Summer, fall and winter may have their fans, but spring is the most lovely of the four seasons. Here are some scientific 41 why spring is great.
Spring marks the end of the 42 winter. In many places, the temperature in this season is about 15 to 21℃. People feel the most comfortable at a temperature of around 22℃, so the coming of spring means people can finally 43 their heavy winter clothes.
From the Spring Equinox (春分), days 44 become longer and nights become shorter, which means people have more daylight hours. Research has 45 that more hours of sun play an important role in helping people relax. The longer the sun is up during the day, the 46 people will get.
Besides, many animals move south during the winter in China. Then they move back north 47 temperature rises. For northern areas, there’s no better 48 of spring than birdsong (鸟鸣) outside the window. It means that throughout the spring, people can expect to see lots of birds. And seeing more birds can make people 49 .
Across the seasons, research has found that taking walks in spring 50 people’s heart rate (心率) and makes them more relaxed. Spending 30 minutes outside in spring will put people in a cheerful mood.

1、[天一大联考]河南省2025-2026学年高三3月联考(HN202603)英语答案

【解析】【解答】（1）根据核反应方程，反应前氢核的质量数总和为4，电荷数总和为4×1。反应后两个正电子的质量数总和为2×0=0，电荷数总和为2×1=2。设X的质量数为A，电荷数为Z，则有A+0=4，Z+2=4，解得A=4，Z=2，的质量数为4，电荷数为2，故选B。
（2）复色光的频率~，当光的频率大于金属板的极限频率时，可发生光电效应，对比可知可发生光电效应的钠、钾、铷，故选CDE。
（3）电子绕氢原子核做匀速圆周运动，库仑力提供向心力，整理得
电子动量大小是
（4）氢原子从高能级向低能级跃迁时会放出光子，光子的能量等于两个能级的能量差。氢原子能级公式为，光子的能量
根据巴耳末-里德伯公式，又因为，可得
其中n是跃迁前的能级，k是跃迁后的能级。氢原子从n=4跃迁到n=2，n=4，k=2，根据可得，且是从高能级向低能级跃迁，放出光子，D正确。故选D。
