RTCA ,an organization which advises the aviation industry ,has suggested that all airlines ban, such devices from being used during “key” stages of flight ,particularly take-off and landing .Some experts have gone further ,calling for a total ban during all flights .Nowadays ,rules on using these devices are left up to airlines. And although some airlines ban passengers from using such equipment during take-off and landing ,most are not willing to exercise a total ban ,if many passengers want to work during flights .
The difficulty is understanding how electromagnetic fields might affect an aircraft’s computers .Experts know that portable devices give off radiation which affects those wave lengths which aircraft uses for communication .But because they have not been able to reproduce these effects in a laboratory ,they have no way of knowing whether the interference might be dangerous or not .
The fact that aircraft may be in trouble because of the interference raises the danger
that some people may use radio systems in order to damage navigation(导航)equipment .As worrying ,though ,is the passenger who can’t hear the instruction to turn off his radio because the music is too loud .

D They were caused by the passengers’ portable computers .
小题2:.
. Few airlines want to refuse a total ban on their passengers because ____ .
A they have other effective safety measures to fall back on
B they don’t believe there is such a danger as radio interference
C the effect of electromagnetic interference is yet to be proved

举一反三
So when people tell us how wonderful we are,it makes us feel good.We long for this good feeling like a drug—we are addicted to it and seek it out wherever we can.Therefore,we are so eager for the approval(赞同)of others that we live unhappy and limited lives,failing to do the things we really want to.Just as drug addicts and alcoholics live worsened lives to keep getting their fix(一剂毒品),we worsen our own existence to get our own constant fix of approval.
But,just as with any drug,there is a price to pay.The price of the approval drug is freedom—the freedom to be ourselves. The truth is that we cannot control what other people think.People have their own agenda,and they come with their own baggage and,in the end,they’re more
interested in themselves than in you.Furthermore,if we try to live by the opinions of others,we will build our life on sinking sand.Everyone has a different way of thinking,and people change
their opinions all the time.The person who tries to please everyone will only end up getting exhausted and probably pleasing no one in the process.
So how can we take back control? I think there’s only one way—make a conscious decision to stop caring what other people think.We should guide ourselves by means of a set of values—not values imposed from the outside by others,but innate values which come from within.If we are driven by these values and not by the changing opinions and value systems of others,we will live a more authentic,effective,purposeful and happy life.
小题1:.What Oscar Wilde says implies that .
A.we have thoughts similar to those of others |
B.most people have a variety of thoughts |
C.other people’s thoughts are more important |
D.most people’s thoughts are controlled by others |
A.Changing opinions may cost us our freedom. |
B.We may lose ourselves to please others. |
C.We need to pay for what we want to get. |
D.The price of taking the drug is freedom. |
A. it’s better to do what we like |
B.we shouldn’t care what others think |
C.we shouldn’t change our own opinions |
D.it’s important to accept others’ opinions |
A.analyzing causes and effects | B.providing examples and facts |

A couple of years later, I was living in Jordan. I had just moved into a modern flat and was unpacking plates when I saw something move out of the corner of my eye. I looked over at the kitchen drawer and there was a cockroach(蟑螂)crawling out of it. I screamed. Then I grabbed a can of insecticide and sprayed it on the cockroach. He ran under the nearby bathroom door. It took me three days before I found the courage to open the bathroom door to see if he was still alive. He wasn’t.
Why did I react so violently to one lone insect when a closer encounter with hundreds of ants hardly affected me? The answer is easy: because cockroaches are creepy(令人毛骨悚然的) crawlies and ants aren’t. Creepy crawlies are those little bugs which cause feelings such as anxiety - they make your skin crawl.
Did you know that some people feel such a fear of bugs that it becomes a phobia(恐惧症)? Psychologists have offered many explanations. Some say we associate them with dirt and disease. Or that these are life forms that are so alien to us, that we find them disgusting for their dissimilarity.
Insects, however, don’t follow our rules - they just do what they want and invade our space. Unfortunately, although insects and bugs have been a successful animal species up to now, many of them, like many other species nowadays, are under threat of dying out. Entomologistswarn that this could upset entire ecosystems and lead to all kinds of disastrous consequences.
So my advice to you is: the next time you feel the urge to stamp on, splatter or spray a creepy crawly, give a thought to the planet and stop.
小题1:.. Why did the author mention the ants in the beginning?

