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.

In the history of technology, computers and calculators were innovative developments. They are essentially different from all other machines because they have a memory. This memory stores instructions and information. In a calculator, the instructions are the various functions of arithmetic, which are permanently remembered by the machine and cannot be altered or added to. The information consists of the numbers keyed in.

An electronic pocket calculator can perform almost instant arithmetic. A calculator requires an input unit to feed in numbers, a processing unit to make the calculation, a memory unit, and an output unit to display the result. The calculator is powered by a small battery or by a panel of solar cells. Inside is a microchip that contains the memory and processing units and also controls the input unit, which is the keyboard, and the output unit, which is the display.

The input unit has keys for numbers and operations. Beneath the key is a printed circuit board containing a set of contacts for each key. Pressing a key closes the contacts and sends a signal along a pair of lines in the circuit board to the processing unit, in which the binary code for that key is stored in the memory. The processing unit also sends the code to the display. Each key is connected by a different pair of lines to the processing unit, which repeatedly checks the lines to find out when a pair is linked by a key.

The memory unit stores the arithmetic instructions for the processing unit and holds the temporary results that occur during calculation. Storage cells in the memory unit hold the binary codes for the keys that have been pressed. The number codes, together with the operation code for the plus key, are held in temporary cells until the processing unit requires them.
When the equals key is pressed, it sends a signal to the processing unit. This takes the operation code-for example, addition-and the two numbers being held in the memory unit and performs the operation on the two numbers. A full adder does the addition, and the result goes to the decoder in the calculator's microchip. This code is then sent to the liquid crystal display unit, which shows the result, or output, of the calculation.

The word "contacts" in paragraph 3 is closest in meaning to

A. commands

B. codes

C. locations

D. connections

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.

Education is another area of social life in which information technology is changing the way we communicate. Today’s college students may not simply sit in a lecture or a library to learn about their field. Through their computers and the wonders of virtual reality they can participate in lifelike simulated experiences and consider the following scenario of the future of education made possible through developments in information technology.

For children over the age of 10, daily attendance at schools is not compulsory. Yet, some of the older children attend school only once or twice weekly to get tutoriol support or instruction from a teacher. For the most part, pupils are encouraged to work online from home. Students must complete a minimum number of study hours per years; however, they may make up these hours by studying at home at times that suit their family schedule. They can log on early or late in the day and even join live classes in other countries. In order to ensure that each student is learning adequately, computer software will automatically monitor the number of hours a week each student studies online as well as that students’ learning materials and assessment activities. Reports will be available for parents and teachers. The software can then identify the best learning activities and condition for each invidual student and generate similar activities. It can also identify areas of weak achievement and produce special programs adjusted to the students’ needs.

Question23:  What is the topic of the passage? 

A.  Students don’t have to go to school any more.

B.  Computer software will make sure students learn at home.

Question24:  How many times are children who are older than 10 required to go to school weekly? 

A. No time. B. Three.            C. Four.             D. Once or twice.

Question25:  What counts the number of hours per week that students spend learning? 

A.  Virtual reality. B.  Teacher.

C.  Computer software. D.  Parents.

Question26:  What CAN’T the software do? 

A.  Find out the best activities for the students.

B.  Design materials for the students. 

C.  Identify weaknesses of the students.

D.  Monitor the time the students learn.

Question27:  What is NOT MENTIONED as a benefit of information technology to the students? 

A.  Students’ learning time won’t be monitored.

B.  Students’ weak achievement can be identified.

C.  Students can learn at times that suit their schedule.
