Even

USE

When a strong statement is made, the statement is often followed with an example containing "even." The word "even" adds shock, surprise, or excitement to the example.

Examples:

• He loses everything. He even lost his own wedding ring! (Her şeyini kaybetti. Evlilik yüzüğünü bile)
• John has amnesia, and he can't remember anything about the past. He can't even remember his own name! (Adını bile hatırlamıyor.)
• He could become anything. He could even become President of the United States!
• I love that author, and I have all of his books - even the ones which are out of print.

Even though Bob studied very hard, he still failed his French tests.
Bob always studied hard. But, unfortunately, he failed the tests.

Even when Bob studied very hard, he still failed his French tests.
Bob occassionally studied hard, but it didn't really make a difference. Every time he studied, he still failed.

Even if Bob studied very hard, he still failed his French tests.
Bob didn't normally study very hard. But in the rare situation when he did try to study hard, he still failed the test.

• Jerry is never happy. Even though you do everything his way, he is still dissatisfied.
  You do everything his way, but he is still dissatisfied.
• Jerry is never happy. Even when you do everything his way, he is still dissatisfied.

• Jerry is never happy. Even if you do everything his way, he is still dissatisfied.

IMPORTANT

These expressions are not always interchangeable; the context of the sentence will affect your choice:

• "Even though" is used when something is always done or a fact is mentioned.
• "Even when" is used when something is occasionally done.
• "Even if" is used when something is rarely done or just imagined.

Even So

USE

"Even so" is very much like the word "but" or "however." "Even so" is different in that it is used with surprising or unexpected results.

Examples:

• She is loud and unfriendly. Even so, I like her.
  She is loud and unfriendly, so it is unexpected that I like her.
• The bed is extremely large and heavy. Even so, Jim managed to carry it into the house by himself.
  It is unexpected that Jim could carry the bed by himself.
• Jane was sick for a couple days in Los Angeles. Even so, she said her trip to the United States was great.
  If she was sick, it is unexpected that she enjoyed her trip.

AS

Like and as are often confused in English. They can both be used to talk about how things are similar.

Like is followed by a noun or pronoun. For example, "I'm like my sister", or "Like my sister, I have brown eyes."
As is followed by a subject and verb. For example, "She's a good student, as her brother was before her."
However, in spoken English, like is often used instead of as. "She's a good student, like her brother was before her."
As is used with a preposition, such as, "As in the 1960's, the population explosion will cause some problems."
We can use as in certain expressions, such as "as you know", "as you requested", "as we agreed".
We also use as…..as to give comparisons. For example, "He's as clever as his sister."
