One of the qualities that most people admire in others is the willingness to admit one's mistakes. It is extremely hard sometimes to say a simple thing like "I was wrong about that," and it is even harder to say, "I was wrong, and you were right about that."
I had an experience recently with someone admitting to me that he had made a mistake fifteen years ago. He told me he had been the manager of a certain grocery store in the neighbourhood where I grew up, and he asked me if I remembered the egg boxes. Then he related an incident and I began to remember vaguely the incident he was describing.
I was about eight years old at the time, and I had gone into the store with my mother to do the weekly grocery shopping. On that particular day, I must have found my way to the dairy food department where the incident took place.
There must have been a special sale on eggs that day because there was an impressive display of eggs in dozen and half-dozen boxes. The boxes were stacked three or four feet high. I must have stopped in front of a display to admire the stacks. Just then a woman came by pushing her grocery cart and knocked off the stacks of boxes. For some reason, I decided it was up to me to put the display back together, so I went to work.
The manager heard the noise and came rushing over to see what had happened. When he appeared, I was on my knees inspecting some of the boxes to see if any of the eggs were broken, but to him it looked as if I was the culprit (做错事的人). He severely scolded me and wanted me to pay for any broken eggs. I tried to explain it wasn’t me who had broken them, but it did no good. Even though I quickly forgot all about the incident, obviously the manager did not..

Ever wonder how much a cloud weighs? What about a hurricane? A meteorologist(气象学者) has done some estimates and the results might surprise you.
Let's start with a very simple white puffy cloud — a cumulus cloud(积云). How much does the water in a cumulus cloud weigh? Peggy LeMone, senior scientist at the National Center for Atmospheric Research in Boulder, Colorado, did the numbers. "The water in the little cloud weighs about 550 tons," she calculates. "Or if you want to convert it to something that might be a little more meaningful … think of elephants."
The thought of a hundred elephants-worth of water suspended(悬浮的) in the sky begs another question — what keeps it up there?
"First of all, the water isn't in elephant-sized particles(微粒), it's in tiny tiny tiny particles," explains LeMone. And those particles float on the warmer air that's rising below. But still, the concept of so much water floating in the sky was surprising even to a meteorologist like LeMone. "I had no idea how much a cloud would weigh, actually, when I started the calculations," she says.
So how many elephant units of water are inside a big storm cloud—10 times bigger all the way around than the "puffy" cumulus cloud? Again, LeMone did the numbers: About 200,000 elephants.
Now, ratchet up(略微调高) the calculations for a hurricane about the size of Missouri and the figures get really massive(巨大的). "What we're doing is weighing the water in one cubic meter theoretically pulled from a cloud and then multiplying by(乘上) the number of meters in a whole hurricane," she explains.
The result? Forty million elephants. That means the water in one hurricane weighs more than all the elephants on the planet. Perhaps even more than all the elephants that have ever lived on the planet. The weight of is NOT mentioned in the passage.
| A.a cumulus cloud | B.a tornado |
| C.a hurricane | D.a storm cloud |
How did Peggy LeMone feel about the result of her calculations?
| A.She found it not convincing. |
| B.She thought it needed further calculations. |
| C.She was quite surprised at it. |
| D.She considered the calculations inaccurate. |
What can be inferred from the passage?
| A.A storm cloud weighs about 200,000 elephants. |
| B.The water in a hurricane weighs more than that in any other kind of cloud. |
| C.There are less than forty million elephants living on the earth. |
| D.The water in the cloud is in very tiny partials. |
What is the best title for the passage?
| A.How Much a Cloud Weighs | B.How Much a Hurricane Weighs |
| C.Surprising Results | D.Elephants in the Sky |
If you hear the sound of running water the next time you call a co-worker on his or her mobile phone, don’t be surprised. Three-fourths of Americans with mobile phones say they use them in the bathroom, a new study shows.
Approximately(大约) the same number of men and women have used the phone in the bathroom, according to a survey of 1,000 Americans by 11 mark, an integrated marketing agency, although men seem more attached to IT in the toilet: 30 percent of men versus(VS) 20 percent of women agreed with the statement, "I don't go to the bathroom without my mobile phone."
More than half the surveyed users (63 percent) said they have answered a phone call in the bathroom, and almost half (41 percent) reported initiating a phone call. That's not all, however. What goes on behind the walls of the stalls(小隔间) is anything a mobile phone is capable of. Sixty-seven percent said they have read a text, and 39 percent have surfed the Web. Men work more from the bathroom — 20 percent said they have participated in work-related calls, versus 13 percent of their female colleagues.
As expected, Gen Y(1981年后出生的一代) respondents(调查对象) are the pacesetters(先导者) in the "mobile everywhere" movement, with 91 percent using their phone in the bathroom. Still, older generations are not far behind. Eighty percent of Gen X(1961-1981) reported using the phone in the bathroom, as did 65 percent of Baby Boomers(1946-1965) and 47 percent of the Silent Generation(1925-1945).
While online, they are doing more than just surfing; 16 percent of Gen Y report they have made an online purchase while in the bathroom. Users of iPhones are particularly likely to browse and buy in the bathroom – 22 percent have made a purchase, versus 10 percent of Americans with mobile phones overall.
"The writing is on the stall," said 11 mark principal Nicole Burdette. "This study confirms what we all know: that the last private place is no longer private."
In the process, high-tech hygiene(卫生) is taking a hit, the survey found. While 92 percent of mobile phone users said they wash their hands after using the bathroom, only 14 percent said they wash their phones.Which is the best word to replace the underlined word "initiating"?
| A.receiving | B.experiencing | C.ending | D.beginning |
According to his words, Nicole Burdette mainly wants to tell us that .
| A.no wonder mobile phones are used in the bathroom |
| B.the bathroom is a private place for people |
| C.it makes people have no privacy at all |
| D.more men have used the phone in the bathroom |
What does the last paragraph of the passage imply?
| A.Using phones in the bathroom has a bad effect on hygiene |
| B.Mobile phones should not be allowed to use in the bathroom |
| C.Most people care about the hygiene after using the bathroom |
| D.Few people wash their phones after using the bathroom |
The attitude of the author to the use of phones in the bathroom is ______
| A.supportive | B.disapproval | C.subjective | D.objective |
In July 1994 Jupiter, the largest planet in our solar system, was struck by 21 pieces of a comet (彗星). When the fragments (碎片) landed in the southern part of the giant planet, the explosions(爆炸) were watched by scientists here on the earth. But what if our own planet was hit by a comet?
The year is 2094. It has been announced that a comet is heading towards the Earth. Most of it will miss our planet, but two fragments will probably hit the southern part of the Earth. The news has caused panic.
On 17 July, a fragment, four kilometers wide, enters the Earth's atmosphere with a huge explosion. About half of the fragment is destroyed. But the major part survives and hits the South Atlantic at 200 times the speed of sound. The sea boils and an enormous(巨大的) wave is created and spreads. The wall of water rushes towards southern Africa at 800 kilometres an hour. Cities on the African coast are totally destroyed and millions of people are drowned. The wave moves into the Indian Ocean and heads towards Asia.
Millions of people are already dead in the southern part of the Earth, but the north won't escape for long. Tons of broken pieces are thrown into the atmosphere by the explosions. As the sun is hidden by clouds of dust, temperatures around the world fall to almost zero. Crops are ruined. Wars break out as countries fight for food. A year later civilization has collapsed(崩溃). No more than 10 million people have survived.
Could it really happen? In fact, it has already happened more than once in the history of the Earth. The dinosaurs were on the Earth for over 160 million years. Then 65 million years ago they suddenly disappeared. Many scientists believe that the Earth was hit by a space fragment. The dinosaurs couldn't survive in the cold climate that followed and they became extinct. Will we meet the same end?Which of the following is NOT TRUE according to the author's description of the disaster in 2094?
| A.The whole world becomes extremely cold |
| B.All the coastal cities in Africa are destroyed |
| C.The visit of the comet results in wars |
| D.The whole mankind becomes extinct |
Why does the author mention dinosaurs at the end of the passage?
| A.Because they could only live in the warm climate |
| B.Because their extinction indicates future disasters |
| C.Because they once dominated(控制) the earth |
| D.Because dinosaurs and humans never live in the same age |
In writing the passage, the author intends to ______.
| A.give an accurate description of the possible disaster in the future |
| B.prove that humans will sooner or later be destroyed |
| C.warn of a possible disaster in the future |
| D.tell the historical development of the Earth |
It can be concluded that the passage is most probably part of a(n) ______.
| A.article of popular science | B.news report |

