2017年6月大学英语六级考试真题（第三套）Part I Writing （30 minutes）Directions: Suppose you are asked to give advice on whether to major in science or humanities at college, write an essay to state your opinion. You are required to write at least 150 words but no more than 200 words.Part II Listening Comprehension （30 minutes）（说明：由于2017年6月六级考试全国共考了2套听力，本套真题听力与前2套内容完全一样，只是顺序不一样，因此在本套真题中不再重复出现）Part III Reading Comprehension （40 minutes）Section ADirections: In this section, there is a passage with ten blanks. You are required to select one word for each blank from a list of choices given in a word bank following the passage. Read the passage through carefully before making your choices. Each choice in the bank is identified by a letter. Please mark the corresponding letter for each item on Answer Sheet 2 with a single line through the centre. You may not use any of the words in the bank more than once.Half of your brain stays alert and prepared for danger when you sleep in a new place, a study has revealed. This phenomenon is often 26 to as the “first-night-effect”. Researchers from Brown University found that a network in the left hemisphere of the brain “remained more active” than the network in the right side of the brain. Playing sounds into the right ears （stimulating the left hemisphere） of 27 was more likely to wake them up than if the noises were played into their left ear.It was 28 observed that the brain was more active during deep sleep. When the researchers repeated the laboratory experiment on the second and third nights they found the left hemisphere could not be stimulated in the same way during deep sleep. The researchers explained that the study demonstrated “when we are in a 29 environment, the brain partly remains alert so that humans can defend themselves against any 30 danger.”The researchers believe this is the first time that the “first-night-effect” of different brain states has been 31 in humans. It isnt, however, the first time it has ever been seen. Some animal 32 also display this phenomenon. For example, dolphins, as well as other 33 animals shut down one hemisphere of the brain when they go to sleep. A previous study noted that dolphins always 34 control their breathing. Without keeping the brain active while sleeping, they would probably down. But, as the human study suggest, another reason for dolphins keeping their eyes open during sleep is that they can look out for 35 while asleep. It also keeps their physiological processes working.

Each statement contains information given in one of the paragraphs. Identify the paragraph from which the information is derived. You may choose a paragraph more than once. Each paragraph is marked with a letter. Answer the questions by marking the corresponding letter on Answer Sheet 2.The Price of Oil and the Price of CarbonAFossil fuel prices are likely to stay “low for long”. Notwithstanding important recent progress in developing renewable fuel sources, low fossil fuel prices could discourage further innovation in, and adoption of, cleaner energy technologies. The result would be higher emissions of carbon dioxide and other greenhouse gases.BPolicymakers should not allow low energy prices to derail the clean energy transition. Action to restore appropriate price incentives, notably through corrective carbon pricing, is urgently needed to lower the risk of irreversible and potentially devastating effects of climate change. That approach also offers fiscal benefits.COil prices have dropped by over 60 percent since June 2014. A commonly held view in the oil industry is that “the best cure for low oil prices is low oil prices”. The reasoning behind this saying is that low oil prices discourage investment in new production capacity, eventually shifting the oil supply curve backward and bringing prices back up as existing oil fieldswhich can be tapped at relatively low marginal costare depleted. In fact, in line with past experience, capital expenditure in the oil sector has dropped sharply in many producing countries, including the United States. The dynamic adjustment to low oil prices may, however, be different this time around.DOil prices are expected to remain lower for longer. The advent of new technologies has added about 4.2 million barrels per day to the crude oil market, contributing to a global over-supply. In addition, other factors are putting downward pressure on oil prices: change in the strategic behavior of the Organization of P
