Animals seem to have the sense to eat when they are hungry and they do not eat more than their bodies need．It has been demonstrated（证明）that rats will, when given a choice over a period of time, prefer water with vitamins to water without vitamins even though there is no difference in taste or smell between the two water bottles．When a fragrant（香的）flavor（作料）was added to the vitamin-enriched water, the rats did seem to prefer it and kept drinking it ,even after the vitamins were switched to the clear water．In time, however, they broke the habit and went back to where the necessary vitamins were．

In a classic experiment, babies of 6 to 12 months old were placed in a cafeteria（自助） feeding arrangement, with a wide selection of baby food before them．They were given whatever food they pointed to or appeared interested in．We are told that at first they showed some unusual eating patterns, but that over a period of time they managed to select well-balanced diet．

So, in selecting food, rats and babies do seem to know and act on what's best for them．Apparently, there is a kind of “body wisdom”,  which humans soon lose．Most of us do not eat as wisely as we could．Many of our food preferences are culturally determined and influenced by long-established habits．Some people eat fox, dog and blackbirds, while we eat cows and pigs．So what people eat and how much they eat seems to be greatly influenced by what is going on around them．

In the experiment on rats, a fragrant flavor was added to the rats’ drinking water to _____________ .

   A. encourage rats to drink vitamins-enriched water

   B. find out rats’ preference in flavor

   C. test whether rats know which drink is good for them

   D. demonstrate the vitamins are tasteless

A．adults know better than babies what kind of food are good for their health

D．adults have more choices of food than babies in eating patterns

The author implied in the passage that most of us_________．

A．eat a balanced diet                      

B．choose the food that is of nutrition

C．have the habits influenced by the surroundings 

D．like to eat the food with a fragrant flavor．

As far as their eating habits are concerned, babies and rats are similar in that_________．

A．both have the wisdom to choose a balanced diet

B．both prefer flavored food and drink

C．both have the same eating patterns

D．both develop a taste for the same kinds of flavors

Towards the end of Middle English, a sudden change in pronunciation started, with vowels being pronounced shorter and shorter. From the 16^th century the British had contact with people from around the world. This means that many new words and phrases entered the language. The invention of printing also meant that there was a common language in print. Books became cheaper and more people learned to read. Spelling and grammar became fixed and the dialect （方言）of London became the standard. In 1604, the first English dictionary was published.
The numbers of words in Early Modern English and Late Modern English differ. Late Modern English has a lot more words because of two main factors: firstly, the Industrial Revolution created a need for new words; secondly, the British Empire covered one quarter of the earth’s surface, and the English language took in foreign words from many countries.
From around 1600, the English colonization(殖民地化)of North America resulted in the creation of American English. Some English pronunciation and words  froze when they reached America. In some ways, American English is more like the English of Shakespeare than modern British English. Some expressions that the British call “ Americanisms” are in fact original （原先的）British expressions that were preserved (保存) in the colonies but were lost in Britain. Spanish also had an influence on American English, with words like canyon, ranch, stampede and vigilante being examples of Spanish words that entered English. French words and West African words also influenced American English.
Today, American English is the most influential(有影响力的). But there are many other kinds of English around the world, including Australian English, New Zealand English, Canadian English, South African English , Indian English and Caribbean English. They have differences.
【小题1】What can we know from Paragraph 1?

Geniuses amaze us，impress us and make us all a little jealous. How do they differ from the average person？Scientists are working hard to figure out that answer. Tune in to the National Geographic Channel to find out about the discoveries they’re making in the series My Brilliant Brain.
When Marc Yu was only two years old，he began to play the piano. After a year, he started learning pieces by Beethoven. Now he’s a world-famous concert pianist at age eight. He learns newer and more difficult pieces with ease and can identify any note he hears. He seems to be specially designed for music. In Born Genius, National Geographic looks at the science behind child prodigies （神童） to explain why some children seem to be born without limits.
Geniuses didn’t come naturally to Tommy McHugh. His came only after he nearly died from bleeding in his brain. After recovering, McHugh’s head was filled with new thoughts and picture. So, he began to express them in the form of poetry and art. Now, he’s a seemingly unstoppable creative machine. Suffers of brain injury have shown that great mental ability can sometimes come from damage or disease. Accidental Genius explores this puzzling relationship.
Can normal people be trained to be geniuses? Susan Polger has shown no sign of extraordinary intelligence. Yet, during her childhood, she studied thousands of chess patterns and learned to recognize them immediately. As a result, she was able to beat skilled adult players by age 10 and can now play up to five games at the same time without even seeing the boards. Make Me a Genius examines what is takes to turn an ordinary brain into that of a genius.
If becoming a genius were easy, we’d all be done. Yet, there is much more to super intelligence than simply being born lucky. Learn more about amazing brains this month on National Geographic’s My Brilliant Brain.
【小题1】 In paragraph 2, Marc Yu’s story tells us_________________.

So long as teachers fail to distinguish(区别, 辨认) between teaching and learning, they will continue to undertake to do for children that which only children can do for themselves. Teaching children to read is not passing reading on to them. It is certainly not endless hours spent in activities about reading. Douglas insists that“ reading cannot be taught directly and schools should stop trying to do the impossible”.

　Teaching and learning are two entirely different processes. They differ in kind and function. The function of teaching is to create the conditions and the climate that will make it possible for children to devise the most efficient system for teaching themselves to read. Teaching is also public activity. It can be seen and observed.

　Learning to read involves all that each individual does to make sense of the world of printed language. Almost all of it is private, for learning is an occupation of the mind, and that process is not open to public observation.

　If teacher and learner roles are not interchangeable ,what then can be done through teaching that will aid the child in the quest（探索）for knowledge? Smith has one principal rule for all teaching instructions. “Make learning to read easy, which means making reading a meaningful, enjoyable and frequent experience for children. ”

　When the roles of teacher and learner are seen for what they are, and when both teacher and learner fulfill them properly, then much of the pressure and feeling of failure for both is eliminated(除去, 剔除). Learning to read is made easier when teachers create an environment where children are given the opportunity to solve the problem of leaning to read by reading.
