I give two examples as to why intelligent life may not actually exist, though I admit that for me, or even for a physicist who devoted his or her entire life to researching and studying the universe, it's shocking to claim that completely no life exists elsewhere.
Keeping that in mind, I'd just like to consider conditions elsewhere in the known universe. You really only need to look at our own solar system or the Earth at certain periods in its own history to appreciate that most places are much worse and much less suitable for life than our mild, watery globe.
So far, space scientists have discovered about seventy planets outside the solar. But it appears that if you wish to have a planet suitable for life, you just have to be very lucky, and the more advanced the life is, the luckier you'll have to be. I'm by no means a space observer, but I can recognize some particularly fortunate breaks we've had on the Earth. For example:
We are, to a degree, at the right distance from the perfect type of star, the one that is big enough to radiate a huge amount of energy, but not so big as to bum itself out quickly. Had our sun been ten times as huge, it would have burnt out completely after only ten million years, instead of ten billion and surely we would not exist. Too near, everything on the Earth would have boiled and withered away; any further, everything would have frozen over.
The universe is a surprising place, and our existence within it is a wonder. If a long and unimaginably complex sequence of events dating back 4.6 billion years or so hadn't happened in a particular manner at a particular time --if, to take just one example, the dinosaurs hadn't been wiped out by a meteor(流星)--we might still be a few centimeters long, with whisker(胡须) and a tail, and you'll be reading this in a cave somewhere.What's the best title for this passage?
| A．No Life Exists out of the Earth |
| B．Seventy Planets Discovered |

The Great Gatsby is a 1925 novel written by American author F. Scott Fitzgerald that follows a cast of characters living in the fictional town of West Egg on Long Island in the summer of 1922.
Nick Carraway rents a small house in West Egg on Long Island, next door to the expensive house of Jay Gatsby, a mysterious millionaire who often holds extravagant（奢侈的）parties. Nick’s cousin, Daisy, and her husband, Tom, a college classmate of Nick’s, live in East Egg across the bay.
Nick later learns that Gatsby knew and fell in love with Daisy in 1917 and is still deeply in love with her. He spends many nights staring at her house across the bay from his house, hoping to recover their lost relationship one day. Gatsby’s extravagant lifestyle and wild parties are an attempt to impress Daisy in the hope that she will one day appear again at Gatsby’s doorstep. With the help of Nick, Gatsby and Daisy get in touch again. But after a short time, Tom forces the group to drive into New York City, saying that he and Daisy have a history that Gatsby could never understand. In addition, he announces that Gatsby is a criminal whose fortune comes from illegal activities. Daisy realizes that her allegiance（忠心）is to Tom, and Tom sends her back to East Egg with Gatsby, attempting to prove that Gatsby cannot hurt him.
When Nick and Tom drive home, they discover that Gatsby’s car has struck and killed Myrtle. Nick later learns from Gatsby that Daisy, not Gatsby himself, was driving the car at the time of the accident but Gatsby intends to take the blame anyway. Myrtle’s husband, George, arrives at Gatsby’s house and fatally（致命地）shoots both Gatsby and then himself.
Nick stages a small funeral for Gatsby with few coming to mourn the passing of his romantic dream. After that, Nick moves back to the Midwest, disillusioned（幻灭）with the Eastern lifestyle.
At first glance, the novel appears to be a simple love story, but further examination shows Fitzgerald’s masterful observation of American society during the 1920s and the corruption（堕落）of the American dream.

