If every public interaction were filmed, would the world be a better place? Common sense suggests it would, and to some extent, we already live in such a world, with closed-circuit television cameras everywhere and smart phones in every pocket.

However, the routine filming of everyday life is about to go to the next level. A number of countries are rolling out body cams for police officers and other public-facing agencies such as school.

Private citizens are getting in on the act too: cyclists increasingly wear headcams as an insurance against aggressive drivers. As camera technology gets smaller and cheaper, it isn?t hard to foresee a future where we?re all filming everything all the time, in every direction. Would that be a good thing?

The available evidence suggests that it discourages behavior such as police brutality. Another upside is that it would be harder to get away with crimes or to escape blame for accidents. But a world on camera could have subtle negative effects. The flood of data we pour into the hands of Google, Facebook and others has already proved a mixed blessing. Those companies would no doubt be willing to upload and store our body-cam data for free,

probably with the assistance of machine learning algorithms(算法)---but at what cost to privacy and freedom of choice? Body-cam data could also create a legal mine field. Disputes over the validity and interpretation of police footage(执法镜头)have already surfaced.

Eventually, events not caught on camera could be treated as if they didn?t happen, like a tree falling in the forest. Alternatively, footage could be faked or doctored to escape blame or incriminate others.

Of course, there?s always the argument that if you?re not doing anything wrong, you have nothing to fear. But most people have done something embarrassing, or even illegal, that they regret and would prefer hadn?t been caught on film. People already inspect their social media feeds---or avoid doing anything inadequate in public---for fear of damaging their reputation. Would widespread application of body cams have a further frightening effect on our freedom? The always-on-camera world could even threaten some of the natures that make us human. We are natural gossips and backbiters, and while those might not be desirable behavior, they oil the wheels of our social interactions. Once people assume they are being filmed, they are likely to shut up. We are nowhere near that point yet where everyone will feel they need one as an

江苏省南京市、盐城市2018届高三第一次模拟考试 英语 insurance policy, but we should think hard about whether we really want to say lights, body cam, action.

A so-called “smart drug” intended to improve cognitiv（e to protect the brain from altitude sickness.

认知的）performance also seems

Even more people are visiting high-altitude sites for work, sport, religious pilgrimages and military can lead to cognitive effects, including memory loss and attention difficulties.

There?s little you can do to prevent these symptoms other than acclimatize—but this takes time and doesn?t always work. A drug called oxiracetam might be the answer.

ShengLi Hu at the Third Military Medical University, Chongqing, China and her colleagues studied the performance of male military personnel at altitude. All lived in towns around 1800 meters above sea level. During the study, they spent eight days at this altitude and then climbed for three days to reach 4000 meters, where they stayed for up to a month.

Twenty participants took oxriacetam three times a day for the first 15 days of the study, while another 20 received no intervention. The man did tests of attention and memory at the start and end of the study and 20 days in, by which time they had been at 4000 meters for nine days.

While all the participants experienced a drop in cognitive ability at 4000 meters, those who took oxiracetam showed a much smaller decline than the control group.

Blood flow measurements indicated that at high altitude, parts of the brain?s cerebral circulatory system contracted and dilated（扩张）in a way that promoted blood flow to the brain stem. This isn?t surprising, since the brain stem plays a critical role in the maintenance of basic vital signs.

The team also found that the brain stem received blood at the expense of areas responsible for more advanced cognitive functions. But in people who took oxiracetam, more arteries dilated,

江苏省南京市、盐城市2018届高三第一次模拟考试 英语 so blood flow throughout the brain rose. This may be how the drug seems to lessen cognitive problems liked with low oxygen.

It isn?t yet known whether diverting blood in this way could have negative effects in the long run.

“The results are striking and imply that oxiracetam may be beneficial for helping to relieve cognitive deficits caused by altitude,” says Timothy Hales at the University of Dundee, UK.

Oxiracetam is not licensed for medical use globally, but it is known to be a mild stimulant, says Hales. “Coca leaves have been used by native Andeans for centuries to overcome altitude sickness and this is attributed to their modest cocaine content. So perhaps it is not surprising that benefit can be derived from another, though mild, stimulant.”

61. The underlined word “acclimatize” in Paragraph 3 is closest in meaning to A. adapt

B. interact

C. exist

D. object

62. What does the experiment done in China reveal?

A. The higher altitude you are at, the slower your brain will be. B. At 4000 meters, the two subject groups show no difference. C. Memory tests are beneficial to relieving attention difficulties. D. “Smart drug” largely counters negative effects of altitude sickness. 63. According to the passage, the root cause of the cognitive effects lies in A. physical tiredness

C. cognitive training

64. What is the best title for the passage?

A. Fight high anxiety C. Keep sharp at altitude

. . B. low oxygen content D. extreme high altitude B. Oxiacetam—a magic drug D. Problems on high-altitude sites

If you read The Fault in our stars only to find a young adult romance of Hazel Grace and Augustus Waters, then you definitely underestimate the power of sophisticated symbolism, emotions, and literature John Green offers. I remember someone saying “You don’t read a great book; it reads you.” The fault in our stars is one of those books. It gives you the concept of what cancers are like, of how children in particular fight them, reveals and reminds you of your first love in life, always the youngest and the most innocent. I will resist my urge to tell you the plot and spoil the whole story, but I promise you every single page here is worth a great deal of excitement, humor and a bunch of other stuff listed down here which I think are interesting.

The book gives lives to where we find deaths. The joy of living comes in when terminal

江苏省南京市、盐城市2018届高三第一次模拟考试 英语 cancer is nothing more than just, “a side effect of dying”, when you can laugh in the misfortunes of disease and say “ I?m on a rollercoaster that only goes up, my friend.” The fault in our stars, however, stars with Hazel?s “depression” like many of us starts a new day. Thus, Hazel?s mother wants her cancer-stricken daughter to have a life, putting her in the Support Group. Later on, Issac and Augustus give her hope and something to believe in. The friendship tied by the shared intellectual curiosity and dreams. The story is so carefully plotted that even though Hazel doesn?t go to school like other kids, her life is so in touch with ours. Everyone in a while will feel as if everything goes wrong, that it sucks at being what it?s supposed to be. Bad grades, getting dumped, or even having a terminal disease. “The pain demands to be felt.” But after all, how long should it take us to give sufferings a break is subject to be viewed personally, since it would determine whether or not we become a type of Peter Van Houten, Hazel?s favorite writer in the novel.

John Green also cares about your dreams and ambitions. As you read through chapters, especially toward the end, you will find out Hazel and Augustus have widely different ideas of what they think is a “good life.” Here I find a reflection of my soul in Augustus?s, with all his desire to leave a mark on the world. Such a guy he is seeking for glories and meanings of life, fearing most oblivion. Others may find themselves, in contrast, caring not about recognition. They are like Hazel Grace, seeing heroism as an act of noticing and loving and sharing. Both ideas are beautiful and proofed to be fearless to be together despite any mental or physical challenges lying on their way to the pursuit of happiness.

① “Apparently, the world is not a wish-granting factory.” The book embraces the restless, innocent desires of young minds.

② Would you care for a trip to Amsterdam

when you?re at the 4th stage of cancer to find out what happens after the end of your favorite book? Would you dare to love the dying, to be okay to love when you?re dying, or to forgive yourself for hurting those who love you in case you die? ③_ In the book, you will find

John Green mentions about how “some infinities are greater than other infinities,” which means, I think, infinities can be defined, expanded and shrunk. _ ④ Infinities are created

by taking chances, and if we fail while doing so, then the fault is simply in out stars, not ourselves.
