一、阅读理解
When you're packing for an adventure, what's the most important thing you'll need? If you don't want to get lost, you'll need a map! Or better yet, a GPS. What about animals? How do they know where they're going?
While humans depend on technology to travel, some animals have something far more advanced. Some American scientists found that Chinook salmon (国王鲑) have a “built-in GPS” of the Earth's magnetic field (磁场). This means as soon as they are born they are able to direct themselves in the ocean (海洋). It acts like a big map inside their brain.
Scientists placed some baby salmon into a big swimming pool. To simulate the Earth's magnetic field, they put magnetic coils (线圈) all around the pool. Then, by changing the direction of the coils, the salmon began to change their own direction. They started to face the direction of their ocean feeding area. This is a safe place in the ocean where salmon can find food to eat. When the scientists changed the coils to the opposite side, the salmon also turned in the opposite direction. Just by using their “built-in GPS”, the salmon were able to find out the direction of their feeding area.
How did Chinook salmon get their “built-in GPS”? The scientists believe that their navigation (导航) skills came through evolution (进化). The fish that were able to reach the feeding area lived longer.

This is a milk advertisement. In it, we can see ______ ______ ______ ______

答案：
white clouds, the blue sky, the yellow sun, green
grass and mountains. White represents peace. It is also the colour of milk. The white clouds look just 
like flowing milk. Blue makes people feel calm and comfortable. The sun is shining brightly. And the 
yellow reminds people of a warm sunny day. Green is the colour of health and energy. It represents new 
life. On the green grass there are many black and white cows. They are strong and healthy. I think the 
advertisement is very successful. The colours in the advertisement are all bright. When we see the 
advertisement, we feel very happy and energetic. We believe the milk must be good for our health.