When tea was first brought to England between 1652 and 1654, it was so expensive that only the rich could buy it. It was said that an old couple had some sent to them as a great treat. But they did not know how it ought to be used. Eventually they boiled the leaves, put some of them on a piece of bacon for dinner, ate the leaves, and threw the tea soup away. However, tea quickly proved popular enough to replace ale（麦芽酒）as the national drink of England after King Charles II and his Portuguese wife began to follow this foreign tea tradition.
Before the introduction of tea into Britain, the English had two main meals — breakfast and dinner. Breakfast was ale, bread and beef. Dinner was a long, massive meal at the end of the day. It was no wonder that Anna, the Duchess of Bedford (1788 — 1861) experienced a “sinking feeling” in the late afternoon. So she invited friends to join her for an additional afternoon meal at five o’clock in her castle. The menu centered around small cakes, bread and butter sandwiches, and, of course, tea. This summer practice proved so popular that the Duchess continued it when she returned to London, sending cards to her friends asking them to join her for “tea and a walking the fields”.
The practice of inviting friends to come for tea in the afternoon was quickly picked up by other social hostesses. A common pattern of service soon came into practice. The first pot of tea was made in the kitchen and carried to the lady of the house who waited with her invited guests, surrounded by fine porcelain（瓷器）from China. The first pot was warmed by the hostess from a second pot (usually silver) that was kept heated over a small flame. Food and tea was then passed among the guests, the main purpose of the visiting being conversation.The story of the old couple in Paragraph 1 is to show ____________.
| A．how impolite the old couple were |
| B．how English people cooked tea |
| C．how difficult it was to introduce tea to England |
| D．how little English people knew about tea in those days |
The underlined phrase “sinking feeling” in Paragraph 2 refers to a feeling of ____________.
| A．hunger | B．loneliness |
| C．thirst | D．anger |
According to the passage, the key factors of a typical afternoon tea include ____________.
a. cakes and bread
b. a massive meal

e. fine porcelain
f. silver tea pot
g. a small flame
| A．a, b, c, d, f | B．a, c, e, f, g |

【改编】Is language, like food, a basic human need without which a child at a critical period of life can be starved and damaged? Judging from the experiment of Frederick in the thirteenth century, it may be. Hoping to discover what language a child would speak if he heard no mother tongue, he told the nurses to keep silent.
All the infants died before the first year. But clearly there was more than lack of language here. What was missing was mothering. Without good mothering, in the first year of life especially, the capacity to survive is seriously affected.
Today no such severe lack exists as that ordered by Frederick. Nevertheless, some children are still backward in speaking. Most often the reason for this is that the mother is insensitive to the signals of the infant, whose brain is programmed to learn language rapidly. If these sensitive periods are neglected, the ideal time for acquiring skills passes and they might never be learned so easily again. A bird learns to sing and to fly at the right time, but the process is slow and hard once the critical stage has passed.
Experts suggest that speech stages are reached in a fixed order and at a constant age, but there are cases where speech has started late in a child who eventually turns out to be of high IQ. At twelve weeks a baby smiles and makes vowel-like sounds; at twelve months they can speak simple words and understand simple commands; at eighteen months he has a vocabulary of three to five words. At three he knows about 1,000 words, which he can put into sentences, and at four his language differs from that of his parents in style rather than grammar.
Recent evidence suggests that an infant is born with the capacity to speak. What is special about man’s brain, compared with that of the monkey, is the complex system which enables a child to connect the sight and feel of, say, a toy-bear with the sound pattern “toy bear”. And even more incredible is the young brain’s ability to pick out an order in language from the mixture of sound around him, to analyze, to combine and recombine the parts of a language in new ways.
But speech has to be induced（激发，引起）, and this depends on interaction between the mother and the child, where the mother recognizes the signals in the children’s babbling（咿呀声）,grasping and smiling, and responds to them. Insensitivity of the mother to these signals dulls the interaction because the child gets discouraged and sends out only the obvious signals. Sensitivity to the child’s nonverbal signals is essential to the growth and development of language.The experiment of Frederick proved ____.
| A．lack of mothering didn’t affect the development of a baby |
| B．only lack of language could kill a baby |
| C．very cruel to the babies in the experiment |
| D．babies could be starved to death |
Why are some children backward in speaking?

