We can make mistakes at any age. Some mistakes we make are about money. But most mistakes are about people. "Did Jerry really care when I broken up with Helen?" "When I got that great job did Jim really feel good about it, as a friend?" "Or did be envy my luck?" "And Paul-- why didn't I pick up that he was friendly just because I had a car?" When we look back, doubts like these can make us feel bad. But when we look back, it's too late.
Why do we go wrong about our friends or our enemies? Sometimes what people say hides their real meaning. And if we don't really listen, we miss the feeling behind the words. Suppose someone tells you, "You're a lucky dog." Is he really on your side? If he says, "You're a lucky guy" or "You're a lucky gal," that's being friendly. But "lucky dog" ? There's a bit of envy in those words. Maybe he doesn't see it himself. But bringing in the "dog" bit puts you down a little. What be may be saying is that be doesn't think you deserve your luck.
"Just think of all the things you have to be thankful for" is another noise that says one thing and means another. It could mean that the speaker is trying to get you to see your problem as part of you life as a whole. But is he? Wrapped up in this phrase is the thought that your problem isn't important. It's telling you to think of all the starving people in the world when you haven't got a date for Saturday night.
How can you tell the real meaning behind someone's words? One way is to take a good look at the person talking. Do his words fit the way he looks? Does what he says square with the tone of voice? His posture? The look in his eyes? Stop and think. The minute you spend thinking about the real meaning of what people say to you may save another mistake.
Note: guy = boy; gal = girl
In paragraph 1, when the writer recalls some things that happened between him and his friends, ______.
A.he feels happy, thinking of how nice his friends were to him.
B.he feels he may not have "read" his friends' true feelings correctly.
C.he thinks it was a mistake to have broken up with his girlfriend.
D.he is sorry that his friends let him down.

One day I can hear the faint rustle of autumn coming. The next day I can’t. One evening summer leaks away into the cool night sky, but the next morning it’s back again. But there is headway. Birdsong has gone, and is【46】______ (replace) by a whining bag-piping of insect creation. I look out across the pasture as dusk【47】______(begin) and see a shining galaxy of airborne bugs. What would it be like, I wonder, to have an【48】aware______of the actual number of insects on this farm?
I ask myself a version of this question every day: "Have you ever really looked at…?”You can【49】______in the blank yourself.
Every day I am blinded by【50】familiar______. I open our beehive, which is filled with honey, and the particularity of the honeybees, and even of their community, somehow escapes me, if only because I’ve been living with honeybees a good part of my life. I remember the phrase, "keep your eyes【51】______ (peel) , ”and maybe that’s what I need, a good peeling.
Again and【52】______, I find myself trying to really look at what I' m seeing. It happened the other afternoon, high on a nearby mountain. A dragonfly had settled on the denuded tip of a pine bough. It clung, still as only a dragonfly can be. Then it flicked upward and caught a midge and settled on the bough again, adjusting【53】______(precise) to the wind. I see dragonflies【54】______ (quiver) in the insect clouds above my pasture, too. I am always aware, however , that there’s no such thing as really looking.
What I want to see is invisible anyway: the prehistoric depth of time embodied in the form. of those dragonflies, the pressure of life itself, the web of【55】______(relate) that bind us all together. I find myself trying to【56】wit______the moment when the accident of life becomes a continued purpose. But this is a small farm, and, being human, 1 keep【57】______(come) up against the limits of what a human can see.
This morning I found a spider resting—or perhaps hunting—on the leaf of a hydrangea, the axis of the spider’s abdomen perfectly aligned with the axis of the leaf. What I noticed was the symmetry of their placement, the way spider, and leaf resembled【58】_____other. What I wanted to determine was the spider’s intent. If I【59】c______, I would have asked it, "What are you doing?” Or, better yet, "Who are you?” But all I could do was look—and realizing that I was looking—make the【60】b______of what I’d seen.

听力原文:M: Well, a business Angel sounds like someone who is unselfish, but in fact it expects to make a good return on their money. We usually invest in start-ups and small businesses looking to expand. When the company does well we expect our capital back with a substantial return. These investments are different from bank loans in the way that I don't charge interest, so I'm taking a risk with my money.But within five years I expect to get a good return on this investment——about fifty or sixty percent.Earlier this year I got back ten times the amount I'd invested in one company.

