A father’s concern that smartphone is depriving him of his precious family time does not stand alone. Favorable opinions as there are, the majority of Americans today view technology as hazardous. (31 words)
【选“是”】
However, no pains, no gains. The world evolves as human technology leaps forward, along whose process there is bound to be sacrifices. The definition of happiness may vary, but a more connected, convenient, and creative society is undeniably nothing a modern man wouldn’t have desired. With digital devices booming around, we are given so many choices that our minds have been freed to a degree our ancestors could never anticipated.
That being said, to make sure technology doesn’t get in the way, you need to unplug from the information highway and share your journey with your family and friends from time to time. A balance between man and computers will lead to an ultimate happiness. (115 words)
【选“否”】
True, a high-tech world seems a new Eden, but it won’t last any longer than the old one. Putting down their phones, lifting up their misty eyes, and waking up at night, people suddenly realize that, with all their family living by, they are alone. Children forgot how and why they should return their parents’ love because it were never given; classic literature is left rotten on the shelves because no one bothers to look away from their screen.
To stop yourself getting “high” instead of “happy”, read a book, go outdoors, or simply pay a visit to your parents. There are things to pursue in life other than thumbing up tweets. Enjoy a tech-free day and see what real happiness means. (122 words)

Good morning! I’m Samuel Davis, and this is the ten o’clock news report. I hope everyone is having a fine Monday morning. It’s getting pretty wet out there, so grab an umbrella and stay dry! (17) I’m here today with Matt Miller, who has completed his 29,000-mile journey in just six weeks, with a total of 180 hours in flight. Beginning in California, he made twenty-five stops in fourteen different countries including England, Italy, Greece, Egypt, and Thailand. (18) His final trip was a sixteen-hour flight from Hawaii back to California, just half an hour less than his longest flight from Samoa to Hawaii. (19) Born in South Dakota, Matt is a freshman at Massachusetts Institute of Technology, and has said that as a child he was scared of flying. All of that changed when he received his pilot license at just seventeen. After that, he only spent a few years planning everything out before beginning his journey around the world. Matt is here with us today for an interview. Welcome Matt! First, why don’t you tell all our listeners about the craziest thing you saw during your adventure? (20)
