I. Read the following text then answer the questions that follow by circling its corresponding letter marked A, B, C, or D. Ever since humans have inhabited the earth, they have made use of various forms of communication. Generally, this expression of thoughts and feelings has been in the form of oral speech. When there is a language barrier, communication is accomplished through sign language in which motions stand for letters, words, and ideas. Tourists, the deaf and the mute have had to resort to this form of expression. Many of these symbols of the whole words are very picturesque and exact and can be used internationally; spelling, however, cannot. Body language transmits ideas or thoughts by certain actions, either intentionally or unintentionally. A wink can be a way of flirting or indicating that the party is only joking. A nod signifies (biểu thị) approval, while shaking the head indicates a negative reaction. Other forms of nonlinguistic language can be found in Braille (a system of raised dots read with the fingertips), signal flags. Morse code (mã Mooc-xơ), and smoke signals. Road maps and picture signs also guide, warn, and instruct people. While verbalization is the most common form of language, other systems and techniques also express human thoughts and feelings. Question 1: The word “these” in the first paragraph refers to____. A. tourists B. the deaf and the mute C. thoughts and feelings D. sign language motions Question 2: Which form other than oral speech would be most common used among blind people? A. Picture signs B. Braille C. Body language D.Signal language Question 3: How many different forms of communication are mentioned here? A. 5 B. 7 C. 9 D. 11 Question 4: The word “ wink “ in the second paragraph means most nearly the same as A. close one eye briefly B. close two eyes briefly C. nod the head up and down D. shake the head from side to side Question 5 People need to communicate in order to A. create language barriers B. keep from reading with their fingertips C. be picturesque and exact D. express thoughts and feelings

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 following questions

In Science, a theory is a reasonable explanation of observed events that are related. A theory often involves an imaginary model that helps scientists picture the way an observed event could be produced. A good example of this is found in the kinetic molecular theory, in which gases are pictured as being made up of many small particles that are in constant motion.

A useful theory, in addition to explaining past observation, helps to predict events that have not as yet been observed. After a theory has been publicized, scientists design experiments to test the theory. If observations confirm the scientists' predictions, the theory is supported. If observations do not confirm the predictions, the scientists must search further. There may be a fault in the experiment, or the theory may have to be revised or rejected.

Science involves imagination and creative thinking as well as collecting information and performing experiments. Facts by themselves are not science. As the mathematician Jules Henri Poincare said: "Science is built with facts just as a house is built with bricks, but a collection of facts cannot be called science any more than a pile of bricks can be called a house."

Most scientists start an investigation by finding out what other scientists have learned about a particular problem. After known facts have been gathered, the scientist comes to the part of the investigation that requires considerable imagination. Possible solutions to the problem are formulated. These possible solutions are called hypotheses. In a way, any hyphthesis is a leap into the unknown.It extends the scientist's thinking beyond the known facts. The scientist plans experiments, performs calculations, and makes observations to test hypotheses. For without hypotheses, further investigation lacks purpose and direction. When hypotheses are confirmed, they are incorporated into theories.

A useful theory, in addition to explaining past observation, helps to predict events that have not as yet been observed. After a theory has been publicized, scientists design experiments to test the theory. If observations confirm the scientists’ predictions, the theory is supported. If observations do not confirm the predictions, the scientists must search further. There may be a fault in the experiment, or the theory may have to be revised or rejected.

Science involves imagination and Creative thinking as well as collecting information and performing experiments. Facts by themselves are not Science. As the mathematician Jules Henri Poincare said: “Science is built with facts just as a house is built with bricks. But a collection of facts cannot be called Science any more than a pile of bricks can be called a house.”

Most scientists start an investigation by finding out what other scientists have learned about a particular problem. After known facts have been gathered, the scientist comes to the part of the investigation that requires considerable imagination. Possible Solutions to the problem are formulated. These possible Solutions are called hypotheses. In a way, any hypothesis is a leap into the unknown. It extends the scientist’s thinking beyond the known facts. The scientist plans experiments, performs calculations, and makes observations to test hypotheses. For without hypotheses, further investigation lacks purpose and direction. When hypotheses are confirmed, they are incorporated into theories.

Đáp án C 
Theo đoạn văn thứ 2, một học thuyết có ích là học thuyết mà giúp các nhà khoa học
A. quan sát các sự kiện C. đưa ra những dự đoán
B. công khai những phát minh của mình D. tìm ra lỗi trong những thí nghiệm đã qua
“A useful theory, in addition to explaining past observation, helps to predict events that have not as yet been observed.” (Một học thuyết hữu ích, thêm vào việc giải thích những quan sát trước đó, thì phải giúp dự đoán các sự kiện mà vẫn chưa quan sát được.)
