[填空题]Redeveloping brownficlds offers a big potential market for______.
[单项选择] Genetic engineering holds great potential payoffs for farmers and consumers by making crops resistant to pests, diseases, and even chemicals used to kill surrounding weeds. But new research raises concerns that altering crops to withstand such threats may pose new risks from none other than the weeds themselves. This is due to the weeds ability to acquire genes from the neighboring agricultural crops. Researchers found that when a weed cross-breeds with a farm-cultivated relative and thus acquires new genetic traits possibly including artificial genes engineered to make the crop hardier the hybrid weed can pass along those traits to future generations.
"The result may be very hardy, hard-to-kill weeds," said Allison Snow, a plant ecologist at Ohio State University in Columbus who conducted the experiments over the past six years along with two colleagues. They presented their results last week at the annual meeting of the Ecological Society of America in Madison, Wisconsin.
A. the collapse of the agricultural industry
B. the rapid development of unintended plant hybrids
C. the development of pest and herbicide-resistant weeds
D. the difficulty to determine whether to make crops resistant to pests or not given the limited nature of current research

Electronic Teaching
The potential of closed-circuit television and other new electronic leaching tools is so great that it is fascinating to visualize "the school of tomorrow".
Televised lessons will originate from a central building having perhaps four or five master studios. The lessons will be carried into classrooms all over a city, or even an entire country.
After a televised lesson has been given, the classroom teacher will take over for tire all-important "follow-up" period. The students will ask any troublesome questions, and difficult points will be cleared up through discussion.
The teacher in the classroom will have additional electronic tools. On the teacher’s desk, the traditional chalk and erasers will have been replaced by a multiple-control panel and magnetic tape players. The tape machines will run pre-recorded lessons which pupils will follow by headphones. T
A. the school of tomorrow
B. classrooms
C. big buildings
D. master studios
[单项选择]PROBLEMS FACING POTENTIAL EXPORTERS
Many firms fail because when they begin exporting they have not researched the target markets or developed an international marketing plan. To be successful, a firm must clearly define goals, objectives and potential problems. Secondly, it must develop a definitive plan to accomplish its objective, regardless of the problems involved. Unless the firm is fortunate enough to possess a staff with considerable expertise, it may not be able to take this crucial first step without qualified outside guidance.
Often top management is not committed enough to overcome the initial difficulties and financial requirements of exporting. It can often take more time and effort to establish a firm in a foreign market than in the domestic one. Although the early delays and costs involved in exporting may seem difficult to justify when compared to established domestic trade, the exporter should take a more objective view of this process and careful
A. get professional advice.
B. study international marketing.
C. identify the most profitable markets.
D. have different objectives to other exporters.
