The scene in the Hollywood movie The Day After Tomorrow, where global warming could soon turn the global climate (气候) into a new ice age, may never occur, according to new research.
The next ice age could be 15,000 years away, say European scientists who last month announced a continuous record of 7.40,000 years of climate data (数据) obtained from the Antarctic ice.
Scientists from 10 nations have now almost completely drilled through a 3,000-meter.depth of ice high in the Antarctic mainland. They figure out that the area where summer temperatures can fall to –40℃, has at least 900,000 years of snowfalls,, kept as neatly as the growth rings of a tree. And the ice and air caught in each layer(层) have begun to answer questions about the climates in the past..
The results show that there have been eight ice ages in the past 740, 000 years and eight warmer periods. And by comparing the pattern of global conditions today with those of the past, the researchers reported in Nature that the present warm period could last another 15, 000 years.
Research suggests that there is a very close connection between greenhouse gas levels and global average temperatures. It also shows that carbon dioxide (二氧化碳) levels are the highest for at least 440,000 years.
"If people say to you: the greenhouse effect is a good thing because we would go into an ice age otherwise, our data say no, a new ice age is not hanging over our heads,” said Eric Wolff from the British Antarctic Survey. "Now we have eight examples of how the climate goes in and out of ice ages… and you can learn what the rules are that go into the climate models that tell us about the future."
Scientists found that whenever temperatures rose in the frozen record, so did carbon dioxide level. "In 440,000 years we have never seen greenhouse gas get as thick as it is today," said Dr Wolff.
48. In drilling through the ice in Antarctica, scientists, have found that______.
A. the lowest temperature there is -40℃ B. the depth of ice is 3,000 meters
C. the ice has existed for 15,000 years D. snowfalls are kept in certain patterns
49. The information of the global climate conditions in the past can be obtained through______.
A. separating carbon dioxide from the air
B. examining the growth rings of trees
C. comparing temperatures in different areas
D. studying the ice and air caught in each layer
50. We can infer from Eric Wolff's words that_______.
A. there is something wrong with the data B. greenhouse effect is always a bad thing
C. a new ice age will not come in the near future
D. greenhouse gas will get thick in the future
51. What would be the best title for the passage?
A. Research over the Antarctic area. B. Warm period to last about 15, 000 years.
C. Report on the eight ice ages in the past. D. Hollywood movies and the global climate.
48---51 DDCB
解析:
48.解析:这是一道细节推断题。第三段“They figure out that the area where summer temperatures can fall to -40℃, has at least 900 000 years of snowfalls, kept as nearly as the growth rings of a tree.”说明科学家们发现,积雪保持着一定的模式。
49.解析:这是一道细节推断题。根据第三段“And the ice and air caught in each layer have begun to answer questions about the climates in the past.”可判断出根据沉积在各层的雪和空气的研究可知道过去气候的状况。
50.解析:这是一道细节推断题。根据倒数第二段Eric Wolff说的话可判断出他认为在最近的将来不会出现冰川时代。
51.解析:这是一道主旨题。第二段“The next ice age could be 15 000 years away”是科学家最新研究的成果,说明地球将会在15 000年内处于暖和的时期。
Some years ago, a Miami woman walking through an office building noticed two men standing together.Several minutes after her leaving, the men murdered a person working in the building.The police determined that the woman was the only witness and could possibly describe them.However, her memory of the men proved disappointingly unclear.Several days later, psychologist Ronald Fisher was brought in to obtain a more complete account from the woman.His interview produced a breakthrough—the woman reported a clear picture of one of the suspects.The important information enabled the police to arrest the suspect and close the case.
The police asked Fisher for help because of his rich knowledge in cognitive(认知) interview, a kind of memory - rebuilding process.Memory researchers have found that people trying to remember a past event often only recall part of the relevant information.Human memory is selective and it is often distorted by stress.But a person's accurate recall of an event or understanding of a question can be improved using specific interviewing techniques.The "cognitive interview" was developed in the late 1990s.It encourages the witness to take an active role in recalling information rather than giving answers only to someone else's questions.The witness first describes what happened in his or her own words, with no interviewer interruptions.The interviewer then goes further with specific techniques, such as having the witness tell the details of what happened from different perspectives (角度) .
The cognitive interview focuses on guiding witnesses through four general recalling techniques: thinking about physical surroundings and personal feelings that existed at the time of past events; reporting everything that connects to mind about those events, no matter how broken it is retelling events in a variety of time orders, such as from beginning to end, end to beginning, forward or backward; and adopting different perspectives while recalling events.
Experiments with police detectives trained in this demanding interview method find that they obtain nearly 50% more information from witnesses than before training, while error rates remain about the same.It is proved that cognitive interviews are quite important tools in improving the accuracy and completeness of witness testimony (证词).
【小题1】The purpose of the passage is to _____.
A.give an account of a murder case. |
B.introduce an idea of cognitive interview. |
C.prove Fisher was an expert in cognitive interview. |
D.help a witness to recall information in a cognitive interview. |
A.The exact time at which a murder took place. |
B.The information about the event in the time order. |
C.The important things that come to his or her mind. |
D.The surroundings and feelings at the time of the event. |
A.the witness is encouraged to take part in recalling information. |
B.the interviewer should interrupt the witness from time to time. |
C.the interview should take place outside the police station. |
D.the witness should recall details at the scene of the event. |
A.arranged | B.balanced | C.changed | D.examined |
A three-year independent investigation into the September 11, 2001 attack on the Pentagon has yielded new eyewitness evidence which, according to the Southern California-based researchers who conducted the investigation conclusively (and unfortunately), establishes as a historical fact that the violence which took place in Arlington that day was not the result of a surprise attack by suicide hijackers, but rather a military black operation involving a carefully planned and skillfully executed deception."
A CNN Reporter at the scene states that there is no evidence that a 757 hit the Pentagon.
What hit the Pentagon? A Boeing 757 loaded with passengers and fuel right? Who was on Flight 757? According to the Flight Information there were No Arabs on it. That makes me wonder if Flight 757 actually existed at all.
From the pictures and the videos, people can find that there are several doubtful points that need to be taken into consideration, for example the marker line on the grass in the satellite and ground pictures, the different colors of the smoke, the hole which the plane impacted, and the standing pylons (架线塔).
Also, from the comparison of the different pictures, people can find some other strange points. For example, the gear (齿轮) is not the matching one. The wreckage of the plane is not the one from the American Airlines. The glass on the pavement of the pole is another doubtful point. The last thing that need considering is about the collapse. One of the gif video shows the plane impacting the Pentagon. The only problem with this video footage is that it has been altered (改变) and can not be fully trusted.
These crash photos and videos shown here clearly have been doctored (篡改) and don't even match the physics of what happened. So where is the real video? It leaves me many questions. Is this a missile? It is a real enigma.
