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
Theo thông tin bài văn cung cấp, ta thấy:
- “The Sun has existed in its present state for about four billion six hundred million years…”
- “About five billion years from now, the core of the Sun will shrink and become hotter.”
Dịch nghĩa:
“Mặt Trời hiện nay là một ngôi sao lùn vàng. Nó được cung cấp năng lượng bởi các phản ứng nhiệt hạch gần trung tâm, chuyển hóa hydro thành heli. Mặt Trời đã tồn tại ở trạng thái hiện tại khoảng 4,6 tỷ năm và có kích thước lớn hơn Trái Đất hàng nghìn lần.
Bằng cách nghiên cứu các ngôi sao khác, các nhà thiên văn học có thể dự đoán phần còn lại của vòng đời Mặt Trời sẽ như thế nào. Khoảng 5 tỷ năm nữa, lõi Mặt Trời sẽ co lại và trở nên nóng hơn. Nhiệt độ bề mặt sẽ giảm. Nhiệt độ cao hơn ở trung tâm sẽ làm tăng tốc độ của các phản ứng nhiệt hạch. Các vùng bên ngoài của Mặt Trời sẽ mở rộng khoảng 35 triệu dặm, gần bằng khoảng cách tới Sao Thủy, hành tinh gần Mặt Trời nhất. Lúc đó, Mặt Trời sẽ trở thành một ngôi sao khổng lồ đỏ. Nhiệt độ trên Trái Đất sẽ trở nên quá cao để sự sống có thể tồn tại.
Khi Mặt Trời đã sử dụng hết năng lượng nhiệt hạch của nó ở dạng sao khổng lồ đỏ, nó sẽ bắt đầu co lại. Sau khi co lại đến kích thước của Trái Đất, nó sẽ trở thành một ngôi sao lùn trắng. Mặt Trời có thể phát ra lượng lớn khí trong các vụ nổ mạnh mẽ gọi là các vụ nổ tân tinh (nova) khi nó chuyển từ sao khổng lồ đỏ sang sao lùn trắng.
Sau hàng tỷ năm ở trạng thái sao lùn trắng, Mặt Trời sẽ sử dụng hết nhiên liệu và mất nhiệt. Ngôi sao như vậy được gọi là sao lùn đen. Khi Mặt Trời trở thành một sao lùn đen, Trái Đất sẽ tối và lạnh. Nếu vẫn còn khí quyển, nó sẽ bị đóng băng trên bề mặt Trái Đất.”

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 38 to 42.
Reading to oneself is a modern activity which was almost unknown to the scholars of the classicaland medieval worlds, while during the fifteenth century the term “reading” undoubtedly meant readingaloud. Only during the nineteenth century did silent reading become commonplace.
One should be wary, however, of assuming that silent reading came about simply because readingaloud was a distraction to others. Examinations of factors related to the historical development of silentreading have revealed that it became the usual mode of reading for most adults mainly because the tasksthemselves changed in character.
The last century saw a steady gradual increase in literacy and thus in the number of readers. As thenumber of readers increased, the number of potential listeners declined and thus there was somereduction in the need to read aloud. As reading for the benefit of listeners grew less common, so came the flourishing of reading as a private activity in such public places as libraries, railway carriages andoffices, where reading aloud would cause distraction to other readers.
Towards the end of the century, there was still considerable argument over whether books shouldbe used for information or treated respectfully and over whether the reading of materials such asnewspapers was in some way mentally weakening. Indeed, this argument remains with us still ineducation. However, whatever its virtues, the old shared literacy culture had gone and was replaced bythe printed mass media on the one hand and by books and periodicals for a specialised readership onthe other.
By the end of the twentieth century, students were being recommended to adopt attitudes to booksand to use reading skills which were inappropriate, if not impossible, for the oral reader. The social,cultural and technological changes in the century had greatly altered what the term “reading” implied.
Reading aloud was more common in the medieval world because .
