1、高三英语阅读理解专题训练答案高三英语阅读理解专题训练答案一、高中英语阅读理解1阅读理解 Chinese scientists recently have produced two monkeys with the same gene, Zhong Zhong and Hua Hua, using the same technique that gave us Dolly the sheep. These monkeys are not actually the first primates(灵长类)to be cloned. Another one named Tetra was produc
2、ed in the late 1990s by embryo(胚胎)splitting, the division of an early-stage embryo into two or four separate cells to make clones. By contrast, they were each made by replacing an egg cell nucleus(原子核)with DNA from a differentiated body cell. This Dolly method, known as somatic cell nuclear transfer
3、(SCNT), can create more clones and allows researchers greater control over the edits they make to the DNA. Success came from adopting several new techniques. These included a new type of microscopy to better view the cells during handling or using several materials that encourage cell reprogramming,
4、 which hadnt been tried before on primates. Still, the research process proved difficult, and many attempts by the team failed. Just two healthy baby monkeys born from more than 60 tested mothers. This leads to many researchers pouring water on the idea that the teams results bring scientists closer
5、 to cloning humans. They thought this work is not a stepping stone to establishing methods for obtaining live born human clones. Instead, this clearly remains a very foolish thing to attempt, it would be far too inefficient, far too unsafe, and it is also pointless. But the scientists involved empha
6、size that this is not their goal. There is now no barrier for cloning primate species, thus cloning humans is closer to reality. However, their research purpose is entirely for producing non-human primate models for human diseases; they absolutely have no intention, and society will not permit this
7、work to be extended to humans. Despite limitations, they treat this breakthrough a novel model system for scientists studying human biology and disease.(1)What do we know about the technology called SCNT? A.It created the first two primates.B.It may contribute to editing the DNAC.It can divide an ea
8、rly-stage embryo into several cells.D.It produced two cloned monkeys with different genes.(2)What does the author mean by “pouring water on the idea” in paragraph 2? A.Keeping a hot topic of it.B.Having a low opinion of it.C.Attaching no importance to it.D.Adding supportive evidence to it.(3)What is
9、 the scientists purpose to clone these monkeys? A.To help with the study of human diseases.B.To serve as a stepping stone to their reputation.C.To prepare for their research on human cloning.D.To raise money for holding an exhibition of novels.(4)What can we infer from the passage? A.New techniques
10、seem to be pointless.B.Cloning humans is already on its way.C.Society wont agree to clone another monkey.D.The success rate of cloning a monkey was not high.【答案】(1)B(2)B(3)A(4)D 【解析】【分析】本文是一篇说明文,科学家们利用高科技克隆猴子帮助研究人类疾病。(1)考查细节理解。根据第一段中的“This Dolly method, known as somatic cell nuclear transfer(SCNT),

15、理,选出正确答案。2阅读理解 Paying a higher price than usual for a ticket to see a film in 3D is the annoyance of many a cinema-goers life. But there may be a benefit to doing so, as a study has found that 3D films exercise the brain and improve short-term functioning in a similar way to brain-training tests. Th
16、e research found that people who watched a movie in 3D improved cognitive (认知) skills, compared to those who watched it in 2D. The research was led by neuroscientist(神经学家) Dr Patrick Fagan from Goldsmiths University in London. More than 100 people took part in the experiment, where participants watc
17、hed Disney film Big Hero 6 in either standard format or RealD 3D. They also carried out a brain-training-style test before and after seeing a section from the film. The test covered memory, reaction times and cognitive function and the results were compared later. According to the research, which wa
18、s carried out in partnership with science group Thrill Laboratory, participants experienced a 23 percent increase in cognitive processing, as well as an 11 percent increase in reaction times. Dr Fagan said that the results showed enough of an improvement in brain function to suggest that 3D could pl
19、ay a part in improving brain power in the future. These findings are more significant than you might think, he said. It is a fact that people are living longer and there is a noticeable decline in cognitive brain function in old age which can worsen future quality of life. There has never been a bet
20、ter time to look at ways to improve brain function. The initial results of this study show that 3D films may potentially play a role in slowing this decline. A second part of the experiment involved those watching the film being fitted with headsets that scanned brain activity and this too showed he
21、ightened (加强的) activity when watching 3D. According to the results, participants were seven percent more engaged with what they were watching, adding to argument that 3D movies are more like watching real-lifesomething Professor Brendan Walker from Thrill Laboratory agreed with. As Professor Brendan

27、alize what had happened. Three days had passed and Rita seemed to get weaker and weaker. The rain had stopped. However, the sky was still cloudy, and it was so dark that I couldnt see the buildings even across the road. I took a pressure reading from the weather station: 947mb, which let me know exa
28、ctly where I wasin the eye of the storm. There were rains and winds still, but not oppressive (难以忍受的)anymore. There was still no power, hot water or food. Besides, I didnt sleep well for all these days, but I felt more relaxed since the weather report said Rita was leaving. Whats more, I was luckier
29、 than those people who had lost their homes or even worse, lost their lives because of Rita. As I travelled further to the west, going after the storm, the damage along the way became less severe. I arrived in Houston after a tricky journey with my fuel supplies almost all gone. However, I came acro
30、ss another storm chaser (追逐者) who had 45 gallons of petrol. He helped me and we shared our working experience these days. With a complete stroke of luck I found a run-down hotel that allowed me to have a room overnight before the midnight. Although there was no running water, no power and no air con
31、ditioning, I curled up into a corner and fell asleep quickly. I woke up the next morning, and what a change! The sky was blue and cars were moving around. Sirens could be heard as convoys (护航队) of emergency managements started to head west towards where I had come from. The storm had stopped and I could go home. I gave all my remaining supplies to other people at the hotel and headed towards the airport. Houston Airport was not damaged, so I took my flight and drank my first h
