amounts of energy intelligently, even a large, messy weather system approaching from the future
could be eased.
While somewhat fascinating, Miles’ explanation does little to explain how he is able to

，
his company website, which claimed that his technology used “electromagnetic scalar waves”which scientists say don’t even exist.
The Australian Competition and Consumer Commission (ACCC) has warned people
against doing business with him, but the Australian inventor claims the ACCC is only trying to
defame him and his company, as in reality they are success based - if it doesn’t rain, they don’t get paid.
“Consumers signed the agreement that if by the end of June they receive 100mm, they
pay $50,000, if they only receive 50mm, they would only pay $25,000. Anything under half，we
don’t want to be paid,” Miles said of a handf
ul of Wimmera farmers who agreed to take him up on
his offer to deliver rain.
Believe it or not, one of the farmers who paid David Miles for his so-called
rain-making capabilities told ABC Radio that he was quite happy with the results.
56. David Miles claims to be capable of ________.
A. influencing the weather system
B. predicting the future events
C. reducing the atmospheric temperature
D. easing the gravitational energy
57. ACCC issued warning against doing business with Miles because________.
A. he charged too much for the services provided
B. there was no solid science to hack up his technology
C. his practice was a threat to national security interest
D. he didn’t officially patent his technology with ACCC
58. According to Miles，how much will be paid if the farmers receive 15mm of rain?
A. $50,000.
B. $25,000.
C. $12,500.
D. $0.
59. What can be inferred from the passage?

(C)
How and why, roughly 2 million years ago, early human ancestors evolved large brains
and began fashioning relatively advanced stone tools, is one of the great mysteries of evolution.
Some researchers argue these changes were brought about by the invention of cooking. They point
out that our bite weakened around the same time as our larger brains evolved, and that it takes less energy to absorb nutrients from cooked food. As a result, once they had mastered the art, early
chefs could invest less in their digestive systems and thus invest the resulting energy savings in
building larger brains capable of complex thought. There is, however, a problem with the cooking theory. Most archaeologists (考古学家）believe the evidence of controlled fire stretches back no
more than 790,000 years.
Roger Summons of the Massachusetts Institute of Technology has a solution. Together
with his team, he analyzed 1.7 million-year-old sand-stones that formed in an ancient river at Olduvai Gorge in Tanzania. The region is famous for the large number of human fossils (化石)
that have been discovered there, alongside an impressive assembly of stone tools. The sand-stones themselves have previously yielded some of the world’s earliest complex hand axes —large
tear-drop-shaped stone tools that are associated with Homo erectus (直立人) . Creating an axe by repeatedly knocking thin pieces off a raw stone in order to create two sharp cutting edges requires
a significant amount of planning. Their appearance is therefore thought to mark an important moment in intellectual evolution. Trapped inside the Olduvai sand-stones, the researchers found distinctive but unusual biological molecules（分子）that are often interpreted as biomarkers for
heat-tolerant bacteria. Some of these live in water between 85°C and 95°C. The molecules’ presence suggests that an ancient river within the Gorge was once fed by one or more hot springs.
Dr. Summons and his colleagues say the hot springs would have provided a convenient “pre-fire” means of cooking food. In New Zealand，the Maori have traditionally cooked food in
hot springs, either by lowering it into the boiling water or by digging a hole in the hot earth. Similar methods exist in Japan and Iceland, so it is plausible, if difficult to prove, that early humans might have used hot springs to cook meat and roots. Richard Wrangham, who devised the cooking theory, is fascinated by the idea. Nonetheless, fire would have offered a distinct advantage
to humans, once they had mastered the art of controlling it since, unlike a hot spring, it is a transportable resource.
63. All of the following statements can support the cooking theory EXCEPT__________.
A. cooking enabled early humans to invest less in digestive system
B. cooking enabled early humans to devote more energy to building big brains
C. our brain became larger around the same time our digestive system weakened
D. the controlled fire wasn’t mastered until about 790,000 years ago
64. The presence of biological molecules was important because_________.
A. they suggested a possible means of cooking without fire
B. they cast light on how early Homo erectus lived
C. they provided a convenient way of studying stone tools
D. they made studies of pre-historic cultures possible
_________.
65. The underlined word “plausible” probably means
A. noticeable
B. applicable
C. reasonable
D. affordable
66. What may be the conclusion of the study by Dr. Summons and his colleague?
A. Early humans were capable of making complex stone tools.
B. Hot springs help explain how human brains got so big.
C. Homo erectus were adaptable to tough and complex territories.
D. Human brains are highly advanced as shown by their size.
Section C
Directions: Read the passage carefully. Fill in each blank with a proper sentence given in the box.
Each sentence can be used only once. Note that there are two more sentences than you need.
A. Those with a slower pace also scored less well in physical exercises such as hand-grip strength and biological markers of good health.
B. There are already signs in early life of who would become the slowest walkers.
C. In fact, based on a new series of experiments, they now believe the slower a person’s tendency to walk，the less able their brain.
D. Brain scanning during their final assessment at 45 showed the slower walkers tended to have lower total brain volume and less brain surface area.
E. Until now, however, no one knew it could signify underlying brain health so much
earlier in life.
F. Researchers performed walking speed analysis on hundreds of middle-aged
people, comparing their psychological results.
Slower Walkers Have Slower Minds, Scientists Reveal
Of all human activities, few are so readily credited with enhancing the power of the mind
as going for a good walk. However, those who assume that strolling along at a gentle pace is the symbol of superior intellect should think again, scientists have said. ______67_______ Doctors have long used walking speed to gain a quick and reliable understanding of older peopled mental capability, as it is increasingly recognized that pace is associated with not only muscular strength but also the central nervous system. ______68______ The relationship was so obvious, however, that the US scientists now say walking tests could be used to provide an early indication of dementia（痴呆）.
Published in the Journal of the American Medical Association, the study revealed an
average difference of 16 IQ points between the slowest and the fastest walkers at the age of 45,
achieved when asked
This reflected both the participants’ natural walking speed and the pace they
lo walk as fast as they could. _____69______ Actually, slower walkers were shown to have
“sp eeded aging'' on a 19-measure scale devised by researchers, and their lungs, teeth and immune
systems tended to be in worse shape than the people who walked faster.
The 904 New Zealand men and women who were tested at 45 were tracked from the age of
three, each undergoing multiple tests over the years. The long-term data collection enabled researchers to establish that kids with lower IQ scores, lower linguistic ability and weaker emotional control tended to have slower walking speeds by middle age. _____70______
The research team said genetic factors may explain the link between walking speed, brain
capacity and physical health or that better brain health might promote physical activity, leading to
better walking speed. Some of the differences in health and intellect may be the result of lifestyle
choices individuals have made.
IV. Summary Writing
Directions: Read the following passage. Summarize the main idea and the main point(s) of the passage in no more than 60 words. Use your own words as far as possible.
The Psychology of Spending
Dr. Thomas Gilovich, psychology professor at Cornell University, has studied the psychology of spending for over 20 years. According to Dr. Gilovich，“We buy things to make us happy, and we succeed, but only for a while. New things are exciting to us at first, but then we
，once the freshness of our newest purchase wears off, we begin
adapt to them.” In other words
looking for something else to buy to make us happy.
Dr. Gilovich found that our satisfaction with possessions fades over time. Yet our happiness over things we've experienced increases. For that reason, he has concluded that we are
spending our money on the wrong things. A study out of San Francisco State University agrees.
The research showed that those people who spent money on experiences instead of possessions
were happier. They also thought their money was better invested.
To begin with, activities like a trip, adventure, hobby, etc. tend to bring the participants
together and unite them over a shared interest. According to Gilovich, “
We consume experiences
directly with other people.” As a result, these experiences typically create a positive link and good feelings toward the other person or people.
Besides, your experience shows others who you are and what you are. For example, you
might be someone who loves taking cooking classes. More than likely, you'll become known by
friends and family as a great cook. They won't know you as someone who owns the latest kitchen equipment.
Lastly, planned experiences arc frequently something we look forward to. Then when
the moment arrives, if we enjoy the time involved in the activity, we're left with fond memories.
These memories will often last a lifetime. Even our worst trips, on many occasions, arc later remembered with laughter.

