Following the nuclear at the Fukushima (福岛) nuclear power station in Japan, Germany has decided to abandon the use of nuclear energy sooner than it had planned.

Germany was planning to cut its use of nuclear power slowly over 25 years. But now, the government has speeded up its program. Germany’s government has said that seven of its 17 nuclear reactors (反应堆) will stop working for three months for safety checks.

Nuclear power has been very unpopular in Germany since the Chernobyl (切尔诺贝利) nuclear reactor disaster in Ukraine (乌克兰) in 1986. Since then, the country has been working on developing new resources of energy.

The plan to give up nuclear power will cost the country at least 150 billion euros (1.4 trillion yuan)) in investment. Experts say this will likely lead to a rise in electricity prices.

Some experts think Germany is setting a good example for countries such as the US to follow. Germany now gets 23 percent of its energy from nuclear power –about as much as the US.

However, France, which relies on nuclear energy for more than 70 percent of its power, shows no sign of changing its policy.

小题1:

We can most probably read the article _______. 

A.in a newspaper

B.in a pamphlet(小册子)

C.in an advertisement

D.in a textbook小题2:

The most appropriate heading for this article is _______.

A.Germany to develop its new resources of energy

B.Nuclear power no longer popular in Germany

C.Germany to have safety checks for some nuclear reactors

D.Germany to end its nuclear energy program小题3:

According to the article, all of the following statements are true EXCEPT______.

A.In both the US and Germany, approximately a quarter of their energy are from nuclear power now.

B.The explosion of some Fukushima nuclear reactors has quickened Germany’s pace to abandon nuclear energy.

C.France, which relies on nuclear energy for more than 70 percent of its power, will follow Germany and cut its use of it at any cost.

D.The Chernobyl nuclear disaster seemingly cast a huge shadow over the Germans, making them increasingly suspicious of the safety of nuclear energy.

单项选择题 A1/A2型题
实验题

(18分)(1)用如图(甲)所示的实验装置来验证牛顿第二定律,为消除摩擦力的影响,实验前必须平衡摩擦力.

①某同学平衡摩擦力时是这样操作的:将小车静止地放在水平长木板上,把木板不带滑轮的一端慢慢垫高,如图(乙),直到小车由静止开始沿木板向下滑动为止.请问这位同学的操作是否正确?如果不正确,应当如何进行?答:                              

②如果这位同学先如①中的操作,然后不断改变对小车的拉力F,他得到M(小车质量)保持不变情况下的a—F图线是下图中的        (填选项代号的字母).

③若交流电的频率为,某同学在正确操作下获得的一条纸带,A、B、C、D、E每两点之间还有4个点没有标出.写出用s1、s2、s3、s4以及f来表示小车加速度的表达式:a=                

(2)某同学利用如图甲所示的实验装置测量重力加速度。

①请指出该同学在实验操作中存在的两处错误:

a                           ;        b                           

②该同学经正确操作得到如图乙所示的纸带,取连续的六个点,测得h1、h2、h3、h4、h5.若打点的周期为T,则打E点时速度为vE=     ;若分别计算出各计数点对应的速度数值,并在坐标系中画出v2与h的关系图线,如图丙所示,则重力加速度 g=     m/s2
