AAS students which have just about 37% students, submit assignments on time.
You seem to be saying that AAS students are not completely AAS students – 63% of each AAS student is not an AAS student!?
Perhaps you mean:
- AAS students, who represent just about 37% of all students, submit assignments on time.
You are much more likely to make sense if you construct a noun phrase in which your percentage number is followed by ‘of’:
x% + of + ‘the whole’(???) + verb + etc.
Make sure you state the whole explicitly. For example if you are discussing male and female representation among students, then the ‘whole’ is students. If you want to say that 50% of students are female, do not write 50% of females are students. For a more detailed look at what I mean by the ‘whole’, take a look at my post Don’t forget the whole.
Use this structure with the first two or three numbers that apply to each new theme that you introduce and your reader will understand what the numbers refer to. You will also receive a good score in IELTS in all four assessment criteria (see public band descriptors).
Some Asians have less difficulty in intercultural communication.
If your reader speaks Indonesian he will understand that you’re translating kurang. Other readers, however, will begin to ask themselves:
Is he comparing Asians with some other group of people?
Is he comparing difficulty in intercultural communication with some other kind of difficulty?
Is he comparing difficulty in intercultural communication with some other kind of communication?
What is he comparing?!
If you’re an Indonesian translating kurang then you’re probably not comparing anything. You’re simply saying:
- Some Asians find intercultural communication easy.
As a general rule, when you use comparative adjectives, include the thing or things that you’re comparing in the same sentence. If you’re not comparing things, then don’t use a comparative adjective.
In the last 10 years there is an increase in aquaculture.
Context is important. Context is generally about time and place. If you want to contextualise time then you need to communicate meanings such as:
- time around now
- time up to and including now
- past and finished time
- past unfinished time
- future time related to the present
Time context is achieved using carefully chosen verb tenses and time expressions. In the sentence above, “in the last 10 years” is a time expression that carries the meaning time up to and including now. In this case the correct tense is present perfect:
- In the last 10 years there has been an increase in aquaculture.
Create time context using verb tenses and time expressions. Make sure your verb tenses and time expressions match!
Population is indeed growing, but after 2050 it will likely to decline slightly.
Another collocation problem. Use one of the following instead and never mind why. Just do it.
- Population is indeed growing, but after 2050 it is likely to decline slightly.
- Population is indeed growing, but after 2050 it will most likely decline slightly.
And make sure you complete the structure with a verb:
- s.th. / s.o. + is likely to + V1
- s.th. / s.o. will most likely + V1
Several researches have proven that nuclear energy is not as dangerous as people think.
Actually there’s nothing ‘wrong’ with this. I just looks odd to a native speaker because research is nearly always uncountable:
- Much research has proven that nuclear energy is not as dangerous as people think.
Investigate the differences between research and researches. Then try googling to see which form of the word is more common.
The fallopian tube is a tunnel which will be passed by the sperm on its way to the egg.
This might be possible if all the sperm does is pass by the entrance to the tunnel without actually entering it. But then it won’t be on its way to the egg, it will be on its way somewhere else!
If you want to say that the sperm enters the tunnel, travels along it and then meets the egg, you need to use a preposition that carries that meaning:
- The fallopian tube is a tunnel which the sperm passes through on its way to the egg.
Compare these situations:
- A > B: The sperm passes through the tunnel.
- C > D: The tunnel is passed by the sperm.
- D > E: The tunnel is passed by the sperm.
Indonesians take care when you’re translating melalui, melintasi, menyebrangi, and melewati.
People in the 14-17 group of age were most affected by the changes.
I know, this seems to make sense, and your meaning is clear, but if you want a high score for vocabulary you need to use better collocation inside your noun phrases:
- People in the 14-17 age group were most affected by the changes.
The following are all possible. Unfortunately you just have to memorise them. Try to use them as soon as possible in your writing practice and soon they will become automatic.
- a person who is 49 years of age
- a person who is 49 years old
- a person who is 49
- a 49 year-old person
- a 49 year-old
More often in IELTS, ‘person’ is plural (= ‘people’), and so these noun phrases are also possible:
- 49 year-olds
- 49 year-old people
- people in the 50-60 age group
- people aged between 50 and 60
- people aged 50-60
- people (who are) 50-60 years old
Of course we could be more specific about ‘person’ or ‘people’:
- A 49 year-old English teacher
- English teachers in the 49-59 age group
In the second process, the sperm enters the egg, and the zygote is formed.
It’s difficult to imagine more than one process here. I think you mean:
- In the second stage of the process, the sperm enters the egg, and the zygote is formed.
In English a process can occasionally be broken down into sub-processes, but normally we talk about these as stages. Indonesians often make the same mistake with menu and items on a menu:
- The second menu is ayam lalapan.
- The second item on the menu is ayam lalapan.
Since the abolition of fuel subsidies, prices have been fluctuative.
Nice try! The IELTS examiner will understand that you are trying to make an adjective from the verb ‘fluctuate’ using ‘ive’. Normally this would be a good strategy, but there is no such word as ‘fluctuative’ and so this time you will receive a low score for vocabulary.
The safest approach is to use the verb form:
- ..prices have fluctuated.
Alternatively, you can make an adjective phrase using the noun form and featuring some collocation:
- ..prices have been subject to fluctuation.
Finally you might try some more fancy academic collocation:
- ..prices have tended to fluctuate.
Now go ahead and remove fluctuative from your list of ‘ive’ adjectives!
Past perfect tense needs to be handled with care. It is most useful in the narrative genre and is seldom needed in Task 2 writing. However, Task 1 essays occasionally present an opportunity to use past perfect.
Let’s try an exercise! Follow my instructions carefully and attempt the tasks before reading my sample texts.
- Look at the following graph and attempt to describe it in two short paragraphs. The first paragraph will focus on general trends and will begin:
The second paragraph will describe details and will begin:
When you’re happy with your writing, you can read my sample text.
- Finished writing? OK now take a look at my sample text and analysis.
- Take another look at your own text. Did you use my past perfect structure? If not, can you edit your text so as to include it in at least one sentence? Please share your writing in the comments section!
