If we were asked exactly what we were doing a year ago，we should probably have to say that we could not remember. But if we had kept a book and had written in it an account of what we did each day, we should be able to give an answer to the question．

    It 1s the same in history．Many things have been forgotten because we do not have any written account of them. Sometimes men did keep a record of the most important happenings in their country, but often it was destroyed by fire or in a war．Sometimes there was never any written record at all because the people of that time and place did not know how to write．For example，we know a good deal about the people who lived in China 4,000 years ago，because they could write and leave written records for those who lived after them．But we know almost nothing about the people who lived even 200 years ago in Central Africa，because they had not learned to write．

    Sometimes，of coures，even if the people cannot write，they may know something of the past．They have heard about it from older people，and often songs, dances and stories have been made about the most important happenings, and these have been sung，acted and told for many generations，for most people are proud to tell what their fathers did in the past．This we may call”remembered history”．Some of it had been written down. It is not so exact or so valuable to us as written history is，because words are much more easily changed when used again and again in speech than when copied in writing．But where there are no written records，such spoken stories are often very helpful．

    Art museums are places where people can learn about various cultures. The increasingly popular "design museums" that are opening today, however, perform quite a different role. Unlike most art museums, the design museums show objects that are easily found by the general public. These museums sometimes even place things like fridges and washing machines in the centre of the hall.

    People have argued that design museums are often made use of as advertisements for new industrial technology. But their role is not simply a matter of sales — it's the honouring of excellently invented products. The difference between the window of a department store and the showcase(玻璃陈列柜) in a design museum is that the first tries to sell you something, while the second tells you the success of a sale.

    One advantage of design museums is that they are places where people feel familiar with the exhibits. Unlike the average art museum visitors, design museum visitors seldom feel frightened or puzzled. This is partly because design museums clearly show how and why mass-produced products work and look as they do, and how design has improved the quality of our lives. Art museum exhibits, on the other hand, would most probably fill visitors with a feeling that there is something beyond their understanding.

    In recent years, several new design museums have opened their doors. Each of these museums has tried to satisfy the public's growing interest in the field with new ideas. London's Design Museum, for example, shows a collection of mass-produced objects from Zippo lighters to electric typewriters to a group of Italian fish-tins. The choices open to design museums seem far less strict than those to art museums, and visitors may also sense the humorous part of our society while walking around the exhibits.

    The words “protect animals” appear everywhere in books and on screens because some animals are in danger of dying out. But sometimes the reality can be a little different from what people read or watch.

    Florida, US, has held its first bear hunt since 1994. The local government gave people nearly 4,000 permits to kill black bears. And more than 200 were killed on Oct 24.

    Animal protection groups protested this decision. But local officials explained that the black bear population had grown to 3,500 and become a menace to local people. In the past two years, bears have hurt at least four people in Florida.

    This brings an old question back into the spotlight – which is more important, protecting animals or protecting people's interests?

    This question is asked in other countries too. In Switzerland, a wolf was sentenced to death by the Swiss government months ago. This is because the wolf killed 38 sheep and local people lost a lot of money. Days ago in China, three old men were arrested for killing a serow(鬣羚), a protected species. But they insisted they didn't know about this and killed the animal because it ruined their crops.

    However, these stories don't always mean that animal protection stops due to human interests, especially involving economic development. A man named Zhou Weisen set up a wild animal base in Guilin, Guangxi. He saved over 170 tigers and 300 bears. But his base also offered jobs to local people.

    “There may never be a standard answer to the question of whether we should give more attention to the environment or human development,” said Robert May, a British biologist at Oxford University. “But we shouldn't push either one to the side, as the future is hanging in the balance.

    A lack of sleep causes many medical conditions that greatly affect the quality of life. While no one knows why we sleep, it is a universal biological need.{#blank#}1{#/blank#}

    How much sleep do I actually need?

    A study in Finland found that the amount of sleep that relates to the fewest sick days was 7.63 hours a night for women and 7.76 hours for men.{#blank#}2{#/blank#}When we get sleep fewer than seven hours or our sleep often falls below six hours, we are at an increased risk of health problems.

