Read the article and select the best answer. Article: Light travels at a speed which is about a million times faster than the speed of sound. In one second, light travels about 300,000km, but sound travels only 344m. You can get some idea of this difference by watching the start of a race. If you stand some distance away from the starter, you can see smoke come from his gun before the sound reaches your ears. This great speed of light produces some strange facts. Sunlight takes about 8 minutes to reach us. If you look at the light of the moon tonight, remember that the light rays left the moon 1.3 seconds before they reached you. The nearest star is so far away that the light which you can see from it tonight started to travel towards you four years ago at a speed of nearly 2 million km per minute. In some cases the light from one of tonight's stars started on its journey to you before you were born. Thus, if we want to be honest, we cannot say " The stars are shining tonight." We have to say, " The stars look pretty. They were shining four years ago but their light has only just reached Earth." Question: If you stand 200 meters away from a man who is firing a gun to start a race, you will find out that _ . Options: A: you can hear the gun before you see the smoke. B: sound does not travel as fast as light. C: the sound of the gun will reach you before the man fires his gun. D: sound travels about a million times faster than light.

Read the article and select the best answer. Article: Some people would say that the Englishman's home is no longer his castle; that it has become his workshop. This is partly because the average Englishman is keen on working with his own hands and partly because he feels, for one reason or another, that he must do for himself many households for which, some years ago, he would have hired professional help. The main reason for this is a financial one. The high cost of labor has meant that builders' and decorators' cost have reached a level which makes them prohibitive for house-proud English-people of modest means. So, if they wish to keep their houses looking bright and smart, they have to tackle some of the repairs and decorating themselves. As a result, there has grown up in the post-war years what is sometimes referred to as the "do-it-yourself movement". The "do-it-yourself movement" began with home decorating but has spread into a much wider field. Nowadays there seem to be very few things that can't be made by the "do-it-yourself movement" method. A number of magazines and handbooks exist to show hopeful handymen of all ages just how easy it is to build anything from a coffee table to a fifteen-foot sailing boat. All you need, it seems, is a hammer and a few nails. You follow the simple instructions step by step and, before you know where you are, the finished article stands before you, completely in every detail. Unfortunately, alas, it is not always quite as simple as it sounds! Many a budding "do-it-yourself" has found to his cost that one can not learn a skilled craftsman's job overnight. How quickly one realizes, when doing it oneself, that a job which takes a skilled man an hour or so to complete takes an amateur handyman five or six at least. And then there is the question of tools. The first thing the amateur learns is that he must have the right tools for the job. But tools cost money. _ It is not surprising then that many people have come to the conclusion that the expense of the paying professional to do the work is, in the long run, more... Question: Many Englishmen join in the movement of "do-it-yourself", because _ . Options: A: they are skilled handymen B: they are proud of their houses C: they can't afford professional help D: they are mean enough

Read the article and select the best answer. Article: Hundreds of years ago, Native-American tribes lived in Mexico. The Aztecs built beautiful cities. They had a calendar and a written language. However, the Spanish destroyed the Aztecs in l521. For the next 300 years, Spain ruled over Mexico. That's why Mexicans speak Spanish. Every September l6 the Mexican people hold a celebration in Mexico City, their country's capital. It is their Independence Day. On that date in 1821 they told Spain they would no longer be ruled. Breaking free from Spain caused a war. When it was over, the Mexicans had their own government. They made their own laws. Today America and Mexico are friends, but it wasn't always that way. President James Polk wanted America to reach from the Atlantic Ocean to the Pacific Ocean. He tried to buy what is now the American southwest from Mexico. Mexico would not sell. So from l846 to 1848 Mexico and America fought a war to ascertain where their borders would be. When the war ended, Mexico had lost a lot of land. Now the Rio Grande River forms the border between the two nations. America is on the north side of the river. Mexico is on the south side. Mexico has mountains and a hot, dry climate. Crops can grow on only a small part of the land. Still, Mexicans grow much of the coffee, oranges, and sugar used in the US. Mexicans have influenced building styles in southwestern US and added words such as patio and canton to American English. Americans also enjoy eating many Mexican foods like burritos, tacos, tortillas, and tamales. Question: Mexicans have the following influences on America EXCEPT _ . Options: A: building styles B: vocabulary C: clothes D: food
