Choose the best options to answer the following questions.
It took hundreds of thousands of years for the world population to grow to 1 billion. However, in just another two centuries, it grew sevenfold. You know, in 2011, the total population of the world reached 7 billion. And today, it's about 7.5 billion. Tokyo, with 37.8 million residents, continues to be the largest city in the world in terms of population.
Advances in modern medicine are the main cause of this dramatic growth in the world population. It helps the birth rates increase and the death rates decline. The second contributor is the improvement in living standards. This leads to the rise of global lifespan, from 64.8 years in the early 1990s to 70.0 years today. Last but not least, the number of women of reproductive age is increasing day by day.
However, the rapid population growth can lead to the shortage in medical and educational facilities and services. The population grows fast so the demand for energy also increases. Therefore, energy shortages are also a big problem. In addition, air, water and land pollution caused by growing population in big cities has bad effects on people's health.
How many people were there in the world in 2011?
A. 1 billion
B. 7 billion
C. 7.5 billion
D. 37.8 million
Đáp án B

Read the following passage and choose A, B, C or D to indicate the correct answer to each of the following questions.
In many ways, the increasingly rapid pace of climate change is a direct result of the growth of the human population. In the last 100 years, the world population has more than tripled, from just under 2 billion at the beginning of the century to nearly 7 billion today. In addition, the average person uses more energy and natural resources than the average person one hundred years ago, meaning that the rates of consumption are actually much higher than just the increase in population would imply. For example, it took the world 125 years to use the first one trillion barrels of oil. The next trillion barrels will be used in less than 30 years, which is almost 5 times as fast, not three.
All of these activities: food production, energy usage, and the use of natural resources, contribute to climate change in some way. The greater amounts of oil and other fuels burned to create energy release chemicals which add to global warming. In order to produce more food, farmers cut down trees to gain more land for their fields. In addition, we cut down trees to build the houses needed for a larger population. Those trees are an essential part of controlling global warming; others are too numerous to mention.
In addition to a growing population, the world also has a population that desires a higher standard of living than in the past, and a higher standard of living requires the use of even more natural resources. A look at one country will provide a clear example of this fact. China is the world’s most populous nation, with 1.3 billion people. Currently, the standard of living for most of those people is far below that of people in first world nations. Therefore, the average Chinese citizen uses far fewer natural resources and less energy than the average citizen of the US or Japan. But China is growing in power, and more of its citizens are beginning to expect a first world lifestyle. If every Chinese person attains a first world lifestyle, the amount of energy and natural resources needed in the world will double, even if the standard of living in every other nation on Earth remains the same as it is today.
How many years did it take the world years to use the first one trillion barrels of oil?
A. 100 years
B. 125 years
C. 30 years
D. 7 years
Đáp án B
Thế giới đã sử dụng một nghìn tỷ thùng dầu đầu tiên trong bao lâu?
A. 100 năm
B. 125 năm
C. 30 năm
D. 7 năm
n Janqry I9,200,6,NASA* launched a new spacecraft called New Horizons into outer space. New Horizons is expected to travel about 3 billion miles for 10 years at around 50,000 kilometers per hour and take pictures of Pluto (the last planet in the solar system*),its moons, and the Kuiper KY-pun) Belt. It will also analyze Pluto's atmosphere and temperature. Scientists say that now is our last chance to send a spacecraft to Pluto. Otherwise Pluto will become too far from Earth and it will be more difficult to get near the planet. The New Horizons mission is important because no spacecraft has ever been sent that far before. The information collected during this mission will help to explain what the outer edges of the solar system look like and how the solar system was formed 4.5 billion years ago. * NASA: National Aeronautics and Space Administration * the Solar System: the Sun, Mercury, Venus, Earth, Mars, Jupiter, Saturn, IJranus, Neptune, Pluto

Read the following passage on transport, and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 43 to 50.
The Sun today is a yellow dwarf star. It is fueled by thermonuclear reactions near its center that convert hydrogen to helium. The Sun has existed in its present state for about four billion six hundred million years and is thousands of times larger than the Earth.
By studying other stars, astronomers can predict what the rest of the Sun’s life will be like. About five billion years from now, the core of the Sun will shrink and become hotter. The surface temperature will fall. The higher temperature of the center will increase the rate of thermonuclear reactions. The outer regions of the Sun will expand approximately 35 million miles, about the distance to Mercury, which is the closest planet to the Sun. The Sun will then be a red giant star. Temperatures on the Earth will become too high for life to exist.
Once the Sun has used up its thermonuclear energy as a red giant, it will begin to shrink. After it shrinks to the size of the Earth, it will become a white dwarf star. The Sun may throw off huge amounts of gases in violent eruptions called nova explosions as it changes from a red giant to a white dwarf.
After billions of years as a white dwarf, the Sun will have used up all its fuel and will have lost its heat. Such a star is called a black dwarf. After the Sun has become a black dwarf, the Earth will be dark and cold. If any atmosphere remains there, it will have frozen over the Earth’s surface.
It can be inferred from the passage that the Sun ___.
A. has been in existence for 10 billion years
B. is approximately halfway through its life as a yellow dwarf
C. will continue to be a yellow dwarf for another 10 billion years
D. is rapidly changing in size and brightness
Đáp án B