C.liquid for killing insects | D.cleanser (洗涤剂)for the bathroom |
A.The author doesn’t mind the contact with those harmless small creatures. |
B.The author prefers cockroaches to ants and feels guilty for killing one. |
C.They invade our space and become a threat to humans. |
D.They still deserve a place for keeping the balance of the nature. |
A.Some people may be frightened so much by bugs that it leads to a psychological barrier to some degree. |
B.The earth will have a better and cleaner environment if more creepy crawlies are killed. |
C.Many bugs are in danger of dying out so we should not kill them due to fear or disgust. |
D.Some bugs are extremely unpleasant that some people have a strong wish to destroy them. |
“Psychologists’ explanations of the meaning of dreams vary widely. But our findings show that people believe their dreams provide meaningful insightinto themselves and their world,” said a lead author of the study Carey Morewedge, an assistant professor at Carnegie Mellon University.
In six different studies, researchers surveyed nearly 1,100 people about their dreams. One of the studies focused on general beliefs about dreams and involved 149 university students. All students were asked to rate different theories about dreams. The experts found that a surprising majority of the participants supported the theory about dreams revealing(揭示) the hidden truths about themselves and the rest of the world.
In a second experiment, they surveyed 182 people at a Boston train station, and asked them to imagine one out of four possible situation that could have occurred the night before a scheduled airline trip. Most of the participants said that dreaming of a plane crash would be more likely to affect their travel plans than would just thinking about a crash, or being warned by the government of a terrorism risk. They said a dreamed crash would influence their travel plans just as much as learning about a real crash on their planned route would.
Another experiment involved 270 men and women from across the United States. In a short online survey, they were asked to recall one of the dreams they had seen about any person they knew.
The findings showed that people were more likely to remember and describe pleasant dreams about a person they liked, rather than a person they disliked. Meanwhile, in most cases they tended to consider an unpleasant dream as more meaningful if it was about a person they disliked.
“In other words,” said Morewedge, “people attribute meaning to dreams when it corresponds (与……一致) with their pre-existing beliefs and desires.”
The researchers say that more investigation is needed to fully understand how people interpret their dreams. According to Morewedge, most people realize that dreams are not predicting their future, but they still try to find some meaning in there.
小题1:. The purpose of the studies is to .
A.determine when people tend to remember their dreams |
B.research whether dreams have anything to do with real life |
C.find out how people explain their dreams and what impact that has |
D.understand what causes people to dream and how to interpret dreams |
A.Thinking about a past plane crash. |
B.Dreaming about a plane crash. |
C.Hearing a government’s warning of a terrorism risk. |
D.Imagining a plane crashing on their planned route. |
A.Dreams can be a useful tool for learning and problem solving. |
B.Most people disagree that dreams help them better know themselves and the world. |
C.A majority of people believes that dreams can predict their future and try to find their meaning. |
D.When a dream conflicts with people’s existing beliefs and desires, they tend to attribute less meaning to it. |
A.A pleasant dream about a person the dreamer likes. |
B.A pleasant dream about a person the dreamer dislikes |
C.An unpleasant dream about a person the dreamer likes. |
D.An unpleasant dream about a person the dreamer dislikes. |
Scientific tests have shown that total silence can be a very frightening experience for a human being. However, some people enjoy listening to pop music which is very loud, and this can do harm to their eardrums(耳鼓). The noise level in some discos is far above the usual safety level for heavy industrial areas.
One recent report about noise and concentration suggested that although a lot of people say that any noise disturbs their concentration, what really influences their ability to concentrate is a change in the level of noise. It goes on to say that a background noise which doesn"t change too much (music, for example) may even help people to concentrate.
小题1:.
According to this passage, the noise pollution______.
A.has become the worst in the countryside |
B.has become better in big cities |
C.has spread from cities to villages |
D.has been controlled in modern cities |
What does background music refer to?
A.Music played while people are working. |
B.Music played in the backyard. |
C.Noise that continues while you’re listening to other noises. |
D.Music used to help people to concentrate. |
. Some people have their hearing harmed______.
A.while listening to pop music | B.in complete silence |
C.when speaking loudly | D.while watching TV |
The headmaster had gone away for the day, being a man who disliked the sight of changes. He did not mean to return till the evening, when the new teacher would have arrived, and everything would be smooth again.
The blacksmith, the farm bailiff and the teacher were standing in confused attitudes in the sitting room before the instrument. The teacher had remarked that even if he got it into the cart he should not know what to do with it on his arrival at Christminster, since he was only going into a temporary place just at first.
A little boy of eleven, who had been assisting in the packing, joined the group of men, and said, ‘Aunt has got a fuel-house, and it could be put there, perhaps, till you’ve found a place to settle in, sir.’
‘Good idea,’ said the blacksmith.
The smith and the bailiff started to see about the possibility of the suggested shelter, and the boy and the teacher were left standing alone.
‘Sorry I am going, Jude?’ asked the latter kindly.
Tears rose into the boy’s eyes. He admitted that he was sorry.
‘So am I,’ said Mr. Phillotson.
‘Why do you go, sir?’ asked the boy.
‘Well—don"t speak of this everywhere. You know what a university is, and a university degree? It is the necessary hallmark (标志) of a man who wants to do anything in teaching. My scheme, or dream, is to be a university graduate. By going to live at Christminster, I shall be at headquarters, so to speak, and if my scheme is practicable at all, I consider that being on the spot will afford me a better chance.’
The smith and his companion returned. Old Miss Fawley"s fuel-house was practicable; and she seemed willing to give the instrument standing-room there. So it was left in the school till the evening, when more hands would be available for removing it; and the teacher gave a final glance round.
At nine o"clock Mr. Phillotson mounted beside his box of books, and waved his friends good-bye.
小题1:It seemed that the teacher _____.
A.was not getting on well with the headmaster |
B.had lived a rather simple life in the village |
C.was likely to continue to practice playing the piano |
D.would get help in the city on arriving there |
A.ambition | B.devotion | C.admiration | D.inspiration |
A.polite, generous and cheerful | B.active, modest and friendly |
C.kind, bright and helpful | D.calm, confident and humorous |
A.love for music and his dislike for musical instruments |
B.hard work in the village and his strong interest in city life |
C.friendship with some villagers and also conflicts with others |
D.eagerness to go to the city and his affection for the village |
