Read the following passage and choose the correct answer to each of the following questions:
Smog is a combination of smoke and fog. It occurs when gases from burnt fuel mix with fog on the ground. When heat and sunlight get together with these gases, they form fine, dangerous particles in the air.

Smog occurs in big cities with a lot of traffic. Particularly, in the summertime, when it is very hot, smog stays near the ground. It is dangerous to our breathing, and in smoggy areas, we cannot see very well.

Smog was first discovered in Great Britain in the 19th century, during the beginning of the Industrial Revolution. At that time, people used coal for heating and cooking. Factories also used coal to produce iron and steel. Smoke mixed with wet, foggy air and turned yellow. The smog often hung over cities for many days. It caused lung diseases and breathing problem. Thousands of people died in London every year.

Today, cities that have a large population and are located in hot, subtropical areas have the biggest smog problems - for example, Los Angeles, Mexico City and Cairo. 

What probably caused the smog in Britain at the beginning of the Industrial Revolution?

Where will you go on your next vacation? Disneyland? Sea World? Outer space?

That’s right; tourists are now paying big bucks to travel into space with astronauts! The first space tourist was Dennis Tito, an American businessman. In 2001, he paid about $20 million to ride on a Russian rocket to the International Space Station. The Space Station circles 220 miles above Earth. Tito stayed on the station for a week, hanging out with astronauts and eating space food.

The latest space tourist was Anousheh Ansari, an Iranian-born woman from the United States who went to the Space Station in mid-September 2006.

How safe is space travel? Apart from the risk of crashing, space tourists have some special things to worry about. Earth’s atmosphere protects us from dangerous radiation from the sun. Space travellers are exposed to more of the sun’s rays. But for tourists spending only a few days or weeks in space, the radiation probably isn’t harmful.

A bigger problem might be space sickness. Without Earth’s gravity to hold them down, visitors to the Space Station float around inside the craft. It may look like fun on TV, but it can make first-time space travellers dizzy and sick. Luckily, the sickness usually wears off quickly. Then space tourists can enjoy their trip and the amazing view of Earth.

Why are space travelers exposed to more radiation?

Europa is the smallest of planet Jupiter’s four largest moons and the second moon out from Jupiter. Until 1979, it was just another astronomy textbook statistic. Then came the close-up images obtained by the exploratory spacecraft Voyager 2, and within days, Europa was transformed into one of the solar system’s most intriguing worlds. The biggest initial surprise was the almost total lack of detail, especially from far away. Even at close range, the only visible features are thin, kinked brown lines resembling cracks in an eggshell. And this analogy is not far off the mark.

The surface of Europa is almost pure water ice, but a nearly complete absence of craters indicates that Europa’s surface ice resembles Earth’s Antarctic ice cap. The eggshell analogy may be quite accurate since the ice could be as little as a few kilometers thick – a true shell around what is likely a subsurface liquid ocean that, in turn, encases a rocky core. The interior of Europa has been kept warm over the eons by tidal forces generated by the varying gravitational tugs of the other big moons as they wheel around Jupiter. The tides on Europa pull and relax in an endless cycle. The resulting internal heat keeps what would otherwise be ice melted almost to the surface. The crack-like marks on Europa’s icy face appear to fracture where water or slush oozes from below.

Soon after Voyager 2’s encounter with Jupiter in 1979, when the best images of Europa were obtained, researchers advanced the startling idea that Europa’s subsurface ocean might harbor life. Life processes could have begun when Jupiter was releasing a vast store of internal heat. Jupiter’s early heat was produced by the compression of the material forming the giant planet. Just as the Sun is far less radiant today than the primal Sun, so the internal heat generated by Jupiter is minor compared to its former intensity. During this warm phase, some 4.6 billion years ago, Europa’s ocean may have been liquid right to the surface, making it a crucible for life.

The word “radiant” in the last paragraph is closest in meaning to______.

I get a lot of letters at this time of the year from people complaining that they have a cold that won’t go away. There are so many different stories about how to prevent or cure a cold that it’s often difficult to know what to do. Although colds are rarely dangerous, except for people who are already weak, such as the elderly or young babies, they are always uncomfortable and usually most unpleasant. Of course, you can buy lots of medicines which will help to make your cold less unpleasant, but you must remember that nothing can cure a cold or make it go away faster. Another thing is that any medicine which is strong enough to make you feel better could be dangerous if you are already taking drugs for some other illness so always with your chemist or doctor to see whether they are all right for you. And remember they might make you sleepy – please don’t try to drive if they do! Lastly, as far as avoiding colds is concerned, whatever you may be told about magic foods or drinks, the best answer is to keep strong and healthy – you’ll have less chance of catching a cold, and if you do, it shouldn’t be so bad!

The invention of the phonograph happened quite a by accident. Thomas Edison moved to Menlo Park, New Jersey, in 1876, where he established an industrial research laboratory. There, Edison was working on a carbon telephone transmitter to improve the existing Bell telephone system.

In that laboratory a year later, Edison invented the phonograph while he was trying to improve a telegraph repeater. He attached a telephone diaphragm to the needle in the telegraph repeater; in this way, he was able to produce a recording that could be played back. After he made some improvements to the machine, he tested it. He recited ‘Marry Had a Little Lamb’ into the machine and played his voice back to a very surprised audience.

Every child in England between the age of five and fifteen must attend schools. There are three main types of educational institutions, primary (elementary) schools, secondary schools, and universities

Like most countries in the world, there are two types of schools in England, independent schools (fee-paying schools) and state schools in which students do not have to pay tuition fees. In both types, attendance is compulsory. Morning classes begin at nine o’clock and last until half past four in the afternoon. After classes, most English children often stay at school and take part in extracurricular activities like sports, singing and dancing. Schools are open five days a week. On Saturdays and Sundays there are no lessons. There are holidays at Christmas, Easter and in summer. In London as in all cities there are two grades of schools for those who will go to work at fifteen: primary schools for boys and girls between the ages of five and eleven, and secondary schools for children from eleven to fifteen.

Besides such compulsory lessons as reading, writing, the English language, English literature, English history, geography, science, and nature study, children in England can take many optional subjects like drawing, painting, singing, or woodwork to develop their aptitudes.

The writer mentions all of the following types of educational institutions EXCEPT________.
