学习会计学中V-ing形式的用法规则及时态变化说明

V-ing form is a common grammatical structure in English that is used to indicate ongoing actions or states. It can be divided into two main types: present participle and gerund, each with its own distinct usage. The formation of V-ing form is relatively simple, involving the addition of -ing to the base form of the verb. However, there are some rules to keep in mind when forming V-ing form. Firstly, for regular verbs, the rule is to simply add -ing to the base form of the verb. For example, "work" becomes "working" and "study" becomes "studying". Secondly, when a verb ends in a silent 'e', the 'e' is typically dropped before adding -ing. For instance, "like" changes to "liking" and "make" changes to "making". Thirdly, for verbs that end in a stressed closed syllable with only one consonant at the end, the consonant is doubled before adding -ing. Examples include "set" becoming "setting" and "run" becoming "running". Lastly, verbs that end in "ie" change to "y" before adding -ing, such as "die" becoming "dying". V-ing form can be used in various tenses and voices, including the simple, progressive, and perfect tenses, as well as the active and passive voices. This flexibility allows for a wide range of expressions and meanings to be conveyed through V-ing form. Overall, mastering the use of V-ing form is essential for developing fluency and accuracy in English communication.
