Virtually any night of the year, a person can look up at the sky and see the moon. The moon is Earth’s only natural satellite. It takes slightly more than twenty-seven days for it to orbit Earth. And it does so from a little more than 380,000 kilometers away. Despite being Earth’s closest celestial neighbor, there is much about the moon that scientists do not know.
   For instance, no one is exactly sure when the moon was formed. Earth is (estimated) to have been created around 4.5 billion years ago. No later than 100,000 years after that, the moon was in orbit around Earth. Yet the remains: How did the moon form? There are several theories, but astronomers have thus far failed to prove any of them correct. The most widely accepted idea is the collision theory. It states that the moon formed when an object (crashed into) Earth. According to this hypothesis, when Earth was first created, it had no satellite. But, at some point in time, an object approximately the size of Mars collided with Earth. This caused part of the planet to break off. The largest part eventually transformed into the moon. Another theory is that Earth and the moon formed at the exact same time billions of years ago. However, many astronomers discount this theory. They point out that Earth and the moon are comprised of different substances. They claim that if the two bodies were formed at the same time, then they should be composed of the same materials. Yet, as an example of their differences, the moon has less iron than Earth does. A third theory proposes that the moon formed somewhere else in the solar system. As it wandered past Earth, it was captured by Earth’s gravity and began to orbit the planet. A fourth theory declares that, when (it) first formed, Earth spun much more rapidly than it does at the present time. Due to its swift rotation, part of the crust was stripped away from the planet and cast into space. This material then formed the moon. 

   Each of the theories has its supporters and detractors. Thus far, however, no astronomer has been able to prove one theory while disapproving all of the others.

36.What would be the best title for the passage?
A. How Long Ago Did the Moon Form?
B. Theories on the Creation of the Moon
C. The Moon: Everything You Need to Know about It
D. The Changing Phases of the Moon
37.Which of the following statements does paragraph 1 support?
A. The moon is always visible in the night sky.
B. The moon spends no more than twenty-seven days orbiting Earth.
C. The moon’s distance from Earth changes at times.
D. No natural objects are closer to Earth than the moon.

38.The word (estimated) in the second paragraph is closest in meaning to _____.
A. presumed    B. known    C. determined    D. thought
39.The phrase (crashed into) in the second paragraph is closest in meaning to _____.
A. passed    B. hit    C. interfered with    D. affected
40.Which of the following is true regarding the collision theory?
A. It declares that Mars collided with Earth at one point.
B. It points out that Earth’s orbit changed a great deal.
C. It is believed by the greatest number of astronomers.
D. It states that Earth once had multiple satellites.
41.Why do many astronomers doubt that Earth and the moon formed at the same time?
A. Earth and the moon are formed of different materials.
B. The moon more likely came elsewhere in the solar system.
C. There is not enough iron in the Earth’s crust.
D. The chances of two objects forming close together are small.
42.The word it in the passage refers to _____.
A. a fourth theory            B. the planet’s gravity
C. Earth                          D. the Solar System

   Each of the theories has its supporters and detractors. Thus far, however, no astronomer has been able to prove one theory while disapproving all of the others.

IV. Read the following passage and then decide whether the sentences are true or false according to the passage

Our planet Earth is one of nine planets revolving around the sun, a fairly small and ordinary star, which lies in the outer areas of the Milky Way Galaxy. There are about 250 billion stars in our galaxy, and billions of galaxy in universe. People have always wondered about the possibility of intelligent life forms on other planets. In recent years, this has become serious scientific speculation. Some scientists believe that there must be large numbers of stars with planets which could support living intelligent beings. Perhaps we shall never know. The nearest star is 4.3 light years away. A light year is the distance covered by light (travelling al almost 300,000 kilometers a second), in one year. It would take the fastest Earth spacecraft about 40,000 years to reach the nearest star. For a number of years radio telescopes have been trying to pick up signals from outer space, so far without success. There are, however, millions of possible radio frequencies, and there is no reason why a completely alien civilization should not use a different type of communication, such as X-rays or even a type of wave we have not yet discovered. Suppose contacts were made with beings 300 light years away. By the lime we had sent our reply, and received their response the earth would be 600 years older. It would be an interesting, but rather slow moving conversation!

1. Nine planets but the Earth move around the sun.

2. Scientists doubt if there is intelligent life on other planets.

3. It wouldn’t be possible for the very person who sent a message to even the nearest star to receive a reply from it.

4. The universe is immense.

5. We still haven’t received any signals from outer space.

-What is the most important character trait an explorer should have?

(Đặc điểm tính cách quan trọng nhất mà một nhà thám hiểm nên có là gì?)

There are several important character traits that an explorer should have, but one of the most important is determination. Exploration can be a difficult and dangerous endeavor, and setbacks and obstacles are common. A determined explorer will be able to persevere through these challenges and continue on with their mission. Other important character traits for an explorer include courage, adaptability, resourcefulness, and an open-mindedness to different cultures and ways of life.

(Có một số đặc điểm tính cách quan trọng mà một nhà thám hiểm nên có, nhưng một trong những đặc điểm quan trọng nhất là sự quyết tâm. Khám phá có thể là một nỗ lực khó khăn và nguy hiểm, và những thất bại và trở ngại là phổ biến. Một nhà thám hiểm quyết tâm sẽ có thể kiên trì vượt qua những thử thách này và tiếp tục sứ mệnh của mình. Những đặc điểm tính cách quan trọng khác đối với một nhà thám hiểm bao gồm lòng dũng cảm, khả năng thích ứng, sự tháo vát và tư duy cởi mở đối với các nền văn hóa và lối sống khác nhau.)

- Where on Earth is the most dangerous area to explore: a desert, the polar regions, or the sea?

(Nơi nào trên Trái đất là khu vực nguy hiểm nhất để khám phá: sa mạc, vùng cực hay biển?)

A desert is considered the most dangerous area to explore on Earth due to its extreme conditions. The lack of water and shade, high temperatures during the day, and extremely low temperatures at night can cause dehydration, heatstroke, and hypothermia. Moreover, sandstorms and strong winds can make it difficult to navigate and cause visibility issues. Additionally, deserts are often remote and isolated areas, which means that getting help or rescue can be challenging. All of these factors make the desert a very challenging and dangerous place to explore.

(Sa mạc được coi là khu vực nguy hiểm nhất để khám phá trên Trái đất do điều kiện khắc nghiệt của nó. Việc thiếu nước và bóng râm, nhiệt độ cao vào ban ngày và nhiệt độ cực thấp vào ban đêm có thể gây mất nước, say nắng và hạ thân nhiệt. Ngoài ra, bão cát và gió mạnh có thể gây khó khăn cho việc điều hướng và gây ra các vấn đề về tầm nhìn. Ngoài ra, sa mạc thường là những vùng xa xôi và hẻo lánh, điều đó có nghĩa là việc nhận trợ giúp hoặc giải cứu có thể là một thách thức. Tất cả những yếu tố này làm cho sa mạc trở thành một nơi rất khó khăn và nguy hiểm để khám phá.)
