1、吉林高中2025~2026学年度上学期高三联合考试(26-T-287C)历史试题


This year, it was hard to tell whether my prize or the one chosen by my 14-year-old brother, Jason, was the winner.Unfortunately we forgot to weigh them before taking out their insides, but I was determined to prove my point.All of us were hard at work at the kitchen table, with my mom filming the annual event.I'm unsure now why I thought forcing my head inside the pumpkin would settle the matter, but it seemed to make perfect sense at the time.
With the pumpkin resting on the table, hole uppermost, I bent over and pressed my head against the opening.At first I got jammed just above my eyes and then, as I went on with my task, unwilling to quit, my nose briefly prevented entry.Finally I managed to put my whole head into it, like a cork (软木塞) forced into a bottle.I was able to straighten up with the huge pumpkin resting on my shoulders.
My excitement was short-lived.The pumpkin was heavy.“I'm going to set it down, now,” I said, and with Jason helping to support its weight, I bent back over the table to give it somewhere to rest.It was only when I tried to remove my head that I realized getting out was going to be less straightforward than getting in.When I pulled hard, my nose got in the way.I got into a panic as I pressed firmly against the table and moved my head around trying to find the right angle, but it was no use.“I can't get it out!” I shouted, my voice sounding unnaturally loud in the enclosed space.

17.如图所示是硫在氧气中燃烧的实验。燃烧停止后,取出燃烧匙,用毛玻璃片盖紧集气瓶,振荡,悬空倒置,发现毛玻璃片不脱落。
(1)硫在氧气中燃烧的文字表达式为________________________。
(2)水的作用是 _____________________________________。
(3)毛玻璃片不脱落时,大气压强    (填“大于”“小于”或“等于”)瓶内气体压强。
18.阅读下面科普短文,结合所学知识回答相关问题。
稀有气体包括氦、氖、氩、氪、氙和氡6种气体,约占空气体积的0.94%。常温常压下,稀有气体都是无色无味,微溶于水,且熔点和沸点都很低。由于稀有气体元素原子子的最外层电子排布结构都是稳定结构,所以它们的化学性质非常稳定,但在一定条件下,氙气(Xe)可与氟气(F2)发生反应,生成四氟化氙(XeF4)。工业上,制取稀有气体是通过将液体空气蒸馏(即利用物质的沸点不同进行分离),得到稀有气体的混合物,再用活性炭低温吸附法,将稀有气体分离开来。在焊接精密零件时,常用氩气作保护气。氦气是除了氢气外的最轻气体,通常用氦气代替氢气应用在飞艇中,不会着火和发生爆炸。利用稀有气体通电时发出色彩绚丽的光芒,可以制成霓虹灯。
根据上述文章内容,回答下列问题。
