]

阅读理解。    You can find out many things about a tree by studying its rings.
     Each year, from top to bottom, a tree grows a new layer (层) of wood around itself. If you cut across a
tree trunk or branches, you would see that these layers of wood look like rings. By counting tree rings, you
can tell how old the tree is. If you count ten rings, for example, the tree is ten years old.
    Looking at the picture shown above, you can see that each tree ring has a dark part and a light part. The
light part wood grows in the spring, the dark part wood in winter. Look also, that some rings in the picture
are wide and others are narrow (窄). Trees grow aide rings during the years when they get a lot of water and
sun-light. By examining tree rings, you can tell what the weather may was like many years ago.
   Giant sequoia (红杉) trees, such as the one in the photo above, grow in north-western California. Some of
these sequoias have more than 3000 tree rings. Can you guess how old such a tree would be? 1. According to the story, a tree ring is a ______.[     ]

阅读理解。    One of my favourite things to do is hiking in mountains. Because nobody likes the idea of getting lost, I
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.

1. The writer prepares before every trip because he doesn"t ______. [ ]
A. like the old map or compass
B. know how to use the GPS
C. want to get lost in mountains
D. want to get into the mountains alone 2. The two teams ______. A. had the same navigation tool
B. went along the same trail
C. had the same problem
D. finished the whole hike at the same time 3. In the end, the writer found out ______. [ ]
A. the map and the compass were too old navigation tools to use any more
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
