2026年3月襄阳市高三统一调研测试语文试题


Why should people care? Because we need animals. And because once they are gone, there will never be any more. Animals are more than just beautiful and interesting. They are more than just a source of food. Every animal has its place in the balance of nature. Destroying one kind of animal can create many problems. For example, when farmers killed large numbers of hawks, the farmers’ stores of corn and grain were destroyed by rats and mice. Why? Because hawks eat rats and mice. With no hawks to keep down their numbers, the rats and mice increased quickly.
Luckily, some people are working to help save the animals. Some groups raise money to let people know about the problem. And they try to get the governments to pass laws protecting animals in danger. Quite a few countries have passed laws. These laws forbid the killing of any animals or plants on the danger list. Slowly, the number of some animals in danger is growing.
8. Animals are important to us mainly because ________.
A. they give us a source of food B. they are beautiful and lovely
C. they keep the balance of nature D. they give us a lot of pleasure
9. What has happened to the animals on the earth?
A. Only a few animals have disappeared.

1、2026年3月襄阳市高三统一调研测试 答案


24.【答案】
【解析】(1)小明连接好如图甲所示的电路,该电路有一处故障是:电阻与电流表并联了,将电流表应与电阻串联,电压表与电阻并联,如下图所示:

(2)滑动变阻器的滑片应置于阻值最大处,即图中最左端;滑动变阻器有保护电路和控制定值电阻两端电压不变的作用;
(3)闭合开关后,电流表有示数,说明电路通路,而电压表无示数说明与电压表并联的电路短路,故此时电路的故障可能是定值电阻短路;
(4)实验中,当把10Ω的电阻换成20Ω的电阻后,根据分压原理,电阻两端的电压变大,研究电流与电阻关系时要控制电压不变,根据串联电路电压的规律,要增大滑动变阻器两端的电压,由分压原理,要增大滑动变阻器电阻阻值,故应把滑动变阻器滑片向左滑动;
(5)4节新干电池电压为6V,电阻两端的电压始终保持UV=4V,根据串联电路电压的规律,变阻器分得的电压:U滑=U-UV=6V-4V=2V,变阻器分得的电压为电压表示数的0.5倍,根据分压原理,当接入50Ω电阻时,变阻器连入电路中的电阻为:R滑=0.5×50Ω=25Ω,故为了完成整个实验,应该选取最大阻值至少25Ω的滑动变阻器,而现有变阻器的最大电阻太小;控制的电阻电压不变,变阻器分得的电压过小,即电源电压太大了;故当小明将50Ω定值电阻接入电路时,无论怎样调节滑动变阻器的滑片,都无法使定值电阻两端电压为4V,则原因可能是所选滑动变阻器的最大阻值太小或电源电压过大;
