　　A new study has found that it may be possible to train people to be more intelligent，increasing the brainpower they had at birth.

　　Until now，it has been widely assumed that the kind of mental ability that allows us to solve new problems without having any relevant previous experience—what psychologists call fluid intelligence—is innate and cannot be taught（though people can raise their grades on tests of it by practicing）.

　　But in the new study，researchers describe a method for improving this skill，along with experiments to prove it works.

　　The key, researchers found, was carefully structured training in working memory—the kind that allows memorization of a telephone number just long enough to dial it. This type of memory is closely related to fluid intelligence，so the researchers reasoned that improving it might lead to improvements in fluid intelligence.

　　First they measured fluid intelligence of volunteers using standard tests. Then they trained each in a complicated memory task—the child’s card game，in which they had to recall a card they saw and heard. During the course, they needed to ignore irrelevant items，monitor ongoing performance，manage two tasks at the same time and connect related items to one another in space and time.

　　The four groups experienced a half-hour of training daily for 8，12，17 and 19 days，respectively. To make sure they were not just improving their test-taking skills，the researchers compared them with control groups that took the tests without the training.

　　The results, published Monday in The Proceedings of the National Academy of Sciences，were striking. Improvement in the trained groups was a lot greater. Moreover，the longer they trained, the higher their scores were. All performers，from the weakest to the strongest，showed significant improvement.

　　“Our results show you can increase your intelligence with proper training.”said Dr Jaeggi, a co-author of the paper.“No one knows how long the gains will last after training stops，”he added，“and the experiment’s design did not allow the researchers to determine whether more training would continue to produce further gains.”

67．The researchers thought the key to improving the intelligence was ______________.

A．memorizing telephone numbers

B．improving working memory

C．training in concentration

D．recalling a card

68．The following aspects of the training help increase intelligence EXCEPT___________.

A．ignoring irrelevant items

B．monitoring ongoing performance

C．managing two tasks at the same time

D．using previous experience

69．When the experiment was conducted，the researchers______________.

A．trained the four groups for the same period of time

B．only made comparisons between the four groups

C．compared the four groups with control groups

D．trained the four groups together

70．By writing the article，the writer intends to ______________.

A．inform the readers of a new study

B．call on people to be trained to increase intelligence

C．prove one’s born brainpower can be improved

D．tell people the improved intelligence will last forever

The movement was so fierce that several passengers felt 27 and had to use airsickness bags. As you might guess，that’s not good thing to have happen in a(n) 28 　space because it only 29 　to increase the discomfort of the situation.

About twenty minutes into the adventure，the entire airplane became very 30 .

“Most experiences of absent-mindedness ,forgetting where you left something or wondering why you just entered a room , are caused by a simple lack of attention, ” says Schacter. “You’re supposed to remember something, but you haven’t encoded（编码） it deeply.”

　Encoding, Schacter explains, is a special way of paying attention to an event that has a major impression on recalling it later. Failure to encode properly can create troublesome situations. If you　put your mobile phone in a pocket, for example, and don’t pay attention to what you did because you’re involved in a conversation, you’ll probably forget that the phone is in the jacket now hanging in your cupboard.  “Your memory itself isn’t failing you, ” says Schacter, “Rather, you didn’t give your memory system the information it needed.”  http://wx.jtyjy.com/

　Lack of interest can also lead to absent -mindedness. “A man who can recite sports statistics from 30 years ago, ” says Zelinski, “ may not remember to drop a letter in the mailbox.”Women have slightly better memories than men, possibly because they pay more attention to their environment, and memory depends on just that.

　　“Visual cues（ 视觉提示 ）can help prevent absent--mindedness, ”says Schacter, “But be sure the cue is clear and available. ”If you want to remember to take a medicine with lunch, put the pill bottle on the kitchen table—don’t leave it in the medicine box and write yourself a note that you keep in a pocket.

　　Another common experience of absent - mindedness: walking into a room and wondering why you’re there. Most likely, you were thinking about something else. “Everyone does this from time to time, ”says Zelinski. “The best thing to do is to return to where you were before entering the room, and you’ll likely remember.”

1.The writer of the passage thinks that encoding properly is very important because ________.

　　A. it enables us to recall something from our memory

　　B. it slows down the process of losing our memory

　　C. it helps us understand our memory system better

　　D. it helps us to get back to where we were

2.One possible reason why women have a little better memories than men is that________.

　　A. they rely more on the environment

　　B. they have a wider range of interests

　　C. they have an unusual power of focusing their attention

　　D. they are more interested in what’s happening around them

3.Why can a note in the pocket hardly serve as a reminder? ________.

　　A. It will easily get lost

　　B. It is out of your sight

　　C. It’s not clear enough for you to read

　　D. It might get mixed up with other things

4.From the last paragraph we can learn that________.

　　A. repetition might help improve our memory

　　B. memory depends to a certain extent on the environment

　　C. we’d better return to where we were if we forget things

　　D. we should think about something else while doing one thing

5.The passage is mainly about ________.

　　A. the memory system of persons

　　B. a way of encoding and recalling

　　C. the causes of absent-mindedness

　　D. the impression of the environment on memory

The human nose is an underestimated tool. Humans are often thought to be  1___ smellers compared with animals, but this is largely because, unlike animals, we stand upright. This means that our noses are  2  to detecting those smells which float through the air,  3  the majority of smells which stick to surfaces. In fact though, we are extremely sensitive to smells, even if we do not generally realize it. Our noses are capable of  4  human smells even when these are  5  to far below one part in one million.

　　  6     , some people find that they can smell one type of flower but not another, while others are sensitive to the smells of both flowers. This may be because some people do not have the genes necessary to generate  7     smell receptors in the nose. These receptors are the cells which sense smells and send  8    to the brain. However, it has been found that even people insensitive to a certain smell at first can suddenly become sensitive to it when  9     to it often enough.

　　The  10   for insensitivity to smell seems to be that brain finds it  11    to keep all smell receptors working all the time but can  12   new receptors if necessary. This may also explain why we are not usually sensitive to our own smells we simply do not need to be. We are not  13     of the usual smell of our own house but we  14     new smells when we visit someone else's. The brain finds it best to keep smell receptors _ 15    for unfamiliar and emergency signals such as the smell of smoke, which might indicate the danger of fire.
