Space is where our future is — trips to the Moon, Mars and beyond. Most people would think that aside from comets(彗星) and stars, there is little else out there. But, since our space journey started we have left so much trash(垃圾) there that scientists are now concerned that if we don’t clean it up, we may all be in mortal(致命的) danger.
The first piece of space junk was created in 1964, when the American satellite Vanguard Ⅰ stopped operating and lost its connection with the ground center. However, since it kept orbiting around the Earth without any consequences, scientists became increasingly comfortable abandoning(抛弃) things that no longer served any useful purpose in space.
It is estimated(估计) that there are now over 500,000 pieces of man-made trash orbiting the Earth at speeds of up to 17,500 miles per hour. The junk varies from tiny pieces of paint chipped off rockets to cameras, huge fuel tanks, and even odd items like the million-dollar tool kit that astronaut Heidemarie Stefanyshyn Piper lost during a spacewalk.
The major problem with the space trash is that it may hit working satellites and damage traveling spacecraft(飞船). Moreover, pieces of junk may collide(碰撞) with each other and break into pieces which fall back to the Earth. To avoid this, scientists have invented several ways for clearing the sky. Ground stations have been built to monitor larger pieces of space trash to prevent them from crashing into working satellites or space shuttles. Future plans include a cooperative effort among many nations to stop littering in space and to clean up the trash already there.
1.What was the first piece of man-made space trash?
A. A camera. B. A tool kit.
C. A broken satellite. D. A fuel tank.
2.Why were scientists NOT concerned about space trash in the beginning?
A. It did not cause any problems.
B. It no longer served any useful purpose.
C. It was millions of miles away from the Earth.
D. It was regarded as similar to comets and stars.
3.Which of the following statements is true about space junk?
A. It is huge, heavy machines.
B. It may cause problems for space shuttles.
C. It floats slowly around the Earth.
D. It never changes position.
4.What has been done about the space trash problem?
A. Ground stations are built to help store the trash properly in space.
B. Many nations have worked together to stop polluting space.
C. Large pieces of space trash are being closely watched.
D. Scientists have cleaned up most of the trash.

The US space agency NASA is looking for people to go to Mars, and stay there. This attractive career is for people who want a huge change of scenery and planet. The project is called the Hundred Years Starship, which aims to colonize (开拓殖民地) other lands such as the red planet Mars.
Settlers would travel to the red planet and live there forever. NASA says it would be too expensive to bring humans back to Earth. The space agency can afford, however, to send supplies to the astronaut pioneers from Earth. Astronauts would be landed on the planet's surface and would never be able to return home due to the cost.
NASA has started the project with $1.6 million, and hopes to attract investment from space-living billionaires. Google co-founder Larry Page told NASA he would be interested if the cost of a one-way ticket can go down from $10 billion to $2 billion.
The journey to Mars could take 4 months. Setting on the red planet would be extremely dangerous, especially given the freezing temperatures there. The thin atmosphere would be another problem as it is mostly carbon dioxide, so oxygen supplies are a must. A director in NASA said that he believed the trip might start with visiting Mars's moons first. He claimed that humans could be on Mars's moons by 2030.
Many scientists think colonizing space is absolutely necessary. Steven Hawking believes we must move to other planets to survive as a species. He said: “Once we spread out into space and establish independent colonies, our future should be safe.” Scientists Dirk' Schulze-Makuch and Paul Davies also call it a “desirable goal”, though there surely are huge risks to explore new lands.
1.Which of the following is TRUE about the Hundred Years Starship?
A．It has cost NASA around $10 billion.
B．It is expected to be conducted on Mars in 2030.
C．It aims to explore new lands in the universe.
D．It is a project first raise by Steven Hawking.
2.We can infer from the passage that Google co-founder Larry Page _______.
A．used to be an astronaut B．is no longer rich now
C．is a fan of space travel D．is a generous man
3.What would be the best title for the passage?
A．One-way trip to Mars
B．Mars's another moon is found.
C．Human landing on Mars.
D．NASA's first cooperation with Google.

