One of my favourite things to do is hiking in mountains. Because nobody likes the idea of getting lost, I always prepare before every trip. But what’s the best navigation tool, a Global Positioning System (GPS) or a good old map and compass? Five of my friends and I hiked through the mountains on a trail I marked. One team of three carried a GPS, and the other team used a map and compass.

It took the GPS team 3 hours and 11 minutes to get through the whole hike, however, it took the map and compass team only 2 hours and 49 minutes. The biggest problem the GPS team met was that they lost the satellite signal (卫星信号) in some places. With no map or compass, they had to walk around until they were in a place where the signal was good. The map and compass team was able to spot (认出) different landmarks, compare them to their maps and then use the compass to point them in the right direction.

When I head out on my future hikes, I’m bringing a map, a compass and a GPS to show me the way.

     "A good parent" can be a confusing phrase. It is almost impossible for one person to be "a good

parent" at all stages of a child's life. Some parents are at their best before their children begin to speak.

Others are most successful before their children enter elementary school. Still others make their finest

contribution to older children or teenagers. Every parent can understand one stage of a child's

development better than another. It is hard for a person to possess superior capacities throughout the

entire period of a child's growth.

     A mother might be "a good parent" from her baby's birth until it is three; that is the period when it

needs her protection and loving care. Then the start of her child's independence might upset and alarm

her, and she might then become less helpful for a few years. A father might be awkward and

uncomfortable with a younger child, but could turn into an excellent parent when the child is old enough

to be taught the skills of cycling, fishing and so on, or to be taken on trips. Some parents feel easier with

boys, and others with girls - and then only at certain ages or stages.

     It is important for parents to understand and accept their own limitations in these matters, just as they

must accept the child's faults of personality and limitations of talent. Otherwise, fathers and mothers will

feel guilty and blame themselves for weaknesses that may not be their faults. Much of the guilt

experienced by modern parents comes from the mistaken feeling that they ought to be all things at all

times to the child, which is clearly mistaken. In past ages, grandparents and uncles and aunts lived with

the family, and provided different kinds of support; in our present "nuclear" family, too many roles are

demanded of the two parents, which they cannot possibly fulfill.

1. Confusion arises about what it means to be "a good parent" because __________.

A. it is normal to be a successful parent during most stages of a child's development

B. most parents are only good at helping older children or teenagers

C. parents are usually at their best before their children go to school

D. parents do not realize they cannot perform equally well through a child's growth

2. Parents would feel guilty if __________.

A. their children can't accept their own limitations of talent

B. they realize their weaknesses in raising children

C. their grandfathers and uncles and aunts don't live with them

D. they don't know their limitations in raising children

3. Parents of "nuclear" families sometimes feel at a loss because __________.

A. they believe that such a family prevents the healthy growth of a child's personality and talent

B. they dislike the support that other family members give to their children

C. they do not always have the help of other family members in child-raising

D. they no longer regard grandparents, uncles and aunts as good educators of their children
