一线名师提优试卷系列答案Dr. Glenn Tisman, a cancer specialist, knew his young neighbor, Ray Bateman, had an unusual mind. But he had no idea at the time that 12 - year – old
Ray had the ability to become his partner in cancer research.
Ray’s parents remembered that at age four, Ray surprised them by fixing a broken vacuum cleaner（吸尘器）. When he was ten, he speedily constructed the family color television from a kit. Later, he succeeded in assembling（组装） a complex stereo system after two experts had failed to do the job.
When Ray was ten, he convinced his parents to buy him a computer. In a short time, Ray was able to do amazing things with the computer. Ray shared his enthusiasm for computers with Dr. Tisman, who used a computer for his research. The two discussed computers and medicine frequently. Amazingly, Ray understood the biology and chemistry related to Dr. Tisman’s medical research without any previous instruction.
Ray then worked with Dr. Tisman after school. He helped conduct research with the equipment and kept it in working order. The purpose of the research was to test the effectiveness of mixing an old cancer drug with certain vitamins. Ray analyzed patient test results by computer, while Dr. Tisman handled all patient contact. Together, they came up with solid research that helped advance cancer treatment.
In 1988, 14 - year - old Ray went with Dr. Tisman to a meeting of the American Federation for Clinical Research（AFCR）, where Ray presented their initial research findings. Using terminology（术语） beyond the grasp of most kids his age, Ray told the scientists how the new drug mixture caused fewer and milder side effects for cancer patients.
A year later, Ray returned to the meeting to update the findings of his and Dr. Tisman’s research. By then, he had become well - known for his devotion to finding cures for sick patients. Stories about him appeared in hundred of newspapers around the world. He appeared on television newsc
asts and talk shows.
Ray continued to spend most free hours working with Dr. Tisman. The two began studying the effects of vitamins on babies inside the womb（子宫）. However, Ray’s main interest remained cancer treatment, and he continues his research today.

Students and Technology in the Classroom
I love my blackberry—it’s my little connection to the larger world that can go anywhere with me. I also love my laptop computer，as it holds all of my writing and thoughts. Despite this love of technology, I know that there are times when I need to move away from these devices(设备) and truly communicate with others.
On occasion, I teach a course called History Matters for a group of higher education managers. My goals for the class include a full discussion of historical themes and ideas. Because I want students to thoroughly study the material and exchange their ideas with each other in the classroom, I have a rule —no laptop, iPads, phones, etc. When students were told my rule in advance of the class, some of them were not happy.
Most students assume that my reasons for this rule include unpleasant experiences in the past with students misusing technology. There’s a bit of truth to that. Some students assume that I am anti-technology. There’s no truth in that at all. I love technology and try to keep up with it so I can relate to my students.
The real reason why I ask students to leave technology at the door is that I think there are very few places in which we can have deep conversions and truly engage complex ideas. Interruptions by technology often break concentration and allow for too much dependence on outside information for ideas. I want students to dig deep within themselves for inspiration and ideas. I want them to push each other to think differently and make connections between the course material and the class discussion.
I’ve been teaching my history class in this way for many years and the evaluations reflect student satisfaction with the environment that I create. Students realize that with deep conversation and challenge, they learn at a level that helps them keep the course material beyond the classroom.
I’m not saying that I won’t ever change my mind about technology use in my history class, but until I hear a really good reason for the change, I’m sticking to my plan. A few hours of technology-free dialogue is just too sweet to give up.
【小题1】Some of the students in the history class were unhappy with____
| A．the course material | B．the author’s class regulations |
| C．discussion topics | D．others’ misuse of technology |
| A．explore | B．accept | C．change | D．reject |
| A．keep students from doing independent thinking |
| B．encourage students to have in-depth conversations |
| C．help students to better understand complex themes |
| D．affect students’ concentration on course evaluation |
| A．is quite stubborn |
| B．will give up teaching history |
| C．values technology-free dialogues in his class |
| D．will change his teaching plan soon |
We do not know when man first began to use salt, but we do know that it has been used in many different ways throughout history. Historical evidence shows, for example, that people who lived over 3,000 years ago ate salted fish. Thousands of years ago in Egypt, salt was used to preserve (保存) the dead.
Stealing salt was considered a major crime (罪行) during some periods of history. In the eighteenth century, for example, if a person was caught stealing salt, he could be put in prison and his ears could be cut off.
In the Roman Empire, one of the most important roads was the one that carried salt from the salt mines to Rome. Guards were stationed along the route to protect against salt thieves, and they received their pay in salt, thus bringing the English word, salary. Any guard who fell asleep while on duty was thought to be “not worth his salt”, and as a result he would get a little less salt on his next payday. The expression, “not worth his salt”, is still used today in English.
In the modern world salt has many uses beyond the dining table. It is used in making glass and airplane parts, in the growing of crops, and in the killing of weeds (杂草). It is also used to make water soft, to melt (融化) ice on roads and highways, to make soap, and to fix colors in cloth.
Salt can be got in various ways besides being taken from mines underground. Salt water from the ocean, salt water lakes or small seas can be used to make salt. Yet, no matter where it comes from, salt will continue to play an important role in the lives of people everywhere.

As people slowly learn to cure diseases, control floods, prevent hunger, and stop wars, fewer people die every year. As a result, the population of the world is becoming larger. In 1925 there were about 2 billion people in the world; today there are over 6 billion.
When the number rises, extra mouths must be fed. New lands must be brought under development, or land already farmed must be made to produce more crops. In some areas the land is so over-developed that it will be difficult to make it provide more crops. In some areas the population is so large that the land is divided into too tiny units to make improvement possible with farming methods. If a large part of this farming population went into industrial work, the land might be farmed much more productively (多产地) with modern methods.
There is now a race for science, technology, and industry to keep the output of food rising faster than the number of people to be fed. New types of crops, which will grow well in bad weather, are being developed, so there are now farms beyond the Arctic Circle in Siberia and North America. Irrigation (灌溉) and dry-farming methods bring poor lands under the plough. Dams hold back the waters of great rivers, which can provide water for the fields in all seasons and provide electric power for new industries. Industrial chemistry provides fertilizer to suit different soils. Every year, some new methods are made to increase or to protect the food of the world.