If a trip to Rome or Paris is in your future, be prepared: The European Union Parliament is calling for an end to visa-free travel Americans. EU lawmakers passed a resolution urging the EU Commission to impose visas on U. S. citizens traveling into the 28-nation bloc.
The dispute(争论)centers on reciprocal treatment of travelers from EU nations and the United States. While Americans have been able to travel throughout EU member nations without a visa, the U. S. still requires citizens of five EU countries-Bulgaria, Croatia, Cyprus, Poland and Romania-to apply for entry visas when visiting the U. S, Reuters reports. Citizens of the other 23 EU member nations can use the U. S. visa waiver program to enter America. The EU lawmakers are calling for mutual treatment for all EU citizens, says Reuters. They’ve given the EU Commission two months to respond.
The trans-Atlantic visa dispute first came to light in April 2014, according to an EU Parliament news release. At that time, five countries-Australia, Brunei, Canada, Japan and the U. S. –required visas for some EU citizens. Since then, Australia, Brunei and Japan have lifted their visa requirements for all EU citizens. Canada, which currently imposes(推行)visa requirements on Bulgarian and Romanian citizens, plans to follow suit in next December, leaving just the United States at odds with the issue of reciprocity of visa-free travel with the EU.
The EU says if a visa requirement for Americans is introduced, it would be temporary, according to a story in Money, which did not give a time frame.
1.Which of the following can replace the underlined word “reciprocal” in Paragraph 2?
A. cruel B. equal
C. unfair D. different
2.Which countries have removed visa requirements for all EU citizens according to the text?
A. Australia, Brunei and Japan
B. Australia, Brunei, Canada, Japan
C. Brunei, Canada, Japan and America
D. Australia, Brunei, Canada, Japan and America
3.What may be the best title for the text?
A. Americans may soon need a visa for traveling to Europe
B. Americans are limiting the EU citizens to enter America
C. The EU citizens can go to America for traveling without visas
D. The EU government asks for visa requirement from Americans
高二英语阅读理解中等难度题查看答案及解析
It is true that world population is growing, but this is not the cause of our current and future global problems. Believing this will cause us to ignore the real problem and risk long-term damage to our planet.
Let me start by explaining why overpopulation is a myth. For one thing, the UN Population Division regularly predicts population growth but provides a low variant (变量), medium variant, and high variant to factor in various possibilities. In the 2010 revision, their high variant suggests that the world population will be almost 16 billion in 2100, but the low variant predicts it will peak at 8 billion and decrease to just over 6 billion by 2100. In most cases, it is the low variant that has come true in the past, suggesting the same will be true of their future population predictions. In addition to this, the size of families is actually decreasing.
For another, if the Earth is overpopulated, there needs to be insufficient (短缺) food, water, and space for humans to live. However, Indian economist Raj Krishna estimates that India alone is able to increase crop produce to the point of providing the entire world’s food supply. The World Food Programme confirms that there is sufficient food grown to feed the world and there is the same amount of fresh water on the planet now as there was 10,000 years ago. So how is it possible that the number of people in the world is affecting our planet?
Therefore, it is not an increase in population but an increase in consumption that is a severe threat. Materialism and overconsumption are facts of life for everybody in the western world, as possessions reflect a person’s status in society and people strive to obtain happiness through owning the latest fashionable goods. Not only that, but waste is a common occurrence which has a huge effect on our resources. It is a sad truth that 80% of the world’s resources are currently used by just 20% of the world’s population.
Our overconsumption must be addressed now to make our lives more sustainable (可持续的) and avoid continuing the terrible damage to the environment we are causing. The key is education. If we do not work towards this but instead focus on the wrong issue, we may find ourselves living on a planet that can no longer sustain human life.
1.According to the author, what causes our current and future global problems?
A. The increase in population.
B. Shortage of food and water.
C. The fast growth of material needs.
D. Failure to protect the environment.
2.The underlined word “myth” in Paragraph 2 is closest in meaning to _________.
A. fact B. misunderstanding C. possibility D. uncertainty
3.The author stresses that _____.
A. people should save food and water
B. economists are making wrong predictions
C. wrong judgment leads to serious consequences
D. measures should be taken to reduce population
4.What is mainly discussed in the passage?
A. The real cause of global problems.
B. The severe effect of overpopulation.
C. Reasonable use of natural resources.
D. Methods to reduce overconsumption.

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 when combined with 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 sill, 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.
