The advantages of using flashcards to build up a vocabulary are well known. You can buy sets of cards, or make your own, and carry them with you wherever you go. There’s no question this is useful and because you can use them in short bursts, it’s not too much for you. It can be fun. I don’t recommend drilling for hours at a time with flashcards.
If you want to use flashcard software, things get even better. There are many packages out there for maintaining and drilling flashcards. I recommend VTrain though there are many others.
One stands out, however: SuperMemo. Similar to Pimsleur, SuperMemo is engineered according to a carefully researched methodology (方法学) in order to test you on a card the very minimum number of times you need to see it for it to stick. When you look at a card, you give some feedback to the software on whether you got it right and how easy you found it. It uses this information, and that of your previous attempts, to decide when you will be shown the card next. It’s smart and it really works.
If you’re like me, the news is even better! I have a version of SuperMemo that runs on my PalmOS phone. Wherever I am, if I have my phone handy, I have thousands of flashcards with me too. Honestly, it would be worth purchasing a cheap Palm device only for this. You can pick one up for $20 or even less on eBay or elsewhere. Consider it, at least.
1.With SuperMemo, whether the next card will be shown depends on ________.
A. the time you look at the card
B. the information in the computer
C. the feedback one gives to the software
D. the times one attempts to do with a card
2.Which of the following is true according to the passage?
A. Using cards to study can be very tiring.
B. Don’t need to study with flashcards too long at a time.
C. There is not enough flashcards software at present.
D. Flashcard software can be carried wherever you go.
3.What is the main purpose of the author in writing the passage?
A. To introduce to us a way to build up a vocabulary.
B. To teach us how to make flashcards.
C. To suggest us buying flashcards.
D. To tell us how to use flashcard software.

DNA left at a crime scene could be used in the future to build up a picture of an offender’s face, it was revealed tonight.
A first step towards genetic mugshots has been taken by researchers in the US who link specific DNA markers with face shape. To identify the genes, they focused on known mutations(突变) that cause changes of the face and head. Normal versions of these genes were found to influence individual features. For instance, one gene affected the lips, another the shape and configuration of bones around the eyes, and a third the appearance of the mid-face and skull. In total, 20 genes had “significant effects” on facial appearance.
Lead scientist Professor Mark Shriver, from Pennsylvania State University, said: “We use DNA to match to an individual or identify an individual, but you can get so much more from DNA. Currently we can’t go from DNA to a face, or from a face to DNA, but it should be possible.” The implications are far reaching, raising the possibility of creating a data bank of facial types based on genetic markers. DNA from a crime scene could then be used to produce a rough image of the face of an offender or victim. Such genetic mugshots may be more reliable than computer-generated “e-fits” based on witnesses’ recollections. Other uses of the technique might include proving the identity of fathers in paternity cases, or visualising our remote ancestors from fossil DNA.
The scientists wrote in the online journal Public Library of Science Genetics: “Such predictive modelling could be forensically useful; for example, DNA left at crime scenes could be tested and faces predicted in order to help to narrow the pool of potential suspects. Further, our methods could be used to predict the facial features of descendants, deceased ancestors, and even extinct human species. In addition, these methods could prove to be useful diagnostic tools.” The team developed a model which first established a range of physical face shapes from people of mixed West African and European ancestry from the US, Brazil and Cape Verde. Measurements were taken of thousands of point co-ordinates on grids placed over 3D images of the faces.
Statistical methods were then used to determine the relationship between facial differences and the effects of gender, ethnic ancestry and individual gene variants.

When building houses, people used to think about not only the climate of the areas but also the building materials and the fashions for their houses. However, since electricity became more and more expensive, people began to pay much more attention to the energy they could get for their houses and the new ways they could find to protect their houses from both cold and heat.
Now, houses of an old yet new type have been widely built. In some parts of the world, people share their houses with their livestock（家畜）.During cold weather, they gather their cows, goats, or other animals and keep them on the first floor of their houses. The reasons are that the animals can be protected from the cold and that they can help to heat the houses as well. The body heat given off by the animals rises to the second floor of the houses, where people live. By sharing their houses with their livestock, people gain a source of heat.
People who live in or near cities do not usually keep livestock. However, home builders use the fact that heat rises. This natural law can be used in building houses in these areas. Instead of keeping livestock on the first floor, builders fill it with large rocks. As they are open to the sun’s rays during cold weather, these rocks take in heat. They also give off the heat, and, of course, the warm air rises into the living areas of the houses. So these houses are energy-saving.
House-building becomes a great challenge（挑战）to building designers and energy engineers. They try to meet this challenge by learning from old traditions and by using modern technology. And someday in the future, people will be able to live in more energy-saving houses.
1.What did people begin to consider as electricity was no longer cheap?
A. The climate of their areas. B. The energy for their houses.
C. The fashions for their houses. D. The building materials for their houses.
2.People in some areas gain a source of heat by _________.
A. keeping their livestock downstairs
B. protecting their livestock from the cold
C. sharing their houses only with their cows
D. living on the second floor with their livestock
3.The underlined words “natural law” in the third paragraph refer to the fact that ________.
A. heat raises the temperature in the houses
B. heat goes in the upward direction
C. heat goes up if temperature is raised
D. heat increases the temperature of rocks
4.From the passage, we can conclude that __________.
A. people will no longer consider building materials in the future
B. energy-saving buildings will become more popular in the future
C. almost all people will move into the houses heated by large rocks
D. energy engineers will devote themselves only to modern technology

Skyscrapers are the symbol of Urban life.City people are used to seeing tall buildings and apartments. Farms，on the other hand,are associated with rural(农村的)life.However，there are experts who think skyscrapers should become farms to meet the increasing food needs.
By the middle of this century, some scientists suggest，almost 80% of the earth's population could live in cities. In addition，the population could increase to 9.1 billion people during that time yet the amount of land available for farming will be the same.If current farming practices don't change，we will need an area of new land to produce enough food for the planet.
Vertical farms, where urban farmers could grow crops in environmentally friendly skyscrapers, could be the solution. In spite of concerns over high costs, experts want to make it a reality and use these skyscrapers to grow crops.
Vertical farms would have many advantages, supporters say. Unlike traditional farming, vertical farming could be free of chemicals and diseases. Besides, crops would not suffer from problems like flooding. Finally，vertical farms would reduce the cost and negative effects of transporting food over long distances.
Some argue that although crops growing in a tall glass building would get natural sunlight during the day，it wouldn't be enough. For this reason，vertical farms would need additional light sources(来源), such as artificial light.
Another way of growing fresh food is to build urban farms on rooftops. This more practical approach may be more achievable than the idea of farms in skyscrapers, researchers suggest. Experts agree that innovative(革新的)farming practices are needed to support the need for more food at affordable costs, both to the farmer and to the consumer,but the best ideas could be yet to come.
1.What primary problem could vertical farming settle？
A. Poor state of rural life.
B. Shortage of food supply.
C. High cost for transporting crops.
D. Environmental pollution by transitional farmings
2.What is the advantage of vertical farming?
A. It can produce organic food.
B. It requires little care.
C. It can benefit transport industry.
D. It needs very low cost.
3.What is a big challenge to make vertical farming a reality?
A. Farmable land. B. Crop diseases
C. Light sources. D. Climate conditions.
4.What can be the best title of the test?
A. Future Food Needs
B. Symbol of Urban Life
C. Farming on Rooftops
D. Farms of the Future
