8．第二节
You'd think the human race would have understood sleeping very well by now，but many of us are still sleeping poorly．Part of the problem is that we have wrong information and beliefs about this important health need．Let's set the facts straight．（36）B
1．More sleep is better for you．
There could be such a thing as too much sleep．The amount of sleep we need varies by person and also changes as we age．Harvard researchers found that a lot of sleep（9 hours or more） is linked with poor sleep quality．（37）DAim for better sleep
2．（38）A
Alcohol can help most people fall asleep．However，it also can cause you to wake up more during the night，decreasing your keep sleep quality．Consider drinking non-alcoholic drink before bed instead．
3．If you wake up in the middle of night，lie in bed until you eventually fall back asleep．（39）EWe all hope to quickly fall back asleep．So we tend to stay in bed hoping it'll happen tat any minute now．If that doesn't happen，though，within 15minutes，most exporters recommend getting out of bed to do something that occupies our bodies and brains without over stimulating（刺激）us．Try not to check the clock either．
You can catch up on sleep on weekends．
When we lose sleeping during the week，we accumulate a kind of sleep"debt"．（40）GNot so fact．This might actually make you sleepier the next week．Instead of waking up later on the weekends，you'd better go to sleep earlier or perhaps take a nap in the afternoon．

A．Alcohol helps you sleep．
B．Here are some things you might been told about sleeping but aren't completely true．
C．Everyone should get 7-8hours of sleep per night．
D．So don't aim for more sleep-even on the weekends．
E．Waking up in the middle of the night is the annoyance，but it happens to all of us．
F．You'll have a better day and perhaps sleep better at night．
G．Can you pay that debt back by sleeping on Saturday or Sunday？

4．Blind imitation （模仿）is self-destruction．To those who do not recognize their unique worth，imitation appears attractive；to those who know their strength，imitation is unacceptable．
    In the early stages of skill or character development，imitation is helpful．When I first learned to cook，I used recipes（菜谱）and turned out some tasty dishes．But soon I grew bored．Why follow someone else's way of cooking when I could create my own？Imitating role models is like using training wheels on a child's bicycle；they help you get going，but once you find your own balance，you fly faster and farther without relying on them．
    In daily life，imitation can hurt us if we subconsciously（下意识地）hold poor role models．If，as a child，you observed people whose lives were bad，you may have accepted their fear and pain as normal and gone on to follow what they did．If you do not make strong choices for yourself，you will get the results of the weak choices of others．
    In the field of entertainment，our culture glorifies celebrities．Those stars look great on screen．But when they step off screen，their personal lives may be disastrous．If you are going to follow someone，focus on their talent，not their bad character or unacceptable behaviors．
    Blessed is the person willing to act on their sudden desire to create something unique．Think of the movies，books，teachers，and friends that have affected you most deeply．They touched you because their creations were motivated by inspiration，not desperation．The world is changed not by those who do what has been done before them，but by those who do what has been done inside them．Creative people have an endless resource of ideas．The problem a creator faces is not running out of material；it is what to do with the material knocking at the door of imagination．
    Study your role models，accept the gifts they have given，and leave behind what does not server you．Then you can say，^"I stand on the shoulders of my ancestors'tragedies and declare victory，and know that they are cheering on．"

51．Imitation proves useful when youC．
A．know you are unique
B．lose the balance of life
C．begin to learn something new
D．get tired of routine practice
52．To avoid the bad result of imitation，we shouldC．
A．forget daily fear and pain
B．ask others tor decisions
C．choose the right example
D．stay away from stars
49．According to the author，the world moves on because of those who areB．
A．desperate to influence others with their knowledge
B．ready to turn their original ideas into reality
C．eager to discover what their ancestors did
D．willing to accept others'ideas
50．The trouble a creator faces isD．
A．the lack of strong motivation
B．the absence of practical ideas
C．how to search for more materials
D．how to use imagination creatively
51．What is the author's purpose in writing this passage？A
A．To highlight the importance of creatively．
B．To criticize the characters of role models．
C．To compare imitation with creation．
D．To explain the meaning of success．

19．Persuasion is the art of convincing someone to agree with you．According to the ancient Greeks，there are three basic tools of persuasion：ethos，pathos，and logos．
Ethos is a speakers way of convincing the audience that she is trustworthy，honest and reliable．One common way a speaker can develop ethos is by explaining how much experience or education she has in the field．After all，you're more likely to listen to advice about how to take care of your teeth from a dentist than a fireman．A speaker can also create ethos by convincing the audience that she is a good person．If an audience cannot trust you，you will not be able to persuade them．
Pathos is a speaker's way of connecting with an audience's emotions．For example，a politician who is trying to convince an audience to vote for him might say that he alone can save the country from a terrible war．These words are intended to fill the audience with fear，thus making them support him．Similarly，an animal charity might show an audience pictures of injured dogs and cats，to make the viewers feel pity．If the audience feels bad for the animals，they will be more likely to donate money．
Logos is the use of facts，statistics，or other evidence to support your argument．An audience will be more likely to believe you if you have convincing data to back up your claims．Presenting this evidence is much more persuasive than simply saying"believe me"．
Although ethos，pathos，and logos all have their strengths，they are often most effective when used together．Indeed，most speakers use a combination of ethos，pathos，and logos to persuade their audiences．So，the next time you listen to a speech，watch a commercial，or listen to a friend try to convince you to lend him some money，be on the lookout for these ancient Greek tools of persuasion．

