1 . Algorithms (计算程序) are able to do a huge number of tasks, and the number of tasks that they are able to do is expanding practically every day. According to a new study, despite increasing concern over the effect of algorithms in daily life, more and more people nowadays are willing to trust a computer program, especially if a task becomes too challenging. From choosing the next song on your playlist to choosing the right size of pants, people are relying more on the advice of algorithms to help make everyday decisions.
During the study, researchers asked volunteers to count the number of people of a crowd in a photograph and supplied suggestions that were offered by a group of other people and suggestions offered by an algorithm. As the number of people in the photograph expanded, counting became more difficult and people were more likely to follow the suggestions offered by an algorithm rather than count themselves or follow the “wisdom of the crowd”.
One of the common problems with AI is when it is used for awarding credit. While that is a subjective decision, there are lots of numbers there, like income and credit scores. Therefore, people feel like this is a good job for an algorithm. But we know that dependence leads to unfair and incomplete practices in many cases because of social factors that aren’t considered.
Facial recognition and hiring algorithms have come under inspection in recent years because their use has shown cultural prejudice in the way they were built, which can cause inaccuracies when matching faces to identities or screening for qualified job candidates. The prejudice may not be present in a simple task like counting, but their presence in other trusted algorithms is a reason why it is important to understand how people rely on algorithms when making decisions.
“The eventual goal is to look at groups of humans and computers making decisions and find how we can get them to trust each other and how that changes their behaviors,” one of the researchers said. “Because there is very little research in that setting, we’re starting with the fundamentals.”

| B．It will help you to root out password risks altogether. |
| C．Many employees still create weak and simple passwords. |
| D．These bad password habits present a threat to organizations. |
| E．That helps reduce the risk that a bad actor gains access to your systems. |
| F．Unfortunately, the passwords that employees are reusing are often weak. |
| G．However, that's not to say there is no way to reduce or uproot password threats. |
3 . Alida Monaco doesn’t spend her summers doing the usual teenage work, like working at the mall. Instead，she ‘ s studying.
It used to be that a summer job was considered a teenage thing. Today, Monaco ,who has never had a summer job, is part of growing trend (趋势)teenagers focusing on their studies, even during the summer. That’s down from 72% of Americans aged 16 to 19 who worked in July of 1978, according to the U. S. Bureau of Labor Statistics.
Fierce (激烈的)competition, older workers returning to the workforce and weak economic growth are all adding to the decrease of teenagers in the workforce. But as schoolwork grows increasingly heavy and homework eats up more time, data suggest the biggest reason why some teens won’t be working this summer is that they simply don’t1 have time.
For college - bound teens, some teachers even advise students not to waste time on a summer job. “ Some of my students only have about six weeks off in the summer,” said Shannon Reed, a lecturer at the University of Pittsburgh and a former high school English teacher.” I could never advise that they get jobs during that short break. ”
Young people who don’t work may miss out on valuable skills that they’11 need control and help people learn to deal with adult situations. But Monaco, who plans to attend Harvard, isn’t fazed by her lack(缺乏)of work experience. “Maybe I have missed out on a couple of life skills, “she said. “ But I don’t think it will harm me in way .”

4 . Almost one in five drivers had dozed off behind the wheel, a shocking news report had showed. Of those who were dozing off, 29% have done so with their cars speeding at 70 miles per hour. The report also found a quarter of men have fallen asleep while driving, making it almost twice as many as women.
The Safety on Wheel Report, by Post Office Insurance, also looked at how often tiredness or a lack of concentration caused accidents. Three in ten drivers have experienced an accident, from passing a walker crossing to hitting another vehicle, because of a lack of concentration. Meanwhile, almost half (49%) of UK drivers have driven when they do not concentrate.
Paul Havenhand, head of insurance at Post Office, said, “ When tiredness strikes, drivers should avoid the roads.” There is no measurement for tired driving, unlike driving under the influence of alcohol, yet it could result in an equally dangerous accident.
Drivers are advised to take a 15-minute break from driving every two hours. However, a third (36%) are so eager to reach their destination that they will ignore feelings of tiredness. What’s more, almost one in five (18%) will drive for longer than four hours without a break, while 6% carry on for up to 6 hours. Just over a quarter (27%) choose a quick stop to buy a cup of coffee, which is a very popular way for drivers to get rid of tiredness, and only 17% stop to have a rest until they feel energetic again. Mr. Havenhand added, “Drivers should plan ahead and rest before starting a long journey; besides, they can take regular breaks to recharge their batteries while on road; in some cases, if they do feel too tired to concentrate on the roads, they could consider an alternative means of transport.”
1. Which suggestion is NOT put forward by Mr. Havenhand?| A．Preparing well for a long journey and taking a complete rest before it. |
| B．Having breaks regularly in order to feel refreshed. |
| C．Choosing another method of transport instead. |

| B．Get back their energy by resting for a while. |
| C．Accuse them of stealing batteries. |
| D．Pay twice more money for their batteries. |
| A．drinking coffee |
| B．talking with others |
| C．ignoring feelings of tiredness |
| D．singing songs |
| A．To warn people of the danger of tired driving. |
| B．To tell people to be careful when walking on the street. |
| C．To inform people of the importance of a good rest. |
| D．To introduce some dangers while driving on the roads. |
Technological change is everywhere and affects every aspect of life, mostly for the better. However, social changes are brought about by new technology are often mistaken for a change in attitudes.
An example at hand is the involvement of parents in the lives of their children who are attending college. Surveys (调查) on this topic suggests that parents today continue to be “very” or “somewhat” overly-protective even after their children move into college dormitories. The same surveys also indicate that the rate of parental involvement is greater today than it was a generation ago. This is usually interpreted as a sign that today’s parents are trying to manage their children’s lives past the point where this behavior is appropriate.
However, greater parental involvement does not necessarily indicate that parents are failing to let go of their “adult” children.
In the context (背景) of this discussion, it seems valuable to first find out the cause of change in the case of parents’ involvement with their grown children. If parents of earlier generations had wanted to be in touch with their college-age children frequently, would this have been possible? Probably not. On the other hand, does the possibility of frequent communication today mean that the urge to do so wasn’t present a generation ago? Many studies show that older parents — today’s grandparents — would have called their children more often if the means and cost of doing so had not been a barrier.
Furthermore, studies show that finances are the most frequent subject of communication between parents and their college children. The fact that college students are financially dependent on their parents is nothing new; nor are requests for more money to be sent from home. This phenomenon is neither good nor bad; it is a fact of college life, today and in the past.
Thanks to the advanced technology, we live in an age of bettered communication. This has many implications well beyondthe role that parents seem to play in the lives of their children who have left for college. But it is useful to bear in mind that all such changes come from the technology and not some imagined desire by parents to keep their children under their wings.

7 . The word addiction usually makes you think of alcohol or drugs.
The question is: why do they have this addiction? There isn’t a specific answer. Some people go shopping when they are sad, worried, upset or lonely and they want to feel better. They use this activity as a way to forget their problems. Shopaholics say that they feel more important and better after they buy something.
Shopaholism seems to be a harmless addiction, but it can bring out problems. Some of them can be psychological. If this is the case, people addicted to shopping should go to a support group to help them break this habit. However, the process, like for most addictions, is long, and they suffer a lot.
