1.Many things have been done and great progress has been made in the greenization of our cities in recent years. Many trees have been planted and much care has been taken of the planted trees. But, in spite of all this, greenization in the cities in China is far from satisfactory compared with cities in other countries in the world. For example, the green space for every people in Shanghai is only 2 square meters while that of the people in London exceeds 20 square meters.最近几年,在绿化我们的城市方面许多事情都已经完成，并取得了很大进展的,许多树木已种植和许多树木已经妥善照顾。但是，即使如此，在城市绿化中和世界其他国家的城市比,中国还远远不能令人。例如，在上海每人拥有2平方的绿色空间而在伦敦每人超过20平方米。
2We can benefit much from the greenization of our cities. First, trees absorb carbon dioxide which is harmful, but produce oxygen which is essential to human beings. Secondly, with trees all around, our cities will look more beautiful. Thirdly, trees can improve the climate of the cities, making it neither too hot in summer nor too cold in winter.
我们可以获益的绿化我们的城市。首先，树木吸收有害的二氧化碳，产生人所必须的氧气。其次,周围环绕着树木，我们的城市就会更美丽。第三，树木可以改善城市的气候，使其夏天不会太热,冬天不会太冷
3 Since we can get so much benefit from making our cities greener, we should spare no effort to do so. We should plant even more trees and take even better care of them while they are growing. Besides, we should not cut down trees any more. In a word, we should do everything to add to the greenization of our cities.
既然我们可以从城市绿化中得到这么多好处，我们就应该不遗余力地这样做。我们应该更加树木植物，并 更好地照顾他们。此外，我们不应该砍树了。总之，我们应该尽一切努力增加绿化我们的城市。
这个相对简单不翻译了：）
Nowadays, people living in the city often find the environment not agreeable. There has little green land between the urban areas. We can’t see the more grass, flowers and trees except in the parks. And we can feel the color of the city is gray.
People are crying for more green in the city and it is really advantageous to have more grass, flowers and trees in the urban area. First, green plants can reduce the pollution. It is a difficult problem in the city. People couldn’t figure out the effective measures to cope with the situation. If having more green, the environment in the city will become more comfortable. Second, more grass, flowers and trees can make our city beautiful. Green plants can bring us a refreshed feeling.
Therefore, in city planning people should think more about grass, flowers and trees. We can call on more citizens to join the activity and provide more lands for green plants. I believe if we do like that, our city will become more beautiful.
CET4 lasted fifteen years, the evaluation in good ones and in bad ones.大学英语四级考试历时十五年,评价褒贬不一
in my opinion,disadvatages are more than advantages.CET4 is designed to detect non-English-speaking college students learning English two years later, after the attainment of <College English syllabus> on the basis of the requirements phase.在我看来，弊大于利。全国大学英语四级考试的设计目的是检测非英语专业大学生经过二年英语学习后是否达到<大学英语教学大纲>对基础阶段的要求.
CET4 is large-scale examination, more students, consider for reliability and validity and operational , its title with an objective-based questions.四级考试规模大,考生多,出于信度、效度和操作性考虑,其题型以客观题为主
from the test perspective, CET4 has got a great success, promote the implementation of the outline, and renowned throughout the country, welcomed by students.从测试角度讲,四级考试的确取得了巨大成功,有力促进了大纲的实施,并使之蜚声全国,深受大学生的欢迎. However, CET4 had a tremendous negative impact for College English teaching , it cann't fully reflect the true English language ability of students.然而,四级考试也对大学英语教学产生了巨大的负面影响,并不能全面反映学生真实的英语能力.
希望对你 有帮助~
