谁能帮我拟订一份详细的暑假学习计划。我高一要升高二了。

B

B“ 抽出时间复习数学、英语和物理 ”与语文学习计划无关；A“ 谨遵吾师之教诲 ”过于文言化，不符合实用文体的语言规范；D“ 养成书写规范、端正、整洁 ”缺少宾语的中心语“习惯”。

1. Nowadays school and the whole society pay more and more attention to be thankful. This Thanksgiving education surround us. The atmosphere for us better person to lay a solid foundation. 2.Be thankful for us. Everyone is very important, because now, the children are at the center of the family, and their hearts, not only yourself to others. Let them learn "Thanksgiving", in fact, is that they learn to respect others. Learn to be grateful to let children with equal view of each life, respect each ordinary ordinary labor and more respect yourself. Only the people know how to be grateful, his life will be less of borrowing. 3. So I need to consciously doing. Secondly, Thanksgiving education as the carrier to activities from activities, and return to reality experience gratitude, I'm going to start in life, from every practice of gratitude. Strive to be the state's contribution to have the youth.

解题思路：（1）熟悉一些重要气体的性质，二氧化碳溶于水，不适合用排水法收集；
（2）根据氧气能助燃，可以用带火星的木条进行检验；二氧化碳可以使澄清石灰水变浑浊．

（1）二氧化碳溶于水，不能用排水法收集．
故答案为：B；鳔内的CO₂能溶于水，收集到的CO₂体积比实际小；
（2）氧气具有助燃的特性，燃着的木条放入瓶中木条可以继续燃烧；二氧化碳可以使澄清石灰水变浑浊．
故答案为：
实验目的实验方法可能观察到的实验现象及结论
比较鳔内和空气中氧气含量用燃着的木条分别伸入盛有鳔内气体和空气的两个集气瓶中木条在盛有鳔内气体燃烧比空气中旺（不旺），说明鳔内O₂含量比空气大（小）
比较鳔内和空气中二氧化碳含量分别往盛有鳔内气体和空气的两个集气瓶中倒入澄清石灰水盛空气的集气瓶中的澄清石灰水不变浑浊，盛有鳔内气体的集气瓶中的澄清石灰水不变浑
浊（变浑浊），说明鳔里气体CO₂含量与空气接近或较低（较高）．

点评：
本题考点： 实验探究物质的组成成分以及含量；常见气体的检验与除杂方法．

考点点评： 做有关气体方面的题时，一定要想到气体的性质．在检验气体时要注意检验气体的先后顺序，防止出现差错．

解题思路：（1）在此题中要掌握二力平衡条件的应用，要测量摩擦力的大小，需拉动测力计做匀速直线运动，此时拉力大小与摩擦力大小相等．弹簧测力计读数时，要看清分度值和指针的位置．
（2）滑动摩擦力大小跟压力大小和接触面粗糙程度有关．在压力相同时，接触面粗糙程度不同，滑动摩擦力大小不同；在接触面粗糙程度相同时，压力不同，滑动摩擦力大小不同．

（3）要测滑动摩擦力，需水平拉动木块做匀速直线运动，此时拉力与摩擦力是一对平衡力，大小相等．读出弹簧测力计示数F₃，研究滑动摩擦力的大小跟接触面粗糙程度的关系．把研究的结果综合起来：滑动摩擦力的大小跟物体间接触表面的粗糙程度以及压力的大小有关．在压力一定的情况下，接触表面越粗糙，滑动摩擦力越大；在接触面粗糙程度相同的情况下，压力越大，滑动摩擦力越大．
故答案为：水平；粗糙；大；大

点评：
本题考点： 探究摩擦力的大小与什么因素有关的实验．

考点点评： 掌握滑动摩擦力大小跟压力大小和接触面粗糙程度的关系，利用控制变量法探究滑动摩擦力大小的关系．
我们不但能根据实验现象总结实验结论，而且能根据需要设计实验．

参考： Ladies and gentlemen, Welcome to our city.Nangjing,which is the capital of Jiangsu Province lies in the southest of China.It has a population of about 5 million. The city has a history of more than 2,400 years and itwas the capital of ten periads.It‘s really a very beautiful city.It has a lot of places of intenest,such as the Xuanwu Lake and the Jiming Temple.There are also many modern factories and tall buildings here.The Changjiang River Bridge in Nangjing is world famous,too.