Pepys and his wife Jane had asked some friends to dinner on Sunday, September 2nd, 1666.They were up very late on the Saturday evening, getting everything ready for the next day, and while they were busy they saw the glow(微弱的光) of a fire start in the sky. By 3 o'clock on the Sunday morning, its glow had become so bright that Jane woke her husband to watch it. Pepys slipped on his dressing-gown and went to the window to watch it. It seemed fairly far away, and after a time he went back to bed. When he got up in the morning, it looked, though the fire was dying down, as though he could still see some flames. So he set to work to tidy his room and put his things back where he wanted them.
While he was doing this, Jane came in to say that she had heard the fire was a bad one; hundreds of houses had been burned down in the night and the fire was still burning. Pepys went out to see for himself. He went to the Tower of London and climbed upon a high part of the building so that he could see what was happening. From there, Pepys could see that it was, indeed, a bad fire and that even the houses on London Bridge were burning. The man of the Tower told him that the fire had started in a baker's.shop in Pudding Lane(小巷) ; the baker's house had caught fire from the over-heated oven(烤箱) and then the flames had quickly spread to the other houses in the narrow lane. So the Great Fire of London, a fire that lasted nearly five days, destroyed most of the old city and ended, as it is said, at Pie Comer.
What is the passage about?
A.The Great Fire of London.
B.Who was the first to discover the fire.
C.What Pepys was doing during the fire.
D.The losses caused by the fire.

The next time the men were taken up onto the deck, Kunta made a point of looking at the man behind him in line, the one who lay beside him to the left when they were below. He was a Serer tribesman much older than Kunta, and his body, front and back, was creased with whip cuts, some of them so deep and festering that Kunta, felt badly for having wished sometimes that he might strike the man in the darkness for moaning se steadily in his pain. Staring back at Kunta, the Serer's dark eyes were full of fury and defiance. A whip lashed out even as they stood looking at each other—this time at Kunta, spurring him to move ahead. Trying to roll away, Kunta was kicked heavily in his ribs. But somehow he and the gasping Wolof managed to stagger back up among the other men from their shelf who were shambling toward their dousing with bucked of seawater.
A moment later, the stinging saltiness of it was burning in Kunta's wounds, and his screams joined those of others over the sound of the drum and the wheezing thing that had again begun marking time for the chained men to jump and dance for the toubob. Kunta and the Wolof were so weak from their new beating that twice they stumbled, but whip blows and kicks sent them hem hopping clumsily up and down in their chains. So great was his fury that Kunta was barely aware of the women singing "Toubob fa!" And when he had finally been chained hack down in his place in the dark hold, his heart throbbed with a lust to murder toubob.
Every few days the eight naked toubob would again come into the stinking darkness and scrape their tubs full of the excrement that had accumulated on the shelves where the chained men lay. Kunta would lie still with his eyes staring balefully in hatred, following the bobbing orange lights, listening to the toubob cursing and sometimes slipping and tailing into the slickness underfoot—so plentiful now, because of the increasing looseness of the men's bowels, that the filth had begun to drop off the edges of the shelves down into the aisleway.
The last time they were on deck, Kunta had noticed a man limping on a badly infected leg. This time the man was kept up on deck when the rest were taken back below. A few days later, the women told the other prisoners in their singing that the man's leg had been cut off and that one of the women had been brought to tend him, but that the man had died that ,fight and been thrown over the side. Starting then, when the toubob came to clean the shelves, they also dropped red-hot pieces of metal into pails of strong vinegar. The clouds of acrid steam left the hold smelling better, but soon it would again be overwhelmed by the choking stink. It was a smell that Kunta felt would never leave his lungs and skin.
The steady murmuring that went on in the hold whenever the toubob were gone kept growing in volume and intensity as the men began to communicate better and better with one another. Words not understood were whispered from mouth to ear along the shelves until someone who knew more then one tongue would send back their meaning. In the process, all of the men along each shelf learned new words in tongues they had not spoken before. Sometimes men jerked upward, bumping their heads, in the double excitement of communicating with each other and the fact that it was being done without the toubeb's knowledge. Muttering among themselves for hours, the men developed a deepening sense of intrigue and of brotherhood. Though they were of different villages and tribes, the feeling grew that they were not from different peoples or places.
The living conditions for the Blacks in the salve ship were ______.
A.adequate but primitive
