Rita's efforts caught the attention of her science teacher, Mr. Thompson. He turned her work into a class project, and Rita became the class expert (专家) on ants. Her hard work helped the whole class learn about ant behavior and habitats. They even built a small ant farm in the classroom to observe the ant closely.
Gradually, Rita's classmates became more and more interested in the ant project. They started asking her questions and observing the ant's behavior themselves. Rita organized a presentation where she shared her findings with the whole school during the science fair.
At the end of the year, Rita's class was recognized as the best of the year. Rita was as well praised for her hard work and how she turned a small task into something big. Rita learned that every task, no matter how small, could make a big difference. She also learned that sometimes the most unexpected things can lead to great success.
29.What was Rita's job this term
A.To look after plants. B.To raise an ant.
C.To become an expert. D.To build an ant farm.

4、哈三中2025-2026学年度上学期高二9月月考数学答案
【知识点】测定空气中的氧气含量;氧气与碳、磷、硫、铁等物质的反应现象;电解水实验;化学方程式的书写与配平
【解析】【解答】(1)实验①中铁丝剧烈燃烧,火星四射,放出大量的热,为防止高温熔融物溅落炸裂瓶底,会在瓶中放少量的水或铺一层细纱;
(2)水是电的弱导体,在水中加入硫酸钠能增强导电性,使反应更快;实验②中发生的反应为水通电分解生成氢气和氧气,方程式为:2H2O2H2↑+O2↑;
(3)实验③打开止水夹前红磷燃烧产生大量白烟,放出热量;
(4)A、反应开始时,红磷燃烧放热,温度升高,气体膨胀,压强增大,故A正确;
B、打开止水夹后,水进入集气瓶,随着水的进入,压强增大,因此A点后气压增大是由于水倒吸入集气瓶,故B正确;
C、红磷燃烧消耗氧气,所以氧气浓度一直在减小,为曲线Z;红磷燃烧放热,温度先升高后减小,最终变为初始值,为曲线Y;红磷燃烧放热,开始压强增大,后逐渐减小,打开打开止水夹前低于初始值,打开止水夹后,水进入集气瓶,压强恢复到初始值,为曲线X,故C错误。
(3)①__氧气、铜__ ___
②—COO-、ROH__ __取代反应(或水解反应)__(各1分)
(4)____。(1分)
(5)__13(2分)______(1分)。
