Soap operas from South Korea have been popular in China for more than twenty years now. So it is not the first time for the soap operas made in China to feel less popular. But this time, they are facing more difficulties, for The Heirs and My Love from the Star really made a full success, which even attracted some top officials.

A senior official said he sometimes watched soap operas from South

Korea, as well as House of Cards , an American opera about politics . These operas made both in South Korea and in America have a lot of lovers in China.

Many people agree that China’s soap operas can’t be much loved by most Chinese, because they are not as interesting and exciting as those operas from South Korea and America, such as My Love from the Star, a Korean love story between a time traveling professor and a famous movie star.

However，Korean shows not only provide soap operas but also some programmings . Dad, Where Are We Going? is not an original Chinese show. We learned it from South Korea although not many in China realize that fact.

Actually, China has a closer culture with South Korea. Shows from this neighbor seem to do better with their exciting stories on the Cinderella theme . Yet they have created many popular shows whose sto ries tell there’s no difference between men and women even though in their country men are certain to play a more important role.

（1）When might soap operas from South Korea become popular in China?

A . 1991.

B . 1971.

C . 2010.

D . 2001.

（2）Most people in China like watching shows made in _____.

A . Europe

B . China

C . South Korea

D . Japan

（3）The operas made in China are not as popular as those in South Korea or America, because _____.

A . senior officials don’t allow us to watch them

C . Chinese people are more interested in politics

D . they were only made twenty years ago

（4）According to the passage, we can know Dad, Where Are We Going? is _____.

A . more popular than My Love From the Star

B . loved by a lot of Koreans

C . about the love between a professor and a star

八年级下学期期中测试卷(B)

八年级下学期期中测试卷（B）一、选择题（每小题4分，共40分） 1.下列关于力的说法中正确的是（） A.三要素都相同的两个力一定是平衡力。 B.物体受非平衡力作用时，运动状态一定发生改变 C.游泳运动员只受到水向前的力，他对水不施力 D.“蜘蛛人”攀爬高层建筑时，使他上升的力是他对自己的拉力。【分析】A、三要素都相同的力，说明它们的方向都相同，这就不可能是平衡力。C、这一说法违背了力的相互性。D、决定物体运动不是自身对外的施力，而是受力。“蜘蛛人”能攀爬高层建筑，是他对高层建筑施力后，高层建筑反作用力使他上升，而不是他对自己的拉力。【答案】B 2.人造地球卫星绕地球做圆周运动，在地球对它的吸引力突然消失的瞬间(不计其他阻力)它将() A.继续做圆周运动 B.做匀速直线运动 C.竖直向下运动 D.静止在空中【分析】卫星受到的地球吸引力突然消失的瞬间，可把卫星看成是一个不受力的物体，其运动规律遵循牛顿第一定律，由题意可知，卫星原来在运动，外力消失的瞬间它将沿原来的运动方向做匀速直线运动。【答案】B 3.如图所示的四幅图中，力的作用使物体发生明显形变的是( ) 【分析】A选项中人用力使弓变弯，说明了力使物体发生形变；B选项中磁铁的排斥力使磁体由静止变为运动，C选项中带电体将小纸屑吸起，D选项中运动员用头将足球顶入球门，这三个事例说明力可以改变物体的运动状态。【答案】A 4.放在水平桌上的书，受到的一对平衡力是( ) A.书对桌面的压力与桌子的重力 B.书的重力与桌面给书的支持力 C.书的重力与书对桌面的压力 D.书对桌面的压力和桌面对书的支持力【分析】解本题的依据是二力平衡条件，即两个作用在同一个物体上的力，大小相等、方向相反，且作用在同一直线上．而平衡力与相互作用力的区别主要在于相互作用力是分别作用在两个不同的物体上．对照选项判断，A、C项既不是一对平衡力，又不是一对相互作用力；D项是一对相互作用力；B选项是一对平衡力，是本题的答案．【答案】B 5.关于牛顿第一定律，下列说法正确的是〔〕 A. 该定律通过小车斜面的实验直接得到 B. 该定律不能用实验证明，只是一种猜想 C. 该定律可以用实验来证明，因为它是力学的一个基本定律 D. 该定律是在可靠的事实基础上，通过科学推理概括出来的，虽然不能用实验来证明，但
