IS THERE LIFE ON EARTH
There was great excitement on the planet of Venus(金星) this week. For the first time Venusian scientists managed to land a satellite on the planet Earth, and it has been sending back signals as well as photographs ever since.
The satellite was directed into an area known as Manhattan (named after the great Venusian astronomer Prof. Manhattan, who first discovered it with his telescope 20 000 light years ago).Because of excellent weather conditions and extremely strong signals, Venusian scientists were able to get valuable information as to feasibility(可行性) of a manned flying saucer(飞碟) landing on Earth.A press conference was held at the Venus Institute of Technology.
“We have come to the conclusion,based on last week's satellite landing,” Pro. Zog said,“that there is no life on the Earth.”
“How do you know this?” the science reporter of the Venus Evening Star asked.
“For one thing, Earth's surface in the area of Manhattan is composed of solid concrete(混凝土)and nothing can grow there. For another, the atmosphere is filled with carbon monoxide(一氧化碳) and other deadly gases and nobody could possibly breathe this air and survive.”
“What does this mean as far as our flying saucer program is concerned?”
“We shall have to take our own oxygen with us, which means a much heavier flying saucer than we originally planned. ”
“Are there any other hazards that you discovered in your studies?”
“Take a look at this photo. You see this dark cloud floating over the surface of Earth? We call this the Consolidated Edison Belt. We don't know what it is made of, but it could give us a lot of trouble and we shall have to make further tests before we send a Venus Being there.”
“If what you say is true, won't this set back the flying saucer program several years?”
“Yes, but we shall proceed as soon as the Grubstart gives us the added funds.”
“Prof. Zog, why are we spending billions and billions of zilches to land a flying saucer on Earth when there is no life there?”
“Because if we Venusians can learn to breathe in an Earth atmosphere, then we can live anywhere.”During the week of great excitement the Venusian scientists succeeded in getting important information on whether they can_______.
| A．land a satellite with Venus astronauts on Earth |
| B．make a firstrate flying saucer |
| C．get a Earth Being to Venus |
| D．direct a flying saucer into Manhattan |
According to Prof.Zog,the Venusians will have to take their own oxygen with them when they carry out their flying saucer program because_______.
| A．they need it on their way to the planet of Earth |
| B．the Earth's atmosphere is filled with deadly gases |
| C．oxygen is far from enough in the area of Manhattan where the saucer is to land |
| D．there is no air on the planet of Earth |
The “dark black cloud” on the photograph refers to_______.
| A．the polluted air floating over the surface of Earth |
| B．the mass of tiny drops of water floating above Earth |
| C．the things that are unknown to everybody |
| D．the dark clouds gathering before a storm breaks |
The author wishes to call our attention to the fact_______.
| A．that modern man has polluted his environment to such an extent that he might destroy himself if he went on like this |
| B．that there is no point in spending billions and billions of zilches to land a flying saucer on Earth |
| C．that pollution has become so serious a problem on Earth that even Venusians find life there unbearable |
| D．that it is difficult, if not altogether impossible, to land a manned flying saucer on Earth |
Animals can move from place to place, but plants cannot. When an animal is under attack, it can run away or fight back. Plants certainly cannot run away, and they lack teeth and claws. But plants can defend themselves by using both physical and chemical means.
Some plants have their own ways to keep animals away. For example, the leaves of the holly plant have sharp spines (刺) that discourage grass-eating animals. Holly leaves on lower branches have more spines than leaves on upper branches. This is because the lower leaves are easier for most animals to reach.
Some plants, such as the oak tree, have thick and hard leaves that are difficult for animals to eat. Some grasses may contain a sandy material; eating such grasses wears down the animal's teeth.
Many plants also have chemical defenses. Some plants produce chemicals that taste bitter or cause an unpleasant reaction. Some plants may fight against an attack by increasing the production of these chemicals. When a caterpillar (毛虫) bites a tobacco leaf, the leaf produces a chemical messenger. This messenger sends to the roots the information to produce more nicotine. The higher levels of nicotine discourage the caterpillar.
Many plants depend on both physical and chemical defenses. A certain plant in China, for instance, has prickly (多刺的) leaves, and each prickle contains poisonous venom (毒液). A single experience with this kind of plant will teach an animal to stay away from it in the future.The holly plant has more spines on the lower leaves because most animals________.
| A．are not tall enough | B．like the lower leaves only |
| C．are not clever enough | D．can get the lower leaves easily |
To defend themselves, oak trees use________.
| A．chemical means | B．physical means |
| C．bitter chemicals | D．sandy materials |
How does tobacco protect itself against an attack from a caterpillar?
| A．Its leaves fight against the attack by physical means. |
| B．Its roots send a messenger to discourage the caterpillar. |
| C．Its roots increase the production of nicotine when it is attacked. |
| D．Its leaves produce poisonous sand to drive the caterpillar away. |
What would be the best title for this passage?
| A．Plants and Animals | B．How Plants Defend Themselves |
| C．Attacks and Defenses | D．How Animals Eat Plant Leaves |

