Câu hỏi:

Last week I made the mistake of visiting the village where I grew up. It was a small, friendly community with two farms and a number of old cottages round the village green. I realized very quickly that although in many ways it appears unchanged, in reality hardly anything is the same. All the pretty cottages are there, of course, and both the picturesque farmhouses. But none of the inhabitants are country people. All of them are commuters, who leave early every morning for the nearby town. Neither of the farmhouses is attached to a farm these days; the land has been sold and is managed by somebody in an office somewhere who has little interest in the village itself. There are a few new houses, but they have no local character; you can see the same style anywhere in the country. The whole of the village, in fact, has been tidied up so much that it has become nothing more than just another suburb. 1. When the writer revisited his village, he quickly realized that _____________. A. the village changed a lot in appearance B. everything has almost changed C. all the pretty cottages as well as the farmhouses have been built D. the residents of the village are all commuters 2. Neither of the farmhouses ________________. A. has a connection with a farm B. has been sold C. is attached to the farmers. D. is managed by the commuters 3. The word “managed” in the line 8 can be best replaced by ______________. A. controlled B. spent C. used D. taken 4. According to the writer, __________________. A. the village now has no local character B. all the new houses are the same style C. the village is tidier than it used to D. the village has become nothing but a suburb 5. Which of the following is NOT MENTIONED in the passage? A. The writer has visited the village several times before. B. The writer revisited his village last week. C. In fact, the village has changed much. D. The village nowadays has become another suburb.
