                                                How to take care of the needy

     The charm of a city is not the level of its tolerance (宽容), but the humanistic care and warmth it offers

to disadvantaged groups. Last week, Beijing's urban administration and civil administration departments

began an intensive winter relief camp to persuade people forced to sleep on the streets to move to relief

centers, which was met with a cold response. But the government wouldn't abandon their efforts to help

the needy.

     Actually, it is not new for people used to sleeping on the streets to refuse to shift to relief centers.

There are three main reasons why they do so. First, the lack of understanding among the staff at such

centers has produced a sense of fear and strangeness among destitute people. Second, a relief center is

less convenient for such people and many of them, such as professional beggars, could even lose their

"jobs". And third, many of them know that they would finally be sent back home, which they want to

avoid.

     Since the homeless are quite defensive, it would be better if officials take a friendly and patient attitude

to persuade them to move into relief centers. The officials have to explain to people that relief centers are more comfortable and convenient.

     Besides, the government could build open centers, which are less formal than the existing relief centers, to provide temporary (临时的) place to professional beggars and garbage collectors, instead of forcing

them to return to their villages and towns.

     A more flexible institutional arrangement could help clear the streets of extremely poor people.

     Since the existing relief system is "non-professional", experts argue that more legal methods and

management measures are needed to deal with professional beggars, especially because persuasion alone

cannot stop them from begging.

     Also, more measures have to be taken to make the system perfect.

2. Which of the following words can take the place of "destitute" in the third paragraph?

A. poor          

B. hungry      

C. ordinary        

D. unfriendly

3. What can we conclude from the passage?

A. The charm of a city is decided by the humanistic care offered to disadvantaged groups. 

B. the existing relief centers are not comfortable or convenient.

C. many homeless people welcomed the winter relief program well.

D. the present relief system for beggars is not perfect

4. What is the attitude of the author towards the winter relief camp?

A. positive
