The first coins to appear in the Western world were issued by the Indians and the Ionian Greeks in the eighth century B. C. These coins, which were made of electrum, a natural combination of gold and silver, were irregular in weight and quality. The pure gold and silver coins with related values which appeared during the reign of Croesus (560 -546 B. C. ) provide the first un doubted evidence of standard coinage by state authority. The coins were not perfectly shaped, however, for they were struck with a hand wielded hammer.

In Italy the neurologist Cesare Lomrose discovered a blind girl who could "see" with the tip of her nose and the lobe of her left ear. In 1956 a blind schoolboy in Scotland was taught to differentiate between colored lights and learned to pick out bright objects several feet away.

[单项选择]TEXT B I know when the snow melts and the first robins (知更鸟) come to call, when the laughter of children returns to the parks and playgrounds, something wonderful is about to happen. Spring cleaning. I’ll admit spring cleaning is a difficult notion for modern .families to grasp. Today’s busy families hardly have time to load the dishwasher, much less clean the doormat. Asking the family to spend the weekend collecting winter dog piles from the melting snow in the backyard is like announcing there will be no more Wi-Fi. It interrupts the natural order. "Honey, what say we spend the weekend beating the rugs, sorting through the boxes in the basement and painting our bedroom a nice lemony yellow " I say. "Can we at least wait until the NBA matches are over " my husband answers. But I tell my family, spring cleaning can’t wait. The temperature has risen just enough to melt snow but not enough for Little League practice to start. Some flowers are peeking out of the thawing ground, but
A. Because there will be more activities when it gets warmer.
B. Because the air is fresher and the breeze is lighter.
C. Because the whole family is full of energy at spring time.
D. Because the snow is melting and the ground is thawing.
