题目:

几千年前,在非洲湿热的原始森林里,土著居民用着火堆,跟随各种复杂节奏自由而热烈地边舞遍唱。这种歌声,也许在某些“文明人”眼里算不上音乐。然而,这样的声音却是最原始的,是在恶劣环境里顽强的本能所发出的生命之音,如果说布鲁斯音乐是很多音乐的根源,那么,上面所说的便是这个根源的根源。这段文字是一篇文章的引言,文章接下来最应该讲述的是( )

A.人类本能在原始音乐中的表现

B.布鲁斯音乐与土著音乐的源流关系

C.土著音乐产生的历史背景

D.自然环境与音乐风格的关系

“Now I just don’t believe that.” Surely all of us, at some point, have watched a movie and thought: It’s simply badly researched, or, the makers must think we’re fools.

If movies were completely scientifically accurate, they’d probably be as interesting as a Physics 101 lecture. In real life, there are no explosions in space, gas usually doesn’t explode from a lit cigarette, and Bruce Willis / Jackie Chan / Will Smith would most likely be in a coma(昏迷) after getting kicked in the head.

Recently, the British newspaper The Daily Telegraph ran a humorous piece on unconvincing tech moments from some top movies. Let’s see what they are all about.

Telegraph writer Tom Chivers’ first example is from the end-of-the-world movie Independence Day, in which a character comes up with a virus capable of destroying Windows, the computer system the alien(外星人的) spacecraft uses. “It’s a good thing they didn’t have Norton antivirus,” jokes Chivers.

It’s just one case of a movie that takes a lot of license with its science. Another one Chivers mentions is from Star Wars, where glowing beams of light traveling through space look very impressive. The problem is that in space there are no air particles(颗粒) for the light to reflect off. In reality, they’d not be seen, which wouldn’t look so cool on the big screen.

Chivers’ second piece of Star Wars nonsense is the sound the fighters make in the movies: “ the bellow(咆哮) of an elephant mixed with a car driving on a wet road”. But sound needs a medium to travel through, like air. In space, there wouldn’t actually be any sound at all.

Few people would deny that the mind-bending Matrix films make for great viewing, but for Chivers, the science in the movies is a little silly.

And finally: as Chivers points out, DAN is not replaceable. But this bit of elementary genetics passed the makers of the 2002 Bond film Die another Day by. In the film the villain(坏人) has “gene therapy” to change his appearance and his DNA, which is completely impossible.

小题1:What does the text mainly deal with?

A.Plots of some famous movies.

B.Characters in space movies.

C.Popularity of space movies.

D.Mistakes made in some movies.小题2:From the first two paragraphs we can know that some movie makers ____.

A.went against general knowledge of science

B.didn’t pay attention to the viewers’ real demand

C.overestimated viewers’ appreciation of movies.

D.didn’t try their best to improve the quality of the movies.小题3:What does the underlined word “they” in Paragraph 3 refer to?

A.The newspapers.

B.Unconvincing tech moments

C.Some top movies.

D.Heroes in the movies.小题4:We can learn from Paragraph 7 that ____.

A.most people like Matrix films

B.the truth of Matrix films remains in doubt

C.few people think Matrix films silly

D.Chivers thinks science is unacceptable

背景材料:

在做喷泉实验时.通常的做法是在干燥的圆底烧瓶里充满氨气,用带有玻璃管和滴管(滴管里预先吸入水)的塞子塞紧瓶口,倒置烧瓶,使玻璃管插入盛有水的烧杯(预先在水里滴入少量酚酞溶液),轻轻挤压滴管,使少量水进入烧瓶。下面是某老师对喷泉实验的创新设计:

如下图所示,用5 mL的注射器来代替胶头滴管,实验前将注射器注满水,实验时,推动注射器柱塞。

问题:

(1)此实验的反应原理是什么?

(2)指出原装置存在的缺陷和实验改装之后的优点。
