COMPLEX SENTENCES
In the lesson on compound sentences the following example paragraph was used:
Cars cause a lot of pollution. Many cars are old and produce exhaust fumes. These cars should be banned, but people still drive them everyday. The government must make new laws. This will help to reduce pollution.
This lesson will look at subordinating conjunctions and complex sentences. Used correctly, complex sentences will improve both Grammatical Range and Accuracy scores, and Cohesion and Coherence. Below is an improved version of the previous paragraph:
Cars cause a lot of pollution, especially those that are old and produce exhaust fumes. These cars should be banned but people still drive them everyday. The government must make new laws in order to help to reduce pollution.
Subordinating conjunctions
The adjective ‘subordinating’ describes something that is under the control of another. A dependent clause is under the control of an independent clause, so a subordinating conjunction connects a dependent clause to an independent clause.
There are a large number of subordinating conjunctions. Some are single words, some are short phrases. For example:
because - while - although - when - despite - in order to - as a result of
These types of conjunction will be looked at in further detail in the next part (and here)
What are complex sentences?
As complex sentences are important in IELTS grammar, test-takers should practice using a variety before taking the test.
To connect a dependent clause to an independent clause a subordinating conjunction is used.
These conjunctions will always be directly before the dependent clause. However, complex sentences can be written with either clause first which means most subordinating conjunctions can come at the end or in the middle of the complex sentence. For example:
The government must make new laws in order to reduce pollution. (independent - dependent)
In order to reduce pollution, the government must make new laws. (dependent - independent)
There are many subordinating conjunctions (and so there is really no excuse for not using a variety). They serve a number of functions and so the most common are included in the table below alongside the type.
Different types of complex sentence.
TYPE | CONJUNCTIONS |
To show cause | because / as* / since / so that / in order to / in order that / due to / as a result of |
To show place | where / wherever |
To show time | when / whenever / as* / while* / after / before / until / as soon as / as long as / once / now that |
To show concession | although / even though / though / despite |
To show comparison or contrast | whereas / in contrast to / just as / while / though |
To show condition | if / unless / even if / in case / provided that / when |
To add a non-defining relative clause | which / who / whom / where / whose |
As previously stated, to achieve a band 7 test-takers must show a range of complex sentences.
In reality, if test-takers use several different subordinating conjunctions in the IELTS essay this requirement will be reached. However, when preparing for the IELTS test it is a good idea to also understand their semantic function.
Time
Time-related conjunctions show the time when the main action was or will happen. These include after, before, as soon as, as long as, now that, once, still, until, when, whenever, and while.
Most students spend hours looking at social media after they should have gone to bed.
Before work can begin on major improvements, money must be raised.”
Concession
Concession conjunctions show that one action is somehow less important than another, often because something (more important) happened although a (less important) situation threatened to cause a problem. These include although, despite, and even though.
Despite protests from environmentalists, the government decided to build the airport.
Thousands of refugees died even though there was an attempt to provide aid.
Comparison
Comparison conjunctions show how something is similar or dissimilar to the independent clause. These include just as, though, whereas, in contrast to, and while.
Online news sources experienced a rapid growth in contrast to print media.
Whereas young students often lose interest, mature students tend to be focused and motivated.
Cause
Cause conjunctions give a reason for the action in the independent clause. These normally include as, because, in order that, since, and so that.
The birth rate in developed countries may need to increase in order to avoid financial strain on government services.
Due to flooding in the region, the cost of house insurance rose dramatically.
Condition
Condition conjunctions introduce rules that restrict the independent clause. These are most commonly even if, if, in case, provided that, when and unless.
If there is no international cooperation, there will be no improvement in the lives of the worlds poorest.
Working from home will never be a viable option unless employer pay for the equipment.
Place
Place conjunctions, which determine where activities might occur, include where, wherever, and whereas.
Tourists should not be allowed to walk wherever they please.
In countries where newspapers were not controlled by the government, corruption levels were significantly lower.
Be careful. Avoid using a coordinating conjunction in a complex sentence. When a subordinating conjunction is used on the dependent clause, a coordinating conjunction should not be used on the connected independent clause.
Although pollution levels drop dramatically during national holidays, but this situation only lasts a short time. ✘
Although pollution levels drop dramatically during national holidays, this situation only lasts a short time. ✔︎
