P R E S N T	I am a student of a master’s program. My master’s degree gives me more opportunities in certain job markets.	At present I’m earning a master’s degree.	I graduated from the University last year. I have just applied for a master’s degree and now I’m a graduate student of the master’s degree program in Chemistry.	Since I choose the master’s program in petrochemistry I have been studying a variety of specialized courses.
P A S T	I applied for a master’s degree 2 years ago.	Our research group was working at this project for 2 years.	I decided to improve my knowledge and skills, so I had applied for a master’s program of my interests.	I was very busy as I had been writing my thesis.
F U T U R E	Next year I’ll be a master of science in chemistry	We’ll be working with natural samples during our field studies during next 2 weeks.	In the nearest future the majority of employers will demand a highly qualified staff. I will have been a M.Sc. by this time.	By next summer I’ll have been experiencing for a year, it will help me to complete my thesis.

Appendix II passive voice: When to Use It and When to Avoid It

Use Passive Voice	Avoid Passive Voice
1. The person is unknown or irrelevant: The first alchemy records were found in Egypt. (We don't know who made them.) An experimental solar power plant will be built in the Australian desert. (We are not interested in who is building it.).	1. When you are to refer to the exact data. Refer to figures, tables, and equations at the beginning of the sentence rather than at the end. Figure 1 illustrates the quadratic relationship between distance and velocity.
2. You are writing in a scientific genre that traditionally relies on passive voice. Passive voice is often preferred in lab reports and scientific research papers, most notably in the Materials and Methods section: The sodium hydroxide was dissolved in water. This solution was then titrated with hydrochloric acid. In these sentences you can count on your reader to know that you are the one who did the dissolving and the titrating. The passive voice places the emphasis on your experiment rather than on you.	2. Do the same with words and phrases such as "results," "studies", and "evidence". Experimental evidence shows that the typical dose-response curve has an inverted J-shape. If you are referring to a technique or procedure, you can also achieve greater directness by making it the subject of your sentence: PCR analysis produced clones of the toxin B DNA. Thorough investigations resulted in the conclusion that the previous interpretation was improper.
3. Passive voice helps to emphasize the objectivity of the sciences or the person / thing acted on. The element radon was discovered in 1900. Test-samples were flushed out by the diluted acid.	Some students use passive sentences to hide holes in their research: That phenomenon had been already considered long before current researches. (I couldn't find out who considered it)
4. You are talking about a general truth: Rules are made to be broken. (By whomever, whenever.)	4. Academic writing often focuses on differences between the ideas of different researchers, or between your own ideas and those of the researchers you are discussing. Too many passive sentences can create confusion: Research has been done to discredit this theory. (Who did the research? You? Your professor? Another author?)
5. You want to be vague about who is responsible: Contradictions in terms were noticed. (Common in bureaucratic writing)	5. Finally, passive sentences often sound wordy and indirect. they are usually longer than active sentences. They can make the reader work unnecessarily hard. Since the car was being driven by Michael at the time of the accident, the damages should be paid for by him.
Sometimes you may find that the sentences in active voice are stronger, shorter, and more precise:
The possibility of cold fusion has been examined for many years.	Physicists have examined the possibility of cold fusion for many years.
