- 根据以下内容回答题:<br>A youngster"s social development has a profound effect on his academic progress.Kids who have trouble getting along with their classmates can end up behind academically as well and have a higher chance of dropping out(退学).In the early grades especially,experts say,youngsters should be encouraged to work in groups rather than individually so that teachers can spot children who may be having problems making friends.“When children work on a pro-ject,”says Lillian Kate,an educational professor at the University of Illinois,“they learn to work together,to disagree,to think to take turns and lighten tensions.These skims can’t be learned through lecture.We all know people who have wonderful technical skills but don’t have any social skills.Relationships should be the first R.”At a certain age,children are also learning to judge themselves in relation to others.For most children,school marks the first time that their goals are not set by an internal clock but by the outside world.Just as the l-year-old struggling to walk the 6-year-old is struggling to meet adult expectations.“Young kids don’t know how to distinguish early-childhood education for the state of New Jersey,if they try hard to do something and fail,they may conclude that they will never be able to accomplish a particular task.The effects is serious,”says Hills,“a child who has had his confidence really damaged needs a rescue operation.”<br>The author seems to think that a kid’S poor relationship with his classmates would__________ .

- 根据以下内容回答题:The greatest recent social changes have been in the lives of women.During the twentieth century there has been a remarkable shortening of the proportion of a woman’s life spent in caring for the children.A woman’marrying at the end of the nineteenth century would probably have been in her middle twenties,and would be likely to have seven or eight children,of whom four or five lived tiU they were five years old.By the time the youngest was fifteen,the mother would have been in her early fifties and would expect.to live a further twenty years,during which custom,opportunity and health made it unusual for her to get paid work.Today women marry younger and have fewer children.Usually a woman’s youngest child will be fifteen when she is forty-five years old and is likely to take paid work until retirement at sixty.Even while she has the care of children,her work is lightened by household appliances and convenience foods. This important change in woman’s life-pattern has only recendy begun to have its full effect on women"s economic position.Even a few years ago most girls left school at the first opportunity,and most of them took a full time job.However,when they married,they usually left work at once and never returned to it.Today the school leaving age is sixteen,many girls stay at school after that age,and though women tend to marry younger,more married women stay at work at least until shortly before their first child is born.Very many more afterwards retum to full or part-time work.Such changes have led to a new relationship in marriage,with the husband accepting a greater share of the duties and satisfactions of family life,aid with both husband and wife sharing more equally in providing the money,and running the home,according to the abilities and interests of each of them.<br>According to the passage,it is now quite usual for women to__________ .
