Simple Present Tense

I sing
How do we make the Simple Present Tense?
subject + auxiliary verb + main verb
do base

There are three important exceptions:

1. For positive sentences, we do not normally use the auxiliary.
2. For the 3rd person singular (he, she, it), we add s to the main verb or es to the auxiliary.
3. For the verb to be, we do not use an auxiliary, even for questions and negatives.

Look at these examples with the main verb like:
subject auxiliary verb main verb
 
+ I, you, we, they like coffee.
He, she, it likes coffee.
- I, you, we, they do not like coffee.
He, she, it does not like coffee.
? Do I, you, we, they like coffee?
Does he, she, it like coffee?

Look at these examples with the main verb be. Notice that there is no auxiliary:
subject main verb
 
+ I am French.
You, we, they are French.
He, she, it is French.
- I am not old.
You, we, they are not old.
He, she, it is not old.
? Am I late?
Are you, we, they late?
Is he, she, it late?
How do we use the Simple Present Tense?

We use the simple present tense when:

* the action is general
* the action happens all the time, or habitually, in the past, present and future
* the action is not only happening now
* the statement is always true

John drives a taxi.
past present future
It is John's job to drive a taxi. He does it every day. Past, present and future.

Look at these examples:

* I live in New York.
* The Moon goes round the Earth.
* John drives a taxi.
* He does not drive a bus.
* We do not work at night.
* Do you play football?

Note that with the verb to be, we can also use the simple present tense for situations that are not general. We can use the simple present tense to talk about now. Look at these examples of the verb "to be" in the simple present tense - some of them are general, some of them are now:
Am I right?
Tara is not at home.
You are happy.
past present future
The situation is now.

I am not fat.
Why are you so beautiful?
Ram is tall.
past present future
The situation is general. Past, present and future.

Kata Kerja

We use the simple past tense to talk about an action or a situation - an event - in the past. The event can be short or long.

Here are some short events with the simple past tense:
The car exploded at 9.30am yesterday.
She went to the door.
We did not hear the telephone.
Did you see that car?
past present future

The action is in the past. 

Here are some long events with the simple past tense:
I lived in Bangkok for 10 years.
The Jurassic period lasted about 62 million years.
We did not sing at the concert.
Did you watch TV last night?
past present future

The action is in the past. 

Notice that it does not matter how long ago the event is: it can be a few minutes or seconds in the past, or millions of years in the past. Also it does not matter how long the event is. It can be a few milliseconds (car explosion) or millions of years (Jurassic period). We use the simple past tense when:

* the event is in the past
* the event is completely finished
* we say (or understand) the time and/or place of the event

In general, if we say the time or place of the event, we must use the simple past tense; we cannot use the present perfect.

Here are some more examples:

* I lived in that house when I was young.
* He didn't like the movie.
* What did you eat for dinner?
* John drove to London on Monday.
* Mary did not go to work yesterday.
* Did you play tennis last week?
* I was at work yesterday.
* We were not late (for the train).
* Were you angry?

Note that when we tell a story, we usually use the simple past tense. We may use the past continuous tense to "set the scene", but we almost always use the simple past tense for the action. Look at this example of the beginning of a story:

"The wind was howling around the hotel and the rain was pouring down. It was cold. The door opened and James Bond entered. He took off his coat, which was very wet, and ordered a drink at the bar. He sat down in the corner of the lounge and quietly drank his..."

Cara Hacking Facebook

Facebook adalah media sosial yang menghubungkan orang-orang. Di dalamnya terdapat banyak fitur mulai dari fitur chatting, real-time status update, sampai aplikasi bermain seperti poker dan City of Blood. Sebenarnya Facebook ini punya tujuan yang sama dengan Friendster yaitu menghubungkan orang (connecting people tetapi bukan Nokia loh). Facebook juga memberikan berbagai sarana interaktif pada aplikasinya. Selain itu Facebook mengimplementasikan Asynchronous Javasript atau biasa dikenal AJAX, yang memungkinkan orang mengupdate datanya tanpa harus merefresh seluruh halaman.
Sebelum Facebook, Friendster sudah berhasil di hack oleh salah satu orang Indonesia dengan cara sederhana semacam backdoor. Cara tersebut pertama-tama mengimplementasikan Javascript (Nah, ketahuan kan javascript itu bisa buat hacking) untuk me-redirect ke halaman login atau langsung saja dibuat scriptnya dan di embed kedalam Profile atau About Me. Kedua, dengan menggunakan aplikasi flash. Sudah diketahui bahwa aplikasi Flash bisa membuat orang menuju suatu web tanpa dikehendaki, misalnya anda masuk ke profile seseorang yang mengimplementasikan aplikasi Flash untuk redirect halaman, anda akan terbawa ke halaman yang mirip dengan login Friendster. Seolah-olah login time atau waktu login anda sudah habis, dan terlihat log out. Pada saat itu anda memasukkan kembali username berupa email dan password anda. Setelah itu data yang anda input tadi terkirim ke si penadah, atau si penjahat yang ingin mengacak-acak Friendster anda. Tetapi sekarang cara semacam ini sudah tidak berlaku lagi karena pihak Friendster sudah mencabut tag
