189. What will man be like in the future—in 5,000 or even 50,000 years from now? We can only make a guess, of course, but we can be sure that he will be different from what he is today. For man is slowly changing all the time. Let us take an obvious example. Man, even five hundred years ago, was shorter than he is today. Now, on average, men are about three inches taller. Five hundred years is a relatively short period of time, so we may assume that man will continue to grow taller. Again, in the modern world we use our brains a great deal. Even so, we still make use of only about 20% of the brain’s capacity. As time goes on, however, we shall have to use our brains more and more—and eventually we shall need larger ones. This is likely to bring about a physical change too: the head, in particular the forehead, will grow larger. Nowadays our eyes are in constant use. In fact, we use them so much that very often they become weaker and we have to wear glasses. But over a very long period of time it is likely that man’s eyes will grow stronger. On the other hand, we tend to make less use of our arms and legs. These, as a result, are likely to grow weaker. At the same time, however, our fingers will grow more sensitive because they are used a great deal in modern life. But what about hair? This will probably disappear from the body altogether in course of time because it does not serve a useful purpose any longer. In the future, then, both sexes are likely to be bald. Perhaps all this gives the impression that future man will not be a very attractive creature to look at. This may well be true. All the same, in spite of all these changes, future man will still have a lot in common with us. He will still be a human being, with thoughts and emotions similar to our own. [共5题](1) Future man is likely to be different from us ________.(A) in quite a few ways (B) in almost every way(C) in great many ways (D) in one or two ways(2) The reason for believing that future man will be different is that man ________.(A) began to change five hundred years ago(B) never stops changing(C) never stops growing(D) has recently begun to change(3) People’s heads will eventually grow larger. This is because their brains ________.(A) will grow faster than at present(B) will need more room than at present(C) will play an important part(D) will be in constant use(4) Future man will probably ________.(A) have bigger eyes (B) get weaker eyes(C) see better (D) have to wear better glasses(5) Future man’s hair will ________.(A) grow darker (B) stop growing completely(C) fall out more often (D) get longer

Passage OneLong time ago, the ancient people could not travel to any far away places for they had no vehicle to carry them across the wide oceans, deep valleys, long rivers or high mountains.Nowadays people take advantage of steamships, trains, airplanes and modern bridges. Airplanes can carry us to the far countries in a short time; steamships can travel across the wide oceans. It is convenient to the modern people.Travelling is a good idea to us because we can get more knowledge, such as the customs, the geography of other countries. And people could travel among the different countries in the world. For it is easy to travel from the land by trains, or from the sea by ships.We learnt that the Italian who made the world large was Mr. Columbus. He was a brave man. Up to the middle of the 15th century, the people were afraid of traveling because they believed it was a dangerous thing.There is a saying in China, which is "Travelling for thousands is better than reading for ten years." It is to say that we can learn more in different places than we can learn from books.36. The people in ancient times couldn't travel too far away places because______.A. they found it no use doing soB. they liked staying at homeC. there was no modern transportationD. they were forbidden to go to other countries

Think about driving a route that’s very familiar.It could be your commute to work, a trip into town or the way home.Whichever it is, you know every twist and turn like the back of your hand.On these sorts of trips it’s easy to lose concentration on the driving and pay little attention to the passing scenery.The consequence is that you perceive that the trip has taken less time than it actually has. This is the well-travelled road effect: People tend to underestimate the time it takes to travel a familiar route. The effect is caused by the way we allocate our attention.When we travel down a well-known route, because we don’t have to concentrate much, time seems to flow more quickly.And afterwards, when we come to think back on it, we can’t remember the journey well because we didn’t pay much attention to it.So we assume it was shorter.

Text 4 Many people talked of the 288,000 new jobs the Labor Department reported for June,along with the drop in the unemployment rate to 6.1 percent,as good news.And they were right.For now it appears the economy is creating jobs at a decent pace.We still have a long way to go to get back to full employment,but at least we are now finally moving forward at a faster pace.However,there is another important part of the jobs picture that was largely overlooked.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（7.9percent）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 classified 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 because 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.
It can be learned that with Obamacare,____A.it is no longer easy for parttimers 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.fulltime employment is still essential for insurance

问答题Practice 1 No one knows what time itself is. We cannot see it. We cannot touch it. We cannot hear it. We know it only by the way we mark its passing. For all our success in measuring the tiniest parts of time, time remains one of the great mysteries of the universe. One way of thinking about time is to imagine a world without time. There could be no movement, because time and movement cannot be separated. A world without time could exist only as long as there were no changes. For time and change are linked. When something changes, you know time has passed.
