Kids are far better than adults at learning how to speak multiple languages. Research now shows that very young infants might have some of the best language skills of all．
A new study suggests that babies between 4 and 6 months old can tell the difference between two languages just by looking at the speaker's face．They don't need to hear word．Sometimes between 6-8 months of age, babies raised in homes where just one language is spoken lose this ability．Babies from bilingual(双语的) homes, on the other hand, keep the face-reading ability until they're at least 8 months old．
Researchers in Canada studied 36 babies from English-speaking families．Twelve of the babies were 4 months old,12 were 6 months old, and the rest were 8 months old．Each baby sat on his or her mother's lap and watched video clips(电影片断) of a woman talking．The woman was fluent in both English and French．In some clips, she read from a storybook in English．In other clips, she read in French．In all of the videos there was no sound．
1.What is mainly discussed in the passage ?
A．Language teaching．
B．Language learning
C．Babies and language learning
D．Parents and language teaching
2.What do the underlined word in the second paragraph refer to ?
A．Two or more． B．Foreign. C．difficult. D．At least one.
3.We can know from the passage that________.
A．all the babies in the study are of the same age．
B．the babies could hear the woman's voice while watching the videos．
C．the stories the woman read were written in either French or German．
D．it's still unknown how babies could tell the difference between languages．
4.Why did the 8-month-old pay no attention when the language was changed ?
A．They had lost the ability to distinguish different languages．
B．They were too tired to open their eyes and fell asleep．
C．They couldn't hear what the speaker was talking about．
D．They had lost the interest in bilingual speakers．

[1]If you can’t find your keys , ask a woman．It’s reported that females are better than males at multitasking, particularly if those tasks include searching for lost items, for example , the car keys．
[2]Researchers carried out two experiments, in which men and women have to juggle（同时做）several tasks．Examples of this include working in a busy office or cooking several dishes at once for a meal．In the first battle of the sexes , the volunteers played a computer game that required rapid changes of attention．Both sexes slowed down , but the women slowed less．This suggests that they found multitasking easier．
[3]In the second experiment , volunteers were given 8 minutes to complete a set of sums , search for restaurants on a map and work out the route they would take to search for a set of keys lost in a field．The two sexes did well on all the tasks, but the key hunt — in which the searches planned by the women were judged to be clearly superior．When it is the only thing to be done, both sexes are equally good at it．It showed that men’s ability to plan a search for lost keys breaks down, when put under the pressure of multitasking．The results suggest that women are better at multitasking than men．
[4] Women’s advantage at doing tasks has its roots in evolution．In the Stone Age , men could probably go out and hunt for food , while the women stayed at home and multi-tasked．They were always looking out for their children , as well as doing other things , like gathering fruits and doing mending and making stone tools．Men probably have somewhat more of a one-track mind．

Jealous of the kids at school who are smarter than you and seem to learn more quickly? Don’t worry． 71
72 However, according to a recent study, IQ can rise—not just by one or two points, but by as many as 21 points!
Scientists have found that IQ changes are linked to changes in part of the brain called gray matter, which was seen to grow and become denser （更加密集） in the brains of people whose IQs improved greatly．
73 One is to train your short-term memory． Previous research has proven that short-term memory is the basis for intelligence, so trying to recognize or retell something that you have seen or heard can help raise your overall brain power． 74
A good night’s sleep will also help improve your concentration． 75 It helps you stay focused for longer the next day．
Scientists have also found that exercise helps． Walking 30 minutes a day five times a week and doing exercise will help you become more knowledgeable—as well as healthier and fitter．
A． There are several ways of increasing your brain’s gray matter．
B． Your brain deals more efficiently with things you truly like．
C． With a bit of brain training, the chances are that you can be as smart as they are．
D． So maybe it’s a good idea to get your brain in training right away．
E． Getting enough sleep is like pushing the reset button in your brain．
F． The more you work on it, the better you will become．
G． People used to assume that a person’s IQ was unchangeable．

The age at which kids first fall victim to bullying (欺侮）could influence how strongly they are affected，suggests a new study. And，surprisingly，it is not the youngest kids who are hurt the most in the long term.
Bullying can have long-lasting effects，but particularly when it begins in adolescence，the researchers say. People subjected to either verbal ( 口头 上的）or physical bullying are known to be at greater risk of developing depression，anxiety disorders or to behave violently. But not everyone reacts in this way.
Children bullied for the first time before they hit adolescence seem to get over it， but those who are bullied for the first time later on in adolescence seem to become more aggressive or are more likely to turn to drink as a means of coping. These are the conclusions of psychologist Matthew Newman and colleagues from the University of Texas at Austin，US.
The team gave questionnaires to nearly 1，500 college students regarding their experience of physical and psychological bullying before adolescence—before high school—and in late adolescence—at high school. They assessed mood and mental state，judging by signs of anxiety or depression，such as sleeplessness. The group was also questioned about how they would react to certain challenges，such as humiliation.
People who were bullied all revealed slightly higher levels of stress. But while those bullied earlier in life seemed to respond normally to provocation (杉匕畔)，people bullied for the
first time late in adolescence are more withdrawn and sensitive to violence.
There are also sex differences between those bullied for the first time during adolescence， with females more likely to react aggressively when provoked and males are much more likely to turn to alcohol to escape bad situations.
The best solution in all cases was strong social support，whether from friends，family or school. Those with no one to share their problems with suffered the most.
So perhaps it is best not to shelter children completely from bullying early on，suggests Newman. “They may get stressed，but unhealthy coping really jumps out when they are bullied for the first time later on. ”