I was waiting for a phone call from my agent. He had left a message the night before, telling me that my show was to be cancelled. I called him several times, but each time his secretary told me that he was in a meeting and that he would call me later. So I waited and waited, but there was still no call. Three hours passing by, I became more and more impatient. I was certain that my agent didn’t care about my work, and he didn’t care about me. I was overcome with that thought. I started to shout at the phone, “Let me wait, will you? Who do you think you are?”
At that time I didn’t realize my wife was looking on. Without showing her surprise, she rushed in, seized the phone, tore off the wires, and shouted at the phone, “Yeah! Who do you think you are? Bad telephone! Bad telephone! ” And she swept it into the wastebasket.
I stood watching her, speechless. What on earth…?
She stepped to the doorway and shouted at the rest of the house, “Now hear this! All objects in this room——if you do anything to upset my husband, out you go!”
Then she turned to me, kissed me, and said calmly, “Honey, you just have to learn how to take control.” With that, she left the room.
After watching a crazy woman rushing in and out, shouting at everything in sight, I noticed that something in my mood had changed. I was laughing. How could I have trouble with that phone?

In the near future,we may be using our eyes to operate our smart-phones and tablets,even when it comes to playing popular games like Fruit Ninja.
The Gaze Group has been developing eye-controlled computer technology for nearly 20 years.But those devices have been firstly designed to help those with disabilities,and are very expensive.
“After a while,we figured out that probably the best way is to go for a mass-market way,” says Gaze’s Sune Alstrup Johansen.“where everybody would have this available."
Johansen and some of his colleagues have formed a new company,the Eye Tribe,which is hoping to develop the technology on a mass commercial level.
The technology works with the help of the computing device toward the user’s face. After making sure of the user’s eye movements,the technology is then able to easily find where a person’s eyes are moving,and then allow the eyes to control a cursor(光标).
“Our software can then determine the location of the eyes and know where you’re looking on the screen to make sure what you’re looking at,“reads an explanation on the Eye Tribe site.
There has been a gradual change toward hands-free technology in recent years, particularly in the gaming world.Recently Xbox released the Kinect device,which lets users control their Xbox and play certain games using only their hands,legs and voices. But still,most of these devices have been more of a gimmick than a practical way to use one’s hands to control a mobile device.Johansen said a replaceable filter(滤光器)would be a cheap,convenient way for most consumers.
And even as companies like The Eye Tribe work to create such a product for the average user, making the eye-controlled technology more accessible and less expensive will have similar benefits for physically disabled users.
