People under eighteen ______ to buy strong drinks or cigarettes in some countries. (not allow)

Most people don't enjoy facing the difficult situations that sometimes occur with coworkers in the workplace. Such situations may arise from honest disagreements over design or engineering issues, personnel or benefits matters, management decisions or actions, or from any other situation where human impressions and objectives differ.

There could be double trouble for engineers who are more likely to feel at home with electrons and bytes(信息组), and behave in highly predictable ways, than with coworkers, who often appear arbitrary and unpredictable. For those of us who have internalized the strict and measurable rules of the physical world, dealing with other people can be both disappointing and frustrating.

Yet how you manage situations of conflict with your coworkers could have a significant impact on your career, often even more than your engineering prowess or your design skills. Those who deal successfully with potential conflicts are far more likely to receive added responsibilities and promotions, in addition to the pay increases and respect that come with them. On the other hand, not dealing successfully with conflict can potentially relegate you to a career backwater, with technical challenges and high pay passing you by.

Why is dealing with conflict an important skill today? It's primarily because there's more of it now than in the past. Workers of all types are more likely to speak up for their own ideas or actions, rather than follow the dictating corporate chain of command. Conflict also sometimes arises as a result of unclear company goals, or when those goals aren't shared equally by all. Rather than working for a single common good, employees and managers seek individual goals, such as promotion, job security, experience, money, and even the proverbial free lunch.

Not only is actual conflict greater today, but even the potential for interpersonal conflicts in the workplace is far greater than at any time in the past. One reason for this is increased time-to-market pressures. The need to rapidly make decisions, establish an engineering direction, and meet project milestones adds elements of tension and stress to an already difficult endeavor.

This makes the workplace a potential minefield for interpersonal conflict. It's especially apparent to an engineer in a position of responsibility, like a project leader or an engineering manager. For an engineer who must work with others to complete a project, the need to manage conflict can spell the difference between success and failure.

Which of the following statements is true' according to the passage?

A．Minefields are becoming common in the workplace.

B．Workplace conflict can arise from honest disagreements.

C．Workers today are less equipped to deal with workplace conflict.

D．Companies are finding new ways to deal with workplace conflict.

The Need to Remember

Some people say they have no memory at all: "I just can&39;t rememB．er athing !" B．ut of coursewe all have amemory. Our memory tells us who we are. Our memory helps us to make use in thepresent of what we have learnt in the past.

In fact we have different types of memory. For example, our visual memory helps us recallfacts and places. Some people have such astrong visual memory that they can remember exactlywhat they have seen, for example, pages of abook, as acomplete picture.

Our verbal( 言语的 )memory helps us rememB．er words and figures we may have heard butnot seen or written: Items of ashopping list, achemical formula, dates, or arecipe.

With our emotional(情感的)memory, we recall situations or places where we had; strongfeelings, perhaps of happiness or unhappiness. We also have special memories for smell, taste,touch and sound, and for performing physical movements.

We have two ways of storing any of these memories. Our short-term memory stores items forup to thirty seconds--enough to remember atelephone number while we dial. Our long-term mem-ory, on the other hand, may store items for alifetime. Older people in fact have amuch biterlong-term memory than short-term. They may forget what they have done only afew hours ago, buthave the clearest remembrance (记忆) of when they were very young.

Psychologists tell us that we only remember afew facts about our past, and that we invent therest. It is as though we remember only the oudine of astory. We then make up the details. We of-ten do this in the way we want to remember them, usually so that we appear as the heroes of ourown past, or maybe victims needing sympathy (同情).

We have two ways of storing any of these memories. Our short-term memory stores items for up to thirty seconds enough to remember a telephone number while we dial. Our long-term memory, on the other hand, may store items for a lifetime. Older people in fact have a much better long-term memory than short-term. They may forget what they have done only a few hours ago, but have the clearest remembrance (记忆) of when they were very young.

Psychologists tell us that we only remember a few facts about our past, and that we invent the rest. It is as though we remember only the outline of a story. We then make up the details. We often do this in the way we want to remember them, usually so that we appear as the heroes of our own past or maybe victims needing sympathy (同情).
