在职申硕英语考试易错题(2019/5/7)
In recent years a new farming revolution has begun, one that involves the {{U}} (61) {{/U}} of life at a fundamental level--the gene. The study of genetics has {{U}} (62) {{/U}} a new industry called biotechnology.As the name suggests, It {{U}} (63) {{/U}} biology and modern technology through such techniques as genetic engineering. Some of the new biotech companies specialize in agriculture and are working feverishly to {{U}} (64) {{/U}} seeds that give a high yield, that {{U}} (65) {{/U}} diseases, drought and frost, and that reduce the need for {{U}} (66) {{/U}} chemicals. If such goals could be achieved, it would be most {{U}} (67) {{/U}}.But some have raised concerns about genetically engineered crops.
In nature, genetic diversity is created within certain {{U}} (68) {{/U}}.A、rose can be crossed with a different kind of rose, but a rose will never cross with a potato. Genetic engineering, {{U}} (69) {{/U}} usually involves taking genes from one species and inserting them into another {{U}} (70) {{/U}} to transfer a desired characteristiC、This could mean, for example, selecting a gene which leads to the production of a chemical with anti-freeze {{U}} (71) {{/U}} from an artic fish, and inserting it into a potato or strawberry to make it frost-resistant. {{U}} (72) {{/U}}, then, biotechnology allows humans to {{U}} (73) {{/U}} the genetic wails that separate species.
Like the green revolution, {{U}} (74) {{/U}} some call the gene revolution contributes to the problem of genetic uniformity--some say even more so {{U}} (75) {{/U}} geneticists can employ techniques such as cloning and {{U}} (76) {{/U}} culture (培养), processes that produce perfectly {{U}} (77) {{/U}} copies.Concerns about the erosion of biodiversity, therefore, remain. Genetically altered plants, however, raise new {{U}} (78) {{/U}}, such as the effects that they may have on us and the environment. "We are flying blindly into a new {{U}} (79) {{/U}} of agricultural biotechnology with high hopes, few constraints, and little idea of the potential {{U}} (80) {{/U}} " said science writer Jeremy Rifkin.

If those "{{U}}mad moments{{/U}}"— when you can’t recall what your friend has told you or where you left your keys—are becoming more frequent, mental exercises and a healthy brain diet may help.
Just as bodies require more maintenance with the passing years, so do brains, which scientists now know show signs of aging as early as the 20s and 30s. "Brain aging starts at a very young age, younger than any of us have imagined and these processes continue gradually over the years," saidDr. Gary Small, the director of theCenter onAging at the University ofCalifornia, LosAngeles. "I’m convinced that it is never too early to get started on a mental or brain-fitness program," he addeD、
In his book, "The MemoryBible," the 51-year-old neuroscientist lists what he refers to as the 10 commandments for keeping the brain young. They include training memory, building skills, minimizing stress, mental exercises, brain food and a healthy lifestyle. It’s a game plan for keeping brain cells sparking and neural networks in tip-top shape.
"Misplacing your keys a couple of times doesn’t mean you should start labeling your cabinets. Memory loss is not an inevitable consequence of aging. Our brains can fight back," he saiD、
Small provides the weapons for a full-scale attack.According to him, simple memory tests give an indication of what you are up against and tools such as look, snap and connect are designed to make sure that important things such as names and dates are never forgotten. "So if you want to learn names and faces, for example, you meet Mrs.Beatty and you notice a distinguishing facial feature, maybe a prominent eyebrow," said Small. "You associate the first thing that comes to minD、 I think of the actor WarrenBeatty so I create a mental snapshot of WarrenBeatty kissing her brow. "
Small admits it may sound a bit strange but he says it works. " Mental exercises could be anything from doing crossword puzzles and writing with your left hand if you are right handed or learning a language. It could be anything that is fun that people enjoy doing", he addeD、
He also recommends physical exercise, a low-fat diet and eating foods rich in omega-3 fatty acids, such as fish, walnuts andBrazil nuts, and fruits and vegetables high in antioxidants (抗氧化剂) including blueberries and onions in addition to reducing stress.
5题:{{B}}Passage Two{{/B}}
In the fifth paragraph, the author mainly ______.A.provides us with the weapons for attacking others
B.introduces the tools that help us fight against memory loss
C.tells us about the important things we should never forget
D.explains the facial features useful for us to remember people
