题型：不详难度：来源：
The smartest rat among the first six that the government is teaching to locate landmines equipment planted by rebels(叛乱者) has a 90 percent success rate in locating landmines material in her lab training.
Police animal trainers, tired of seeing their landmines-smelling dogs blown up by stepping on mines, hope the white-furred, pink-eyed creature will lead her classmates through coming open field tests and then into the country mine fields before the end of the year. It takes about 400 grams of pressure to detonate (引爆) a mine while Lola only weighs about 220 grams. “The dogs can easily set off the landmines, sometimes killing people nearby,” they said.
Police animal trainer Jose Pineda says that rats have more sensitive noses than dogs, which should allow them to better smell out mines in difficult terrain (地形).
Plus, it takes the police about six months to train mine-smelling dogs. Training the rats is expected to take about half that time once the program is established.
Trainers think that they are much smarter than the dogs. The second-best scorer in the laboratory is Lucrecia, with an 83 percent success rate. Males, such as one named Runcho, have fallen behind until now but may do better in the coming field tests. Pineda said that the next step of training will present new challenges to the rats as they are sure to meet distractions (分心的事) in the open.

解析
试题分析：本文叙述了哥伦比亚的警察用老鼠去嗅出地雷减少对人的伤害和财产的损失，文中给出了为什么用老鼠去嗅出地雷，而不用狗，因为一是老鼠它的嗅觉比狗的灵敏。二是老鼠的身体轻，不会引爆地雷。三是训练老鼠用的时间比训练狗用的时间短。
小题1:词义猜测题。根据home to the world’s highest number of mine-related deaths and injuries last year. 由于人们踩到了地雷而失去生命，故选B。
小题2:细节理解题。根据rats have more sensitive noses than dogs, 它有好的嗅觉；Lola only weighs about 220 grams. “The dogs can easily set off the landmines, 因为这种鼠身体轻不会引爆炸弹；it takes the police about six months to train mine-smelling dogs. Training the rats is expected to take about half that time once the program is established.训练这种鼠花费的时间段，只有选项C没有提到，故选C。
小题3:推理判断题。根据Males, such as one named Runcho, have fallen behind until now but may do better in the coming field tests.可知到目前来看雌性鼠比雄性鼠要做的好，故选B。
小题4:标题归纳题。根据哥伦比亚的警察培训老鼠来嗅出地雷，故选D。
点评：做词义猜测题，要根据词、词组、句子所在的语境上下文来判断其意义。因此熟练掌握一些猜词技巧是做好这类题的关键。命题者在出这类题时惯用常规词义来麻痹考生，我们要特别注意熟词生义，切不可脱离语境主观臆断。

举一反三
A team of scientists from Scotland say “yes”. They’ve engineered special chickens that lay eggs with disease-treating drugs inside.
These eggs come from chickens that have been engineered to produce certain drugs inside their egg whites.
These drugs are made of molecules called proteins(蛋白质). Animals make thousands of proteins — they’re the main element in skin, hair, milk and meat. Since animals can make proteins easily, they’re good candidates (候选者) for making protein drugs.
Researchers have already made cows, sheep and goats produce protein drugs in their milk. But chickens are cheaper to take care of, need less room, and grow faster than these other animals. Those qualities could make chickens a better choice to become living drug factories, says Simon Lillico of the Roslin Institute near Edinburgh, Scotland.
Lillico and a team of researchers changed chickens’ DNA — the code that tells cells how to make proteins — so that the birds’ cells made two protein drugs. One drug can treat skin cancer, and the other treats a nerve disease called multiple sclerosis (多发性硬化).
The scientists changed the chickens’ DNA so that the birds made these drugs only in their egg whites. This protects the chickens’ bodies from the drugs’ possible harmful effects and makes it easy for scientists to collect the drugs.
小题1:If you cut your finger, you may use ________ to cure it.
| A．painkillers in a tablet | B．antibiotic cream from a tube |
| C．chicken eggs | D．protein drugs |
| A．Scientists from Scotland have succeeded in packing medicine into chicken eggs. |
| B．The drugs are made of molecules called proteins. |
| C．Scientists chose chickens for their experiments because chicken eggs taste delicious. |
| D．The animals are good candidates for making protein drugs. |
| A．treat lung cancer | B．help reduce headache |
| C．change people’s DNA | D．treat multiple sclerosis |
| A．eating eggs is the best choice for the patients now |
| B．scientists changed the chicken’s DNA and put all the drugs in chicken eggs |
| C．we may eat special eggs as drugs when we are sick in the future |
| D．the drugs produce harmful effects on the chicken’s bodies |
| A．Chicken Eggs to Replace Medicine | B．Chicken Eggs as Drug |
| C．Chicken Eggs and Medicine | D．Chicken Eggs and Animal Milk |

It can cause __4__ damage to their bodies and lead to death. Research shows that many people get sick and even die from eating sea turtle meat.
In the US, most people have never eaten turtle. This is because turtles are 5 by the United States law, which makes it 6 to harm or kill these amazing animals. “But many people in other countries still eat them,” explains Nichols. “Our first 7 was to save turtles; now we must save 8 too.”
Davis said he also wants to send out a bigger 9 that we should protect the oceans. “The health of the ocean, animals in the ocean, and our own health are all 10 . A clean ocean is really good for us too because of the food we eat from there.”

