下列选项中,对课文理解不恰当的一项是( )
A.《项链》构思巧妙,一波三折,看似意料之外的结局,但经过作者对玛蒂尔德性格的刻画和巧妙的伏笔铺垫,一切又都显得在情理之中了。
B.《祝福》采用了插叙的手法,在叙述中插入了祥林嫂在一片祝福声中寂然死去,而鲁四爷却大骂她为“谬种”的情节,形成一股浓厚的悲剧氛围,同时也造成了一系列悬念:祥林嫂是什么人?为什么境遇如此凄惨?
C.在《巩乃斯的马》中,“马”作为核心形象引起了作者对世界的思考,文中的马的形象寄托了作者对不受羁绊的自由的生命境界的追求。
D.莫泊桑笔下的玛蒂尔德是个个性丰满的人物,她虚荣但不虚伪,在生活的无奈之下也不失尊严,勇敢担当,所以人们讨论这一形象时既有讽刺,也有同情;既有批评,也有肯定。

B.卵细胞不能受精,性激素正常分泌
C.卵细胞不能形成,性激素正常分泌
D.卵细胞不能受精,性激素不能分泌
五.任务型阅读(10分) Could your cellphone give you cancer? Whether it could or not, some people are worrying about the possibility that phones, powerlines and wi-fi (路由器) could be responsible for a range of illnesses, from rashes to brain tumours. For example, Camilla Rees, 48, a former investment banker in the US, moved out of her apartment in San Francisco because of the radiation coming from next door. Rees told the Los Angeles Times that when her neighbors moved in and installed a wi-fi router she lost her ability to think clearly. “I would wake up dizzy in the morning. I’d fall to the floor. I had to leave to escape that nightmare,” she said. Since then, she’s been on a campaign against low-level electromagnetic fields, or EMFs(低频电磁场). And she’s not alone. Millions of people say they suffer from headaches, depression, nausea and rashes when they’re too close to cellphones or other sources of EMFs. Although the World Health Organization has officially declared that EMFs seem to pose little threat, governments are still concerned. In fact, last April, the European Parliament called for countries to take steps to reduce exposure to EMFs. The city of San Francisco and the state of Maine are currently considering requiring cancer-warning labels on cellphones. If these fears are reasonable, then perhaps we should all be worried about the amount of time we spend talking on our phones or plugging into wi-fi hotpots. Some say there is evidence to support the growing anxieties. David Carpenter, a professor of environmental health sciences at the University at Albany, in New York, thinks there’s a greater than 95% chance that power lines can cause childhood leukemia. Also there’s a greater than 90% chance that cellphones can cause brain tumours. But others believe these concerns are unreasonable paranoia (猜疑). Dr Martha Linet, the head of radiation epidemiology at the US National Cancer Institute, has looked at the same research as Carpenter but has reached a different conclusion. “I don’t support warning labels for cellphones,” said Linet. “We don't have the evidence that there’s much danger.” Studies so far suggest a weak connection between EMFs and illness — so weak that it might not exist at all. A multinational investigation of cellphones and brain cancer, in 13 countries outside the US, has been underway for several years. It’s funded in part by the European Union, in part by a cellphone industry group. According to Robert Park, a professor of physics at the University of Maryland in the US, the magnetic waves aren’t nearly powerful enough to break apart DNA, which is how known threats, such as UV rays and X-rays, cause cancer. Perhaps it’s just psychological. Some experts find that the electro-sensitivity syndrome seems to be similar to chemical sensitivity syndrome, which is a condition that’s considered to be psychological. Whether EMFs are harmful or not, a break in the countryside, without the cellphone, would probably be good for all of us.
