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 recognize 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 MacEwan 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.

    When you go to the doctor, you like to come away with a prescription．It makes you feel better to know you will get some medicine. But the doctor knows that medicine is not always needed. Sometimes all a sick person needs is some reassurance that all will be well. In such cases the doctor may prescribe a placebo.

    A placebo is a sugar pill, a harmless shot, or ail empty capsule. Even though they have no medicine in them, these things seem to make people well. The patient thinks it is medicine and begins to get better. How does this happen?

    The study of the placebo opens up new knowledge about the way the human body can heal itself. It is as if there was a doctor in each of us. The doctor will heal the body for us if we let it. But it is not yet known just how the placebo works to heal the body. Some people say it works because the human mind fools itself. These people say that if the mind is fooled into thinking it got medicine, then it will act as if it did, and the body will feel better.

    Placebos do not always work. The success of this treatment seems to rest a lot with the relationship between the patient and the doctor. If the patient has a lot of trust in the doctor and if the doctor really wants to help the patient, then the placebo is more likely to work. So in a way, the doctor is the most powerful placebo of all.

    A placebo can also have bad effects. If patients expect a bad reaction to medicine, then they will also show a bad reaction to the placebo. This would seem to show that a lot of how you react to medicine is in your mind rather than in your body. Some doctors still think that if the placebo can have bad effects it should never be used. They think there is still not enough known about it.

    The strange power of the placebo does seem to suggest that the human mind is stronger than we think it is. There are people who say you can heal your body by using your mind. And the interesting thing is that even people who swear this is not possible have been healed by a placebo．

    Have you eaten too much over the holidays? You should try fidgeting for a while. Those around you might not like it, but scratching (moving your nails (指甲) against a part of your body) and twitching (moving suddenly and quickly when you don't want to) is an important way of burning up calories (卡路里).

    American researchers have found that some people's squirming (continuously turn your body when nervous) and wigging (move in small movements, especially from side to side) equals (等于) several miles of slow running each day.

    The scientists, based at the National Institute of Health's laboratory in Phenix, Arizona, are studying why some people get fat and other stay slim.

    In one study 177 people each spent 24 hours in a room in the institute where the amount (量) of energy is measured by their oxygen and carbon dioxide (二氧化碳) levels. By the end of the day, some people had burned up 800 calories in toe-tapping, (moving the front part of your foot up and down) finger-drumming (hitting your fingers continuously and lightly against something hard) and other nervous habits. However, others had burned up only 100 calories.

    The researchers found that slim（苗条的）women fidget more than fat women, but there was no significant difference in men. Heavy people burn up more energy when they fidget than do thin people.

    Teachers' Day is, interestingly, not celebrated on the same day all over the world. In some countries it is marked by a holiday, in others it is a working day.

    International Teachers' Day is celebrated on October 5. Being held ever since 1994, it is in honor of teachers' organizations worldwide. Its aim is to encourage supports for teachers and to meet the needs of students.

    China In 1939, Teachers' Day was set for August 27, Confucius' birthday. In1951, the celebration was stopped. However, it was founded again in 1985, and the day was changed to September 10.

    India   Teachers' Day is celebrated on September 5 in honour of Dr. Sarvepalli Radhakrishnan, the second president of India, whose birthday falls on that day.

    Russia ― In Russia, Teachers' Day was celebrated on the first Sunday of October between 1965 and 1994. Since 1994, the day is observed on the October 5, just the same day as World Teachers Day.

    The US   In the US, Teachers' Day is non-official holiday. It is celebrated on the Tuesday of the first full week of May. A number of activities are organized in schools to honor teachers. The celebrations can continue for the whole week of May.

    Thailand   In Thailand, National Teachers' Day is celebrated every year on January 16. The first Teachers' Day was held in 1957. The day is a holiday in schools.

Time is precious for students especially during finals. Having good skills of time management becomes so important. But how can you manage your time?

Get some sleep.

When things get rough, sleep often gets cut out of your schedule. The lab report has to be done by tomorrow morning, so... no sleep tonight, right? Wrong.{#blank#}1{#/blank#} Your brain will run slower, and you'll be super tired all the time. So even if it sounds strange, spare time to get quality sleep.

Prioritize (划分优先顺序) often.

Keep a running list of the major tasks that you're performing. Change it as often as necessary and refer to it when you feel worried about all the things you have to do.{#blank#}2{#/blank#} You can't do so many all at once.

{#blank#}3{#/blank#}

Although you might try hard to plan every, detail of your routine, sometimes things just happen. You might get sick or your roommate loses your keys. Set aside as much time as you can each day for emergencies. That way, you needn't deal with the unexpected in a rush.

Schedule time to relax.

Finals can be surprisingly stressful, and you may not realize how much harm they do to you until they're over. Workload can sometimes be unbearable. Schedule some free time to make you mentally recharged.{#blank#}4{#/blank#}

Ask for help when you need it.

Asking for help is pretty normal during leaning. It's rare to find a student who can make it through school life without any help.{#blank#}5{#/blank#} There are lots of places that can give you a hand at the end of a term.

A. Get on well with roommates.

B. Leave extra time, just in case.

C. Thus, don't hesitate to seek help when necessary.

D. Feeling worried may help you accomplish nothing.

E. If you feel depressed, focus on the one at the top of the list.

F. Let your brain take a break so it can go back to work efficiently.

G. Not getting enough sleep can actually cost you more time in the long run.
