When you’re packing for an adventure, what’s the most important thing you’ll need? 1. Or better yet, a GPS. What about other animals, how do they know where they’re going?
While humans depend on technology to travel, some animals have something far more advanced. Researchers, mainly from Oregon State University, US, found that Chinook salmon (鲑鱼) have a “built-in GPS” of the Earth’s magnetic field. 2.It acts like a big map inside their brain.
Scientists placed some baby salmon into a big swimming pool. To simulate (模拟) 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 in the direction of their ocean feeding area. 3.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 figure out the direction of their feeding area.
4.The scientists believe that their navigation skills came through evolution. The fish that were able to reach the feeding area lived longer. 5.So if you’re ever lost and in need of some help, maybe you should ask a salmon to point you in the right direction!
A. How did Chinook salmon get their “built-in GPS”?
B. If you don’t want to get lost, you’ll need a map!
C. This is a safe place in the ocean where salmon can find food to eat.
D. Then they could pass on their navigation skills to their babies.
E. However, the magnetic field is likely not the only tool salmon use to navigate.
F. It turns out young salmon don’t just learn quickly, they don’t need to learn at all.
G. This means as soon as they are born they are able to direct themselves in the ocean.

For teenagers, it's great fun to explore new places and it feels like an adventure, even when you know you're not the first to have been there. But to make sure not to get lost or waste time going round in circles, the following tips may be helpful.
◆Do the map reading if you're being driven somewhere. It'll be easier if you keep the map following the direction you are traveling in. Keep looking ahead so that you can give the driver lots of warning before having to make a turn, or you'll have to move to the back seat.
◆Get a group of friends together and go exploring. You'll need a good map, a compass, a raincoat, a cell phone to call for help in case you get lost, and a bit of spare cash for emergencies. Tell someone where you're going before you set out and let them know what time you expect to be back. The purpose of the activity is in not getting lost, not in seeing how fast you can go, so always stick together, waiting for slower friends to catch up.
◆See if your school or a club organizes orienteering(越野识途比赛) activities, in which you need a map and a compass to find your way. This can be done as a sport, with teams trying to find the way from A to B(and B to C, etc. ) in the fastest time, or simply as a spare-time activity. It enables you to be familiar with the use of maps and compass and gain some special skills. In some way, it’s not only good fun, but also a great way to keep fit.
1.When you sit beside the driver, you’d better ________.
A.look ahead to see where there is a gas station
B.move to the back seat if feeling uncomfortable
C.keep looking at the map to find another place to go to
D.direct the driver when necessary
2.In the exploration, why do you need to wait for the slower friends?
A.To share the fun with him/her in exploration.
B.To tell him/her what’s going on with group members.
C.To avoid yourself or your friends getting lost.
D.To show them how fast you can go.
3.What does the whole passage talk about?
A.The fun of exploration.
B.What to bring for exploration.
C.How to prevent people getting lost in exploration.
D.The way to use a map in exploration.
