D

For Chinese, it’s a time for dragon boat racing and Zongzi(粽子). But across the Yellow Sea, South Korea, wrestling(摔跤)and swing play are the highlights. However, both events go by the same name---the Dragon Boat Festival---which falls on May 5 of the lunar calendar.

One festival, two cultures: does one nation have the right to call its own? It has been reported that South Korea will apply to the United Nations Educational, Social and Cultural Organization(UNESCO联合国教科文组织)to make the celebration its cultural heritage(文化遗产). If successful, people from other countries may see the Dragon Festival as a Korean creation.

As the birthplace of the yearly event more than 2,000 years ago, China is not happy with the situation. “It would be a shame if another country successfully made a traditional Chinese festival part of its own cultural heritage ahead of China,”said Zhou Heping, deputy culture minister. The Ministry of Culture is even thinking of making its own application to UNESCO, covering all traditional Chinese festivals, including the Dragon Boat event.

Over the years, the Dragon Boat Festival has spread throughout the world. In Japan and Viet Nam, as well as South Korea, the festival has mixed with and become part of local culture.

With this in mind, some experts say that it is meaningless to argue about which country the festival belongs to. “No one can deny that it came from China,”said Long Haiqing , an expert from Hunan Province. “But if all the countries involved can protect culture heritage together, they will all benefit.”

56. The underlined word “highlights”can be probably replaced by “     ”.

A. most exciting events     B. highest lights on the building

C. brightest lights at night    D. most famous festivals

57. It can be inferred that South Korea ______.

A. has proclaimed(宣布)the Dragon Boat Festival as a part of its cultural heritage

B. has the exactly same Dragon Boat Festival as China

C. has no idea that China has such a festival

D. is paying more attention to its cultural heritage than China

58. China is not happy with the situation because .

A. it created the festival

B. it is also making an application

C. South Korea has no right to call the festival its own

D. UNESCO may approve(批准)South Korea’s application

59. If South Korea’s application to UNESCO is successful, _____.

A. China will also make its own application to UNESCO

B. it will be meaningless to celebrate the Dragon Boat Festival

C. people from other parts of the world will think South Korea created the festival

D. the Dragon Boat Festival will become part of local culture

60. The author would probably support____ .

A. a move by South Korea to cancel its application

B. China getting UNESCO’s approval of the festival first

C. the opinion of Zhou Helping

D. China paying more attention to its cultural heritage

问答题

(1)“探究动能定理”的实验装置如图所示,当小车在两条橡皮筋作用下弹出时,橡皮筋对小车做的功记为W0.当用4条、6条、8条…完全相同的橡皮筋并在一起进行第2次、第3次、第4次…实验时,橡皮筋对小车做的功记为2W0、3W0、4W0…,每次实验中由静止弹出的小车获得的最大速度可由打点计时器所打的纸带测出.关于该实验,下列说法正确的是

A.某同学在一次实验中,得到一条记录纸带.纸带上打出的点,两端密、中间疏.出现这种情况的原因,可能是没有使木板倾斜或倾角太小.

B.当小车速度达到最大时,橡皮筋处于伸长状态,小车在两个铁钉的连线处

C.应选择纸带上点距均匀的一段计算小车的最大速度

D.应选择纸带上第一点到最后一点的一段计算小车的最大速度.

(2)某兴趣小组在做“探究做功和物体速度变化关系”的实验前,提出了以下几种猜想:①W∝v,②W∝v2,③W∝

v
.他们的实验装置如图甲所示,PQ为一块倾斜放置的木板,在Q处固定一个速度传感器(用来测量物体每次通过Q点的速度).在刚开始实验时,有位同学提出,不需要测出物体质量,只要测出物体初始位置到速度传感器的距离和读出速度传感器的读数就行了,大家经过讨论采纳了该同学的建议.

①请你简要说明为什么不需要测出物体的质量?

②让小球分别从不同高度无初速释放,测出物体初始位置到速度传感器的距离L1、L2、L3、L4…,读出小球每次通过Q点的速度v1、v2、v3、v4、…,并绘制了如图乙所示的L-v图象.若为了更直观地看出L和v的变化关系,他们下一步应怎么做?
