24.在“驗證凸透鏡成像規律”的實驗中,應調節光源、凸透鏡和光屏的中心大致在 (5) 。現有焦距分別為50厘米、30厘米、25厘米和15厘米的凸透鏡各一塊,為了得到完整的規律,應選用焦距為 (6) 厘米的凸透鏡,此時在圖14中的蠟燭和透鏡位置保持不變,則可在 (7) 厘米刻度線的 (8) 側(選填“左”或“右”)找到所成的像。
25.某小組同學做“測定小燈泡功率”的實驗。所有實驗器材均完好,共有四個滑動變阻器待用,分別是A:“10Ω 1A”、B:“20Ω 2A”、C:“50Ω 2A”和D:“100Ω 2A”,已知小燈的額定電壓為3.8伏。
(1)該組同學首先選取變阻器C進行實驗,他們按照正確的方法進行實驗操作,觀察到閉合電鍵后,電流表的示數為0.1安,電壓表的示數為1伏,而小燈好像沒有發光。該組同學實驗室所選的電源電壓為 (9) 伏。
(2)該組同學接著移動變阻器的滑片,觀察到當滑片在變阻器最大阻值的1/4位置附近滑動時,小燈接近正常發光,但是此時移動變阻器的滑片,電壓表的示數很難比較精確地達到3.8伏。于是該組同學換了個變阻器進行實驗,他們閉合電鍵后,發現電壓表的示數略大于額定電壓,則他們選取的是變阻器 (10) (選填“A”、“B”或“D”)。
(3)該組同學最后通過討論、選取了合適的變阻器,并完成了實驗。他們發現當滑片在中點時小燈正常發光,此時電流表的示數如圖15所示,則小燈的額定電流為 (11) 安,小燈的額定功率為 (12) 瓦。
26. 小偉和小趙等同學做實驗探究盛有液體的容器底部受到液體壓強大小與哪些因素有關,如圖16(a)所示,在三個不同底面積的圓柱形容器中分別注入質量相等的水,利用儀器測得容器底部受到水的壓強,并將相關實驗數據記錄在表一中;接著用酒精重復上述實驗操作,并將數據記錄在表二中;隨后,他們又在如圖16(b)所示的三個不同底面積的口大底小容器中注入等質量的水,重復上述實驗,數據記錄在表三中.通過分析發現液體對容器底的壓強與容器的形狀、液體質量是無關的.下面請同學們根據他們記錄的數據繼續分析.(已知ρ酒精=0.8×103千克/米3)
圖16
(1)分析比較實驗序號 (13) 有關數據,可得出的初步結論是:同種液體,當液體深度相同時,液體對容器底部的壓強與容器底部面積大小無關。
(2)分析比較實驗序號1、2、3(或4、5、6或7、8、9)可知:
(14) 。
(3)為了得出液體容器底部受到液體壓強大小與 (15) 的關系,分析比較實驗序號1與4(或2與5;3與6;4與7;5與8;6與9)可知:
(16) 。
(4)該小組同學根據表格中的數據計算了液體對容器底的壓力并與液體的重力進行比較.歸納得出結論:
(a) 分析比較表一或表二中的數據及相關條件,可初步得出
(17) ;
(b)分析比較表三中的數據及相關條件,可初步得出
(18) 。

A mother and her daughter lived in a village. Every night, the mother would lock the door with three locks, because she was afraid that a thief might come in. As time went by, the daughter became tired of her boring life there, and dreamed to go to the city to see the outside world. One day, she left home without telling her mother. “Forget me, Mum.” She thought.
But the outside world wasn’t as good as she thought .Eight years later, she came back home with a tired body and mind.
When she got home, it was dark. She knocked at the door, but nobody answered. Surprisingly, she found the door was unlocked. She came in and saw her mother was lying in her bed, sleeping. Tears ran down her face. Hearing the cry of her daughter, the mother woke up. They hugged and cried. Later, the daughter asked, “Mum, why didn’t you lock the door ” “I was afraid you wouldn’t be able to get in when you came back” Mum answered.

Dear Lily,
My hometown is very small. Only a few hundred people live here. It has a river with an old stone bridge across it. There is a church and a school. They are next to each other. People usually go to church on Sunday. There are three teachers and thirty students in the school. On Main Street there is a hotel, a supermarket, a gas station, a bakery, a butcher’s shop and a book store.
We don’t have a hospital or a police station, but we have a doctor and a police officer. They live on opposite side of the river.
We don’t have a movie theater, but we can rent videos at the supermarket. If we want to go to a movie, we have to go to the next town. It is a 30-minute bus drive away. The bus stop is outside my house. I usually go to the movies with my mum every Saturday.
Best wishes and please write soon.

VII.
Nowadays many students say they are too busy with their study and they don’t have time to help their parents with the housework. I don’t think they are true, that’s all excuses.
In my opinion, doing some housework such as washing our own clothes and making the bed is our own responsibility. It can also make us independent. We can’t depend on others all our life. Sharing the housework is helpful for us to set up good relationship with our parents. I think trying to do some housework can keep us healthy and strong, some hard housework can be regarded as a kind of physical exercise. And we can take care of ourselves better when we grow up.
On weekdays, I often help my parents clean my bed rooms every morning and wash dishes after supper. At weekends, washing clothes and mopping the floor is my duty. And I also help my parents carry something heavy from the supermarket.
As the saying goes’ One can't make a big success without being self reliant’, so I think that students should often share the housework in our daily life.2012學年奉賢區調研測試
