164 形式
现在进行时是由助动词be+现在分词（动词原形+ing）;
165 拼写
A 动词以单一的e字母结尾时,去掉e再加ing：
have,having
age,dye,和singe除外：
动词以ee结尾时,直接加ing：
agree,agreeing
see,seeing
B 单音节动词中只有一个元音字母并以单一辅音字母结尾时,则先双写该辅音字母再加ing：
run,running
pre'fer,preferring
单一元音字母后的结尾字母l总要双写：
signal,signalling
travel,travelling
在美国英语中,这种情况下l不双写.
以y结尾的动词可以直接加ing,该词的拼写不受任何影响：
164 Form
Present tense consists auxiliary "Be" and present participle (Verb+ing)
165 Spelling
A.For verbs which end up with a single letter "e"
---Add "ing" at the end of them instead of "e"(except"age","dye"and"singe")
For verbs which end up with double "e"
---Add "ing" at the end of them directly
B.For single syllable verbs which contain only one vowel and end up with a single consonant--
Double write that consonant and add "ing" at the end of them
The ending letter which is behind a single vowel should always be double written.
In American English,you can put on "ing" directly at the end of the verbs which end up with "y" .The spelling doesn't change.
还有ie结尾的变成y呀.
