    Blind people usually possess one advantage over other people who can see. Their sense of hearing is far more acute. Bats, whose sight is poor, use a sound location system to help them avoid blocks in the dark. They send out pulses of sound waves, pitched at 50,000 cycles per second, far above the limits of the human ear, which can hear sounds up to frequencies of about 20,000 cycles per second. As the echoes bounce back off obstacles such as trees and walls, the bats are able to take proper action.

    The first steps to help blind people to see with sound are based on exactly the same principle. The sound is given off by an ultrasonic (超声的) torch, whose shape is different from a normal electric torch. It is double-barreled. It works in a similar way to a sonar (声呐) unit on a warship or submarine. The unit's transmitter sends out pulses of ultrasonic waves at the same frequency as the bat and the receiver picks up the returning echoes. Because these are still above the frequency at which the human ear can pick them up. The echoes are filtered (过滤) through circuits that turn them into “bleeps” which can be clearly heard before passing them into headphones.

    This means that a person holding the torch can point it ahead of him and scan the area for obstacles over a range of about 25 feet. If there are no return echoes coming through the headphones, then there is nothing in the way. If echoes do come back, then the closer the obstruction the faster the succession of bleeps and the deeper the pitch of each bleep. With practice, the torch could help a blind person to lead a more normal life.

    At present, the experimental ultrasonic torch requires a shoulder bag to carry the batteries, cables for the power supplies and earphones, as well as the torch itself. Fortunately, reducing the size of the electronic equipment is progressing and it should not be long before the whole set-up can be reproduced in a form small enough to fit into a pair of glasses. The wearer would face in the direction he wanted to check, and lift or lower his head just as a sighted person would.

(1)、Which statement of the following is NOT true according to the article?
A、Bats can avoid blocks in the dark. B、Blind people have more acute sense of hearing than normal people. C、The shape of ultrasonic torch is different from a normal electric torch. D、The ultrasonic torch doesn't send out the same pulse frequency as the bat does.

a. Helping the blind to walk.

b. Helping deaf children to watch sports.

c. Helping the blind to lead a better life.

d. Being used in a warship or submarine during a war.

A、a b B、a c C、a d D、b c
(3)、What can we infer from this article?
A、The ultrasonic glasses have been produced. B、The blind with the ultrasonic torch can walk themselves. C、The blind should not go further without return echoes. D、The filtered bleeps would be passed on to their ears.
(4)、What is the main idea of the passage?
A、The ultrasonic torch can improve the life of the blind. B、Animals can help scientist invent new equipment. C、The technology is progressing rapidly. D、The ultrasonic torch is not easy to carry now.

    Many independent Chinese women like to earn their own bread, even if their husbands are already bringing home the bacon. But a recent survey suggests that such women find more joy from relationships, rather than successful careers.

    About 73 percent of the 7,000 women surveyed in Beijing, Shanghai and Guangzhou said they would choose to work even if their husbands earned enough for the family. The survey also found that 77 percent define happiness as "enjoying a relationship".

    But striking a balance between career and family can bring challenges to the woman's career advancement.

    "In my company, women usually have an equal or even a higher starting salary than men," said Li Hua, general manager of Beijing Chuangjiashe Book Circulation Company. "However, as they begin to climb up the career ladder, women often meet problems along the way, while men can climb the ladder more easily."

    Both physical and emotional differences can prevent some women from taking tough positions, Li said. But family life is often the main difficulty for Chinese career women.

    Despite these challenges, however, some experts believe it's reasonable for some women to want to be breadwinners.

    "In this way, the roles of a family are decided by the parents' abilities rather than their gender(性别)," said Gu Donghui, a sociology professor at Fudan University.

    Gu says women should have the freedom to decide if they want to stay at home or work to support the family. "Everyone has a different interpretation(解释)of what it means to find self-worth".

    Wang Haibin, an economic expert from Renmin University shares that view: "Traditionally, we tend to regard the family as the cell unit of society. Some members have always been expected to make sacrifices for it. But, it really doesn't matter who earns more. Economic independence and personal choice is essential for both sexes in the family."

    Generally speaking, people like those who have a good sense of humor.

    Sometimes a touch of humor might well enable us to win. Consider the case of a young friend of mine, who hit a traffic jam on his way to work shortly after receiving an ultimatum (最后通牒) about being late on the job. Although there was a good reason for Brian's being late—serious illness at home—he decided that this by-now-familiar excuse wouldn't work any longer. His boss was probably already pacing up and down preparing a dismissal speech.

    Yes, the boss was, as Brian entered the office at 9:35. The place was as quiet as a locker room (更衣室): everyone was hard at work. Brian's boss came up to him. Suddenly, Brian forced a smile and stretched out his hand. "How do you do!" he said. "I'm Brian. I'm applying for a job, which, I understand, became available just 35 minutes ago. Doesn't the early bird get the worm?"

    The room exploded in laughter. The boss clamped off a smile and walked back to his office. Brian had saved his job, with the only tool that could win—a laugh.

    Humor is a most effective, yet frequently neglected means of handling the difficult situations in our lives. It can be used for patching up differences, apologizing, saying "no", criticizing, getting the other fellow to do what you want without his losing face. For some jobs, it's the only tool that can succeed. It is a way to discuss subjects so sensitive that serious dialog may start a quarrel. For example, many believe that comedians on television are doing more today for racial and religious tolerance (忍受力) than people in any other forum.

    Do you find it difficult to put down your mobile phone?

    If yes, you're not alone. These days, many people suffer from the stress of FOMO (fear of missing out). They reach for their mobile phones when they wake up in the morning, and for the rest of the day, they constantly scroll down (向下滚动) the timelines of their social media apps to get the latest updates.

    Despite the convenience smartphones bring, many people struggle with their digital habits.

    As Sameer Samat, US tech Company Google's vice president of product management, said in his speech at the 2018 Google I/O developer conference on May 8, 70 percent of people don't want to spend so much time on their phones.

    This is why during the conference Google introduced an app called Dashboard for the new version (版本) of its Android operating system. This new app includes well-being functions that aim to help users manage the time they spend on their digital devices.

    It all starts with a bird's-eye view. Dashboard allows users to look at all the details of their phone habits. For example, a user can see how many times they've unlocked their phone and how many times they've checked their social media apps, as well as how much time they spend on each app every day.

    Once the users see this information, they'll be able to make some changes. With the App Timer function, users can set a time limit for how long they can use each app for every day. After they've hit the limit, they won't be able to launch the app until the next day.

    But even if users become more mindful of their usage, they're still likely to be drawn in by notifications (通知). This is where the Shush feature comes in. It automatically (自动地) silences incoming calls and notifications when a user puts their phone face down.

    If people truly want to make full use of their free time instead of losing hours using their smart phones, these new functions are just one way of doing that.

After all, who needs to use an app to stop you from using other apps when the easiest answer would be just to use your willpower?
