Termites are social insects like ants, living in well-organized colonies established and centered around a queen and her mate. The queen’s chief function is to lay eggs. Termites of a worker caste, white in color, tend the eggs and young and go forth to find food. Other termites form a soldier caste; they are white also but have larger heads than the workers. In the spring, young queen and king termites-brown or black in color--fly from the nest and enter the ground to mate and start new colonies.
The colonies are underground because the soil provides moisture the termites need to sustain life. A worker dining on a tasty door frame, for example, may make several trips below ground daily, both to bring food to the colony and to replenish its own moisture supply. If its retreat to earth is cut off, it will die. In brief, termites only go into wooden structures to eat. They can’t move in and set up housekeeping there unless they find a supply of wat

[单项选择]Passage Four
Like everyone else at eBay’s San Jose, Calif., campus, John Donahoe sits in a cubicle (隔间). Though this is one of the Internet company’s oldest commonplaces, the company’s 6-ft. 5-in. new CEO really does use the tiny space as his office.
Tough love is a very fitting description for the Chicago native’s eBay tenure so far. In the nine months since assuming the top job, the former Dartmouth basketball player, 48, has shown a penchant for shaking things up. In October he acquired three companies on the same day that he laid off 10% of eBay’s 16,000 workers worldwide.
Although you’d think that eBay’s flagship marketplace business, a site where people go to buy and sell stuff, would flourish in a downturn, it has stopped growing.

[填空题]Give three kinds of insects which like to group together.

[单项选择]Bats, tortoises, snakes, frogs, even insects like butterflies, hibernate more or less completely. Some, like the squirrels, sleep during coldest weather but are aroused by a warm spell. During hibernation, the temperature of an animal’s body drops drastically. Breathing and heart-beats almost cease.
Another instinctive method of avoiding intense cold is to escape by means of migration. Wild swans, seagulls, swallows and cuckoos are a few of the very many kinds of birds which fly thousands of miles, twice a year, to avoid cold. Many animals, especially those of the Arctic reindeer of Europe, move southward towards the forests when winter approaches. They return to the northern area when the warmth of spring begins to be sensed.
Arctic reindeers of Europe avoid the severe cold in winter by
A. hibernation.
B. migration.
C. staying in a" secret place".
D. growing thick fur.
