Passage Five
Some people hate everything that is modern. They cannot imagine how anyone can really like modern music; they find it hard to accept the new fashions in clothing; they think that all modern painting is ugly; and they seldom have a good word for the new buildings that are being built everywhere in the world. Such people look for perfection in everything, and they take their standards of perfection from the past. They are usually impatient with anyone who is brave enough to experiment with new or to express himself or the age in materials original ways. It is, of course, true that many artists do not succeed in their work and instead produce works that can only be considered as failures. If the work of art is a painting, the artist's failure concerns himself alone, but if it is a building, his failure concerns others too, because it may damage the beauty of the whole place. This does sometimes happen, but it is completely untrue to say, as some people do, that modern architecture is nothing.
We can't judge every modern building by the standards of the ancient time, even though we admire the ancient buildings. Technologically, the modern buildings are more advanced. The modern architect knows he should learn from the ancient works, but with his greater resources of knowledge and materials, he will never be content to imitate the past. He is too proud to do that.
51. Some people hate everything that is modern because ______.
A. they are aged
B. they find it hard to accept modern things
C. they take their standards of perfection from the Greek
D. they look at things by the standards of the past

This typifies the way in which engineers work to help people and create a better quality of life. The fact that this country has the most efficient agricultural industry in the world is another good example. Mechanical engineers have worked with farmers and biologists to produce fertilizers, machinery and harvesting systems. This team effort has now produced crops uniformly waist high or less so that they are better suited to mechanical harvesting. Similar advances with other crops have released people from hard and boring jobs for more creative work, whilst machines harvest crops more efficiently with less waste. Providing more food for the rapidly increasing population is yet another role for the mechanical engineer.
According to the passage, when would most weight be imposed on hip-joints?
A.When one is walking.
B.When one is running.
C.When one is standing.
D.When one is lying down.

It is not only luxuries which are wrapped in this way, With so many goods now produced centrally and sold in supermarkets it is becoming increasingly difficult to buy anything from nails to potatoes that is not already done up in plastic or paper.
The wrapper itself is of no interest to the shopper, who usually throws it away immediately. Useless wrapping accounts for much o the 31 pounds in weight of rubbish put out by the average London household each week. So why is it done? Some of it, like the wrapping on meat, is necessary, but most of the rest is simply competitive selling. This is stupid. Packaging is using up scarce energy and raw materials and ruining all the time. One big firm reports that its glass, cans and paper have all gone up by 30 per cent in the last couple of months, while plastic has increased by 50 percent and all these prices are still rising. This seems as yet to have had surprisingly little effect on the packaging practice of manufacturers.
Little research is being carried out on the costs in energy and materials of other possible types of packaging. Just how practical is it, for instance, for local authorities to save waste paper and re-manufacture it as egg-boxes? Would it be cheaper to plant another forest to produce new paper?
One reason for the unorganized behavior. of everyone concerned is probably the varied nature of the packaging industry. So many people, with so many different interests of their own, are affected that it is extremely hard to reach any agreement on what should be done. Also, packagers say that preserving forests and preventing waste is not their concerns.
The shopper gets rid of the wrapper immediately because______.
A.he is careless.
B.it adds to the weight.
C.it is difficult for him to handle.
D.it has no importance for him.

A Time-Budgeting Plan
Consider some practical suggestions for the arrangement of your study schedule. In other words, you need a plan to budget your time. It will pay big dividends if you will set aside a few minutes or an hour as soon as possible after classes each day. Use this time to review the materials covered in the class periods of the day. Remember that you will forget a large portion within twenty-four hours after you hear or read it for the first time. Try to find a time at the end of your regular school day-or in the middle of it, if you have vacant period. You can review what was covered in each of the day's classes before it has had time to slip out of your mind. As a result, your memory will be stepped up greatly.
A Regular Time for Study
Set aside a regular time for your study of tomorrow's lessons. If you can possibly arrange it, it is a good policy to study at the same time each day. Doing this will help avoid :the problem of needing to study and letting the time slip by so that it doesn't get done. All of us have done this. We had the best of intentions, but we did not get started until it was too late. So have a routine of studying at a certain time each day, and never schedule anything else for that time. Then you will have the best possible chance to avoid missing your study due to poor use of time.
A Place for Study
Have one particular place where you can go to study. This does not mean, of course, that you can never, under any circumstance, study anywhere else. It does mean that when you have serious study to do, you try to go to this place to do it. Pick a place that has few distractions. It must be a place where there are no conversations, no activities of friends, or no interesting noises. There must be no reminders of things more pleasant than studying to compete for your attention. A table facing a wall with nothing but your actual work materials is best. And while your chair may have a soft cushion, it should not be so comfortable that it encourages you to relax completely. Habit Can Help You Study
Get into the habit of going to a place at a certain time to study. Then you will find that it becomes easier for you to concentrate. You lose less time in warming up to your subject. Right away you will get into the proper frame. of mind at your special study place and time. When doing this becomes a habit, you have made good progress. It has become easier to make yourself go through your study routine. In other words, going to one place at a regular time for study not only helps you to get started more easily, but also replaces willpower with the habit of studying.
Which of the following statements best covers the suggestions given for study?
A.You need a regular plan, place, and time for study.
B.You must be willing to spend time and effort studying.
C.You should pick a place where you can study and won't be distracted.
D.You need to get into the habit of study.
