Talking about Verbs
Now that you're studying English at a higher level, you need to be able to talk about the language itself.
One of the biggest areas of confusion for students is the difference between the past tense and the present perfect.
The past tense is indicated by use of the past tense marker, represented here by V(d).? ? ? ? (sub)
Here are some examples of regular verbs and their past tense forms.
V? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? V（d）
walk? ? ? ? ? ? ? ? ? ? ? ? ? walked
wait? ? ? ? ? ? ? ? ? ? ? ? ? waited
arrive? ? ? ? ? ? ? ? ? ? ? ? arrived
open? ? ? ? ? ? ? ? ? ? ? ? ? opened
close? ? ? ? ? ? ? ? ? ? ? ? ? closed
So, as you can see, for regular verbs the past tense forms is indicated by the addition of an -ed at the end of the verb.
However, some of the most common verbs in English are irregular, so it is important to learn them.
Here are some examples.
? V? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? V（d）
eat? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ate
drink? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? drank
get? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? got
take? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? took
come? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? came
be? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? was/were
Altogether there are over 200 irregular verbs in normal use.
Which of these words is irregular? - mislead
Which of these words is regular? - ignore
Many people think that the past tense form only indicates past time.
However, that is only one of the possible meanings.
The past tense form is also used to express something that is unlikely or imaginary,from the speaker's point of view.
Here is an example: "He wishes he had a car."
The fact is that he doesn't have a car, so the use of "had" indicates that it isn't real :it's imaginary.
“If he had a car, he could drive us to school.”
Again, "he doesn't have a car, so he can't drive us to school."
This condition expresses something that isn't a fact.
It's a counter-factual condition, which means it goes against what we know or believe.
Which condition is counter-factual or imaginary? — If she worked here instead of at another company...
Which condition is counter-factual or imaginary? — If the Earth is square instead of round...

Look at these two sentences.
If? she waits another week, she can save money…
If? she waited another week, she could save money because there’s? going to be a sale.
Both sentences are correct, but there is a difference in meaning.
In the top sentence, the condition that she waits is more likely from the speaker's point of view.
In the bottom sentence, the speaker thinks it's less likely that she's going to wait.

He doesn't have a car, so he can't drive us to school.
There was a big sale last week, so we all went shopping.
If that flight left a few minutes later, we could take the next shuttle bus.
I wish we didn't have to run, but if we don't hurry, we'll miss the next bus.

If that flight leaves on time, we're going to miss it, so let's run.
If that flight leaves on time, the next shuttle bus may not get us to the airport on time.
If that flight left an hour later, we wouldn’t have to get to the airport so early tomorrow morning.
L6-U1-P2-2 Listening : Takling about Verbs 2
When we talk about experience or results, we use the present perfect form.
This form uses "have" followed by the participle.
For regular verbs, this participle is identical to the past tense form.
V? ? ? ? ? ? ? ? ? ? ? V（d）? ? ? ? ? ? ? ? ? V(n)
walk? ? ? ? ? ? ? ? walked? ? ? ? ? ? ? ? walked
wait? ? ? ? ? ? ? ? ? waited? ? ? ? ? ? ? ? waited
arrive? ? ? ? ? ? ? arrived? ? ? ? ? ? ? ? arrived
open? ? ? ? ? ? ? ? opened? ? ? ? ? ? ? opened
close? ? ? ? ? ? ? closed? ? ? ? ? ? ? ? closed
For irregular verbs, this participle is often different.
V? ? ? ? ? ? ? ? ? ? ? ? V（d）? ? ? ? ? ? ? V(n)
eat? ? ? ? ? ? ? ? ? ? ? ? ? ? ate? ? ? ? ? ? ? ? ? ? ? eaten
drink? ? ? ? ? ? ? ? ? ? ? drank? ? ? ? ? ? ? ? ? ? drunk
get? ? ? ? ? ? ? ? ? ? ? ? ? ? got? ? ? ? ? ? ? ? ? ? ? ? got
take? ? ? ? ? ? ? ? ? ? ? ? took? ? ? ? ? ? ? ? ? ? ? taken
come? ? ? ? ? ? ? ? ? ? ? came? ? ? ? ? ? ? ? ? ? ? come
be? ? ? ? ? ? ? ? ? ? ? ? ? was/were? ? ? ? ? ? ? ? been
When we use the perfect form, the primary focus is on the subject of the sentences, not the verb.
It emphasizes condition, experience or results rather than actions or events.
In these two examples, we see the contrast.
She has already left the hotel.
She left the hotel a few minutes ago.
The top sentence gives the condition or state of the subject and the bottom sentence expresses an event.
The top sentence describes the condition of the subject of the sentence, she, rather than an event.
The fact that she has left the hotel is now a part of her experience, or state of being.
The bottom sentence expresses the action, or event: "she left," which is something she did.
In general, the past tense form expresses of events or acts, and the perfect form expresses the experience or conditions.
When we use the perfect form of the verb we focus on the state of the subject and not an action or event.
When we use the perfect form, the primary focus is on the subject of the sentences, not the verb. It emphasizes condition, experience or results rather than actions or events.
-The train arrived ten minutes ago.
(1) In high school, John wasn’t a very good student.
(2) In fact, he was one of the worst students.
(3) When it came time to go to university, nobody expected him to pass the entrance examination.
(4) However, he proved them wrong and did well enough to get into a top university.
(5) He enjoyed his studies and graduated a few months ago.
(6) Now that he has graduated, he’s ready to get a job.
Which sentence expresses state of being?? -The express train has already left.
Which sentence expresses an event rather than a state or process?-She ate a large lunch.
He enjoyed his studies and graduated a few months ago. Now that he hasgraduated, he's ready to get a job.
Note that the past form expresses events at specific points or periods of time, such as last year or the past five years.
He worked at several companies(in the past)
He finished the project last week.(in the past, last week)
These events are distanced from the speaker's point of view.
The perfect form expresses the state of something from the speaker's point of view, not distanced in time.
He has worked at several companies.(his experience now)
He has finished the project.(his experience now)
These two sentences are incorrect in confusing, because they give two different points of view.
He has worked at that company until last week.(incorrect)
He has finished the project last week.(incorrect and confusing)
Which sentence is strange? - He has finished his work last week.
Which sentence is strange? - He has eaten lunch an hour ago.
Here are some sentences that use the perfect form.
He has finished practicing.
He has been practicing.
She may have eaten.
Her computer may have been stolen.
Some are simple, such as the first one, and some are complex, like the last one.
The last one is complex because it combines many verb forms,including the passive.
He has practiced hard…so he should do well in the competition.
He may have been injured in the explosion.
The game has started already.
He may have taken his computer with him, but I’m not sure if he did or not.
He may take his computer with him, but he still hasn’t decided.
His computer may have been taken by somebody.
One of the biggest areas of confusion for students is the difference between the past tense and the present perfect.
In general, the past tense form expresses of events or acts, and the perfect form expresses the experience or conditions.
He took his computer with him ...because he wants to work at home.
The weather has gotten worse.
He must have taken her computer with him.
He may take his computer with him,? but he still hasn't decided.
The past tense form is also used to express something that is unlikely or imaginary, from the speaker's point of view.
It's a counter-factual condition, which means it goes against what we know or believe.
He may have been traveling when he got sick.

