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 principle of the social services is that people have rights to live happily and without discrimination.
I know, I know. You mention more than one right. Normally your teacher would be yelling at you to add an ‘s’. But this is a vocabulary/collocation issue.
- The principle of the social services is that people have the right to live happily and without discrimination.
You can think of it as a phrasal verb (Indonesians will be translating berhak untuk..). Sometimes it’s have the right to + V1. Sometimes have a right to + V1.
Try googling “have the right to” and then “have rights to”. Which is more common? Which is the meaning that you want?
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.
There are many factors that can contribute to failure such as students do not manage their time well, or they are just lazy.
In this example, such as is followed by independent clauses whereas it should be followed by noun phrases:
- There are many factors that can cause students to fail such as bad time management, or just laziness.
If you really want verb phrases, then use for example:
- There are many factors that can contribute to failure, for example students do not manage their time well, or they are just lazy.
(Remember to put a comma before for example!)
Notice that for example is a more flexible signal as it can be used to introduce either a noun or a verb phrase. In the next example it is used to introduce nouns.
- There are many factors that can contribute to failure, for example financial pressure and physical injury.
Agricultural sector is different from economic sector in the way research is conducted.
First of all in English we tend not to label nouns as much as you do in Bahasa Indonesia. An easy example is colours. In English when we mention colours, it isn’t necessary to use the word ‘colour’:
- Saya suka warna merah.
- I like blue.
Therefore our opening example could easily be written:
- Agriculture is different from economics in the way research is conducted.
However, if you must use the word ‘sector’, and if you are talking about specific sectors, then you need to communicate this one exactly:
- The agricultural sector is different from the economic sector in the way research is conducted.
If you do not use ‘the’ when you mean this one exactly then you will receive a low score in IELTS for grammar and for coherence and cohesion. If you do not use ‘the’ when you mean this one exactly then your reader will stop reading and think “Does he mean this one exactly, or does he mean one of many, or does he mean all of them everywhere?” You must communicate one of these meanings if you want to be understood clearly.
If you want to communicate one of many then you need to use ‘a’:
- Agriculture is a sector that requires different research approaches.
(This implies that, in addition to agriculture, there are other sectors, like education, which also require different research approaches.)
If you want to communicate all of them everywhere then you need to use ‘s’:
- Government sectors include health, education, agriculture and economics.
Passive smoking brings negative impact for people who do not smoke.
This is a collocation problem for Indonesians translating “..membawa dampak negatif untuk..”
In English the collocation is:
- Passive smoking has a negative impact on people who do not smoke.
Note! s.th./s.o. has + an impact + on + s.th./s.o.
Using the correct collocation will have a very positive impact on your IELTS score for vocabulary in both speaking and writing!
You can listen to a song featuring ‘impact’ here.
The growth of cashless payments has raised the debatable issue whether this payment method is part of the problem or part of the solution.
One problem here is that the issue is the growth of cashless payments, while one aspect of the issue is whether or not it is useful. Another problem is that an issue is normally raised by someone.
It would be better to begin with someone raising the issue, and then focus on a specific aspect of the issue:
- In a recent meeting the prime minister raised the issue of the growth of cashless payments. We discussed whether this payment method is part of the problem or part of the solution.
Note this structure: raise the issue + of + [name of issue]
Alternatively you might avoid doing any raising of issues and stick to more standard cause / effect:
- The growth of cashless payments has caused much debate about whether this payment method is part of the problem or part of the solution.
Whatever you decide, note that in English raise collocates strongly with issue. Otherwise it goes together with things like ‘your hand’, ‘the Titanic’ and other items that need to be lifted from a lower position to a higher position. If this is not the meaning of raise that you are trying to communicate then your IELTS score for writing and speaking may go down, rather like the Titanic!
