小题1:_______ is the latest film according to (根据) the article.
A.Ice Age 3B.Pirates of the Caribbean 4
C.Sherlock HolmesD.Toy Story 3
小题2: Which of the following is RIGHT according to the article?
A.Johny Depp is the director of Pirates of the Caribbean 4.
B.Film fans don’t think Sherlock Holmes is a good film.
C.The two cartoons are produced by the same film studio.
D.Ice Age 3 is a cartoon suitable for different age groups.
小题3: From the article, we know ______ is a cruel character.
A.SidB.Sherlock Holmes
C.LotsoD.Jack Sparrow
答案

小题1:B

小题2:D

小题3:C

1.B  找到每部电影的时间。Pirates of the Caribbean 4是May 20th, 2011; Sherlock Holmes是Dec. 25th, 2009 ;Toy Story 3是June 18th, 2010 Ice Age 3是July 1st, 2009,故最新的是B。

2.D 由Ice Age 3 is a whole new adventure that everyone at any age can enjoy可知其适合每一个年龄阶段,故D对。根据Johnny Depp, a famous actor, works together with a new director, Rob Marshall可知导演是Rob Marshall,故A错;由This one you certainly don’t want to miss可知这是一部很好的电影,故B错;Toy Story 3由Walter Disney Pictures制作,而Ice Age 3由Dream Works Pictures制作,故C错。

3.C 根据cruel bear named Lotso可知C正确。

单项选择题 A1/A2型题
填空题

利用如图所示电路测量一量程为300mV的电压表的内阻RV,RV约为300Ω.

实验步骤如下:

①按电路图正确连接好电路,把滑动变阻器R的滑片P滑到a端,闭合开关S2,并将电阻箱R0的阻值调到较大;

②闭合开关S1,调节滑动变阻器滑片的位置,使电压表的指针指到满刻度;

③保持开关S1闭合和滑动变阻器滑片P的位置不变,断开开关S2,调整电阻箱R0的阻值大小,使电压表的指针指到满刻度的一半;读出此时电阻箱R0的阻值,即为电压表内阻RV的测量值.实验所提供的器材除待测电压表、电阻箱(最大阻值999.9Ω)、电池(电动势约1.5V,内阻可忽略不计)、导线和开关之外,还有如下可供选择的实

A.滑动变阻器(最大阻值150Ω);

B.滑动变阻器(最大阻值10Ω);

C.定值电阻(阻值约20Ω);

D.定值电阻(阻值约200Ω).

根据以上设计的实验方法,回答下列问题:

(1)对于上述测量方法,从实验原理分析可知,在测量无误的情况下,实际测出的电压

表内阻的测量值R______真实值RV(填“大于”、“小于”或“等于”)

(2)为了使测量比较精确,从可供选择的实验器材中,滑动变阻器R应选用______,定值电阻R'应选用______(填字母代号).

(3)在其它元件不变的情况下,为使测量更准确,可换用一电动势更______的电池(内阻可忽略)(填“大”或“小”)
