He further explained that transitors control the flow of electric current in electronic equipment. He wanted to know which popular technological invention cannot operate without transistors. Most students agreed, it is the personal computer. Professor Sanchez then asked if the students know how do transitors function in computers. He said that the transitors were etched into tiny silicon microchips and that these transistors increase computer’s speed and data storage capacity. Then he asked the class when had transitors been invented. Sergei guessed that they were invented in 1947. The professor said that he is correct. Professor Sanchez then asked what was the importance of this invention. Many students answered that it is the beginning of the information age. At the end of the lecture, the professor assigned a paper on transistors. He requested that each student chooses a topic by next Monday. He suggested that the papers are typed.

Professor Sanchez gave a lecture on transistors last Tuesday. First, he explained what transistors are. He said that they are very small electronic devices used in telephones, automobiles, radios, and other electronic equipment. He further explained that transistors control the flow of electric current in these devices. He then questioned the students on which popular technological invention cannot operate without transistors. Most students agreed that it is the personal computer. Professor Sanchez then asked if the students knew how transistors function in computers. He explained that transistors are etched into tiny silicon microchips, and these transistors increase the computer's speed and storage capacity. He also asked the class when transistors were invented. Sergei guessed that they were invented in 1947, which the professor confirmed as correct. Professor Sanchez then asked about the significance of this invention. Many students answered that it marked the beginning of the information age.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.

There was a man who had four sons. He wanted his sons to learn not to judge things too quickly. So he sent them each on a quest, in turn, to go and look at a pear tree that was a great distance away. The first son went in the winter, the second in the spring, the third in summer, and the youngest son in the fall. When they had all gone and come back, he called them together to describe what they had seen.

The first son said that the tree was ugly, bent, and twisted. The second son said no – it was covered with green buds and full of promise. The third son disagreed, he said it was laden with blossoms that smelled so sweet and looked so beautiful, it was the most graceful thing he had ever seen. The last son disagreed with all of them; he said it was ripe and drooping with fruit, full of life and fulfilment.

The man then explained to his sons that they were all right, because they had each seen but one season in the tree’s life. He told them that you cannot judge a tree, or a person, by only one season, and that the essence of who they are – and the pleasure, joy, and love that come from that life – can only be measured at the end, when all the seasons are up. If you give up when it’s winter, you will miss the promise of your spring, the beauty of your summer, fulfilment of your fall.

Don’t judge a life by one difficult season. Don’t let the pain of one season destroy the joy of all the rest.

(source: https://www.beliefnet.com)

According to the paragraph 2, what did the second son see in his turn?

A.The tree was gloomy, withered and crooked.

B.The tree was in buds and teeming with vigor.

C.The tree was blossoming and gave off a sweet scent.

D.The tree was bountifully fruitful, brimming with life force.

Đáp án B

Theo đoạn 2, người con trai thứ hai đã nhìn thấy gì trong lượt của mình?

Cây ảm đạm, khô héo và cong queo.

Cây đã đâm chồi và tràn đầy sức sống.

Cây đang nở hoa và tỏa ra hương thơm ngào ngạt.

Cây có nhiều hoa quả, tràn đầy sức sống.

Căn cứ vào thông tin đoạn 2:

The first son said that the tree was ugly, bent, and twisted. The second son said no – it was covered with green buds and full of promise. (Người con trai đầu tiên nói rằng cái cây trông xấu xí, cong queo. Người con trai thứ hai nói không - nó chi chít những nụ màu xanh và đầy sức sống.)