考试六大应试技巧 一、自我暗示、消除焦虑 ①自我暗示法。用平时自己考试中曾有优异成绩来不断暗示自己：我是考生中的佼佼者；我一定能考得理想的成绩；我虽然有困难的题目，但别人不会做的题目也很多。 ②决战决胜法。视考场为考试的大敌，用过去因怯场而失败的教训鞭策自己决战决胜。 二、整体浏览，了解卷情 拿到试卷后，在规定的地方写好姓名和准考证号后，先对试卷进行整体感知，看看这份试卷共多少页、总题量是多少、分哪几大部分、有哪几种题型。这样不仅可以要防止试卷错误，尽早调换，避免不必要的损失；而且通过对全卷作的整体把握，能尽早定下作战方案。 重要的是初步了解下试卷的难易度，以便自己合理安排答题时间，避免会做的没有做，不会做的却浪费了时间的情况出现。 三、“两先两后”，合理安排 ①先易后难 ②先熟后生 四、“一慢一快”，慢中求快 一、书写速度应快，不慢慢吞吞。二、书写的内容要简明扼要，不拖泥带水，噜嗦重复，尽量写出得分点就行了。 五、分段得分，每分必争 对于会做的题目。对会做的题目要解决对而不全的老大难问题，如果出现跳步往往就会造成丢分的情况，因此，答题过程一定规范，重要步骤不可遗漏，这就是分段得分。 对于不会做的题目，这里又分两种情况，一种是一大题分几小题的，一种是一大题只有一问的。对于前者，我们的策略是“跳步解答”，第一小题答不出来，就把第一小题作为已 知条件，用来解答第二小题，只要答得对，第二小题照样得分。对于后者，我们的策略是“缺步解题”，能演算到什么程度就什么程度，不强求结论。这样可以最大程度地得到分数。 六、重视检查环节 如果自己的考试时间还有些充裕，那么根不可匆忙交卷，而应作耐心的复查。将模棱两可的及未做的题目最后要进行检查、作答，特别是填空题、选择题不要留空白。