Personal Air Travel
The idea: flying cars
Developments in light small plane technology will make it possible for everyone to own what are, in fact, flying cars. They will have closed cabins, heating, stereos and room for two people.
You will take off from a field near your home and fly to towns and cities. After landing, you will take off the fixed wing and continue your journey by road just as if you were traveling by car.
Fuel efficient engines and the advantage of being able to travel in the sky will keep costs and the environmental influence down.
Flying for Fun
The idea: Jet Packs
The idea was a hit when a stuntman (特技演员) flew around on one during the opening ceremony of the 1984 Los Angeles Olympics, which was very successful.
You’ll be able to use the equipment－roughly the size of two scuba tanks fastened to your back－for short journeys.
They will be handy for cleaning hard-to-reach windows, arriving in style at a party and shopping.
Taxis
The idea: driverless taxis
These computer-controlled taxis will take you wherever you want along a fixed route, whenever you want to go.
For the price of one person’s bus fare, several people can ride at speeds of up to 25 mph, and there will be fences to guard against accidents.
There will be little, if any, wait for the use of the taxis, which will leave from stations and will be used by prepaid cards.
The taxis, which will travel on a 1.5 m-wide track, will use 75% less energy per passenger than a car and 50% less than a bus.
小题1:The passage is mainly about ________.
| A．future travel | B．big ideas and dreams |
| C．advanced technology | D．the influence of travel |
| A．will operate only in the sky |
| B．will be more expensive than common cars |
| C．will have few bad effects on the environment |
| D．won’t be equipped with things similar to what cars have |
| A．attend a party | B．clean high windows |
| C．go shopping | D．have a long journey |
| A．we can go wherever we want in them |
| B．they will be both convenient and safe |
| C．it costs more to take them than to take ordinary cars |
| D．they will be operated by computers as well as by people |
The class sits in a circle with their eyes shut and they count from one to ten: someone starts, the 36 voice comes from the far right, a third from the other side.
The aim of the game is to 37 for an opportunity to shout out the 38 without clashing (相撞) with another voice or leaving a pause. On the first try, 39 of the young Germans try to be first, while a few are too shy to join in. But by the fifth 40 , they develop a rhythm (节奏) . The message gives other people space but also claims your own. This is a requirement for social well-being.
Unlike schools in other nations, German schools do not usually have school sports teams or seek to build school spirit. Many teens admit they are 41 and confused, but school is not usually the place to find relief.
The Willy Hellpach School in Heidelberg is the first in the nation to develop a happiness 42 It is 43 for 17-19years old students to prepare for university entrance exams. "The course isn"t there to make you happy," Ernst Fritz-Schubert, the school principal, warned pupils, " 44 rather to help you discover the ways to become happy. "
Cooking a meal together will be one of the class 45 , along with improving body language under the 46 of two professional actresses.
The course is taught for three periods a week. Despite the happy subject, the pupils themselves insist it is no laughing matter.
"In the first period, we had to each say something 47 about another member of the class and about ourselves. No laughing at people or teasing," said Fanny, 17.
The message is that self-esteem (自尊) improves 48 too.
Research by the school shows it is not the first to start happiness classes and they also exist at some US universities, but are mainly based on positive thinking, using 49 from studies of depression.
"That would be too one-sided for us. We want to show how decent (好的) food or exercise can help too," the principal said.

Today things are different. The world has become too crowded. We are using up our natural resources too quickly, and at the same time we are polluting our environment with dangerous chemicals. If we continue to do this, human life on the earth will not survive.
Everyone realizes today that if too many fish are taken from the sea, there will soon be none left. Yet, with modern fishing methods, more and more fish are caught. We know that if too many trees are cut down, forests will disappear and nothing will grow on land. Yet, we continue to use more powerful machines to cut down more and more trees.
We realize that if rivers are polluted with waste products from factories, we will die. However, in most countries waste is still put into rivers, but there are few laws to stop this.
We also know that if the population of the countries in the world is to rise at the present rate in a few years, there will not be enough food.
What can we do to solve these problems?
If we eat more vegetables and less meat, there will be more food available for everyone. Land that is used to grow crops can feed five times more people than land where animals are kept.
Our natural resources will last longer if we learn to recycle them.
The world population will not rise so quickly if people use modern methods of birth control.
Finally, if all of us think about the problem, we will have a better and cleaner planet in the future.
小题1:This passage mainly tells us about ______.
| A．the problems we are facing today about environment and the ways to solve them |
| B．the unlimited natural resources in the world |
| C．our rivers are being polluted by waste from factories |
| D．the ways early man protected the environment |
| A．If we eat more vegetables, more food can be saved. |
| B．In the past, there was no need for people to think about environmental protection. |
| C．If we keep on cutting trees, forests will disappear. |
| D．We shouldn’t take more and more fish out of the sea, or there will soon be no fish left. |
| A．Man is cleverer than any other animal. |
| B．Man will destroy himself if he doesn’t solve the problem. |
| C．Modern fishing methods are helpful in our fishing industry. |
| D．We should make more laws in order to survive. |
| A．will never be used up | B．are being polluted |
| C．are as plentiful as in the past | D．are being used up very quickly |
