58. Where can you probably find the text?
Two of the saddest words in the English language are “if only”. I live my life with the goal of never having to say those words, because they convey regret, lost opportunities, mistakes, and disappointment.
My father is famous in our family for saying, “Take the extra minute to do it right.” I always try to live by the “extra minute” rule. When my children were young and likely to cause accidents, I always thought about what I could do to avoid an “if only” moment, whether it was something minor like moving a cup full of hot coffee away from the edge of a counter, or something that required a little more work such as taping padding (衬垫) onto the sharp corners of a glass coffee table.
I don’t only avoid those “if only” moments when it comes to safety. It’s equally important to avoid “if only” in our personal relationships. We all know people who lost a loved one and regretted that they had foregone an opportunity to say “I love you” or “I forgive you.” When my father announced he was going to the eye doctor across from my office on Good Friday, I told him that it was a holiday for my company and I wouldn’t be here. But then I thought about the fact that he’s 84 years old and I realized that I shouldn’t give up an opportunity to see him. I called him and told him I had decided to go to work on my day off after all.
I know there will still be occasions when I have to say “if only” about something, but my life is definitely better because of my policy of doing everything possible to avoid that eventuality. And even though it takes an extra minute to do something right, or it occasionally takes an hour or two in my busy schedule to make a personal connection, I know that I’m doing the right thing. I’m buying myself peace of mind and that’s the best kind of insurance for my emotional well-being.
59. Which of the following is an example of the “extra minute” rule?
60. The author decided to go to her office on Good Friday to ______.
61. The underlined word “foregone” in Paragraph 3 is closest in meaning to ______.
62. What is the best title for the passage?
Turning the lights out or wearing a blindfold while eating could be a quick way to lose weight, according to scientists. The simple trick works because it stops diners eating for pleasure rather than for calories. It also triggers (引发) a part of the brain that is worried that unseen food may go bad.
An experiment by the University of Konstanz, in Germany, found that people who were blindfolded consumed nine percent fewer calories before they felt full, compared to those who could see. They also vastly overestimated how much they had eaten because they could not see how much was left on the plate. Blindfolded volunteers estimated they had eaten 88 percent more than they actually had.
Scientists believe that not seeing food on the table also allows the body to know when it is full in real time rather than remembering past experiences where it might have taken a full plate to feel full.
In the experiment, 50 people were blindfolded and 40 were allowed to see their food. All were told not to eat within two hours of the experiment. They were then given three 95g bowls of chocolate ice cream and invited to eat for 15 minutes. Their bowls were taken away and the remaining ice-cream weighed, while the participants were quizzed on how much they thought they had eaten.
On average the group who could see ate 116g while the blindfolded groups ate 105g. However, the blindfolded group believed they had eaten 197g while compared with 159g for the non-blind volunteers. They were also asked how pleasant the ice-cream tasted and the blindfolded group rated lower than those who could see.
“The experienced pleasure of eating was significantly lower in the blindfolded group. Not seeing the food might have decreased the appetite. Sight plays an important role in the eating experience and in the overall dining experience.”
Previous studies have shown that the visual influence of food plays a large part in the taste. While restaurants that allow diners to eat in the dark state that it triggers other senses, in fact eating in darkness is likely to taste far milder than usual.
63. With the lights out, diners eat less partly because ______.
64. We can learn from the passage that the blindfolded group ______.
65. The last two paragraphs tell us that ______.
66. The main purpose of the passage is to ______.
Let us all raise a glass to AlphaGo and the advance of artificial intelligence. AlphaGo, DeepMind’s Go-playing AI, just defeated the best Go-playing human, Lee Sedol. But as we drink to its success, we should also begin trying to understand what it means for the future.
The number of possible moves in a game of Go is so huge that, in order to win against a player like Lee, AlphaGo was designed to adopt a human-like style of gameplay by using a relatively recent development—deep learning. Deep learning uses large data sets, “machine learning” algorithms (计算程序) and deep neural (神经的) networks to teach the AI how to perform a particular set of tasks. Rather than programming complex Go rules and strategies into AlphaGo, DeepMind designers taught AlphaGo to play the game by feeding it data based on typical Go moves. Then, AlphaGo played against itself, tirelessly learning from its own mistakes and improving its gameplay over time. The results speak for themselves.
Deep learning represents a shift in the relationship humans have with their technological creations. It results in AI that displays surprising and unpredictable behaviour. Commenting after his first loss, Lee described being shocked by an unconventional move he claimed no human would ever have made. Demis Hassabis, one of DeepMind’s founders, echoed this comment: “We’re very pleased that AlphaGo played some quite surprising and beautiful moves.”
