【題目】某小組研究小燈泡電功率,小燈泡額定電壓為2.5V,電源電壓恒定不變,有規格為“10Ω
2A”和“20Ω 2A”的滑動變阻器各一個.
(1)如圖甲所示,選用“10Ω 2A”規格的滑動變阻器進行實驗.連接電路時,需將滑動變阻器的滑片P置于 (填“A或“B)端,其目的是 .
(2)接著用開關迅速試觸,燈泡發光,電壓表示數如圖乙,此時燈泡兩端電壓為 V.為了使燈泡正常發光,接下來的操作是: .
(3)實驗中收集信息如上表.分析表格中信息可得,①小燈泡額定功率為 W;②在電路安全范圍內,小燈泡兩端實際電壓越大,消耗的電功率 ,燈泡越亮.

【題目】Einstein often received invitations to explain his theories at different universities. On these trips, his driver was always the same man called Hans. Hans often said to him. “It is a pleasure to drive a talent like you, Dr Einstein.”
One evening, on their way to a university, Einstein said, “I’m so tired. I wish I could refuse to give my lecture(講座) tonight, Hans, but I don’t want to let my audience down.”
“I know what to do,” said Hans. “I can give the lecture for you. You can trust me. I’ve listened to your lecture so many times that I’ve learnt it by heart. No one knows you at this university, so they won’t find out.”
So, they changed places. At the university, Hans was guided to the front of the hall. Einstein took a seat, listened to Hans give his lecture without difficulty, and joined in the applause (掌聲) at the end.
However, before Hans left, a man shouted, “I’d like to ask you a question.” He then asked a difficult question and Hans had no idea what he was talking about.
Einstein turned pale. “Oh no! ,” he thought. “Now we’re in trouble.” But Hans just laughed and said, “That’s such an easy question that even my driver can answer it. Hans, please…”
Einstein stood up and answered the question perfectly.
They left the university, with Einstein driving. A little later, Hans offered to drive. “No, ” laughed Einstein. “It’s a pleasure to drive a talent like you, Hans.”

【2】Just as the mind map, the story can be divided into five parts: opening, rising action, turning point, falling action and ending. Which do you think is the turning point of it?
A. Einstein answered the question perfectly.
B. A man asked a difficult question.
C. Hans offered to give a lecture for Einstein.
D. Hans asked Einstein to answer the question.
【3】What would be the best title for this story?

【題目】閱讀甲乙丙三圖,回答下列問題
甲 我國年降水量分布圖
乙 中國主要山脈分布圖圖 丙 我國主要畜牧業區和種植業區
(1)讀甲圖,概括歸納我國降水空間分布的總體趨勢: ,
這種趨勢的形成原因是: 。
(2)對比甲圖和丙圖,畜牧業區與種植業區的界線大致與 毫米年等降水量線一致。這說明我國農業區的分布受 (氣溫或降水)的影響很大。
