DAT Reading Comprehension Test 2
Reading Comprehension Test for the Dental Admissions Test (DAT)
Here is a practice Reading comprehension Test for the Dental Admissions Test (DAT). To simulate a real Dental Admissions Test (DAT) give yourself no more than 60 minutes to complete the test. This is a complete reading comprehension test for the Dental Admissions Test (DAT).
Start Reading the passage below, you have 60 minutes to complete the test.
| 1 | Myopia is worsening in Singapore |
| Surveys have indicated that myopia afflicts 25 percent of seven-year-olds, 33 percent | |
| of nine-year-olds, 50 per cent of 12-year-olds and more than 80 percent of 18-year-old | |
| 5 | males. There is still no complete explanation for the development of myopia, though |
| there is a genetic factor which makes certain people and ethnic groups more susceptible | |
| to it. However, this does not explain the rapid increase in the prevalence of myopia | |
| here over the last three generations. This suggests strongly that environmental | |
| influences interacting with 10 genes have played a major role. | |
| 10 | |
| A recent study in the US suggests that leaving the lights on at night when babies are | |
| asleep might predisposes them to developing short-sightedness. The condition has been | |
| induced in chicks, tree shrews and monkeys simply by manipulating their visual | |
| environment. This is further evidence of the major role played by the environment. While | |
| 15 | the exact environmental factor cannot be pinpointed yet, it is quite likely that this is |
| related to the heavy amount of reading and near work Singapore children are exposed to, | |
| which is certainly much higher than that in the past. | |
| Myopia arises when the eyeball grows too long. Once this growth has occurred, it is not | |
| 20 | reversible. However, there is also another type of spurious myopia that is due to |
| excessive spasms of the internal focusing muscles within the eye. This type of spurious | |
| myopia can be reversed by relaxation techniques, and practitioners of this art sometimes | |
| claim wrongly that they have “”cured” short-sightedness. | |
| 25 | Although true myopia is irreversible, it can be compensated for by wearing spectacles, |
| contact lenses or undergoing surgery to flatten the cornea. However, the blinding | |
| complications of myopia, for example, retinal Detachment and myopic macular | |
| degeneration are related to the excessive length of the eyeball. Consequently, the | |
| methods outlined above compensate for myopia, but do not prevent the late | |
| 30 | complications of it because they do not actually prevent the excessive elongation of |
| the eyeball. | |
| Once myopia sets in, it will continue to worsen until the child reaches adulthood. The | |
| earlier the onset, the worse the final outcome will be. The challenge is to either prevent | |
| 35 | it from developing in the first place, or to slow down its progression. |
