For example, someone might say, “I just a hundred dollars on the lottery. It was great. I took that dollar ticket back to the store and it in for one hundred dollars!”
This guy is a winner, ? Maybe, maybe not. We then discover that he bought two hundred , and only one was a winner. He’s really a big !
He didn’t say anything that was , but he deliberately left out some important . That’s called a half-truth. Half-truths are not technically , but they are just as not .
Untrustworthy candidates in campaigns often use this tactic(手段). Let’s say that during Governor Smith’s last term, the state lost one million jobs and three million jobs. Then she another term. One of her opponents runs an ad , “During Governor Smith’s term, the state lost one million jobs!”That’s true. , an honest statement would have been, “During Governor Smith’s term, the state had a net gain of million jobs. ”
Advertisers will sometimes use half-truths. It’s the law to make false claims so they try to mislead you with the . An ad might boast, “Nine out of ten doctors recommend Yucky Pills to cure nose pimples. ”It to mention that they only asked ten doctors and nine of them work for the Yucky Corporation.
This kind of deception happens too often. It’s a sad fact of life: Lies are lies, and sometimes the truth can lie as well.

Traditionally, scientists have thought that humans’ superior intelligence derived(源于)mostly from the fact that our brains are three times bigger than those of our nearest living relatives, chimpanzees. People even used to believe that because men have slightly larger brains than women that men are smarter.
This, however, is not the truth. Scientists at University College London in the UK have found that brain organization, and not brain size, is the key to the superiority of human intelligence, reported Live Science.
Through millions of years of evolution, our ancestors were constantly pushed to get smarter so that they could meet the demands of new environments. However, holding this growing intelligence in increasingly large brains was not the best choice because bigger brains require more energy to power. “This is when reorganization may come into play, ”said Christophe Soligo, a member of the London research team.
In the study, scientists looked at the brains of 17 species of primates(灵长目动物), including monkeys, apes and humans. They found that in the process of evolution, brains didn’t keep growing as a whole. Certain regions of the brain grew prior to others in response to species’ needs, and in this way they could make the best use of their limited brain space.
For example, when early humans were struggling to survive, the brain region in charge of using tools and finding food grew in size more than other regions. But in modern times, the prefrontal cortex(前额皮质)—the region in charge of social cognition(认知), moral judgments and goal-directed planning—grew more than the rest of the brain.
Think of the brain as a room. If a big room is poorly organized, it doesn’t necessarily store more stuff than a smaller one.
Paul Manger, professor at the University of the Witwatersrand, South Africa, explains this principle using the example of whales. He told Scientific American: “Whales have big brains, absolutely. But if you look at the actual structure of the brain, it’s not very complex. Brain size only matters if the rest of the brain is organized properly. ”
小题1:It has recently been found that humans are smarter than the other animals mainly because .
| A．they are a species of primates |
| B．they have much larger brains |
| C．their brain structure is more complex |
| D．they were constantly pushed to get smarter |
| A．the brain kept growing in size to adapt to new environments |
| B．most regions of the brain didn’t change |
| C．the prefrontal cortex grew more than the rest of the brain |
| D．humans’ brains became increasingly simple so that humans could survive |
| A．Gender makes a difference in intelligence. |
| B．The size of the brain has nothing to do with intelligence. |
| C．Species whose brain is organized properly tend to be smarter. |
| D．Larger brains are usually organized better than smaller ones. |
| A．by presenting research data |
| B．by giving examples |
| C．by making a comparison |
| D．by analyzing cause and effect |
LONDON—Scientists have found an unusual way to prevent our planet from overheating: move it to a cooler spot. All you have to do is send a few comets(彗星)in the direction of Earth, and its orbit will be changed. Our world will then be sent spinning into a safer, colder part of the solar system.
This idea for improving our climate comes from a group of US National Aeronautics and Space Administration(NASA)engineers and American astronomers. They say their plan could add another six billion years to the useful lifetime of our planet—effectively doubling its working life.
The plan put forward by Dr. Laughlin, and his colleagues Don Korycansky and Fred Adams, needs carefully directing a comet or asteroid so that it passes close by our planet and sends some of its gravitational energy to Earth.
“Earth’s orbital speed would increase as a result and we would move to a higher orbit away from the Sun, ”Laughlin said.
Engineers would then direct their comet so that it passed close to Jupiter or Saturn. The comet would pick up energy from one of these giant planets. Later its orbit would bring it back to Earth, and the process would be repeated.
In the short term, the plan provides an ideal way to global warming, although the team was actually concerned with a much greater danger. The Sun is certain to heat up in about a billion years and so“seriously compromise” our biosphere(生物圈)—by cooking us.
That’s why the group decided to try to save Earth.
The plan has one or two worrying aspects, however. For a start, space engineers would have to be very careful about how they directed their asteroid or comet towards Earth. The smallest miscalculation(误算)in orbit could fire it straight at Earth—with deadly consequences.
There is also the question of the Moon. As the current issue of Scientific American magazine points out, if Earth was pushed out of its current position, it is“most likely the Moon would be stripped away from Earth”. This would greatly change our planet’s climate.
小题1:What makes the scientists plan to move Earth?
| A．A few comets are moving to the direction of Earth. |
| B．Earth’s working life is coming to an end soon. |
| C．Earth will become too hot for mankind to keep alive. |
| D．The moon is moving farther and farther away from Earth. |
| A．12 billion | B．6 billion |
| C．18 billion | D．24 billion |
| A．The comet might hit Earth and man might lose the Moon. |
| B．Earth might be moved too far away and man might be frozen to death. |
| C．The comet might hit Jupiter or Saturn and never return to Earth. |
| D．Earth’s working life might be greatly shortened. |
| A．Provide. | B．Benefit. |
| C．Share. | D．Endanger. |
The research comes as educators in some countries are reducing time for activities like physical education．They are using the time instead for academic subjects like maths and reading．The studies appeared between 2007 and 2013．They included more than 55，000 children，aged 6 to 18．
Amika Singh：“Based on the results of our study，we can conclude that being physically active is beneficial for academic performance. There are，first，Physiological explanations，like more blood flow, and so more oxygen to the brain．Being physically active means there are more hormones(荷尔蒙)produced like endorphins(内啡肽)．And endorphins make your stress level lower and your mood improved, which means you also perform better.”
