There is a popular belief that goldfish only have a three﹣second memory．But a 15﹣year﹣old schoolboy from Adelaide has just finished an experiment（实验） to tell us that it is not true．He shows everybody that the goldfish is smarter than we think．
"I don't believe that they had a three﹣second memory because animals need their memory，so they build up over time a knowledge of where the food is，"said Roy Stokes，a student at the Australian Science and Mathematics School．
He did the experiment in small tank（鱼缸） of goldfish．"I decided to get a bit of red Logo and just feed them next to that．Every day I'd put it in and spread food around it．"He said．
"At first they were a bit scared of it，but by the end of the three weeks，they were actually almost coming before I put the food in．"
After leaving the fish alone for a week，Rory placed the red Logo block in the tank again．
"They remembered perfectly well，"he said．
"They actually had a time faster than the average of the three feeds before I left．"
The goldfish showed that not only could they store information，they also had the ability to get it back as a later date．
Culum Brown，a research fellow at Sydney's Macquarie University，has studied fish behavior for more than ten years．
He says his studies of Australian native fish show fish were intelligent creatures that know how to avoid enemies and catch food like any other animal．
"The thing that I really liked about Rory's experiment is he not only got that classical conditioning going but the fact that he could get them next just to that specific coloured market．I thought it was really good．"He said．

After my husband died, my world crashed around me. My six children were ten, nine, eight, six, three and 18 months, and I was overwhelmed(不知所措的) with the responsibilities of earning a living, caring for the children and simply keeping my head above water.
I was lucky to find a wonderful housekeeper to care for the children during the week, but from Friday nights to Monday mornings, the children and I were alone, and frankly(坦诚地) I was uneasy. Every unusual noise or any late-night phone call filled me with fear. I felt really alone.
One Friday evening I came home from work to find a big beautiful German shepherd(牧羊犬) on our doorstep. It was obvious he wanted to make the house his home. The children took an instant liking to “German” and asked me to let him in. I agreed to let him sleep in the basement(地下室) until the next day. That night I slept peacefully for the first time in many weeks.
The following morning we made phone calls and checked lost-and-found ads for German’s owner, but with no results. Saturday night he was still with us.
On Sunday I had planned to take the children on a picnic. Since I thought it best to leave German behind in case(以免) his owner came by, we drove off without him. When we stopped to get gas at a local station, we were amazed to see German racing to the gas station after us. He stayed again Sunday night.
Monday morning I let him out for a run while the children got ready for school. He didn’t come back. We thought we’d never see him again. On Friday evening, German was back again. We took him in, and again he stayed until Monday morning, when our housekeeper arrived. It went like this for almost 10 months. We looked forward to his coming. Each Monday morning he left home.
Each week, between German's visits, I grew a little braver, but every weekend I enjoyed being with him . Then one Monday morning we patted his head and let him out for what turned out to be the last time. He never came back. We never saw or heard from German again. I think of him often. He came when I needed him the most and stayed until I was strong enough to go on alone. I believe German was sent because he was needed, and because no matter how abandoned(被放弃的) and alone we feel, somehow, somewhere, someone knows and cares. We are never really alone. What does the underlined part “keeping my head above water” in the first paragraph mean?
| A．trying to keep calm in public |
| B．trying to get attention from other men |

Taking away a city’s rubbish is a big job. Every day trucks come into a city to collect it. Most rubbish is made up of things we can’t eat or use. If we kept these things we would soon have a mountain of rubbish.
In some cities the rubbish is collected and taken outside of the city to a dump(垃圾站). Often the city dump is placed where the ground is low or there is a big hole. The kitchen rubbish is broken into small pieces and sent into the sewage system. The sewage system takes away the used water from toilets, bathtubs(澡盆) and other places.
To keep mice and flies away, some earth is used to cover the newly dumped rubbish. Later, grass may be planted on the rubbish-filled land. Finally, a house or a school may be built there, and then you’d never know that this had once been an old rubbish dump.
In other cities the rubbish is burnt in special places. The fire burns everything but the metal. Sometimes the metal can be used again in factories where things are made of metal. The food parts of rubbish are put in special piles where they slowly change into something called humus(腐殖土), which looks like black earth. It is rich with kinds of things that feed plants and help make them grow.You can most probably read the passage in _______.
| A．a history book | B．a TV guide |
| C．a science book | D．a telephone book |

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. 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 |
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 |
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 bad points in hiking in mountains |
| D．he wouldn’t use a GPS any more |
