Ques: We're trying to decide where to go on our vacation this summer. We usually go to the Lake Arrowhead for a few weeks, but we'd like to go somewhere else this year. We're tired of doing the same thing summer after summer. Some friends of ours suggested that we go to Hawaii. That would be wonderful! I'm sure we'd enjoy a trip like that, but of course _ . In the first place, it would be rather expensive, and in the second place, there wouldn't be enough time. If we're lucky enough to save some money between now and next summer, and if I'm lucky enough to get four weeks of vacation instead of two weeks, maybe we can go to Hawaii next year. As a matter of fact, if we wanted to plan a trip like that, it might be advisable to stay home this summer and not go any place. That's one way we could begin to save some money for next year's trip. Also, if we were to stay here, I could offer to work instead of taking two weeks off; then maybe my boss would suggest that I be given four weeks' vacation next summer instead of two weeks. The author _ to spend their vacation this year. A) is going to Hawaii B) will go to Lake Arrowhead C) has decided to go nowhere D) hasn't decided where to go

Greenwich is on the River, five miles from the middle of London, and its history is two thousand years old. The first English people were fishermen there, and they named the place Greenwich, meaning "green village". Later the English kings and queens lived at Greenwich in their beautiful places. The name of the earliest palace was Placentia. Its windows were made of glass--the first in England. But trouble was coming to Greenwich. In 1649, a war started in England and for eleven years there was no king. The men who had worked for him at Placentia decided to live in the place themselves. They sold all its beautiful things, and bought small pieces of the palace garden with money. Finally, the war ended and King Charles II came back. But Placentia was falling down. So King Charles built a new and bigger palace, which is now open to the public. At this time, Charles was worried about losing so many of its ships at sea because their sailors did not know how to tell exactly where they were. So in 1675, Charles made John Flamsteed, the first astronomer in England, try to find the answer. Flamsteed worked in a new building on the high ground in Greenwich Park. From it with a telescope which he made himself, Flamsteed could look all round the sky. And he did, night after night, for twenty years. Carrying on Flamsteed's work a hundred years later, an astronomer called Harrison finally made a clock which told the time at sea, and helped sailors to know where they were.You can see Harrison's clock, still working, in Greenwich's museum of the sea. Because of Flamsteed's work, every country in the world now tells its time by Greenwich time. Placentia was _ palace in Greenwich. A) the biggest B) smallest C) the earliest D) the latest
