Reading
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 which are 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 equal 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. After the addition is done, 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.
20. What is the main purpose of the passage?
A.To discuss innovative developments in technology

Newspapers and television news programs always seem to report about the bad things happening in society. However, there is a place where readers can find some good news. That place is the website called HappyNews. The man behind HappyNews is Byron Reese. Reese set up HappyNews because he thought other news sources were giving people an unbalanced view of the world. Reese said about HappyNews, “The news media gives you a distorted view of the world by exaggerating bad news, misery, and despair. We're trying to balance out the scale.”
Not everyone agrees with Reese's view, though. Many people think that news sources have a responsibility to provide news that is helpful to people. People need to know about issues or problems in today's society. Then they are better able to make informed decisions about things that affect their daily lives. Reese said that HappyNews is not trying to stop people from learning about issues or problems. HappyNews is just trying to provide a balanced picture of today's world. By the end of its first month online, HappyNews had more than 70,000 unique readers. About 60 percent of those readers were women. Something else unique makes HappyNews different from any of the other news or information websites that are on the Internet. Unlike many other websites, Happy News gets fan mail from its readers on a daily basis.
28. Which of the following is the best title for this passage?
A.“Newspapers vs. Online News”

29. How is HappyNews different than other news sources?
A.Its stories are not about bad things.
B.The website only has stories about women.
C.All of the stories are written by Reese.
D.HappyNews does not exaggerate its stories.
30. The word “they” in paragraph 2 refers to ______.

C. The stories are from around the world.
D. It doesn't tell them about important issues or problems.
