Do you read reviews after you see a movie? I used to do that, but I usually regret. I read so much about a movie on advance that I often ended up not go to see it at all. The writers point out everything that's wrong with the film, but seldom mentions anything good about them. They also tell many things and even the ending of the movie. Lately I have changed way I choose movies to watch. I read reviews afterwards. What's importance to me is that I don't watch the talk shows in that people discuss movies, I don't ask others how they like of it. Now, I enjoy myself even more.

【題目】閱讀理解
Television has turned 88 years old onSeptember 7, 2015, and it has never looked better. In its youth, television wasa piece of furniture with a tiny, round screen showing unclear pictures oflow-budget programs. In spite of its shortcomings, it became popular. Between1950 and 1963, the number of American families with a television jumped from 9%to 92% of the population.
As the audience got larger, thetechnology got better. Television sets became more reliable through the 1960s.The reception (接收效果)improved. The picture improved. The major networks started broadcastingprograms in color.
Even greater improvements were comingaccording to Sanford Brown, who wrote an article for the Post in 1967.Surprisingly, just about every prediction he made in the article became areality. For example: All sets in the not-distant future will be colorinstruments. He also predicted that TV sets would become smaller, simpler, morereliable and less expensive and may forever put the TV repairman out of work.Smaller sets do not, of course, mean smaller screens. TV engineers expectscreens to get much bigger. However, today’s 3-D TV is even farther away, ifit’s coming at all. There is some doubt whether the public would be eager topay for it, in view of people’s cold reception given to 3-D movies.
But the technology with the greatestpotential, according to Brown, was cable television (有線電視), whichwas still in its early stages then. As he predicted, the future of cabletelevision was highly interactive (互動的). It wasn’t cable television that gaveAmericans their electronic connection to the world, however. It was theInternet. He even foresaw the future office: using picture phones, big-screentelevisions for conferences, and computers providing information at the touchof a button.
Brown ever said, “The future oftelevision is no longer a question of what we can invent. It’s a question ofwhat we want.”
（1）What can we infer about television sets in the 1960s?
A.They were very popular with Americans.
B.The reception showed no improvement.
C.They showed black-and-white pictures.
D.They were out of order now and then.
（2）Which of the followings did Sanford Brown fail to predict?
A.Television’s good quality.
B.The invention of 3-D TV.
C.The future office’s model.
D.The potential of cable TV.
（3）What is the text mainly about?
A.The shortcomings of television.

【題目】Billionaire Bill Gates has offered the many thousands of graduates some career and life advice. Over a series of 14 tweets in his Tweeter posted last Monday, the world’s richest man used the words “impact”, “happiness” and “progress”. He did not mention money. Instead, he told the graduates what jobs he would be looking for if he started out today.

“AI (artificial intelligence), energy and bio-sciences are promising fields where you can make a huge influence”, he wrote. Earlier this year, Gates---who famously dropped out of Harvard to found Microsoft---said that artificial intelligence had “ phenomenal” potential, and “anything connected with that would be an exciting lifetime career.” In the same speech at Columbia University, he said there is a huge growing demand in the energy field to develop reliable, cheap and clean energy.

As well as urging new graduates to surround themselves with people who challenge you, teach you, and push you to be your best self, Gates reminded them to think of others, especially the less fortunate.

He wrote that it had taken him decades to learn about the world’s worst unfairness and described this lack of early understanding as his one big regret. “You know more than I did when I was your age,” he wrote, “ You can start fighting unfairness, whether down the street or around the world sooner.”

He finished by asking graduates to consider the progress human has already made, saying that he believe the world is getting better. “ That matters because if you think the world is getting better, you want to spread the progress to more people and places.”

【1】Who has been given life advice by Gates recently?

A. High school students. B. New employers.

C. Unemployed persons. D. College graduates.

【2】What words mentioned in Gates’ tweets?

A. Impact, happiness, money.

B. Impact, happiness, progress.

C. Happiness, progress, money.

D. Progress, impact, money.

【3】What does the underlined word “that” in Para 3 refer to?

A. AI. B. Energy. C. Bio-sciences. D. Microsoft.

【4】What was Gates’ great regret about unfairness?

A. Not fighting with it.

B. Few people realized it.

C. Having too little early understanding of it.

D. Spending too little time learning about it.
