It is believed that it took about 800 thousand to 1 million years for the earth's population to reach the 250 million total which existed at the end of the first century AD. For some time after that, disease, famine and war kept the population increase down to a rate of 1 percent a year so that more than 15 centuries passed before the population reached 500 million. But in the next 250 years, up to 1850, the population of the world shot to 1 billion and today it has reached 3.5 billion. Scientists say that in the next 35 years the population of the world will double, reaching almost 7 billion by the year 2010. When experts are asked what are the most effective measures that can stop over population, they reply that at least three measures can be considered. (A) Increasing sources and supply of food for under-developed countries. (B) Increasing the industrialization of under- developed countries. (C) Controlling birth. The experts add, however, that none of the above measures can be effective by itself, and that all must be combined into one whole program. They also agree that without controlling of births, any other measures are doomed to failure. The passage was written in _ . A) 1850 B) 1936 C) 2001 D) 1975

It is probably the strangest sport anyone has ever invented.And at first sight,it looks like the easiest.Competitors have to do two things.The first is to stand still.The second is to place their hands anywhere on the body of a car,and keep it there. This is where things start getting difficult.Lots of people are doing the same thing.And the winner of the "handathon" contest is the person who can carry on doing it for the longest time.That person gets to own the car. It still seems to be an easy thing to do.At the beginning it is.Anyone can stand still.But when the contest has been going for four or five days,standing still seems like the most difficult job in the world.And keeping the hand in place over this time becomes an act of serious attention.After a few days,the hand seems to belong to someone else--someone who wants to go home and get some sleep. Competitors are allowed to take a five-minute break every hour to eat,drink or do whatever else is necessary.No one is allowed to lean on the car for support.Winners need to be able to show great powers of attention.They also need to be able to develop special skills. Maybe the popularity of the handathon is due to the fact that it is not necessary to be a trained athlete to enter.Entrants in the Longview handathon certainly don't seem to do much preparation.Most say they will prepare by "getting lots of sleep".Others say they will "eat healthy food" or "pray for success".The whole event gives ordinary people the chance to do something interesting and win something in the end. Handathons are competitions,but there is little rivalry between competitors.They help each other out and keep each other's spirits up.People who drop out early return with food,drink and encouragement. What is the writer's opinion about handathon? A) It is not as easy as it looks at first. B) It is the easiest of all sports. C) It can purify people's spirits. D) It is not good competing in a handathon.

Q: There are two types of people in the world. Although they have an equal degree of health and wealth and other comforts of life, one becomes happy, while the other becomes unhappy. This arises from the different ways in which they consider things, persons and events and the resulting effects upon their minds. People who are happy fix their attention on the convenience of things. They enjoy all cheerful things. Those who are unhappy think and speak only of unpleasant things. Through their remarks, they _ , offend many people, and make themselves disagreeable everywhere. If this turn of mind is founded in nature, such unhappy people should be pitied. The intention of criticizing and being disliked is perhaps taken up by imitation . It grows into a habit, unknown to its possessors. The habit may be strong, but it can be cured when those who have it realize its bad effects. Although this attitude is mainly an act of the imagination, it has serious results since it brings on deep sorrow and bad luck. If such people aim at getting some advantages in social position or fortune, nobody wishes them success. Nor will anyone speak a word in favor of their hopes. If they are criticized, no one will defend or excuse them, and many will join in criticizing their wrong doings. So they should change this bad habit and stop worrying needlessly about themselves and others. If they do not, it will be good for others to avoid any contact with them. Otherwise, they will have a disagreeable time, especially when someone becomes mixed up in their quarrels. The phrase "sour the pleasure of society" probably means " _ ". A) have a good attitude towards social life B) make others unhappy C) tend to scold others openly D) enjoy the pleasure of life
A: B

Producing money requires both artistic and technological skills. Dollar bills are made so that they are interesting to look at but very hard to copy. In total, there are sixty-five separate steps required to make a dollar bill. The money making process begins when. a yearly order is sent by the Federal Reserve Board. That order will then be divided in half. Half will be done here in Washington, D. C.and the other half will be done in Fort Worth, Texas. Next, the Bureau orders special paper which is actually cloth since it is 75% cotton and 25% linen. This paper is made so that it can last a long time. And, it is made with details that make it hard to copy. For example, bills contain security threads. These narrow pieces of plastic are inside the paper and run along the width of the bill. This special paper is also made with very small blue and red fibers. Once the money is printed, guillotine cutters separate the sheets into two notes, then into individual notes. The notes are organized in "bricks," each of which contains forty one-hundred-note packages. The bricks then go to one of twelve Federal Reserve Districts, which then give the money to local banks. Ninety-five percent of the bills printed each year are used to replace money that is in circulation, or that has already been removed from circulation. You may know that America's first president, George Washington, is pictured on the one- dollar bill. But do you know whose face is on the two, five, ten, twenty, fifty and one hundred-dollar bills? They are, in order. President Thomas Jefferson, President Abraham Lincoln, Treasury Secretary Alexander Hamilton, President Andrew Jackson, President Ulysses Grant and statesman Benjamin Franklin. The average life span of a one-dollar bill is twenty-one months. But a ten-dollar bill lasts only about eighteen months. The one hundred-dollar bill lasts the longest, eighty-nine months. One popular question is about the two-dollar bill. This bill is not printed very often. This is because many Americans believe... During money production, we must consider all EXCEPT that it must _ .
