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

X Read the passage. Answer the questions below.

Scientists have discovered that the ozone layer is getting thinner. Some predict that the sun’s rays will cause a sharp increase in deaths from skin cancer over the next fifty years. These harmful rays can also damage the eyes, create wrinkles, and cause other health problems.

​The stratosphere contains a form of oxygen called ozone. Ozone is a molecule composed of three oxygen atoms. The chemical formula of ozone is 03. Oxygen molecules make up about 21% of all gases in the Earth’s atmosphere. They consist of two atoms of oxygen and are labeled 02. Most ozone found in our atmosphere is formed by an interaction between oxygen molecules and ultraviolet radiation (UV) from the sun. When ultraviolet radiation hits an oxygen molecule, it may cause the molecule to break apart into single atoms of oxygen. These single atoms are very reactive, and a single oxygen atom can combine with a molecule of oxygen to form ozone.

​1.​What do people say about the rate of deaths from skin cancer in the future?​

​2. ​How many oxygen atoms are there in a molecule?​

​3.​What elements participate in the formation process of ozone?​

​4.​What happens when an oxygen molecule and an ultraviolet radiation hit each other?

III. Read the following passage carefully and choose the best answer to each question. Identify your answer by writing the corresponding letter A, B, C or D on your answer sheet.

One of the most urgent environmental problems in the world today is the shortage of clean water. Having clean drinking water is basic human right. But acid rain, industrial pollution and garbage have made many sources of water undrinkable. Lakes, reservoirs and even entire seas have become vast pools of poison. Lake Baikal in Russia is one of the largest lakes in the world. It contains a rich variety of animals and plants, including 1,300 rare species that do not exist anywhere else in the world. But they are being destroyed by the massive volumes of industrial effluent which pours into the lake everyday. Even where law existed, the government did not have the power to enforce them. Most industries simply ignore the regulations. The Mediterranean Sea occupies 1% of the world’s water surface. But it is the dumping ground for 50% of all marine pollution. Almost 16 countries regularly throw industrial wastes a few miles off shore.

Water is free to everyone. A few years ago people thought that the supply of clean water in the world was limitless. Today, many water supplies have been ruined by pollution and sewage. Clean water is now scarce, and we are at last beginning to respect this precious source. We should do something now.

Formed in the sea of the Philippines, Linda strengthened as it moved westward. Later, it struck extreme Southern Vietnam with winds of 100 kilometres an hour. Over 3000 people were reported lost and died. Ca Mau province, suffered a direct hit by the storm, had the most damage. Gusts and heavy rainfalls caused flooding, destroyed crops, damaged about 200,000 houses and left about 383,000 people homeless. Linda later struck Thailand, causing flash flooding and at least 164 deaths. The storm also affected Myanmar, Indonesia, Malaysia, and Cambodia to a lesser degree.

Today, residents in Mekong Delta still remember Linda after 20 years. The duration of the time is enough for a kid to grow up from an unforgettable event. The memory of a particular typhoon improves everyone’s awareness of natural disasters.

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?

1.     What does the passage mainly discuss?

        A. Days on Mercury                                    B. What Mercury is like

        C. the hottest planet                                    D. has many moons

3.     The word "It" in paragraph 2 refers to _____________.

        A. Earth                    B. Mercury                C. Venus                   D. Mars

4.     The word "spins" in paragraph 3 can be best replaced by _____________.

        A. comes                   B. arrives                   C. appears                 D. moves

5.     It can be inferred from the passage that a year on Mercury _____________.

        A. has 59 days                                            B. much longer than that on Earth

        C. has 88 days                                             D. has only 180 days