Also，students involved in organized sports learn rules and how to follow them．This could improve their classroom behavior and help them keep their mind on their work．
The study leaves some questions unanswered，however．Ms．Stash says it is not possible to say whether the amount or kind of activity affected the level of academic improvement．This is because of differences among the studies .
Also．they were mostly observational studies．An observational study is where researchers do not do controlled comparisons．They only describe what they observe．So they might observe a link that students who are more active often have better grades．But that does not necessarily mean being active was the cause of those higher grades．
The researchers said they found only two high - quality studies．They called for more high-
quality studies to confirm their findings．They also pointed out that “outcomes for other parts of the world may be quite different. ”
Still，the general finding was that physically active kids are more likely to do better in school．Ms．Singh says schools should consider that finding before they cut physical education programs．Her paper on “Physical Activity and Performance at School”is published in the Archives of Pediatric and Adolescent Medicine．
小题1:The passage mainly tells us that ＿＿＿＿
| A．a research on physical education has been done by the researchers |
| B．there exists a possibility that physical activity leads to higher grades |
| C．the amount or kind of activity directly affects academic level |
| D．the research shows that the children aged 6 to 1 8 don"t do sports |
| A．Being mentally active is good for academic subjects． |
| B．The more hormones you have，the more stressed you will get． |
| C．They have found many high-quality studies to prove the research． |
| D．The educators in the research think studies，not exercise，mean much to students． |
| A．good marks result from high-quality study |
| B．findings probably vary in different areas |
| C．physical activity will spread all over the world |
| D．academic performance depends on the surroundings |
| A．To call our attention to the sports at school． |
| B．To introduce all types of physical activities． |
| C．To represent the academic performance． |
| D．To improve students" health ． |
Climate change is widely known to produce warming conditions in the oceans, but extreme cold-water events have become more frequent and serious as well. In 2010, for example, coral reefs around the world faced on of the coldest winters and one of the hottest summers on record.
During a unique experiment, corals under cold temperatures suffered greater damage in just days compared with heat treated corals. Yet the researchers found that corals were eventually able to adjust to the cold conditions, make their health stable and continue to grow. However, over the long term corals subjected to heat suffered more greatly than those in cold, with evidence of severe whitening and growth stoppage, which leads to death.
The coral’s ability to adjust to cool temperatures surprised the researchers, who say the study’s results show the complexities(复杂性) of monitoring coral health in response to different environmental factors(因素).
“Global warming is associated with increases but also decreases of temperatures,” said Deheyn, one of the researchers. “Not much has been known about the comparative effects of temperature decrease on corals. These results are important because they show that corals react differently to temperature differences, which is important for future management of coral reefs in the field of climate change.”
小题1:Which of the following is TRUE according to the passage?
| A．Corals are unable to adjust to temperature changes. |
| B．Cold temperature causes greater damage to corals. |
| C．Hot temperature helps coral reefs to grow quickly. |
| D．Heat and cold damage corals in their own ways. |
| A．scientists used to pay no attention to the effect of cold events on corals |
| B．2010 witnessed one of the greatest temperature differences on record |
| C．corals prefer warmer conditions to cold temperatures in the long run |
| D．global warming has nothing to do with the decrease of temperature |
| A．corals may continue to grow in cold events after a few days |
| B．cold events help corals grow more quickly in a short time |
| C．corals show no response to hot temperatures in the first days |
| D．corals are whitened mainly because of warm temperatures |
| A．news report | B．scientific study | C．great imagination | D．natural conditions |
The Caltech scientists say carbonate（碳酸盐）minerals formed on Mars at about eighteen degrees Celsius. They reached the finding after studying a meteorite（陨石）that had its beginnings near the Martian surface.
Today, the average temperature on Mars is sixty-three degrees below zero Celsius.
The finding was reported on the website of the National Academy of Sciences. Caltech Assistant Professor Woody Fischer helped to prepare the report. He says eighteen degrees Celsius is not especially cold or hot. He says this makes the finding extremely interesting. Knowing the temperature can give scientists an idea of the climate on Mars long ago. It can also help them decide whether the planet had liquid water. Spacecraft orbiting Mars have shown what appear to be rivers, lakebeds and mineral deposits. These pictures suggest that, at one time, water did flow there. Mars Rover vehicles and other spacecraft have proved the information.
The meteorite the scientists examined is one of the oldest known rocks in the world. It is called the Allan Hills meteorite. Its name came from the place in Antarctica where it was found in 1984. The meteorite is believed to have blown loose from the Mars" surface when another space rock struck its "home."
小题1:The underlined word “establish” in Paragraph 1 probably means “___________”.
| A．to set up |
| B．to make people accept a belief |
| C．to discover or prove |
| D．to start having a relationship with others |
| A．By studying Allan Hills meteorite. |
| B．By using spacecraft orbiting Mars. |
| C．By studying minerals gathered on Mars. |
| D．By studying a meteorite on the Martian surface. |
| A．Measuring the temperature of Mars. |
| B．Taking photos of the surface of Mars. |
| C．Finding that there is water flowing on Mars. |
| D．Proving where human beings will probably land on Mars. |
| A．In a biography of scientists. | B．In a geography magazine. |
| C．In an environment report. | D．In a science report. |
