A remarkable variety of insects live on this planet. More species of insects exist than all other animal species together. Insects have survived on earth for more than 300 million years，and may possess the ability to survive for millions more.
Insects can be found almost everywhere—on the highest mountains and on the bottom of rushing streams, in the cold South Pole and in bubbling hot springs. They dig through the ground, jump and sing in the trees, and run and dance in the air. They come in many different colors and various shapes. Insects are extremely useful to humans, pollinating (授粉) our crops as well as flowers in meadows, forests, deserts and other areas. But ticks and some insects, such as mosquitoes and fleas, can transmit disease.
There are many reasons why insects are so successful at surviving. Their amazing ability to adapt permits them to live in extreme ranges of temperatures and environments. The one place they have not yet been found to any major extent is in the open oceans. Insects can survive on a wide range of natural and artificial foods—paint, pepper, glue, books, grain, cotton, other insects, plants and animals. Because they are small, they can hide in tiny spaces.
A strong, hard but flexible shell covers their soft organs and is resistant to chemicals, water and physical impact. Their wings give them the option of flying away from dangerous situations or toward food or mates. Also, insects have an enormous reproductive capacity: An African ant queen can lay as many as 43,000 eggs a day.
Another reason for their success is the strategy of protective color. An insect may be right before our eyes, but nearly invisible because it is cleverly disguised like a green leaf, lump of brown soil, gray lichen (青苔), a seed or some other natural object. Some insects use bright, bold colors to send warning signals that they taste bad, sting or are poisonous. Others have wing patterns that look like the eyes of a huge predator, confusing their enemies. Some insects also imitate bitter-tasting insects; hungry enemies are fooled into avoiding them.
1.Insects protect themselves from chemicals by ______.
A.hiding in tiny spaces B.flying away when necessary
C.having a strong shell D.changing colors or shapes
2.Some insects disguise like natural objects so as to ______.
A.avoid being discovered B.frighten away their enemies
C.send warning signals D.look bitter-tasting
3.The passage is mainly about ______.
A.how insects survive in different places B.why insects can survive so successfully
C.what insects can do to the environment D.where insects can be found in quantity

Are you aware that every single person on this planet who has ever lived, lives now or will live, has a different perception of reality? The way each of us perceives the world is to some degree different than any other person's perception of reality. __①__ What is absolutely real and right for you may be an illusion, or nonexistent, or completely false for another!
It's important to know this. __②__ For example, the news media loves to create drama, and one of their favorite methods is to elicit(引起) fear: fear of other people, fear of the weather, fear of the economy, etc. The news media tells us how to perceive the world—and if a person takes the newscasters at their word, they perceive the world to be very dangerous and hostile. To that person，the mental images and emotions suggested by other people create a version of reality that is completely different from the reality perceived by someone who does not watch the news.
Things are not always what they seem. For most people, seeing is believing, which is why magicians, artists and marketers are so successful. Just like the TV news, they show you only what they want you to see and it is perceived as reality. But how would that reality change if you saw what went on behind the scenes or what was left out?
What's your story?
We all have a story. Over time, your story takes on a life of its own and you become your story. But who's the author and why did him put so much crap in there? All that unnecessary suffering, struggle, heartache, worry and pain... wouldn't it be better to live a story without all that? Who wants to live in a story with that much boredom and unfulfilled longings?
The story got its start when you were born, and was coauthored by you along with the influences in your life. __③__ Anytime you were influenced by someone or something, you unconsciously handed your pen over and said “Here, you write this about me.” So you are not even writing your OWN story! No one does—until they recognize that fact, and make a conscious decision to take control of the pen. You CAN write your story the way you want it to play out.
________________
It is helpful to understand how the brain takes reality and filters it to create your unique perception of reality. It's an automatic unconscious action that is based on：
● Physical experiences (which is why some optical illusions are extremely unsettling)
● Past conditioning (how you are programmed to see the world)
__④__ When you become aware of the fact that you are constructing your own reality, you can take charge and build one that is more pleasing. If you change your mind, your vibration and your intentions, you can change your circumstances! Instead of, “I am a victim of circumstance，” imprint in your mind, “I am the cocreator of my life”； Instead of, “I am sick and tired of...” imprint in your mind，“I am in control and enthusiastic about what I do”．
Raise your vibration by thinking, talking and acting more positively. As positiveness becomes a mental habit，that change will become your new inner reality, which will soon manifest in your outer reality.
The power of perception is immense. Choose to see more good than bad, more abundance than lack, more love than indifference and more success than struggle.
1.How does the author present his viewpoints in the first three paragraphs?
A.By answering questions. B.By giving examples.
C.By making comparisons. D.By drawing conclusions.
2.The sentence “Because if you are not aware, your perception, world view and reality are created by other people.” should be put in ________．
A.① B.② C.③ D.④
3.Which of the following subtitles can be filled in the blank?
A.Seeing is not believing
B.Live up to your expectations
C.Change your perception and create a new reality
D.Physical experiences and past conditioning really count
4.What is the tone of the passage?
A.Instructive. B.Humorous.
C.Critical. D.Ironic.

