IV. Read the following text and answer the questions by choosing the option A, B, C or D.

        Mercury is the smallest planet in our solar system. It's just a little bigger than Earth's moon. It is the closest planet to the sun, but it's actually not the hottest. Venus is hotter.

        Along with Venus, Earth, and Mars, Mercury is one of the rocky planets. It has a solid surface that is covered with craters. It has a thin atmosphere, and it doesn't have any moons. Mercury likes to keep things simple.

        This small planet spins around slowly compared to Earth, so one day lasts a long time. Mercury takes 59 Earth days to make one full rotation. A year on Mercury goes by fast. Because it's the closest planet to the sun, it doesn't take very long to go all the way around. It completes one revolution around the sun in just 88 Earth days. If you lived on Mercury, you'd have a birthday every three month!

        A day on Mercury is not like a day here on Earth. For us, the sun rises and sets each and every day. Because Mercury has a slow spin and short year, it takes a long time for the sun to rise and set there. Mercury only has one sunrise every 180 Earth days! Isn't that weird?

Read the text and answer the following questions by choosing the best option A, B, C, or D.

                                       How Do You Celebrate?

New Year’s Day

       New Year is one of the most popular festivals in the world, even though it is celebrated at different times and in different ways. In many western countries, people get together with family and friends on December 31st to eat, drink, and dance as they wait for January 1st. Some of the biggest parties are held on New Year’s Eve. In many countries, crowds gather in the centre of town to welcome the new year at midnight with fireworks.

      For many Asian countries like China, Taiwan, and Vietnam, the New Year is based on lunar calendar. The date changes year to year, but usually falls between January 21st to February 21st. It is traditionally seen as a time for family reunions, with people travelling across the country and from overseas. Many people wear red clothes, as it is thought to be a lucky colour. They also give “lucky money” in red envelopes to friends and family, and set off firecrackers to scare away bad luck.

      What's common among these celebrations is the meaning of the new year; it is a time to say goodbye to the past and to think about new beginnings. For example, in Japan, people organize bonenkai parties ("year forgetting parties"), which are dedicated to leaving the old year's worries and troubles behind. In many countries, people make New Year's resolutions - promises to themselves to make changes in their lives over the coming year, such as to lose weight, stop smoking, or learn a new skill.

Carnival

In late February or early March, some countries celebrate a special festival called Carnival. Carnival is thought to have originated in Italy or Greece, and was held just before Lent, the 40-day period before Easter. People dressed in costumes, wore colourful masks, ate, drank, and danced all night. This tradition spread to France, Spain, Portugal, and later to Brazil and the United States.

       Now, two of the biggest Carnival celebrations take place in Rio de Janeiro in Brazil, and New Orleans in the United States. There are grand parades where people wear flashy costumes and dance and sing in the streets. In New Orleans, Carnival is known as Mardi Gras. Many roads and shops are shut down for the celebrations which can last for up to three weeks. Millions of visitors travel from around the world to join the party, and many more watch the event on television.

3. The phrase "bad luck" in paragraph 2 is closest in meaning to _____.

A. big hit       B. misfortune          C. godsend             D. triumph

As viewed from space, Earth’s distinguishing characteristics are its blue waters and white clouds. Enveloped by an ocean of air consisting of 78% nitrogen and 21% oxygen, the planet is the only one in our solar system known to harbor life. Circling the Sun at an average distance of 149 million kilometers (93 million miles), Earth is the third planet from the Sun and the fifth largest planet in the solar system.

Our planet’s rapid spin and molten nickel-iron core give rise to an extensive magnetic field which, coupled the atmosphere, shields us from nearly all of the harmful radiation coming from the Sun and other stars. Earth’s atmosphere protects us from meteors as well, most of which burn up in the Earth’s atmosphere before they can strike the surface. The planet active geological processes have left no evidence of the ancient pelting it almost certainly received soon after it formed about 4.6 billion years ago. The Earth has a single natural satellite – the moon.

Question. The word distinguishing as it is used in this selection means ________.

A. elevating in nature

B. characteristics like all other planets

Cdevastating in nature

D. characteristics that set it apart from other planets

   Our planet’s rapid spin and molten nickel-iron core give rise to an extensive magnetic field which, coupled the atmosphere, shields us from nearly all of the harmful radiation coming from the Sun and other stars. Earth’s atmosphere protects us from meteors as well, most of which burn up in the Earth’s atmosphere before they can strike the surface. The planet active geological processes have left no evidence of the ancient pelting it almost certainly received soon after it formed about 4.6 billion years ago.
