解析試題分析：考查時態(tài)：主句是過去時的時候，賓語從句一般是相應的過去時，但如果賓語從句是客觀真理的時候，主句即使是過去時，從句也應該是一般現(xiàn)在時。句意：他說光比聲音的速度快。選B。
考點：考查時態(tài)
點評：英語中的時態(tài)主要由動詞的形式?jīng)Q定，因此在學習英語時態(tài)時，要注意分析動詞形式及具體語境，想象在那個特定的時間動作所發(fā)生的背景，這題容易錯當成過去時，但是看清句意后，會發(fā)現(xiàn)這是客觀真理，還是一般現(xiàn)在時。

"Once you go down this path, it' s something you continually struggle with, which is exactly why the law is so important．The new law is not about me, it' s about the next generation of kids coming up．What we don ' t want is kids going down that path," he said．

NANJING, June 13,2009 (Xinhua) – China will see the longest total solar eclipse (日食) in 500 years on July 22, a scientist said Saturday.

The most important time of the total eclipse was expected to

begin from 9:00 a.m. to 9:38 a. m. (Beijing Time), said Wang

Sichao, a research fellow with the Nanjing – based Purple

Mountain Observatory under the Chinese Academy of Sciences.

“The total eclipse will l ast up to six minutes, which is the longest

one that can be seen in China in almost 500 years from 1814 to 2309,” Wang said.

He said viewers in parts of eleven provinces in China's southwestern, central-southern and eastern areas, such as Tibet, Hunan and Jiangsu, will be able to witness the total solar eclipse, while in most parts of Shanghai, viewers can see the spectacular phenomenon. For viewers in other provinces, including Beijing, they can observe a partial eclipse, he said.

A solar eclipse occurs when the moon is caught between the sun and the earth while each of them moves along their fixed orbits. In a total solar eclipse, the sun, the moon and the earth are directly aligned as the sun swings into the cone of shadow cast by the moon.

Wang said the next total solar eclipse that can be seen in China will fall on March 20 th, 2034.     "But it can only be seen remote provinces, such as Tibet and Qinghai. It cannot not be compared with the upcoming one -- in terms of duration and number of cities that can see the eclipse," he added. The last total solar eclipse visible in China took place on Aug. 1 last year. It was observed in northwest China and lasted two minutes in Yiwu County of northwestern Xinjiang Uygur Autonomous Region, the best place to see the phenomenon.

72．According to the report, the total eclipse on July the 22 nd will last         .

A．over a month                                                    B．a(chǎn)bout 38 minutes

C．a(chǎn)bout 6 minutes                                              D．less than 30 minutes

73．Viewers can possibly witness the total solar eclipse in            .

A．Liaoning                   B．Sichuan                    C．Beijing                      D．Xinjiang

74．When a total solar eclipse happens,          .

A．the moon goes into the shadow cast by the sun

B．the earth stays between the sun and the moon

C．the sun temporarily moves into the moon’s orbit

D．the sun is in a line with the moon and the earth

75．Which is the best title for this report?           .

A．China to witness longest total solar eclipse in 500 years

B．The most important total solar eclipse will favor China

C．The beginning time of the total solar eclipse is expected

D．China has been the best place to witness the solar eclipse