For more than twenty years scientists have been searching for signs of life on other planets. Most of these searches have been done over the radio. The hope is that someone in outer space may be trying to get in touch with us. Scientists also have sent radio and television messages on spaceships traveling through space, on the chance that someone may be receptive to such messages.
Scientists are using powerful radio telescope to listen to signals from about 1,000 stars, all within 100 light years of earth. In addition, they will scan (扫视) the entire sky to “listen” for radio messages from more distant stars. Using a computer, they will be able to monitor more than eight channels at one time. Scientists are looking for any signal that stands out from the background noise.
Of the 200 billion stars in the Milky Way galaxy, scientists find that five percent are like our sun. Perhaps half of them have a planet like earth. Such a planet would be a reasonable distance from the star for temperatures to be right for the evolution (进化) of life. Based on the inhabitable (that can be lived in) planets in our galaxy, most scientists agree that chances are likely that one or more of these planets support some life.
However, many scientists wonder whether intelligent life exists on other planets. Some believe that twenty years of searching without any intelligible messages shows that no one is out there. They say that the evolution of intelligence comparable to ours is unlikely.
Other scientists believe that our search hasn’t been long enough to rule out the possibility that intelligent life exists in our galaxy. Although our sun family in only about five billion years old, our galaxy is about 20 billions years old. In that time, some scientists think it is likely that civilizations are much more advanced than ours. Perhaps these civilizations send us no signals; perhaps we have not recognized the signals they have sent us. If we hope to find intelligent life, these scientists believe that we have to keep looking.
1.According to the passage, how many planets in our galaxy might be inhabitable?
A. 15 billion. B. 10 billion.
C. 5 billion D. 200 billion
2.The first paragraph in this passage is mainly about ________.
A. why scientists are looking for signs of life on other planets
B. how scientists are looking for signs of life on other planets
C. where scientists are looking for signs of life on other planets
D. when scientists are looking for signs of life on other planets
3.The underlined word “monitor” in the passage means “________”.
A. find B. follow
C. form D. check
4.Which of these statements is True based on the information in the passage?
A. Scientists are tying different ways to find signs of life on other planets.
B. Most scientists believe that there is intelligent life on other planets.
C. The earth is one of the oldest planets in our galaxy.
D. Scientists don’t believe that there might be life on other planets.

