Article: Those who spend more pre-bedtime hours using the Internet or watching television are more likely to report insufficient sleep, even though they sleep almost as long as people spending fewer pre-bedtime hours in front of a computer or television screen, survey findings show. "While many people use electronic media, say, the Internet, it should be noted that the longer media use before sleep can trigger (self-perceived) insufficient sleep," lead researcher Dr Nakamori Suganuma, of Osaka University, Japan, told the reporter. He and colleagues obtained data on self-perceived sleep problems and the use of electronic media prior to bedtime from 5,875 altogether Japanese respondents in two separate Internet-based surveys. Their findings are published in Sleep and Biological Rhythms. Nearly half of the respondents associated their problem with electronic media use before bedtime. Longer electronic media users were also more likely to report insufficient sleep. "Overall, 29% of light users (less than 1.5 hours) listed electronic media use as a possible cause of their insufficient sleep. By comparison, 40% of medium users (1.5 to 3 hours) and 54% of heavy users (more than 3 hours) said the same. However, longer Internet and television use before bedtime did not _ less actual sleep. While heavy users averaged about 3 more hours in front of computer or television screens than light users, the heavy users averaged only about 12 minutes less pre-workday sleep time than light users. Notably, Suganuma said, "Internet use affected self-perceived insufficient sleep more than TV watching not only in younger Internet users but also in middle-aged or aged Internet users." Up to 38% of the respondents listed accessing the Internet far into the night as a possible cause for their sleep disturbance, while about 25% said watching television far into the night caused it. The findings suggest that while heavy computer and television use before bedtime has a small effect on sleep duration, it may have a more significant effect on "sleep... Question: Heavy computer and television user before bed time are more likely to be _ than light ones. - energetic - happy - sleepy - clever

(Question)
Read the following article and select the best answer. Article: Squirrels often communicate with whistles, chirps and chucks, which sound like the word "chuck". Whistles and chirps are like the sounds that many birds make.Now scientists have translated some of their squirrel-speak. Hare, a professor of zoology at the University of Maniloha in Winnipeg, and his team managed to record squirrels' alarm calls.The researchers studied the sounds and then played them back to 60 wild squirrels, which the scientists approached individually with a video recorder to capture their reponses.Some squirrels lifted their heads up and became.Alert .Creatures that were more frightened simply ran for their lives and dived into caves. "In effect then, whistles that mix with chucks say 'there's an enemy of average threat that's here', and whistles without chucks say 'there's an enemy of seemingly average threat around here somewhere', while pure chirps say, 'I'm hiding here because there's an immediate danger.' " Hare told.Discovery News. Hare and some other researchers believe such sounds arc part of an advanced language that develops just as all other communication systems. Although squirrels risk their lives when they call out to warn others of threats, other squirrels might admire this behaviour, thus increasingly the caller's social status, like humans who look up to heroes. Hare added that other animals, such as birds, probably understand at least some squirrel language, since they also may benefit from the alarm calls. In fact, another Canadian study found that deep-voiced, black-capped chickadees have their own language too.According to certain research, there are a lot of tidings in chickadees' calls, such as directing fellows' activities, keeping in contact between mates, and raising alarms. While chickadees and other birds are often welcomed into gardens by homeowners, squirrels are frequently viewed as pests . Hare wishes a greater understanding of the complex social lives and communication systems of squirrels will provide "hope that humans will gain a greater appreciation and... Question: The text mainly talks about - the study on the language of squirrels - the comparison between squirrels and chickadees - the calling for the protection of squirrels - the ways for squirrels to escape from their enemies
(Answer)
the study on the language of squirrels

Ques:Read the following article and select the best answer. Article: Most people who move to a foreign country or culture may go through some form of culture shock,and its degree is determined by the differences between cultures,the anxiety to adapt to a new culture and the familiarity with a new culture,etc.If you go,for example,to a culture that is far different from your own,you're likely to experience culture shock more sharply than those who move to a new culture knowing the language and the custom of it. It is important to understand and learn how to deal with culture shock if you are to adapt successfully to your new home's cultures.There are four general stages of cultural adjustment,and being aware of them helps you understand that culture shock won't last long.It's just a process you are going through rather than a constant situation. The first stage is usually referred to as "the honeymoon stage".Upon arriving in a new environment,you'll be interested in the new culture.Everything will seem thrilling and everyone will seem friendly and helpful.During this stage you are merely taking in these impressions passively. But it isn't long before the honeymoon stage gives way to the second stage--"the withdrawal stage".The excitement you felt before is gone and problems arise.The language is hard to learn,people are unusual and unpredictable,friends,are hard to make,and simple things like shopping and going to the bank are challenges.It is at this stage that you are likely to feel anxious and homesick,and you will probably find yourself complaining about the new culture or country.This is the stage called "culture shock". At some point,if you can manage it well,you'll begin the transition into the next stage,"the recovery stage",in which you'll feel more confident functioning in the new culture.Customs and traditions are clearer and easier to understand.At this stage,you'll deal with new challenges with humor rather than anxiety. Question: According to the passage,culture shock can be _ . - dealt with more easily for some people - reduced by learning the language alone - avoided by knowing adjustment stages - got rid of by learning just the custom

Ans:
dealt with more easily for some people
