One of my common grammar mistakes is verb tense, and I will look into detail of the usage of present perfect tense and present tense. Let’s study this example situation, Jason and John are gay. They are married. They got married exactly 2 years ago, so today is their 2nd wedding anniversary.
How long have they been married? (Present perfect)
(not How long are they married?).
They have been married for 2 years.
(not They are married for 2 years).
We use the present perfect to talk about something that began in the past and still continues now. Compare the present and the present perfect:
Jason is in school.
But He has been in school since yesterday.
(not Jason is in school since yesterday)
Do you know each other well?
But Have you known each other for a long time?
(not Do you know)
For present perfect tense, there are present perfect simple and present perfect continuous. For example, I have worked/lived/done etc. is the present perfect simple; while I have been watching/been doing/ been reading etc. is the present perfect continuous.
When we ask or say ‘how long’, the continuous is more usual.
1. I have been watching TV for 2 hours.
2. It has been raining since yesterday.
3. Jason has been doing the same job for 2 years.
However, do take note that there are some exceptions for some verbs. For example,
(know/like/believe) are not normally used in the continuous:
1. How long have you known Jason? (not have you been knowing)
2. I have had stomachache all day. (not I have been having)
We can use present perfect continuous or simple with live and work:
1. Jason has been living / has lived in Singapore since 3 years ago.
2. How long have you been working / have you worked here?
Exercise:
Jason and John are planning to have lunch at a restaurant. It is an unpleasant experience as they think the waiter (forget) __________ them because they (wait) __________ for over half an hour and nobody (take) __________ their order yet. The waiter (walk) __________ by them at least twenty times. John suspects that the waiter would probably think that they (order, already) __________. Meanwhile, Jason saw a couple, who (be, only) __________ there for five or ten minutes and they already have their food. He complains that the waiter should realize that they (order, not) __________ yet and in fact, they (sit) __________ there over half an hour staring at the waiter. However, John is not sure if the waiter (notice, even) __________ them because the waiter (run) __________ from table to table taking orders and serving food. In the end, they leave the restaurant without having their meal.

EG1471- Portfolio 1
I agree with Prof Seeram Ramakrishna, article two with his idea in changing the face of engineering. I reckon that the notion of the companies, organizations and even nations need a workforce, especially engineers that does not ‘fear’ technology but embraces and thrive it, is the most important aim to the engineering profession in future.
In the early 1990s, the time when the economic and technology are in the most advancing pace, people were clueless and helpless with the progress of this technology evolution. It is understood that most people found it difficult to adapt with this transition of technology advancement, where they needed to switch from typewriter, to computer keyboard. While for engineers, it proved to be tough for them too because they used to judge the matters based on experience, but with the newly technology tools, they needed to judge the matters based on system approach. As a result, during that time, it had contributed to unexpected and adverse situations, where people tried to keep pace with the progress of technology. Although it takes time for adjustment, yet the nation needs a workforce that has ‘gut’ to face technology. To me, engineering profession should be ‘fearless’ when it confronted with the adversity of technology.
According to Prof Seeram, engineers’ training helps to systematically analyze complex information and apply a holistic approach in designing solutions. It is vital to engineers, as what they have been gone through is totally different from other profession, such as business, IT or art. If our future engineers failed to embrace on the challenge of new technology, it will not only be a drag to country’s economic development, it will also affect the people’s daily life, as engineers fail to address the people’s needs. Therefore, engineers should always be upgrading themselves with the new technology knowledge and accept the idea of the technology advancement with an open mind, as I firmly believe the future of the world, is in the hands of engineers.
