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.

People don’t take their present for the wedding. They send them to the woman’s house before the wedding day. Most weddings take place before lunch or in the early afternoon. Many people like to get married in church. The bride often wears a long white dress. Guests wear their best clothes and most of the women wear hats. In the church, the bride’s family sits on the left and the groom’s one sits on the right. Married people wear their wedding rings on the third finger of the left hand. Most married women wear wedding rings, but married men often do not.
According the passage, which of the following is NOT true?
A. Invitations are sent out some weeks before the wedding day.
B. People who accept the invitations have to send their presents to the couple.
C. It is not easy to choose a present for the couple.
D. Married people wear their wedding rings on the third finger of the right hand.

During the last 400 years, most scientists have (31)_______ on mathematics for the development of their inventions or discoveries. However, one great British scientist, Michael Faraday, did not make (32)_______ of mathematics. Faraday, the son of a poor blacksmith, was born in London in 1791 and had no education beyond reading and writing.
In 1812, Faraday was hired as a bottle washer by the great chemist Humphrey Davy. Later, Faraday became a greater scientist than Davy, making the last years of Davy’s life embittered (33)________ jealousy. Faraday made the first electric motor in 1821, a device that used electricity to produce movement. Then Faraday became interested in the relationship between electricity and magnetism. In 1831, he (34)_________ that when a magnet is moved near a wire, electricity flows in the wire. With this discovery, he produced a machine for making electricity called dynamo. Faraday then went on to show how electricity affects chemical substances.
Because Faraday believed that money should be given to the poor, when he grew old, he was very poor. However , Queen Victoria (35)________ him for his discoveries by giving him a stipend and a house. He died in 1867.
