Vocabulary notes (text only) explain key vocabulary and phrases from the interview.


imageTree snakes were accidentally released.

In English, we often use the word "accidentally" to talk about mistakes. If we do something that was unplanned and a mistake, we say it was "an accident" or we "accidentally" did it. Notice the following:

  1. I accidentally left the air-conditioner on.
  2. We accidentally sent your letter to the wrong address.


imageThey subsequently destroyed the bird population.

When something happens 'subsequently', that means it happens as a result of something else or because of something else. The adverb 'subsequently' is very close in meaning to the adverb 'therefore'. Notice the following:

  1. I ate pizza every day and subsequently gained a lot of weight.
  2. He cheated on his wife. Subsequently, she divorced him.


imageThe vines essentially ambush the plants and cover them.

Here the word 'essentially' means 'basically' or 'simply'. We use the word 'essentially' to express a simple idea for a more difficult concept. Notice the following:

  1. Because he was always joking around at work, he made the boss angry and 'essentially' lost his job.
  2. If you never save any money, you are 'essentially' risking your future.


imageThey keep sunlight from ever reaching them.

We use the word 'ever' to mean any time or at any time in the past, present or future. The word 'ever' is often not needed in the sentence but is used to add emphasis. Here are some samples.

  1. I don't ever buy the newspaper anymore. (don't ever = never)
  2. If you drink this soup, it will keep you from ever getting sick.


imageCan you imagine a building covered completely in thick vine?

The word 'completely' is used to mean 100% or totally. Below are some samples:

  1. I completely agree with you.
  2. My shoes were completely ruined by the rain.