Unpredictability and surprises are—or can be—a good thing. They can indicate that a system is working well, perhaps better than the humans that came before it. Such is the case with AlphaGo. However, unpredictability also indicates a loss of human control. That Hassabis is surprised at his creation’s behaviour suggests a lack of control in the design. And though some loss of control might be fine in the context of a game such as Go, it raises urgent questions elsewhere.
How much and what kind of control should we give up to AI machines? How should we design appropriate human control into AI that requires us to give up some of that very control? Is there some AI that we should just not develop if it means any loss of human control? How much of a say should corporations, governments, experts or citizens have in these matters? These important questions, and many others like them, have emerged in response, but remain unanswered. They require human, not human-like, solutions.
So as we drink to the milestone in AI, let’s also drink to the understanding that the time to answer deeply human questions about deep learning and AI is now.
67. What contributes most to the unconventional move of AlphaGo in the game?
68. A potential danger of AI is ______.
69. How should we deal with the unpredictability of AI?
70. What’s the author’s attitude towards this remarkable advance in AI?
Being Left-handed ina Right-handed World
The world is designed for right-handed people,but why does a tenth of the population prefer the left? 71
The answer to it remains a bit of a mystery.Since scientists have noticed that left-handedness tends to run in families,it’s assumed that left-handedness has a genetic(基因的)component to it.
72 In fact, identical twins, whoshare the same genes, can sometimes prefer to use different hands. There arealso plenty of theories on what else might determine which hand you write with,but many experts believe that it’s kind of random.
Historically, the left side andleft-handedness have been considered a negative thing by many cultures. 73 In some areas, the left hand became known as the“unclean” hand. In many religions, the right hand of God is the favored hand.For example, Jesus sits at God’s right side. God’s left hand, however, is thehand of judgement. Various activities and experiences become rude or even signsof bad luck when the left hand becomes involved. In some parts ofScotland, it isconsidered bad luck to meet a left-handed person at the start of a journey. 74 A person giving directions will put their left handbehind them and even physically try to point with their right hand ifnecessary. In some Asian countries, eating with the left hand is consideredimpolite.
75 Peoplecome to realize that left-handedness is natural. People even noticed that manyfamous people are left-handed, including Benjamin Franklin, Leonardo Da Vinci,and Charlie Chaplin. Some researchers find out that lefties are more creativeand can deal with abstract thinking better. The left-handedness is more easilyadaptable to the right-handed world as well. Being left-handed is no longer asad story now; instead, it is a wonderful gift or maybe it is something youshould take pride in.

A Very Special Special Olympian
The professor was searching for student volunteers in the lecture room for a Special Olympics event. As the sign-up sheet went up and down the rows, I started to come up with my 36 . Maybe it was the distance to the college where the event was to take place, or the early hour that 37 had to report for duty. Whatever the reasons that made me hesitate, I am thankful to this day that I 38 up volunteering. If I had missed the event, I would have missed one of the most unforgettable moments that I have ever 39 .
I arrived at the volunteer tent bright and early. My task was 40 . I was to stand at the finish line only and wait until the event was over and then take the 41 to the announcing booth(公告处). Standing at the finish line, I was able to witness many amazing efforts and close races. I was most impressed by the effort each athlete put into his or her 42 . What also impressed me was the sincere 43 each athlete expressed while participating though sometimes the joy of participating in a sporting event can get 44 in the fierce competition of winning and losing.
Then an amazing moment happened right before my eyes. A group of athletes were 45
up to run a short race. One of them was in a wheelchair, a little girl with a 46 smile, wearing bright bows in her hair. Her smile filled the stadium that day. I couldn’t help but smile back at her.
The gun sounded. They were off. Runners sped up in the 47 with all their might. My eyes
48 for the little girl with the bright bows. There she was, pumping her arms with all the
49 she had. Her efforts were getting little result, but that did not stop her. I noticed as she got closer that she also had an injured arm. But that did not stop this bright star. The race was long over 50 the young athlete kept pumping her arms. As she finally 51 the finish line, the noise of the crowd was thunderous. There I stood 52 , with tears falling down my cheeks.
After all these years, I can still hear those cheers. I wish I could thank that remarkable athlete for what her efforts 53 this unmotivated college guy. I grew up a lot that day because of the 54 of that little girl in the wheelchair. I was 55 that day of a poem from a book that states, “Whatever you do, do it with all your might.”