There are billions of people on this planet, and many of us love to eat meat. Can the demand be filled in a sustainable(可持续的) and affordable way? A bunch of businessmen are not only optimistic but are working to make this happen sooner than you may think.
The environmental effects caused by meat consumption (食用)—waste, animal treatment, health problems and even the greenhouse gas effects that are potentially caused by methane gas produced by cows—have given rise to a number of startups(新兴公司)looking to develop meats in different ways.
For example, San Francisco-based Memphis Meats is developing cell-based meats in its labs without requiring any animals. Israel’s Future Meat Technologies is doing the same by producing fat and muscle cells that are being tested by chefs in Jerusalem. All of these companies use special processes to harvest cells from animals and grow them in a lab.
But don’t worry if you’re not a meat lover. Startups such as Jet Eat, which is also based in Israel, are working on food products grown in labs that are plant-based and replicate (复制) meats using natural elements while still keeping flavor, consistency and the “overall sensory experience”, according to a report on NoCamels. Jet Eat, which was founded in early 2018, aims to 3D-print their lab-grown products by 2020.
As you can imagine, there are plenty of barriers facing the industry. Educating the public is a big one. Another controversial issue is the labeling of the products. Recently both the USDA and the Food and Drug Administration(FDA) announced that they will begin jointly controlling the new “cell-based meat” category.
Many of us have concerns about the challenges facing future generations as our global population increases and the earth’s natural resources decreases. The good news is that there are plenty of businessmen around the world—like those producing lab-grown meats—who are working to solve some of these problems and make a little money in the process. Nothing wrong with that.
1.Why do some companies begin to develop new kinds of meats?
A.To analyse the causes of air pollution.
B.To stress the importance of protecting wild animals.
C.To make people less interested in eating meat and more healthy.
D.To meet people’s demand for meat in environmentally friendly ways.
2.What’s special about the lab-grown meats of Jet Eat?
A.They cost less. B.They are plant-based.
C.They are more delicious. D.They are available on the market now.
3.Which of the following is a barrier lab-grown meat industries must deal with?
A.How to let people accept the meat. B.How to give the meat an elegant name.
C.How to produce the meat in large amounts. D.How to reduce the cost of making the meat.
4.What’s the author’s attitude towards lab-grown meats?
A.Supportive. B.Opposing. C.Ambiguous. D.Cautious.

There was great excitement on the planet of Venus 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. The satellite was directed into an area known as Manhattan. Because of excellent weather conditions and extremely strong signals, Venusian scientists were able to get valuable information about the feasibility of a manned flying saucer landing on Earth. A press conference was held at the Venus Institute of Technology. "We have come to the conclusion, based on last weeks satellite landing, "Prof. Zog said, that there is no life on Earth.”
“How do you know this? "the science reporter of the Venus Evening News asked "For one thing, Earth s surface in the area of Manhattan is composed of solid concrete and nothing can grow there. For another, the atmosphere is filled with carbon monoxide and other deadly gases and nobody could possibly breathe this air and survive. “Are there any other sources of danger that you have discovered in your studies?
“Take a look at this photo. You see this dark black cloud staying over the surface of Earth? 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.”
“Over here you will notice what seems to be a river, but the satellite findings indicate it is polluted and the water is unfit to drink.”
“Sir, what are all those tiny black spots on the photographs?
We’re not certain. They seem to be metal particles that move along certain paths. They give gases, make noise and keep crashing into each other.
“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 the Earth atmosphere, then we can live anywhere.”
1.What does the underlined word feasibility in paragraph 2 mean?
A. Possibility. B. Flexibility. C. Simplicity. D. Responsibility
2.What tone did the author use when writing the text?
A. Serious B. Aggressive C. Humorous D. Frustrating

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 20000 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 (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,” Prof. Zog said, “that there is no life on 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 made up of solid concrete 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 originally planned.”
“Are there any other dangers that you discovered in your studies?”
“Take a look at this photo. You see this dark black cloud hovering(盘旋) over the surface of Earth? We don’t know what it is made of, but it could give us a lot of trouble and we shall have further tests before we send a Venus Being there.”
“Over here you will notice what seems to be a river, but the satellite findings indicates it is polluted and the water is unfit to drink. This means we shall have to carry our own water, which will add even greater weight to the saucer.”
“If all you say is true, won’t this set back the flying saucer program several years?”
“Yes, but we shall continue as soon as the Grubstart gives us the added funds.” Prof. Zog replied.
1.During the week of great excitement the Venusian scientists succeeded in getting important information as to ____.
A. the feasibility of landing a satellite on Earth
B. the possibility of making a first-rate flying saucer
C. the feasibility of sending a Venus Being to Earth
D. the possibility of directing a flying saucer into Manhattan
2.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 in their way to the planet of Earth
B. the Earth’s atmosphere is filled with deadly gases
C. there is a low level of oxygen for Venusians
D. there is no air on the planet of Earth
3.The “dark black cloud” on the photo refers to ____.
A. the polluted air hovering over the surface of Earth
B. the mass of tiny drops of water floating above Earth
C. the mass of small things moving through the air
D. the dark clouds gathering before a storm breaks
4.The author wishes to call our attention to the fact that ____.
A. that modern man has polluted his environment to such an extend that he might destroy himself if he went on like this
B. that there is a point in spending billions to land a flying saucer on Earth
C. that pollution has become so serous 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
