QUIZ I 1. There is a 1-in-17 chance of drawing two successive hearts (红桃) in this manner. 2. The varieties of nonferrous (有色的) metals are nearly four times what they were. 3. There are races (种，属) between animals large and small. 4. Leprosy does not affect most animals the way it does humans. 5. Aiken’s machine was limited in speed by its use of relays rather than electronic devices. 6. Familiar to all with but the slightest exposure to scientific literature, this model shows the atom as a miniature solar system. 7. The absence of atmosphere in space will allow the space telescope to show scientists light sources as far as 14-billion light years away, some seven times farther out than those visible to the biggest ground-based optical telescope

变压器是由绕在铁芯上的两个或多个线圈构成 的一种装置。 这本书如果使用得当,对读者是很有帮助的。 若已知时间和速度,我们就能求出距离来。 a transformer is a device consisting of two or more coils wound on the iron core This book, properly used, is of great help to the reader Given time and speed, we can find out distance
