What is the difference between 'present perfect tense' and 'simple past tense'? Usages of 'present perfect tense' and 'simple past tense'.
The present perfect tense is used to indicate an event that started in the past and still continues or has a result now. The simple past tense is used to indicate an event that started and ended in the past. 

・I have lived in Germany for five years. (I still live in Germany.) 

・I lived in Germany for five years.&nbsp;(I no longer live in Germany.) 


・I washed the car, but now it's dirty again. 
・I have washed the car. It's clean now. 
・I met her at the party, but I have forgotten his name.
 Words that indicate a specific period of time, such as 'yesterday, last week, two days ago', are only used with the simple past tense. 


・I didn't see him yesterday.

・It was very cold last night.

・He arrived twenty minutes ago.

・When did you finish your homework?

・I lived in France&nbsp;when I was a child.

・What time did you have your dinner?
 With the expressions 'today, this morning, this week, this month, this year', the simple past tense is used when talking about a finished time period, and the present perfect tense is used when talking about an unfinished time period. 


・I haven't drunk coffee this morning. (The morning continues - I can still drink coffee.) 

・I didn't drink coffee this morning.&nbsp;(The morning is over - I can drink coffee in the afternoon.) 
 If 'before' is used with the present perfect tense, it emphasizes a past experience; and with the simple past tense, it emphasizes the past. 


&bull; I have read this book before.&nbsp;(Experience - emphasizes that I have read the book.) 

&bull; I read this book before.&nbsp;(Past - emphasizes that I read it before.) 
 The adverbs 'already, yet, just' are generally used with the present perfect tense. But in American English, especially in spoken language, the simple past tense is preferred. 


・He has already left. ・He already left. (American)

・I haven't finished yet. ・I didn't finish yet.&nbsp;(American)

・He has just arrived. ・He just arrived. (American)

The Indefinite Article 'A/An'

The possessive case is used to show possession. In English, possessive nouns are formed by using the ending 's or the preposition of. Typically 's is used with living beings, and of is used with inanimate beings. 
<h2>'s Usage </h2>
's is added to singular nouns.
・John's house 
・Mia's car 
・my friend's dog 
 's is added to plural nouns that do not end in -s. 
・children's toys 
・women's shoes 
 Plural nouns ending in -s are changed to s'. 
・students' books 
・my friends' bags 
 's is added to proper nouns ending in -s, but in classical literature s' is preferred. 
・James's car 
・Dickens' novels 
 To avoid repeating words, just a noun with&nbsp;'s (a possessive) can be used instead of a full noun phrase. 
・This isn't my pencil. - It's my friend's. (= It's my friend's <s>pencil</s>.) 
・Whose umbrella is this? - It's Tom's. (= It's Tom's <s>umbrella</s>.) 
 When talking about a person's home or workplace, the noun that comes after 's can be omitted from the sentence. 
・We're going to Mia's for dinner. (= Mia's home)
・I must go to the hairdresser's today. (= hairdresser's shop) 
 If two nouns are joined by the conjunction and, 's is added to the second noun. 
・Mia and Tom's children 
・Mr and Mrs Brown's house 
 Multiple nouns can be connected to each other with 's, forming compound possessives. 
・my friend's mother's car 
<h2>Possessive Case </h2>
's used for humans and animals. 
・Tom's house 
・the dog's tail 
・his uncle's car 
 's is used with time expressions. 
・today's newspaper 
・yesterday's homework 
・next week's meeting 
 's is used when referring to a process. 
・a day's journey 
・two hours' delay 
 A process can also be specified without 's, as in the example below. 
・We'll have a six-day holiday in France. ・We'll have six days' holiday in France.
 's and of can be used with names of institutions, organizations and groups. 
・the government's policy / the policy of the government 
・the committee's decision / the decision of the committee 
・the company's sales / the sales of the company 
・Germany's president / the president of Germany 
・the world's population / the population of the world 
 Of is generally used for inanimate beings. 
・the beauty of nature 
・the name of the movie 
・the cover of the book 
・the top of the mountain 
・the beginning of the year 
・the owner of the cafe