    Today, some people practice “polyphasic (一昼夜活动和休息多次的)sleep”,based on the idea that by dividing your sleep into parts, you can get away with less of it .Professor Dinges concludes it's possible to train oneself to need less sleep in short periods.{#blank#}4{#/blank#}And he notes that even for those who can function well on less sleep, we still don't know how the practice might be affecting chemical processes, mood, and other factors.

    I can't sleep. Is my phone really keeping me up?

    When light enters your eye, it hits your retina to send signals to the hypothalamus (下丘脑),which controls sleep cycles. When your retina takes in less light, your hypothalamus assumes it's time to sleep and it'll signal the pineal gland (松果腺)to make you sleepy. And when the hypothalamus senses light, it tells the pineal gland to stop its work.{#blank#}5{#/blank#} Some research suggests that the light from phones and tablets are especially influential in human sleep cycles.

A. Adequate sleep can benefit us a lot.

B. Can I train myself to need less sleep?

C. How can I make myself sleep less?

D. No animal with a brain can survive without it.

E. This is why we're told to minimize screen time before bed.

F. And most adults function best after seven to nine hours of sleep a night.

G. But he adds it doesn't seem possible to train oneself to need less sleep per 24-hour cycle.

    What is your favorite color? Do you like yellow, orange, red? If you do, you must be an optimist, a leader, an active person who enjoys life, people and excitement. Do you prefer graysand blues? Then you are probably quiet, shy and you would rather follow than lead. If you love green, you are strong-minded and determined. You wish to succeed and want other people to see you are successful. At least this is what psychologists tell us, and they should know, because they have been seriously studying the meaning of color preference, and the effect that colors have on human beings. They tell us that we don't choose our favorite color as we grow up. If you happen to love brown, you did so as soon as you opened your eyes, or at least as soon as you could see clearly.

    A yellow room makes us feel more cheerful and comfortable than a dark green one, and a red dress rings warmth and cheer to the saddest winter day. On the other hand, black is depressing. Light and bright colors make people not only happier but also more active. It is a fact that factory workers work better, harder, and have fewer accidents when their machines are painted orange rather than black or dark grey.

    Remember, then, that if you feel low, you can always brighten your day or your life with a new shirt or a few colorful things. Remember also that you will know your friends and your enemies better when you find out what colors they like and dislike. And don't forget that anyone can guess a lot about your character when you choose a piece of handkerchief.

How Did Poetry Begin?

Poems can make you feel emotions, like anger or sadness, depending on the words and how they are put together. That is the 1 of poetry. 

Poetry 2 even before humans knew how to read and write, dating back to around 3000 BCE. Some of the earliest poetry was 

3 or sung, and was used as a way to record and pass down historical and religious stories and cultural traditions from one generation to the next. Since writing was not practised then, certain sounds and rhymes were used to make these stories 4 and therefore, memorable. 

There are 5 three types of ancient poetry. The first was an epic(史诗) or long narrative(叙事的) poetry usually about a 6

event. The second type was lyric(抒情的) poetry or poetry that 7

personal feelings. Finally there was drama or stories written in verse and usually 8 like Greek tragedies and Shakespeare's plays. 

The invention of the printing press(印刷机) in the 15th century brought poetry to the common people. This was followed by several major literary periods, during which poetry 9 dramatic changes. They started with Europe's Renaissance period from the 14th to the 16th century, which first helped poetry and poets like Shakespeare and Sir Walter Raleigh become popular. 

The Romantic period saw 10 poems that expressed a poet's joys, hopes, and sorrows in a conversational tone. Then came the Victorian era, which saw the 11 of structured poems and the birth of modern "12 verse" poetry. American poet Walt Whitman's Leaves of Grass is 13 to be the first example of free verse poetry. 

Modern poetry is a 14 of all of these styles. We still see rhymes in children's poems and in the popular African-American styles of hip hop and rap music, which are a 15 of rhymed poetry put to a musical beat.
