We may think of all of these as our needs. Yet most of us would be far from satisfied if we had nothing more than these which are supplied for us. (78) We all enjoy extra income to spend on things like books, sports or hobbies. Sometimes we save some of this extra income to pay for future expense of this type on holidays. So we must add our wants to our basic needs. Our standard of living is the degree, to which these needs and wants are satisfied.
But as time goes on, what we think of as our basic needs changes. Twenty years ago a television would have been a luxury, and still is in many countries now. Even now we cannot say it is a need in the same sense as food, clothing and shelter. Yet if most of the people of a country have one, it comes to be accepted as a need．It is possible therefore to have food, clothing and shelter and still be poor by the standards of our own society.
What we need in life is divided into ________ according to this article.
A．the basic necessities and luxury
B．many kinds of need such as food, clothing and houses
C．four groups the basic necessities, luxury, reliable income and future expense
D．the basic necessities and reliable income
We all have to learn how to stop wasting our limited water. One of the steps we should take is to find ways of reusing it. Experiments have already been done in this field.
Today in most large cities, fresh water is used only once, then it runs into waste system. But it is possible to pipe the used water to a purifying factory. There it can be filtered and treated with chemicals so that it can be used again, just as it were fresh from a spring.
But even if every large city purified and reused its water, we still would not have enough. Then we could turn to the oceans. All we’d have to do to make use of the seawater on earth is to get rid of the salt.
This process is called desalinization, and it is already in use in many parts of the world.
The way to stop wasting our limited water is to （）.
A.do experiments with water
B.purify the used water and reuse it
C.use fresh water once again
D.make use of seawater
A.do experiments with water
B.purify the used water and reuse it
C.use fresh water once again
D.make use of seawater
Perhaps the best way to think of our present situation is to imagine a train coming into a switchyard. All of the switches are set before the train arrives, so that its path is completely determined. Some switches we can see, others we can not. There is no ambiguity if we can see the setting of a switch: we can say with confidence that some possible futures will not materialize and others will. At the unseen switches, however, there is no such certainty. We know the train will take one of the tracks leading out, but we have no idea which one. The unseen switches are the true decision points in the future, and what happens when we arrive at them determines the entire subsequent course of events.
When we think about the future of the universe, we can see our "track" many billions of years into the future, but after that there are decision points to be dealt with and possible fates to consider. The goal of science is to reduce the ambiguity at the decision points and find the true road that will be followed.
According to the passage, it is difficult to be certain about the distant future of the universe because we ______.
A．have too many conflicting theories
B．do not have enough funding to continue our research
C．are not sure how the universe is put together
D．have focused on investigations of the moon and planets

However, the 【72】 of energy which we use is 【73】 every year, and we only have enough coal, gas, and oil for the next twenty or thirty years. How will we live 【74】 the energy which these things give us？ Scientists are looking for 【75】 to this problem. They are looking for new 【76】 to produce energy. For example, they are working with new ways 【77】 energy from the light and heat of the sun. They are also working with plans which produce energy from 【78】 of the oceans. All of the new methods 【79】 scientists are finding are still very expensive, but perhaps they will help solve our energy problems 【80】 the future.

However there is another important part of the jobs picture that was targely ovedookcd. There was a big jump in the number of people who report voluntarily working part-time. This figure is now 830,000（4,4 percent）above its year ago level.
Before explaining the connection to the Obamacare, it is worth making an important distinction. Many people who work part-time jobs actually want full-time jobs. They take part-time work because this is all they can get. An increase in involuntary part-time work is evidence of weakness in the labor market and it means that many people will be having a very hard time making ends meet. There was an increase in involuntary part-time in June, but the general direction has been down. Involuntary part-time employment is still far higher than before the recession, but it is down by 640,000(9 percent)from its year ago level.
We know the difference between voluntary and involuntary part-time employment because people tell us. The survey used by the Labor Department asks people if they worked less than 35 hours in the reference week. If the answer is "yes."they are classified as working part-time. The survey then asks whether they worked less than 35 hours in that week because they wanted to work less than full time or because they had no choice. They are only elassified as voluntary part-time workers if they tell the survey taker they chose to work less than 35 hours a week.
The issue of voluntary part-time relates to Obamacare becanse one of the main purposes was to allow people to get insurance outside of employment. For many people, especially those with serious health conditions or family members with serious health conditions, before Obamacare the only way to get insurance was through a job that provided health insurance.
However, Obamacare has allowed more than 12 million people to either get insurance through Medicaid or the exchanges. These are people who may previously have felt the need to get a full-time job that provided insurance in order to cover themselves and their families. With Obamacare there is no longer a link between employment and insurance.
36. Which part of the jobs picture was neglected？
A.The prospect of a thriving job market.
B.The increase of voluntary part-time jobs.
C.The possibility of full employment.
D.The acceleration of job creation.
Many people work part-time because they___________________A.prefer part-time jobs to full-time jobs
B.feel that is enough to make ends meet
C.cannot get their hands on full-time jobs
D.haven' t seen the weakness of the market
The text mainly discusses___________________.A.employment in the US
B.part-timer classification
C.insurance through Medicaid
D.Obamacare's trouble
Involuntary part-time employment in the US___________________A.is harder to acquire than one year ago
B.shows a general tendency of decline
C.satisfies the real need of the jobless
D.is lower than before the recession
It can be learned that with Obamacare,___________________ . A.it is no longer easy for part-timers to get insurance
B.employment is no longer a precondition to get insurance
C.it is still challenging to get insurance for family members
D.full-time employment is still essential for insurance

Although photography (the Greek word for "writing with
light") and Filmmaking are now so much a part of our visual world
that we take them for granted, they are relative recent inventions. 【1】______
From the time of the Renaissance, many artists had used the
CAMERA OBSCURA draw forms and linear perspective accurately. 【2】______
A camera obscura was a dark room or box With light entering in a 【3】______
tiny hole, perhaps focused on by a lens. An inverted image from the 【4】______
world beyond would be thrown on the opposite wall or side, and its
outlines could be traced on paper. But it was until the first half of【5】______
the nineteenth century that several researchers working independent 【6】______
of each other found ways to capture this image permanently.
Late in the nineteenth century, sequences of still pictures began【7】______
to lead to “movies.” In the mid-twentieth century, the technology 【8】______
of capturing moving images from the world had evolved wireless 【9】______
television broadcasts. And now computer video graphics have opened
up vast new range of possibilities that may or may not originate in 【10】______
the world that we see.
