Passage 1

Human sympathy  1  whales is only natural of all the creatures in the sea.  2  are closer relatives to us than these warm-blooded mammals. And how they got into the sea is one of the most fascinating stories of  3  . Most authorities believe that 60 million years ago ancestors of modern whales were four-legged, wolf-size animals living on the sea shores,  4  an abundance of fish and shrimp tempted them to try wading.  5  ten to 15 million years, their bodies GREw, forelegs shrank into flippers used for balance and steering and hind legs disappeared. As a result of some amazing transformations, they are now helpless on land.

If stranded on a beach, they can barely breathe.

With abundant  6  of food, whales GREw into the largest creatures that lived,   7  larger than dinosaurs. A blue whale can grow to 100 feet. Its tongue is ten feet thick and heavier than an elephant.

Some arteries are big enough for a child to  8  . The half-ton heart has walls two feet thick and pumps eight tons of blood.  9  its size comes awesome strength. A blue whale swimming  10   15  knots generates 1,000 horsepower.   11  their size, these giants move at a good speed. An 18-ton whale can even  12   20  m.p.h., over short distances. A whale can  13  to 9,000 pounds of food a day. The world’s biggest creature  14  itself almost entirely on shrimp-like krill smaller than a person’s thumb.

Maternal instincts are also  15  . Because a calf is born underwater, the mother must get it to the surface before it  16  . Often another whale will help.

The mother pushes it gently  17  the baby is confident with its swimming—usually after about 30 minutes. If the calf is  18  , she may support it on her back until it gradually rots away. Like all mammals, whale babies

  19  mother’s milk. And the milk is more than 30-percent fat, over ten-percent protein, and the babies grow extremely fast. A blue whale calf lengthens  20  two inches a day and gains an average seven pounds per hour.

Passage 2

Prices determine how resources are to be used. They are also the means  1   which products and services that are  2   limited supply are rationed among buyers. The price system of the United States is a very complex network  3  of the prices of all the products bought and sold in the economy as well as those of a myriad of services,   4  labor, professional, transportation, and public-utility services. The interrelationships of all these prices  5   up the “system” of prices. The price of any particular product of service is linked to a broad, complicated system of prices in  6   everything seems to depend more or less upon everything else.

If one  7   ask a group of randomly selected individuals to define “price”, many would reply that price is an amount of money  8   by the buyer to the seller of a product or service or, in other words  9   price is the money values of a product or service  10   aGREed upon in a market transaction. This definition is, of course,   11   as far as it goes.   12  a complete understanding of a price in any particular transaction, much more than the amount of money  13  must be known. Both the buyer and the seller should be  14   with not only the money amount,  15  with the amount and quality of the product or service to be exchanged, the time and place at which the exchange will take place and payment will be  16  , the form of money to be used, the credit terms and dis-counts that apply to the transaction, guarantees  17  the product or service, delivery terms, return privileges, and other factors. In other words, both buyer and seller should be fully  18  of all the factors that  19  the to-tal “package” being exchanged for the asked-for amount of money in order that they may  20  a given price.

Passage 3

It is the firm belief of astronomers  1  there are  2  creatures on other planets. It is also their earnest wish that some day  3  may be made with such creatures  4  sending messages in the  5  of radio signals. The  6  of communicating with people on other planets may one day come true since radio telescopes  7  .

Scientific project of various kinds are now  8  to  9  signals or to receive signals from  10  planets. The question now   11  : what  12   should be sent so that it could be understood? To send a message in any language would be impractical  13  it would certainly not be  14  . It is the opinion of scientists that a signal in the form of a simple arithmetic  15  might be understood. Scientists think that pictures might also be understood, so it  16  a good idea to send pictures of the people  17  our planet. Pictures of domestic animals together with various crops we  18  for our food might also be transmitted. Pictures of houses and buildings might  19  further information about our life and society. As time goes on, TV pictures might be sent which would further acquaint the beings on other planets  20  life and the level of civilization on our planet.

Passage 5

Non-infectious diseases  1  stroke, heart attacks and cancer will become the  2  cause of death worldwide within 25 years and poorer countries are not prepared  3  the shift,   4  two international reports  5  on Sunday. These diseases are  6  leading killers in rich nations, but are  7  the rise in poorer countries as people live longer and  8  lives.

  11  2020, life expectancy at birth will be 71 years worldwide, and almost 88 years  12  women in industrialized countries.

“The findings across regions are  13  the view that we live a longer, healthier life,” said Christopher Murray, a Harvard expert  14  co-authored one of the twin reports prepared for the World Health Organization and the World Bank.

The studies  15  help national health systems and the international aid agencies prepare for changes and set priorities through to the year 2020. One recommendation is more research and development, investing in  16   vaccine  research  or  public  health,  such  as  17  programmes.

As in the industrial world, heart attacks and cancer will become major killers in the poorer nations. That is partly  18  tobacco-related health problems,  19  are growing faster than the AIDS epidemic. Murray found that smoking-related deaths could nearly triple to 8.4 million a year worldwide.

Passage 6

Until recently most historians spoke very critically of the Industrial Revolution. They  1  that in the long run industrialization GREatly raised the standard of living for the  2  man. But they insisted that its  3  results during the period from 1750 to 1850 were widespread poverty and misery for the  4  of the English population.   5   contrast, they saw in the preceding hundred years from 1650 to 1750, when England was still a  6  agricultural country, a period of great abundance and prosperity.

This view,  7  , is generally thought to be wrong. Specialists  8  history and economics, have  9  two things: that the period from 1650 to 1750 was   10   by GREat poverty, and that industrialization certainly did not worsen and may have actually improved the conditions for majority of the populace.
