[判断题]长弧灭弧主要是拉长电弧和冷却电弧使之熄灭。（）-我要搜题网

[单项选择]Oxford is a very old town on the River Thames, about 60 miles from London. Unlike modern university towns, where you usually find the university on the edge of the town, or on its own campus (校园), Oxford’s center is the university; and all around the crossroads at the very heart of Oxford, Carfax, there are grey stone colleges and other university buildings. In the center you can also find interesting old restaurants. There are a lot of churches, and a few really large and interesting buildings, such as the Ashmolean Museum, the "round" library, the Bodleian and Radcliffe Camera. Like all English towns, there are parks, and one" The Parks" is the home of university cricket(板球) in the summer months. As you leave the center and go towards the edge of Oxford you can see industrial areas in one direction; and in another, beautiful suburbs(郊区). There is, in fact, quite a lot of industry in Oxford.
Visitors to Oxford will find that ______.
A. the university is also the town center
B. one of the crossroads is called Carfax
C. the university is on the edge of the town
D. most buildings are modern and interesting

[单项选择]Are some people born clever, and others born stupid Or is intelligence developed by our environment and our experience Strangely enough, the answer to these questions is yes. To some extent our intelligence is given us at birth, and no amount of special education can make a genius out of a child born with low intelligence. On the other hand, a child who lives in a boring environment will develop his intelligence less than one who lives in rich and varied surroundings. Thus the limits of a person’s intelligence are fixed at birth, but whether or not he reaches those limits will depend on his environment. This view, now held by most experts, can be supported in a number of ways.
It is easy to show that intelligence is to some extent something we are born with. The closer the blood relationship between two people, the closer they are likely to be in intelligence. Thus if we take two unrelated people at random from the population, it is likely that their degree of intelligence wil
A. at birth
B. through education
C. both at birth and through education
D. neither at birth nor through education
