What will people die of 100 years from now?If you think that is a simple question,you have not been paying attention to the revolution that is taking place in bio-technology(生物技术).With the help of new medicine,the human body will last a very long time.Death will come mainly from accidents,murder and war.Today’s leading killers,such as heart disease,cancer,and aging itself,will become distant memories.
In discussion of technological changes,the Internet gets most of the attention these days.But the change in medicine can be the real technological event of our times.How long can humans live?Human brains were known to decide the final death.Cells(细胞) are the basic units of all living things,and until recently,scientists were sure that the life of cells could not go much beyond 120 years because the basic materials of cells,such as those of brain cells,would not last forever.But the upper limits will be broken by new medicine.Sometime between 2050 and 2100,medicine will have advanced to the point at which every 10 years or so,people will be able to take medicine to repair their organs(器官).The medicine,made up of the basic building materials of life,will build new brain cells,heart cells,and so on—in much the same way our bodies make new skin cells to take the place of old ones.
It is exciting to imagine that the advance in technology may be changing the most basic condition of human existence,but many technical problems still must be cleared up on the way to this wonderful future.According to the passage,human death is now mainly caused by _______.
| A．diseases and aging | B．accidents and war |
| C．accidents and aging | D．heart disease and war |

| A．heart disease will be far away from us |
| B．human brains can decide the final death |
| C．the basic materials of cells will last forever |

We can learn from the passage that _______.
| A．human life will not last more than 120 years in the future |
| B．humans have to take medicine to build new skin cells now |
| C．much needs to be done before humans can have a longer life |

Many people go to school for an education. They learn languages, history, geography, physics, chemistry and mathematics. Others go to school to learn a skill so that they can make a living. School education is very important and useful. Yet no one can learn everything from school. A teacher，no matter how much he knows can not teach his students everything they want to know. The teacher’s job is to show his students how to learn. He teaches them how to read and how to think. So much more is to be learned outside school by the students themselves.
It is always more important to study by oneself than to memorize some facts or a formula(公式). It is actually quite easy to learn a certain fact in history or a formula in maths. But it is very difficult to use a formula in working out a maths problem. Great scientists, such as Einstein，Newton and Galileo didn’t get everything from school. But they were all so successful. They invented so many things for mankind. The reason for their success is that they worked hard all their lives, wasting not a single moment. They would ask many questions as they read and they did thousands of experiments.
Above all, they knew how to use their brains.. The subject which is not spoken of in the article is _____
| A．maths | B．history | C．physiology（生理学） | D．physics |

. Who does the article say didn’t waste a single moment?

A beautiful and very successful actress (女演员) was the star for a new musical show.

An African farmer had heard tales about other farmers who had made millions of dollars by discovering diamond mines. These tales so excited the farmer that he could hardly wait to sell his farm and go prospecting for diamonds himself.
So he sold the farm and spent the rest of his life wandering the African continent, searching unsuccessfully for the shining stone that brought such high prices on the markets of the world.
Finally, broke and worn out, he threw himself into a river and drowned.
Meanwhile, back at the farm, the man who had bought his farm happened to be crossing a small river on the property one day when he saw something shining at the bottom of the river. He picked it up. It was a sparkling stone - a good size stone - and, admiring it, he later put it on his fireplace mantel（壁炉架） as an interesting curiosity.
Several weeks later, a visitor admired the stone, looked closely at it, lifted it in his hand and nearly fainted. He asked the farmer if he knew what he'd found. When the farmer said no, that he thought it was just a piece of crystal, the visitor told him he had found one of the largest diamonds ever discovered.
The farmer was astonished. He told the man that his small river was full of these brilliant stones, and his farmland was covered with them. Not all were as large, perhaps, as the one on his mantel, but they were sprinkled generously throughout his property.

Originally, both the British and the American spoke with a rhotic accent. Rhotic essentially means an accent where the letter “r” is pronounced strongly after a vowel (元音). Rhotic accents are strong in both the US and Scotland, but seem to have disappeared from British English and its derivatives, such as Australian English and New Zealand English.
The major American accent –– the typical accent of the mid-western US –– is rhotic, and British English is, as a rule, non-rhotic. Specifically, US speakers pronounce every “r”, wherever they appear in a word. Most British speakers (and you will note that there are some British Isle accents that are strongly rhotic, like US) do not pronounce every “r”. Americans stress the “r” at the end of words such as “teacher” or “neighbour”, but in many non-rhotic British accents it is more of a “schwa” (an unstressed sound) so it comes out as, “teacha” (unstressed) or “neighba”.
This main difference also differs across the country of origin. For example, the US has a clear difference in the accents between people of the north and south, not to mention less clear differences across the states. Similarly, British people have a different accent according to their locality. The “cockney (伦敦东区)” accent is greatly different to the middle and upper class accents.
Another common difference appears to be that Americans pronounce words such as “herbal” without the “h”. Syllables (音节) may be stressed differently, too. “Oregano” in the US tends to be pronounced “o–reg–a–no” while in British English it is more likely to be “o–reg–AH–no”.When a rhotic accent occurs, ______.
| A．the letter “r” is silent in any positions |
| B．the letter “r” is sounded after a vowel |
| C．the ending syllable of a word is stressed |
| D．the ending syllable of a word is unheard |
The underlined word “derivatives” in the first paragraph probably means “_____”.
| A．neighbours | B．ancestors |
| C．symbols | D．branches |
In non-rhotic British accents, ______.
| A．“bother” sounds the same as “buther” |
| B．“cheaper” sounds the same as “chapter” |
| C．“worker” sounds the same as “worka” |
| D．“painting” sounds the same as “paintin” |
Even in the original country of the specific English language, accents differ ____.
| A．from area to area | B．from person to person |
| C．from word to word | D．from stress to stress |
American people trend to pronounce words like “herbal” with the “h” ______.
| A．stressed | B．silent | C．changed | D．loud |