SEE a cell phone cover that you like on Taobao? Forget about placing an order, paying the bill online and waiting for days for it to be delivered to you. In the near future, you'll be able to get it in minutes just by hitting "print" on your computer.
You might find it hard to believe that you could actually "print" an object like you would a picture.But it is not that hard to understand how it would work. Just as a traditional printer sprays (喷) ink onto paper line by line, modern 3-D printers spread material onto a surface layer by layer, from the bottom to the top, gradually building up a shape.
Instead of ink, the materials the 3-D printer uses are mainly plastic, resin (树脂)and certain metals. The thinner each layer is --- from a millimeter to less than the width of a hair --- the smoother and finer the object will be.
This may sound like a completely new technology, but the truth is that 3-D printing has been around since the late 1980s. Back then, it was barely affordable for most people, so few knew about it.
Last year, though, saw a big change in the 3-D printing industry--- printers became much cheaper. For example, 10 years ago a desktop 3-D printer might have cost £20,000 (200,000 yuan), while now they cost only about £ 1,000, according to the BBC.
Taken out of the factory and introduced to more diverse and common uses, 3-D printing can create just about anything you can think of ---flutes (笛子), bikinis, jewelry, aircraft parts and even human organs. In fact, scientists from Cornell University in New York have just made an artificial ear using a 3-D printer, according to Science Daily. The fake ear looks and acts exactly like a natural one.
However, as 3-D printing becomes more commonplace, it may bring about certain problems --- such as piracy. "Once you can download a coffee maker, or print out a new set of kitchen utensils (餐具) on your personal 3-D printer, who will visit a retail (零售的) store again?" an expert in 3-D printing told Forbes News. Even more frightening, what if anyone in the world could use a 3-D printer to print out a fully functioning gun?According to the article, in the future, the 3-D printing technology will ___.
| A．enable people to make better purchases online |
| B．be applied as widely in our daily lives as computers |
| C．change the way we make many products |
| D．shorten the time it takes for people to get what they buy online |
What was the big event happening in the 3-D printing industry last year?
| A．The 3-D printing technology was taken out ofthe factory. |
| B．The 3-D printer became more affordable forconsumers. |
| C．The 3-D printer was used for medical treatmentfor the first time. |
| D．3-D printing technology began to be used invarious fields. |
How is the last paragraph developed?
| A．By analyzing a cause and an effect. | B．By making comparisons. |
| C．By giving examples. | D．By presenting research findings. |
What is the best title of the passage?
| A．Printing out everything | B．Technology in the future |
| C．Online shopping disappearing | D．Great demand for 3-D printers |

A Winter Adventure
Beep, beep. Beep-beep: the alarm clock rang. Slowly, I got out of warm bed down onto the wooden floor which the winter had thrown its cold upon. The bitter cold temperature penetrated（穿透）my socks and I hurried to put my feet in shoes.
Looking out of the window, I watched the white snow, soft and thick, drop onto rooftops and trees. Half an hour later, finishing the last of my hot chocolate, I prepared to enter the adventure that waited for me outside. I buttoned my jacket and fastened my boots. Hat on, I opened the door and was greeted by the winter coldness.
In the depths of winter, the early morning did not have the rush of the rest of the year. Most of my neighbours were put off by the cold, and stayed in bed until the sun had climbed higher into the sky.
Unseen by those who remained locked inside their homes, warm in their beds, I enjoyed being alone with the beauty of the wintertime. Those indoors were unable to appreciate the snow-scapes, ice crystals, frost and the crisp（清新的）breeze. For them, the coming of winter meant just the arrival of the cold.
Appreciation depends on contrasts. One cannot love the warmth of April if one has not known the freezing cold of winter. Later that year, the heat of the sun on my skin would be all the more wonderful for my memories of that cold morning and others like it.The underlined word “adventure” refers to____________.

One day, Wilson was walking quietly along the road when someone hit him hard on the back of his neck. He looked behind him, and saw a young man whom he had never seen before.
“How dare you hit me like that?” shouted Wilson.
The young man said he had mistaken Wilson for a friend of his and that he thought Wilson was making a lot of noise about nothing.
This insult(侮辱) made Wilson even angrier, of course, and he at once decided to bring the young man before a judge.
Now , the judge who heard the case was a friend of the young man’s father’s, and, although he pretended to be quite fair, he was thinking about what he could do to protect the young man from being punished while at the same time not to be appearing unfair.
Finally he said to Wilson, “I understand your feelings in this matter very well. Would you be satisfied if I let you hit the young man as he hit you?”
Wilson said he would not be. The young man had insulted him and should be properly punished.
“Well, then,” said the judge to the young man, “I order you to pay ten coins to Wilson.”
Ten coins was very little for such a crime, but the young man did not have it with him, so the judge allowed him to go and get it.
Wilson waited for him to return with the money. He waited an hour, and then two hours, while the judge took care of other business.
When it was nearly time for the court to close, Wilson chose a moment when the judge was especially busy, came up quietly and hit him hard on the back of the neck.
