2017年6月英语六级真题(第三套)
Part IWriting(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 A
Directions:
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 arei n 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 isn’t, 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 process
es working.

Section B
Directions:
In this section, you are going to read a passage with ten statements attached
to it. 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 Carbon
[A] Fossil 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.
[B] Policymakers 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.
[C] Oil 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 fields—which can be tapped at relatively low marginal cost—are 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.
[D] Oil 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 Petroleum Exporting Countries, the
projected increase in Iranian exports, the scaling-down of global demand ( especially from
emerging markets), the long-term drop in petroleum consumption in the United States, and
some displacement of oil by substitutes. These likely persistent forces, like the growth of
shale
( 页 岩 ), point to a “low for long” scenario. Futures markets, which show only a
modest recovery of prices to around $60 a barrel by 2019, support this view.
[E] Natural gas and coal—also fossil fuels—have similarly seen price declines that look
to be long-lived. Coal and natural gas are mainly used for electricity generation, whereas
oil is used mostly to power transportation, yet the prices of all these energy sources are
linked. The North American shale gas boom has resulted in record low prices there. The
recent discovery of the giant Zohr gas field off the Egyptian coast will eventually have
impact on pricing in the Mediterranean region and Europe, and there is significant
development potential in many other places, notably Argentina. Coal prices also are low,
owing to over-supply and the scaling down of demand, especially from China, which burns
half of the world’s coal.
[F] Technological innovations have unleashed the power of renewables such as wind, hydro,
solar, and
geothermal
(地热). Even Africa and the Middle East, home to economies that are
heavily dependent on fossil fuel exports, have enormous potential to develop renewables.
For example, the United Arab Emirates has endorsed an ambitious target to draw 24% of its
primary energy consumption from renewable sources by 2021.
[G] Progress in the development of renewables could be fragile, however, if fossil fuel
prices remain low for long. Renewables account for only a small share of global primary
energy consumption, which is still dominated by fossil fuels—30% each for coal and oil,
25% for natural gas. But renewable energy will have to displace fossil fuels to a much
greater extent in the future to avoid unacceptable climate risks.
