An Event of Imagination
The year is 2094. It has been announced that a comet is heading towards the Earth. Most of it will
miss our planet, but two pieces will probably hit the southern half of the Earth.
On 17 July, a piece four kilometers wide enters the Earth's atmosphere with a massive explosion.
About half of the piece is destroyed, but the remaining part hits the South Atlantic at 200 times the speed of sound. The sea boils and a huge hole is made in the seabed. Huge waves are created and spread outwards from the hole. The wall of water, a kilometer high, rushes towards southern Africa at 800 kilometers an hour. Cities on the African coast are totally destroyed and millions of people are drowned.
Before the waves reach South America, the second piece of the comet lands in Argentina.
Earthquakes and volcanoes are set off in the Andes Mountains. The shock waves move north into California and all around the Pacific Ocean. The cities of Los Angeles, San Francisco and Tokyo are completely destroyed by earthquakes. Millions of people in the southern half of the earth are already dead, but the north won't escape for long. Because of the explosions, the sun is hidden by clouds of dust, and temperature around the world falls to almost zero. Crops are ruined. The sun won't be seen again for many years. Wars break out as countries fight for food. A year later, no more than 10 million remain alive.
Could it really happen? In fact, it has already happened more than once in the history of the Earth. The
dinosaurs (恐龙) were on the Earth for over 160 million years. Then 65 million years ago they suddenly disappeared. Many scientists believe that the Earth was hit by a piece of object in space. The dinosaurs couldn't live through the cold climate that followed and they died out. Will we meet the same end?

Education has an important effect on the mind or physical ability of an individual. It is the process by which society passes its accumulated knowledge, skills, and values from one generation to another.

Various non- traditional education options are now available and continue to flourish（繁荣）. One of the most important uses in education is the use of technology. Teachers are encouraged to use new technological devices in order to strengthen learning among students and meet the needs of various types of learners.

The right to education has been created and recognized by jurisdiction（司法）. Education is the most important concern of the government of India. Recently India has gained world recognition because many students from foreign countries come here to gain higher qualifications. One has to be educated in order to speed up the growth process in order to influence the economy. Education is indeed a powerful weapon to stop the cut- throat competition that man faces at every period of life. The importance of education in India is progressing with time. Although India has been a great foundation of learning for many years, it still needs to improve not just on the quality of education but also on the number of people being educated.

Education is not just for academic success but also to make a person become a better human being and a better performer in life. Education makes the students able enough, so that they can compete nationally and internationally. To make a student a successful survivor in life, the responsibility lies equally with the schools and the parents too. Selecting a good school is as important as choosing a suitable career option for a child. The goal of education is the advancement of knowledge and the dissemination of truth. It is education that gives us all the power and necessities of making a difference in any field.

People who are not educated have few opportunities to do what they want to do. Educated people become more responsible and informed citizens, and have a voice in politics and society. It allows people to be more productive by encouraging them to play responsible roles in terms of contributing to society.

The right pair of exercise shoes can do a lot to prevent discomfort and injuries, personal trainers say. Here are some shopping tips:

?　 71　 Depending on your workout, shoes designed for walking, running, tennis, cross-training or another specialty will provide the best support for your feet.

Shop when you normally exercise. Feet actually get bigger throughout the day, sometimes swelling up as much as a half-size by nighttime.　 72　

Try them on. Never grab a pair of exercise shoes based only on the size of footwear you normally buy. Bring the type of socks you’d wear to work out and go for a walk through the store.

　 73　 You should be able to spread your toes out comfortably. Make sure there’s about a half-inch of space between them and the front of the shoe. The back should fit snugly (warmly and comfortably) against your heel and not move up and down. If your feet are different sizes, buy based on the larger one.

Talk to an expert. Shoe salesmen and personal trainers can study your stride (步伐) and the shape of your feet.　 74　

　 75　 Many trainers recommend switching footwear every three to five months, if possible, to maintain proper cushioning and support.

One tip: if you have to tie your shoes very tightly to feel a good amount of support, they may be ready to go.

A. Think about how much you can afford to buy the workout shoes.

B. Consider your type of exercise.

C. Focus on fit.

D. So don’t shop first thing in the morning if you often work out in the evening.

E. Pay more attention to new style shoes.

F. Replace worn shoes regularly.

G. Usually they can recommend the best shoes to guard against injuries.

Recently the World Health Organization announced that the disease of smallpox（天花）had almost been wiped out in most parts of the world, thanks to widespread vaccination（种牛痘）. Most people are vaccinated at least once in their lives and if they wish to travel from one country to another they must be able to prove that they have had a recent vaccination. In this way the disease has been prevented from spreading and today one seldom hears of it at all.
This is mainly because of the great discovery made by a village doctor, Edward Jenner, in about 1798 when he published his report of his new experiment called vaccination (from the word ‘vacca’ meaning a cow). Jenner discovered that people who worked with cattle often suffered from a harmless disease which they caught from the cattle, but these people never seemed to get smallpox. So he experimented by putting the disease into a small opening on the arms of healthy people, and though their arms became painful for a day or two, they soon recovered and none of these people ever got smallpox.
So the news of the wonderful discovery spread to other countries and people
rushed to their doctors to be vaccinated. In many countries the simple way to deal with the arm was done on thousands of people, and the terrible smallpox began to disappear.
71．Vaccination against smallpox has been so successful that _________ .
A．the discoverer made a large amount of money
B．Dr Jenner was given a prize by the World Health Organization
C．smallpox has almost disappeared in most countries
D．smallpox was no longer in existence on earth
72 ．Smallpox has been prevented from spreading through the following measures EXCEPT that _____.
A．most people were vaccinated against the disease at least once
B．people going abroad should promise not to spread the disease
C．people travelling from one country to another must prove they
are vaccinated
D．people must be vaccinated shortly before going to foreign countries
73 ．What led Dr Jenner to experiment with vaccination was that ________ .　
A．he wanted to make a great discovery and publish it
B．vaccination could make people's arms safe
C．he tried to cure the farmers of some disease caught from the cattle
D．those who worked with cattle seemed free from getting smallpox
74．The doctor's new discovery was called ‘vaccination’ for the reason that ________ .
A．he discovered smallpox near a farm
B．he experimented with a disease from the cattle
C．he was working with cattle in the countryside
D．people got the disease of smallpox from the cattle
75．The news of the discovery ________.
A．caught people's attention from all corners of the world
B．spread far and near in the western countries
C．made people rush to Dr Jenner for vaccination
D．helped to get rid of the terrible disease of smallpox
