`1.` Compare the functions of V-ing in English with their expressions in Vietnamese.
 - In English, the V-ing form serves various functions such as denoting continuous actions, forming gerunds, and as adjectives. For instance, "running" can imply an ongoing action, a hobby, or describe a noun (a running track).
 - Vietnamese expressions differ as they often use specific words to indicate ongoing actions or states. For example, the word "đang" is used to denote an action in progress, similar to the English V-ing.
`2.` Describe the similarities and differences between the verb "GO" in English with "ÐI" in Vietnamese
  - Both "GO" and "ÐI" express the basic action of movement from one place to another.
  - In English, "GO" can be used with various prepositions and adverbs to form phrasal verbs with different meanings, such as "go out," "go over," or "go through."
  - In Vietnamese, "ÐI" is often followed by destination markers or verbs to provide context, but it does not form phrasal verbs as in English.
`3.`Compare the compound sentences in English with those in Vietnamese.
  - English compound sentences typically connect two independent clauses with a conjunction like "and," "but," or "or."
  - Vietnamese compound sentences also connect clauses, but the relationship between them can be indicated through particles and conjunctions specific to the language's structure.
`4.` Compare the formation of Adverbs in English with that in Vietnamese.
  - English adverbs of manner are commonly formed by adding "-ly" to adjectives (e.g., "quick" becomes "quickly").
  - Vietnamese adverbs can be formed by adding words before or after the verb they modify, without a specific suffix like "-ly."
`5.` Compare the usage of adverbs of frequency in English with that in Vietnamese
  - In English, adverbs of frequency such as "always," "usually," "often," "sometimes," and "never" are placed before the main verb or after the verb "to be."
  - In Vietnamese, similar adverbs are used ("luôn," "thường," "đôi khi"), and they typically precede the main verb. The placement can vary slightly depending on the sentence structure and emphasis desired.
