represent,代表,呈现;等于,是,如:
This contract represents 20% of the company's annual revenue. 这份合约相当于公司20%的年收入。
A significant portion of the cost is represented by regular visits by health care professionals.成本的很大一部分是医疗护理专业人员的定期拜访支出。
1. 反身代词多表强调,而本文并非在强调自己:John has chosen the one that is the most important to him. 这里只是在说对他重要,没必要扯到他自己上去.
用到反身代词的地方,例如: you can speak to yourself.... , he seems himself as..... , Roy, himself as a pianist...... ,
2. and letting似乎在描述另一件事,而“,letting”像是在对上文进行一种补充。
关于doing做伴随状语的逻辑主语问题:
伴随状语的主语要求是主句主语,但在表示某事的发生引起某个结果时,doing的逻辑主语可以是前面整个主句,而不是主句主语这一个名词。
如:Crime has recently decreased in our neighborhood, leading to a rise in property values.leading引导的东西就是犯罪减少的结果,leading的主语是前面整个句子,而不是crime这个东西。
整个句子=That crime has recently decreased in our neighborhood leads to a rise in property values.
V,春夏小群,秋冬大群。
结论:V这样是因为年轻V死亡率的季节性变化。
A,春夏季V包含最多的年轻V。
E,蛇在春夏季活跃,吃V。
CR:春夏小群说明年轻V死得多,而不是活得多。活得多的话春夏就是大群了。