L6-U1-P2-4 Reading : Winter in Antarctica
Winter in Antarctica : Staying sane at the Bottom of World
On Antarctica, the world's coldest continent, the average high temperature is -49 degrees Celsius. In the summer, the sun never sets, and in the winter, it never rises. Keeping sane there is its own special challenge. The McMurdo Station is a research base perched on the edge of the Ross Ice Shelf, the world's largest body of floating ice. The station is administered? by the United States and is the largest community in Antarctic.
Capable of supporting more than 1200 residents, thepopulation of the stationdrops to 150 brave (perhaps foolish) people when winter begins in March.Their task is to maintain the station during the months of total night. The biologists, astronomers, geologists, and climate scientists who were there before, have gone, as any research is impossible in thebrutal winter.
Every day the remaining staff of maintenance personnel perform their routine tasks and make repairs when needed.Sometimes they peer through the darkness toward their friends from New Zealand, at Scott Base, about two miles away. Though most of the time they're just voices on the radio, it's nice to have neighbors not too far away.Together, they share a power grid and one coast of a dark forbidding continent.
Though the days are dark and freezing cold in the depths of winter, the moon will rest above the horizon for weeks at a time, Its pale light illuminates the cold, craggy landscape as if acknowledging a companion and reaffirming the bonds of life, So even for those who live in the darkest part of the Earth, there's light.

L6-U1-P2-5 Reading : Chernobyl
Chernobyl : Lessons from Nature
On April 26, 1986, Unit 4 of the Chernobyl nuclear reactor in northern Ukraine, then a part of the Soviet Union, was shut down for an unauthorized safety test. When the nuclear fuel rods hit the cooling water, the fission reaction accelerated out of control due to a sudden power surge. This caused the reactor tooverheat and build up pressure until its structure failed and it blew up, releasing large amounts of radiation. It took officials a whole day to comprehend the scale of the disaster and to order an evacuation of the surrounding area. Some 50,000 people had to leave, not knowing that they would never return.
In the following months, massive efforts were made to decontaminate the area while increased radiation levels were detected across much of Europe. Fallout from the disaster continues to this day, decades later, and long-term effects such as cancers are still being investigated. Estimates of the number of deaths that will eventually result from the accident vary enormously.
The forest area near the reactor site is one of the most radioactive places on Earth.Named the Red Forest because its trees turned a reddish-brown color as they died, the forest is trying to make a recovery. Animals such as elk and eagles have been seen in the area. And birch trees grow where the radioactive trees of the forest were bulldozed and buried by the Soviet government.
Some people have returned as well, mostly former residents who returned illegally after the evacuation.The old company town of Pripyat,once home to 50,000 plant workers is still deserted, but is slowly being reclaimed by the forest. It seems that nature can recover and even thrive where humans cannot.Let's hope that humans can learn from this experience. Chernobyl, and more recently, Fukushima in Japan, have lessons to teach us.
What is the purpose of this text ? It's to educate.
-The nuclear reactor exploded because too much pressure built up inside.
If something is contaminated, it ...can't be used because it contains harmful substances.
If something is thriving it is ...doing well.
