Can you do the math:What is one hundred times four,divided by the square root of a hundred? How can you work it out quickly?

The answer is forty.Years ago,three scientists at Texas Instruments,Jerry Merryman,James Van Tassel and Jack Kilby,invented the handheld electronic calculator.Their first device could add,subtract,multiply and divide and it was small and easy to take.

Yet after forty years,calculators in the classroom still add up to the same old debate Generally calculators are considered to be useful——especially with more complex math.Some math teachers at every level support the use of calculators and students are even permitted to use them when they take college entrance tests.But it is also thought that young students should know basic calculation before they begin using them.

Some education experts think calculators are used too much. Children,they say,learn to depend on these electronic brains instead of their own.Calculators may not only give students answers to questions they do not really understand,they may also keep them from discovering ideas for themselves.

Other experts,though,say calculators have helped make mathematics more understandable to more students.They say calculators give students more time to understand and solve problems,and to develop a better sense of what numbers mean.That way,the reasoning goes,they can feel better about their abilities.

1.Which of the following calculation agrees with the question raised in the 1st paragraph?

A.             B.             C.           D.

2.Three scientists at Texas Instruments invented                 

A.the first electronic calculator              B.the calculator handle

C.the portable electronic calculator        D.the first calculator

3.We can infer from the passage that         in the past.

A.math teachers supported using calculators everywhere.

B.students were not allowed to use calculator in tests.

C.using calculators in classrooms was under argument.

D.young students had to know how to use calculators.

4.According to experts,calculators benefit students in many ways EXCEPT             

A.providing them with answers to the questions

B.stopping them discovering ideas for themselves

C.making mathematics more understandable

       D.developing a better feeling of their abilities

 

 

22、Among the crowd of Olympian gods the most famous one was Apollo. He was the son of Zeus and Letto. According to Greek mythology, Letto was driven by Hera, Zeus' wife, from land to land and at last Poseidon took pity on her and brought the island of Delos out of water for her to live on. There she gave birth to the twins, Apollo and Artemis.

Wearing a purple robe, Apollo usually sat in his bright eastern palace early in the morning and made ready to start his daily journey across the sky. During the day he drove his carriage of gold and ivory(象牙), and brought light, life and love m the great world below. In the afternoon he came to the end of his journey in the far western sea and got on his golden boat to return to his eastern home.

Apollo was the god of music and poetry. He could bring about all feelings, which are expressed in his noble songs. With his gold musical instrument and the sweet accents of his godlike voice he led the choir of the muses(音乐女神们) at Olympus. The pleasant music was so exciting that stones marched into their places of their own will in musical time when he helped Poseidon build up the walls of Troy(特洛伊城). On one occasion, invited to a contest by the human musician Marsyas, he won and then flayed(剥……的皮) him to death for his pride. On another occasion, he lost at a musical contest and turned the ears of the judge, King Midas, into those of an ass(驴子).

Apollo stood for youthful and manly beauty. His golden hair, stately manner and air all combined to make him the admiration of the world. A beautiful girl, by the name of Clytle, was so fond of his beauty and glory that from dawn to dusk she knelt on the ground, her hands outstretched towards the sun god, and her eyes looked at his golden wheeled carriage racing across the blue sky. Though her love was not returned, she had never changed her mind about
