We all know who Benjamin Franklin was. He was a very famous American statesman. He was also the first man to discover electricity. Franklin liked to study and to learn about new things. One day he heard from a friend that something black in colour holds the heat better than something white in colour. Franklin wanted to find out if this was true or not.

There was snow on the ground at the time. So he put two large pieces of cloth over the snow. One piece of cloth was black in colour, the other piece was white. Then he waited until the sun began to shine. After several hours he looked under the pieces of cloth and saw that the snow under the black cloth melted much faster than the snow under the white cloth. This proved to him that the black cloth held the heat better than the white cloth.

Soon after this, people began to wear white hats and white clothes during the summer because they were cooler.

根據(jù)短文內(nèi)容判斷正（T）誤（F）：

1.Benjamin Franklin was only a scientist.

2. One day a friend of his told him something about the relation(關(guān)系) between colour and heat.

3. Something black in colour holds heat better than something white in colour.

4.This story happened in summer.

5. People wear white clothes in summer because they know it is cooler.

 

【答案】

1.F

2.T

3.T

4.F

5.T

【解析】

1.由“He was a very famous American statesman”，可以看出，他不僅是個科學(xué)家,還是個政治家。

2.從文章的第一段可知，是一個朋友告訴富蘭克林黑色比白色吸熱。

3.從第二段弗蘭克林的實驗結(jié)論可以看出，本句是正確的。

4.弗蘭克林的實驗是在雪地里進行的，所以應(yīng)該是冬天，而不是夏天。

閱讀理解

　　Languages keeps evolving(進化、發(fā)展), and English is no exception．It is a language that embraces(欣然接受)new words that may be cool today but gone tomorrow．

　　There are, however, some words and phrases that have stood the test of time．OK, which has become the international standard for expressing agreement, is a good example．

　　But why is this rather odd(奇怪的)expression so popular and so useful when we could use any number of other words to say the same thing?

　　Writing in The Times, Allen Metcalf, author of OK：The Improbable Story of America’s Greatest Word, writes：“What OK provided that the others did not was neutrality(中性), a way to express agreement without having to offer an opinion．”

　　For example, if someone asks you “Shall we go for a walk after lunch?” you can simply respond “OK”．There you go－no extra opinions．Just straight, plain old OK．

　　So just where did this rather curious expression come from? The origins of OK have been widely disputed(辯論，爭論)．Some people have guessed that OK was the name of a person or a product．

　　Speakers of many different languages have had their say on this question, keen to claim the term as their own．

　　Writing an article for London’s Metro newspaper, Metcalf states：‘O and K are present in every language of the world, as expressions that can be abbreviated(縮寫)OK．” For example：French－“O qu-oui”, “yes indeed”; German－“Ohne Korrektur”,“ without correction needed”; and in Latin or Greek, “Olla kalla”, “all good”．

　　But, does it sound a little too informal with this popular little expression?

　　Apparently not．

　　In a speech where he stated that his election(當(dāng)選)would not be a radical(激進的)result to all problems, President Obama said：“…even though I am president…, AI-Qaida is still a threat(威脅)and that we cannot pretend somehow that because Barack Hussein Obama got elected as president, suddenly everything’s going to be OK,” he said．

　　So, there you go, straight from the president．It’s OK to say OK, and thanks to the expression’s widespread usage across the world, you can be understood anywhere．

(1)

Using the example of Obama, the author wants to show that _________．

[　　]

A．

there is still a long way to go to defeat Al-Qaida

B．

Obama likes to use OK when he speaks

C．

OK is widely used even on formal occasions

D．

the use of OK is encouraged in formal speech

(2)

According to Allen Metcalf, OK differs from other terms to express agreement, which of the following opinions is true?

[　　]

A．

It is easiest way to say．

B．

It doesn’t need emotion．

C．

It is the most commonly used．

D．

It doesn’t use in the formal speech．

(3)

What is the best title for the passage?

[　　]

A．

Why OK is OK everywhere?

B．

It’s OK to say OK in the world．

C．

Where did OK come from?

D．

Everything is going to be OK．
