23、；那个巨大的蛤蜊半掩在珊瑚礁中等着有什么东西游过来，游到它那宽厚的绿嘴唇中去。然后，有两条灰色的礁鲨，每条大约有1.5米长，突然从珊瑚后边游了出来。我告诉自己它们并不危险，但是这样一点也不能抑制我那怕得要死的心情！水很浅，但是到了珊瑚礁的尽头，就有一个陡坡，一直下降到满是沙子的海底。这是边界的标志。我游过珊瑚礁的边沿，浮在上面往下看海底的时候，我认为我还是非常勇敢的。我的心急剧地跳动着在这样深邃而清澈的海水中，我感觉我彻底曝光了。这个水底下的世界是多么美妙，多么漫无边际！ 而我在这个海洋的世界中又是多么渺小！ reflectvi.思考vt.映射；反射；思考(教材P24)Im sitting i

One of the challenges, however, is making products that are valuable enough to cover the high costs of extracting(提取) the carbon dioxide.There is already a significant market f

56、or CO2 and products made from it, most obviously fertilizer and fuels. This process of treating the gas as an original material rather than a waste product is known as carbon dioxide use (CDU) and usually starts by extracting CO2 from industrial gases. Extracting CO2 directly from the air can be a c

57、omplex process. As CO2 represents just 0.04% of the atmosphere, you have to treat very large amounts of air just to produce even modest quantities of the gas. However, several companies have managed to design chemical processes to produce enough industrial CO2 which is economically practicable. The

58、new research from George Washington University finds a way to directly extract CO2 from the air and turn it into carbon nanofibres(纳米纤维). The researchers claim their new producing method is much cheaper than existing techniques. Could it become so widely used that it significantly reduces atmospheri

59、c CO2 levels? Current production of carbon nanofibres is around 500 tonnes a year and predicted to augment largely. But this is still far from the hundreds of millions of tonnes that would be needed to deal with greenhouse gases.Sadly its most unlikely that the interesting breakthrough will be scale

60、d up to limit climate change in the way that has been claimed. We believe that due to the size of the potential market, carbon nanofibres alone will not be able to make a significant impact on CO2 emission(排放). However, many new technologies and materials start with a small area before moving into m

61、ore mainstream uses. And perhaps this could be the case for direct air extracting nanofibres. After all, change has to start somewhere.【解题导语】本文是一篇说明文。科学家一直在尝试将二氧化碳转化为有用的产品，本文介绍了此方面的一些进展和成果。1What can we know from Paragraph 2?

A jellyfish has no head, brain, heart, eyes, or ears.Fossil evidence of these creatures dates back to over 65

65、0 million years ago, perhaps earlier than dinosaurs. With so many kinds of jellyfish floating about, there must be variety in the appearance of their body parts.

When the jellyfish comes in contact with potential danger, the cells of the nerve net respond by shooting out many tentac

68、les.Although the jellyfish does not have sensory organs, it does possess tiny simple sensory structures. Their special structures in the body can react to light. Thus the jellyfish, though lacking a brain and eyes, can respond to sunlight shining through the water. It should be noted that, although

69、it can perceive light, without eyes it cannot see images.Jellyfish, because of their stinging(蜇人的) tentacles, can be dangerous to humans. Of the more than 2，000 species, roughly 70 are thought to be potentially dangerous to humans. The stings of some of these can even be deadly to humans, and may le
