It’s a popular belief that a fish’s memory lasts for only seven seconds. It may seem sad to think that they don’t remember what they’ve eaten or where they’ve been, and they don’t identify you or any of their friends -- every moment in their life would be like seeing the world for the first time.

But don’t be so quick to feel sorry for them. A new study has found that fish have a much better memory than we used to think. In fact, certain species of fish can even remember events from as long as 12 days ago. In the study, researchers from Mac Ewan University in Canada trained a kind of fish called African cichlids to go to a certain area of their tank to get food. They then waited for 12 days before putting them back in the tank again. Researchers used computer software to monitor the fish’s movements. They found that after such a long break the fish still went to the same place where they first got food. This suggested that they could remember their past experiences.

In fact, scientists had been thinking for a long time that African cichlids might have a good memory. An earlier study showed that they behaved aggressively（挑衅地）in front of certain fish, perhaps because they remembered their past “fights”. But until the latest findings, there was no clear evidence.

Just as a good memory can make our lives easier, it also plays an important part when a fish is trying to survive in the wild. “If fish are able to remember that a certain area contains safe food, they will be able to go back to that area without putting their lives at risks,” lead researcher Trevor Hamilton told Live Science.

For a long time, fish were placed far below chimpanzees, dolphins and mice on the list of smart animals. But this study has given scientists a new understanding of their intelligence.

It's a fact that we all dream. Some dreams seem to last for hours, others only for seconds. Some of us have strange dreams, some have interesting dreams, and some of us have unpleasant dreams. Tests in the 1980s showed that these dreams occur within 90-minute cycles, each cycle made up of six stages. In the last stage people experience rapid eye movement, known as REM, and it is in this stage that dreaming takes place. Eighty percent of people who were woken during this sixth stage could easily remember their dreams. On the other hand, when during the first five stages (NREM), only seven percent could describe a dream.

However, of these same people woken during the first five stages, 74% were able to remember thinking activity, although they would not call it a dream. NerysDee, who has written about dreams in a book called "Your Dreams and What They Mean" says: "Perhaps during NREM sleep we are sorting out our outer mundane problems, but in REM sleep we are dealing with inside matters." She also makes the following statement about 90-minute cycle: It may also prove the reason why insomniacs who wake in the middle of the night find it impossible to get to sleep again for at least an hour and a half. In other words, until they have missed out one complete 90-minute sleep period.

1.Which of the following statements about dreams is TRUE?

A. Everyone dreams but very few can recall what they dream.

B.Some people have long dreams and others have very short ones.

C. People can only remember unpleasant dreams.　

D.More than eighty percent of people can remember their dreams.

2.According to the tests in the 1980s, dreaming takes place­­______.

A.between each 90-minute cycle　　　　　　　 　　

B. at any time during 90-minute cycles

C.during the first five stages of 90-minute cycles　

D. in the last stage of 90-minute cycles

3.People woken during REM sleep can______.

A. hardly remember their dreams　　　　　

B. easily remember their dreams　　

C. only remember their dreams　　　　　　

D. partly remember their thinking activity

4."Insomniacs" are persons who______.

A. can always remember their dreams　　　

B. have trouble getting into sleep at night　

C. experience rapid eye movement　　　 　

D. usually wake after each 90-minute sleep period

A smart card is a card that is carried with either a microprocessor（微处理器）and a memory chip or only a memory chip that is not programmable（可编程的）. The microprocessor card can add, delete, and deal with the information on the card, while a memory-chip card can only do one thing.

Smart cards, unlike magnetic stripe cards, can do many different things and hold a lot of information. In this way, they do not need to get information from a faraway place when they are used.

Today, there are several kinds of smart cards, all of which are very popular in the market:

IC (Integrated Circuit) microprocessor cards: Microprocessor cards (chip cards) offer a larger memory and better security than the traditional magnetic（磁性的）stripe cards do. Chip cards can also hold data. These cards are used for many things. Thus, chips have been the main platform for cards that hold a secure digital identity. Some examples of these cards are: cards that hold money; cards that provide safe access to a network; cards that allow setting stop boxes on television to remain safe from privacy(隐私).

Optical（光学的）memory cards: Optical memory cards look like cards with a piece of CD on the top. Optical memory cards can store up to 4MB of data. But once written, the data can not be changed or removed. Thus, this type of card is good for keeping records, such as medical files, driving records or travel histories. Today, there are no processors in them (although this is coming in the near future). While the cards are almost as cheap as chip cards, the card readers are expensive.

When I was nine years old, I loved to go fishing with my dad. But the only thing that wasn’t very fun about it was that he could catch many fish while I couldn’t catch anything. I usually got pretty upset and kept asking him why. He always answered, “Son, if you want to catch a fish, you have to think like a fish”, I remember being even more upset then because, “I’m not a fish!” I didn’t know how to think like a fish. Besides, I reasoned, how could what I think influence what a fish does?

As I got a little older I began to understand what my dad really meant. So, I read some books on fish. And I even joined the local fishing club and started attending the monthly meetings. I learned that a fish is a cold-blooded animal and therefore is very sensitive to water temperature. That is why fish prefer shallow water to deep water because the former is warmer. Besides, water is usually warmer in direct sunlight than in the shade. Yet, fish don’t have any eyelids(眼皮) and the sun hurts their eyes... The more I understood fish, the more I became effective at finding and catching them.

When I grew up and entered the business world, I remember hearing my first boss say, “We all need to think like sales people.” But it didn’t completely make sense. My dad never once said, “If you want to catch a fish you need to think like a fisherman.” What he said was, “You need to think like a fish.” Years later, with great efforts to promote long-term services to people much older and richer than me, I gradually learned what we all need is to think more like customers. It is not an easy job. I will show you how in the following chapters.

1.Why was the author upset in fishing trips when he was nine?

A. He could not catch a fish.

B. His father was not patient with him.

C. His father did not teach him fishing.

D. He could not influence a fish as his father did.

2.What did the author’s father really mean?

A. To read about fish.

B. To learn fishing by oneself.

C. To understand what fish think.

D. To study fishing in many ways.

3.According to the author, fish are most likely to be found _________.

A. in deep water on sunny days

B. in deep water on cloudy days

C. in shallow water under sunlight

D. in shallow water under waterside trees