32．Why does the author say persuasion is an art？B
A．They both entertain the audience．
B．They both require great skill to achieve．
C．They both demand full attention from the audience．
D．They were both common topics of ancient Greek writers．
33．How is a speaker able to show her ethos to the audience？D
A．By expressing her sympathy with the audience．
B．By telling the audience about her personal preference．
C．By using beautiful language to make her statements attractive．
D．By showing her knowledge and experience relating to the topic．
34．What can we learn about the three aspects of persuasion？B
A．Ethos is the most important aspect of persuasion．
B．Each aspect has a different effect on the audience．
C．Honesty is the key to making your arguments believable．
D．Political leaders mostly use pathos to persuade their audience．
35．An advertisement for washing powder which claims that M scientific tests show that our powder kills 95% of all bacteria"is mainly usingC．
A．ethos B．pathos C．logos D．a combination of all three．

20．The baby is just one day old and has not yet left hospital．She is quiet but alert （警觉）．Twenty centimeters from her face researchers have placed a white card with two black spots on it．She stares at it carefully．A researcher removes the card and replaces it by another，this time with the spots differently spaced．As the cards change from one to the other，her gaze （凝视） starts to lose its focus-until a third，with three black spots，is presented．Her gaze returns：she looks at it for twice as long as she did at the previous card．Can she tell that the number two is different from three，just 24 hours after coming into the world？
Or do newborns simply prefer more to fewer？The same experiment，but with three spots shown before two，shows the same return of interest when the number of spots changes．Perhaps it is just the newness？When slightly older babies were shown cards with pictures of objects （a comb，a key，an orange and so on），changing the number of objects had an effect separate from changing the objects themselves．Could it be the pattern that two things make，as opposed to three？No again．Babies paid more attention to squares moving randomly on a screen when their number changed from two to three，or three to two．The effect even crosses between senses．Babies who were repeatedly shown two spots became more excited when they then heard three drumbeats  than when they heard just two； likewise （同样地） when the researchers started with drumbeats and moved to spots．

17．Cutting trees in half can help scientists understand the past and now it appears it can be used to predict the future．Researchers have been looking at ring growth from trees to make sense of past weather patterns such as droughts and rain．
Combining data from the rings allowed them to create a copy of pictures of climate changes over the past 2，000 years and this information could also be used to foresee future famine（饥荒），unrest and conflict．The project has been named Old World Drought Atlas，or OWDA．
Its main author，Columbia biologist Edward Cook，has already carried out similar projects using trees to create chronological（按顺序排列的）maps of drought  in Asia and North-America．He believes that combining the three atlases could throw light on the global causes of drought and climate change．
The study，for instance，gave special attention to the importance of one of such causes，the North Atlantic Oscillation（涛动），in affecting climate patterns in Europe，and specifically in making Europe wetter north of the Alps and drier south of them．
The OWDA also helped analyse historical events from a climatic perspective．For instance，the 1740-174lfamine in Ireland had so far been explained by an unusually cold winter and spring，but the atlas shows that unusually low rainfall over the spring and summer of 1741 could also have played a role．Finally this made growing food nearly impossible and caused a continent-wide famine．
A better grasp of these processes could even make it possible to predict future famine，unrest and conflict．
Cook said，64The Old World Drought Atlas fills a major geographic gap in the data that's important to determine patterns of climate changes in time．That's important for understanding causes of many droughts，and it's important for climate modelers to test hypotheses（偎说）  of climate forcing and change．

32．Why is ring growth useful in research？B
A．It's the best way to understand the past．
B．It could be used to predict the future．
C．It could be used to prevent the outbreak of droughts and rain．
D．It isn't mentioned in the passage．
33．People worldwide can read chronological maps of droughtA．
A．in Asia     B．in Africa
C．in Europe    D．in South America
34．What is the author's attitude toward the study of OWDA？C
A．Positive．B．Negative．
C．Objective．D．Conservative．
35．Why did the author of the passage mention what Cook said？B
A．To show he interviewed Cook himself．
B．To tell us the importance of OWDA．
C．To compare climate variability．
D．To analyse how to predict droughts．
