The significant words found on    1    old key,"If I rest,I rust",would be an excellent motto for those    2    are affected by the slightest bit of idleness.Even the most industrious might adopt it with advantage to serve    3    a reminder that,if one allows his talents to rest, like the iron in the unused key,they will soon show signs of rust and,finally, cannot do the work    4     (require) of them.

Those who would achieve the targets reached and kept by great men must keep their minds active by constant use,so that they may    5     (lock) the doors of knowledge, the gate that guard the     6     (enter)to different professions,to science,art,literature,agriculture-every field of human effort.

Industry keeps bright the key that opens the treasury of achievement.If Hugh Miller,after    7    （work) all day,had devoted his evenings to rest and entertainment,he would never    8     (become) a famous geologist.The    9     (celebrate) mathematician,Edmund Stone,would never have published a mathematical dictionary, never have found the key to science of mathematics,     10    he had given his spare moments to idleness.

Book of the Week: Tomorrow’s People by Paul Morland

If you haven’t “been paying attention”, the message of this book is “going to come as a shock”, said David Aaronovitch in The Times.     1     argues that the “big demographic problem” of the future isn’t     2     there will be “too many people” on the planet, but that there will soon be “too few”. The world’s population is growing now, and in this “pithy and well-structured book”, Paul Morland, a lecturer at Birkbeck College in London, predicts it will go on doing so for a while yet,     3    (peak) at around 11 billion later this century. But that trend, he argues, is deceptive, because it depends on rapid growth in a few places,     4    sub-Saharan Africa. Meanwhile, across much of the rest of the planet, fertility rates     5    (fall) so fast that those dying are not being replaced. “Most of the West reproduces below or well below replacement rate,     6     does China.” Morland’s prediction is that the world’s population will fall significantly, with a profound effect on “social dynamics”.

    7     the heart of Morland’s analysis is a process known as the “demographic transition”, said Sarah Harper in Literary Review. This holds that as societies develop economically, life expectancy increases-leading to a population surge. But then, as such societies become     8    (prosperous), women start having fewer children and their populations age and decline. The demographic transition is particularly advanced in Japan, a country with 79,000 centenarians, said Colin Freeman in The Daily Telegraph. Italy, Bulgaria and Russia are also shrinking fast. By contrast, Nigeria’s population     9    (expect) to double to 400 million by 2050. Tomorrow’s People is a well-argued work that provides a “concise chronicle of our global breeding habits”, and which is “illuminating on     10     the ebbs and flows (消长) of population can influence history”.

As we all know, reading a book can make you filled with curiosity and patience, and have a sense of     1     (responsible). It can open the door to an excellent new world of magic and discovery, which is why people all around the world love to read. Read and then relax     2     (you). Annually many famous prizes     3     (award) to the creative individuals. One such prize goes to the best new work of children’s fiction.

The award dates back to 1921, when Frederic Melcher advised the American Library Association set up     4     annual award for the best new children’s book. Everyone agreed, and     5     (eventual), they were determined to name the award after John Newbery, an 18th-century English publisher,     6     had made great efforts to improve children’s literature. The winning book is selected by a committee, ranging from year     7     year, and the process of     8     (choose) a winner takes an entire year. Sometimes, the committee will appoint honor books, which are books that might not have won the award, but are still considered to be very     9     (impress).

Therefore, if you are at the bookstore, take a look at the children’s section and you are likely     10     (select) one you are fond of.
