To make an estimate means to guess the number of things in a group or guess a measurement of some kind. It sometimes means to make a calculation about the future which is based not on exact data(数据) but on past experience.This kind of estimate has some basis, but it generally has to be changed and corrected later.
When you estimate a number, a temperature, or a weight, you do not count things one by one or use a measuring tool.You look at a group of things without counting them and try to get a rough, general idea of their number, or you try to weigh something in your hand instead of on a balance.You feel hot and say “My temperature must be 38 degrees” or you look at a room and say that you estimate its area as 10+8 feet.
But in many situations in ordinary life we do not have time to measure things and must depend on estimates.Drivers do not have time to measure the distance between their own car and a car which is coming near.They must guess it; the guess or estimate will be based on their past experience.Experienced cooks do not trouble to measure the amount of salt they put into the soup or sugar they mix with flour.
Suppose a man comes into the house and says, “There are two inches of snow on the road.” His statement is only an estimate, but we believe it because we think that it is roughly correct.We put our boots on before we go into the snow.
For practical purposes in some situations it is safe to make an estimate, but in other situations it is obviously dangerous.If it is your job to weigh drugs or make airplanes, do not depend on guessing but use an accurate(精确的) instrument.

If you can’t catch the bad guy, it’s game over-----this is the rule of life for computer game players.But similar thoughts might be worrying US president George W.Bush as he prepares for the election year with the world’s most wanted man still out of his reach.
The hunt for Laden has been going on since the attack on New York’s World Trade Center on September 11, 2001.Progress has been slow and, with John Kerry winning the race last Tuesday to compete against Bush in November’s presidential elections, the president needs results.

The latest information suggests the election will be close, with 48 percent of Americans saying they will vote for Bush and 46 percent backing Kerry.
