下面是广州、上海、北京、哈尔滨四个城市气温曲线与降水量逐月分配图,分析回答:(8分)

(1)哈尔滨和广州两地1月平均气温相差30℃左右,这说明冬季我国南北气温有什么特点?

                                                             ;

哈尔滨和广州两地7月平均气温相差5℃左右,这说明在夏季我国南北气温有什么特点?

                                                            。

(2)四个城市各月柱状图表明,我国东部地区的降水量由             向            逐渐减少,降水的季节分配都集中在__________季。

(3)由上述可以总结出,我国由北向南雨季的时间越来越      ,年降水量越来越      

(4)我国东部地区,雨季开始和结束的迟早主要是由         季风的进退决定的。

答案

(1)南北温差大 ,越往北气温越低;南北普遍高温

(2)南,北,夏

(3)长、多

(4)夏

题目分析:

(1)根据图中气温曲线图得知,哈尔滨和广州两地1月平均气温相差30℃左右,这是因为冬季太阳直射南半球,受纬度的影响,冬季南北气温差异大。根据图中气温曲线图得知,夏季哈尔滨和广州两地7月平均气温相差5℃左右,气温差别不大,夏季除青藏高原外,全国普遍高温。

(2)影响我国年降水量的季风主要是夏季来自太平洋的东南季风和来自印度洋的西南季风,随着夏季风影响的大小,年降水量从东南沿海向西北内陆递减。

(3)根据图中降水量柱状图得知,我国的降水主要集中在5月到9月,这是由于夏季风带来的降水重要集中在这个时间,锋面雨带每年5月在我国的东南沿海登陆,6月推移到江南一带,7、8月份推移到我国的北方,9月份又重新退回东南沿海,10月退回海上。根据锋面雨带的运行规律,全国各地雨季来临时间是不同的。南方锋面雨带来得早,退得晚,雨季就长;北方锋面雨带来的晚,退的早,雨季就短。我国由北向南雨季的时间越来越长,年降水量越来越多。

(4)我国的降水主要集中在5月到9月,这是由于夏季风带来的降水重要集中在这个时间.影响我国的夏季风主要是来自太平洋 东南季风和来自印度洋的西南季风。我国东部地区,雨季开始和结束的迟早主要是由夏季风的进退决定的。我国夏季的主要降雨类型是锋面雨,全国各地雨季来临时间是不同的。南方锋面雨带来得早,退得晚,雨季就长;北方锋面雨带来的晚,退的早,雨季就短。我国由北向南雨季的时间越来越长,年降水量越来越多。

A child may lean against a doorpost with his or her arms folded. To the onlooker, it may look like a benign posture—however, there may be a victimized child who understands that this is the bully’s "shorthand" code of conveying the message: "Hand me your lunch as you walk by me, or else."

Bullying may be expressed in many forms. Boys are generally targeted more than girls. Boys tend to use physical aggression when they bully .by hitting, kicking, and fighting. Girls, on the other hand, more often use exclusionary techniques to bully—a form of aggression often referred to as relational aggression. Girls often start rumors, form cliques to keep certain people out, and ignore other children in attempts to show dominance over another child.

Many children who are victimized fit into one of two types: the passive victim, and the provocative victim. While people often feel bad about passive victims, provocative victims often elicit less compassion from others. Sometimes it appears that the provocative victim has "brought on" his or her own fate—but does any child deserve to be the target of repeated physical or verbal aggression Why might so-called provocative victims actively participate in being the target of bullying: For example, are their provocative gestures simply a clumsy way of attempting to interact with others One feels compassion for the inhibited child because he is reserved; a social misfortune in our society, but an aggressive child is given none of this.

The dynamics of the bully/victim relationship need to be understood in a larger context (Pepler, Craig & O’Connell, 1999). It is not only the bully and the victim that is involved in a system of interaction: The bullying context includes multiple levels of the child’s social environment. The bully may enlist the help of "henchmen" (those who assist the bully, but often do not have the initiative or leadership to initiate bullying). Also, bystanders (whether actively encouraging the bullying act or passively standing by) play a role in maintaining the pattern of bullying. Even the students who habitually flee the site of a bullying act play a role in maintaining the bully/victim interaction.

In handling the situation, it is important not to focus only on the one or two students that are directly involved, but on the playground and school as a whole. Studies have shown that in order to break down the stability of peer bullying you must initiate change on many levels: Not only in teaching the bullied child how to assert himself or herself and to deflect attacks, but also to raise awareness about the problem of bullying and encourage the school community at large to take a united stance against bullying.

According to the author, what kind of perspective should we have for school bullying().

A.Dynamic.

B.Comprehensive.

C.Individual.

D.Optimistic.
