It is in our mon interest to support concerned scientists and anizations, such as Friends of the Earth who demand required labeling of these food products and independent testing for safety and environmental impacts. 1. What is the main difference between conventional breeding and geic breeding? A) The former is based on sexual reproduction between like anisms while the latter can have genes even from bacteria and viruses. B) The former is unpredictable while the latter is predictable. C) The former is applied by farmers while the latter by scientists. 考試吧 ()第一個(gè)極力推崇人性化服務(wù)的專業(yè)考試培訓(xùn)網(wǎng)站 ！ 提供歷年試題，模擬試題，模擬盤，教程，專業(yè)課試題下載，考試培訓(xùn)等。 3. 作為市民應(yīng)如何響應(yīng)政府的號(hào)召。 考試吧 ()第一個(gè)極力推崇人性化服務(wù)的專業(yè)考試培訓(xùn)網(wǎng)站 ！ 提供歷年試題，模擬試題，模擬盤，教程，專業(yè)課試題下載，考試培訓(xùn)等。 The Decrease of Public Transportation Ticket Fare Part Ⅱ Reading Comprehension (Skimming and Scanning)(15 minutes) Directions: In this part, you will have 15 minutes to go over the passage quickly and answer the questions on Answer Sheet 1. For questions 17,choose the best answer from the four choices marked A), B), C) and D). For questions 810,plete the sentences with the information given in the passage. The Debate Over Geically Modified Foods For thousands of years farmers have used a process of selection and cross breeding to continually improve the quality of crops. Traditional breeding methods are slow, requiring intensive labor: while trying to get a desirable trait in a bred species, undesirable traits will appear and farmers must continue the process over and over again until all the undesirables are bred out. In contrast, anisms acquire one specific gene or a few genes together through geic modification, without other traits included and within a single generation. However, this technology too is inherently unpredictable and some scientists believe it can produce potentially dangerous results unless better testing methods are developed. Traditional breeding is based on sexual reproduction between like anisms. The transferred genes are similar to genes in the cell they join. They are conveyed in plete groups and in a fixed sequence that harmonizes with the sequence of genes in the partner cell. In contrast, bioengineers isolate a gene from one type of anism and collect it randomly into the DNA of a dissimilar species, disrupting its natural sequence. One of the main differences between conventional and geically modified crops is that the former involves crosses either within species or between very closely related species. However, GM crops can have genes from closely related species or even from bacteria and viruses. Benefits: one side of the debate Economical? GM supporters tell farmers that they stand to reap enormous profits from growing GM crops. It takes a shorter time to produce the desired product. It is precise and there are no unwanted genes. To produce the GM crops, modern biotechnology is used which requires highly skilled people and sophisticated and expensive equipment. Large panies need considerable investments in laboratories, equipment and human resources, hence the reason why GM crops are more expensive for farmers than traditional crops.
