（9分）阅读材料，回答问题。
材料一北方果农利用麦秸、稻草、玉米秆、杂草等有机物质，覆盖于树盘、树行（一行行果树）或全果园。覆盖厚度在15-20cm，一般连续覆盖3-4年为一个周期。每年将腐烂的物质埋入果园地，然后继续覆盖上述有机物质。利用自然生杂草和生草覆盖时，最好在夏季进行。
材料二下图为某区域年太阳日照时数及苹果产地分布图。下表为不同苹果产区与最适宜区的气候资料。

材料三 B所在地区是我国苹果主产区之一。目前，该区红富士苹果栽培面积约占苹果总面积的60%，早、中熟品种面积偏低，致使成熟期过于集中；商品化处理仍以简单的手工分级为主，大部分采用土窖贮藏；主要以家庭为单位生产，很难实现产、运、贮、销一体化。
（1）为什么利用自然生杂草和生草覆草最好选择在夏季？（2分）
（2）某课外活动小组的同学对种植苹果的区位选择在A地还是B地产生了争论。对此谈谈你的观点，并从自然条件角度说明理由。（4分）

阅读下面短文, 按任务写作的要求以约30个词概括文章的主要内容。
Teenagers’ secrets should be kept to themselves and no one else, their parents included, has the right to stick their nose into their private life.
As we know, teenagers are going through a special period of development both physically and psychologically（心理上). They are curious about and puzzled by the unexpected changes in their body and mind. What’s more, exposed to a world of adults, it is only too natural for them to begin following the example of adults’ behaviors in secret. Boys begin to smoke and girls begin to spend time doing their hair and care more about what to wear. Some even begin to date with a girlfriend or boyfriend without letting their parents know. They are doing all this in secret because they are still unsure whether it is right to do so and afraid that, if found out by their parent, they will get misunderstood and even punished. In fact, in many cases, parents can not deal with such matters well but hurt their children’s feelings badly, making children unwilling to communicate with them any more. When this happens, it terribly hurts feelings of the family as well.
Therefore, it sounds reasonable and acceptable that teenagers should keep their secrets to themselves instead of sharing them with their parents, who should give them the freedom in dealing with secrets.
