Irradiation of other meats, such as beef and lamb, is being reviewed. Fe

8、deral approval does not require that industry adopt the process, and few food processors presently offer irradiated products.Market studies have shown that many consumers are afraid that eating irradiated foods may cause cancer, despite scientific studies that prove the safety of treated foods. Some

9、 people argue that more severe government inspection, higher food safety standards, and more careful-preparation practices by consumers are all that is needed to ensure that food is safe. Consequently, companies currently see no need to spend millions of dollars outfitting processing plants with the

10、 equipment necessary for a process that very few shoppers are in favor of.All supermarkets that sell irradiated food must label the food either directly on the packaging, or, in the case of bulk items like fruits and vegetables, by placing a sign nearby. There is no requirement for the labeling of i

11、rradiated food served by chain restaurants or hospitals that buy directly from distributors, nor any regulations for products that contain irradiated ingredients.Presently, the FDA allows food to be treated with three types of radiationgamma rays, high-energy electrons, and X raysand sets limits on

12、doses, depending on the type of food. The principle is that the dose to be used for a certain type of food should not exceed the amount that is sufficient to kill most harmful insects and bacteria present in it. Different types of food, because of their molecular compositions, may require different

13、doses of radiation.（分数：7.00）(1).According to the passage, killing insects and bacteria present in foods by irradiating is not completely approved by the US government. A. Right B. Wrong C.

Check out the io Personal Digital Pen launched by Logitech: Its a magic pen that can store everything you write and transfer it to your computer. And you dont have to lug a hand held device a

18、long with you for it to work.2. Logitechs technology works like this: The pen writes normally, using normal ballpoint pen ink. But while you are writing, a tiny camera inside the pen is also taking 100 snapshots per second of what you are doing, mapping your writing via a patchwork of minute dots pr

19、inted on the paper. All this informationthe movement of your pen on the paper, basicallyis then stored digitally inside the pen, whether you are writing notes or drawing complex diagrams. You can store up to 40 pages worth of doodles in the pens memory. As far as you are concerned, you are just usin

20、g a normal pen.3. It is only when you drop the pen into its PC-connected cradle that the fun begins. Special software on your PC will figure out what you have done, and begin to download any documents you have written since the last time it was there. Depending on whether you have ticked certain box

21、es on the special notepad, it can also tell whether the document is destined to be an e-mail, a “to do“ task, or a diagram to be inserted into a word processing document. Once the documents are downloaded you can view them, print them out or convert them to other formats.4. The io Personal Digital P

30、led on two reasonable theories related to baby talk. One states that a young childs brain needs time to master language, in the same way that it does to master other abilities such as physical movement. The second theory states that a childs vocabulary level is the key factor. According to this theo

31、ry, some key steps have to occur in a logical sequence before sentence formation occurs. Childrens mathematical knowledge develops in the same way.In 2007, researchers at Harvard University, who were studying the two theories, found a clever way to test them. More than 20,000 internationally adopted

32、 children enter the US each year. Many of them no longer hear their birth language after they arrive, and they must learn English more or less the same way infants dothat is, by listening and by trial and error. International adoptees dont take classes or use a dictionary when they are learning thei

33、r new tongue and most of them dont have a well developed first language. All of these factors make them an ideal population in which to test these competing hypotheses about how language is learned.Neuroscientists Jesse Snedeker, Joy Geren and Carissa Shafto studied the language development of 27 ch

34、ildren adopted from China between the ages of two and five years. These children began learning English at an older age than US natives and had more mature brains with which to tackle the task. Even so, just as with American born infants, their first English sentences consisted of single words and w

35、ere largely bereft (缺乏的) of function words, word endings and verbs. The adoptees then went through the same stages as typical American born children, though at a faster clip. The adoptees and native children started combing words in sentences when their vocabulary reached the same sizes, further sug

36、gesting that what matter is not how old you are or how mature your brain is, but the number of words you know.This findingthat having more mature brains did not help the adoptees avoid the toddler-talk stagesuggests that babies speak in baby talk not because they have baby brains, but because they h

37、ave only just started learning and need time to gain enough vocabulary to be able to expand their conversations. Before long, the one-word stage will give way to the two-word stage and so on. Learning how to chat like an adult is a gradual process.But this potential answer also raises an even older

38、and more difficult question. Adult immigrants who learn a second language rarely acheive the same proficiency in a foreign language as the average child raised as a native speaker. Researchers have long suspected there is a “critical period“ for language development, after which it cannot proceed wi

39、th full success to fluency. Yet we still do not understand this critical period or know why it ends.（分数：15.00）(1).What is the writers main purpose in Paragraph 2? A. To reject the view that adopted children need two languages. B. To argue that culture affects the way children learn a language. C. To

40、 give reasons why adopted children were used in the study. D. To justify a particular approach to language learning.（分数：3.00）A.B.C.D.(2).Snedeker, Geren and Shafto based their study on children who _. A. were finding it difficult to learn English B. were learning English at a later age than US child

41、ren C. had come from a number of language backgrounds D. had taken English lessons in China（分数：3.00）A.B.C.D.(3).What aspect of the adopted childrens language development differed from that of US born children? A. The rate at which they acquired language. B. Their first words. C. The way they learnt

42、English. D. The point at which they started producing sentences.（分数：3.00）A.B.C.D.(4).What does the Harvard finding show? A. Not all toddlers use babytalk. B. Some children need more conversation than others. C. Language learning takes place in ordered steps. D. Not all brains work in the same way.（分

43、数：3.00）A.B.C.D.(5).When the writer says “critical period“, he means a period when _. A. studies produce useful results B. adults need to be taught like children C. language learning takes place effectively D. immigrants want to learn another language（分数：3.00）A.B.C.D.六、B第二篇/B(总题数：1，分数：15.00)DNA Finge

44、rprintingDNA is the genetic material found within the cell nuclei of all living things. In mammals (哺乳动物) the strands of DNA are grouped into structures called chromosomes (染色体). With the exception of identical twins, the complete DNA of each individual is unique.DNA fingerprinting is sometimes call

45、ed DNA typing. It is a method of identification that compares bits of DNA. A DNA fingerprint is constructed by first drawing out a DNA sample from body tissue or fluid such as hair, blood, or saliva (唾液). The sample is then segmented using enzymes (酶), and the segments are arranged by size. The segm

46、ents are marked with probes and exposed on X-ray film, where they form a pattern of black bars the DNA fingerprint. If the DNA fingerprints produced from two different samples match, the two samples probably came from the same person.DNA fingerprinting was first developed as an identification techni

47、que in 1985. Originally used to detect the presence of genetic diseases, it soon came to be used in criminal investigations and legal affairs. The first criminal conviction based on DNA evidence in the United States occurred in 1988. In criminal investigations, DNA fingerprints derived from evidence

48、 collected at the crime scene are compared to the DNA fingerprints of suspects. Generally, courts have accepted the reliability of DNA testing and admitted DNA test results into evidence. However, DNA fingerprinting is controversial in a number of areas: the accuracy of the results, the cost of testing, and the possibl