| B．Because they lack language input when in sensitive periods. |
| C．Because they are exposed to too much language at once. |
| D．Because their mothers are not smart enough |
Which of the following is true ?
| A．If a child starts to speak later than others, he will be backward in future. |
| B．If the ideal time for acquiring skills passes, there will be a second time. |
| C．A child can only imitate others’ language. |
| D．An infant is born with the ability to speak. |
What is the purpose of the example of birds in the third paragraph?
| A．To prove the importance of the sensitive periods. |
| B．To prove birds has the same ability to speak as human. |
| C．To explain why some birds can’t sing. |
| D．To inform the results of Frederick’s experiment. |

Human beings are the most intelligent of all animals because we are gifted with the ability to think and reason logically. Scientists and even common people with special intelligence have made a lot of inventions and contributions to modern lifestyle in the past. "Houses" have been the most popular area for discoveries and inventions in the past and even now.
Many household items have been the result of inventions of people who desired better functioning of the existent products. Every individual has intelligence and if it is used properly for the right purpose it leads to invention of a new tool or device. Many new household inventions are made almost every day and there are specific companies, which particularly keep a record of all these inventions.
A lot of inventions have been made recently in the household field. These products are patentedand have trade mark licenses. The patented sliding cinch is a very simple but effective method to prevent shoulder stress and injury for those who work before computers all day long. Vanity PC is a type of computer furniture that specifically hides all the computer wires and keeps a clean and good look. All the outdoor dust, mud and snow can be kept out of the house by installing（安装）the dirt drain（排水管）at the entrance of the door. Another important invention is the automatic toilet night-light, in which a small light starts when the lid of the toilet seat is opened and closes as soon as the lid is closed.
These are some of the new household inventions invented mostly by common people. Thus, a variety of new household items are invented every day, which helps in a better functioning of household chores（家务）and in a more useful manner.The first paragraph is intended to _____________.

【改编】What is funny? The short answer is: Who knows? The joke that causes a burst of laughter from one listener might be met with a puzzled look from another.
In general, you should avoid jokes at any business or social gathering where there are more than two people in your conversational group. If there are only two people — and they consist of you and your best friend — go ahead and tell it.
Admittedly, a few people possess a perfect sense of timing, appropriateness, and joke delivery. You are probably not one of them. You might be quite funny and have many great jokes. But there’s a place for jokes — over dinner with family, hiking with friends, but business or social affairs with colleagues and acquaintances (熟人) are not it. It takes a whole other level of joke-telling ability to put a joke into the more formal conversations.
The best jokes come into the conversation so that by the time listeners realize a joke is in progress, the punchline that produces humour is being delivered — to their surprise and delight.
Jokes don’t translate well when you’re in a group with mixed backgrounds: those whose first language is not English, those who might not understand a special term or an “in” expression, young people who wouldn’t catch a reference to some bit of culture familiar to older people — and vice versa (反之亦然).
Never joke about another person in the group — about their name, habits, hometown, profession, appearance, or past. It’s not a question of whether the joke is cheery or appropriate. No one enjoys being singled out this way. When you are the subject of the joke, the laughter doesn’t feel good no matter how hard you try to tell yourself they’re not laughing at you. Because that’s what it feels like.
What do you say if you realize your joke upset someone? Apologize as briefly and as sincerely as you can, and hope that someone changes the subject. Try saying: “I’m sorry. I should have known better” or “I’m sorry. I wasn’t thinking.”
What do you do if people don’t get your joke or don’t appear to find it as funny as you do? First, do not retell it, only louder this time, hoping the point of the joke will be seen. Second, don’t try to push people to get it. People do not like people whose jokes they don’t understand. They feel stupid and need to blame someone. If you want to leave with the goodwill of your listeners, say something to make them feel less foolish. You could say: “I don’t know why I tell jokes when I’m so poor at it.”
The world needs laughter, and good humour is a success wherever it goes, so this caveat (告诫) about joke-telling is not meant to dampen high spirits or to advocate dull conversation. If you’re a gifted story-teller and you know people love your jokes, go for it. We need your kind. The rest of us will save our jokes for family and close friends.From the first paragraph we can know______.
