Road safety


Globally, roads are deadlier than HIV, malaria or murder. The tragedy is that this is so easy to change.


In many poor countries, especially African ones, road accidents are killing more people. Those countries have swelling, young populations, a fast-growing fleet of cars and motorbikes, and a limited supply of trauma surgeons. It is impossible to know for sure because official statistics are so inadequate [Adverbial subordinate clause], but deaths are thought to have risen (present perfect) by 40% since 1990 in countries that the World Bank defines as low-income, such as Afghanistan [Object relative clause]. In many rich countries, by contrast, roads that were pretty safe are becoming (present continuous) even safer [Subject relative clause]. In Estonia and Ireland, the number of deaths has fallen (present perfect) by about two-thirds since the late 1990s [Adverbial subordinate clause].


The most important and intriguing changes are taking place (present continuous) in middle-income countries, such as Thailand. These contain most of the world’s people and have some of the most dangerous roads. They also tend to be close to an inflection point. In China and South Africa deaths have been falling (present perfect continuous) since about 2000, according to IHME—though crashes still claim about a quarter of a million Chinese lives each year [Adverbial subordinate clause]. In India deaths peaked in 2012. It is possible that the Philippines reached a peak four years ago [Extraposed subject clause]. In Kenya and Nigeria deaths are still rising (present continuous).


Yao's comment:

As can be seen above, a successful writing of IELTS Task1 demands variety of grammar including sentences and tenses. Please don't expect that memorising any template may help you pass the exam, although this cunning strategy has been widespread across the country.
