Đề bài:Read the following passage about tooth decay and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions from 21 to 30. 
(I) The cause of tooth decay is acid, which is produced by bacteria in the mouth. (II) The rate at which bacteria in the mouth produce acid depends on the amount of plaque on the teeth, the composition of the microbial flora, and whether the bacteria of the plaque have been "primed" by frequent exposure to sugar. (III) To keep your teeth healthy, a regular dental hygiene program should be followed. (IV) 
Removing plaque with a toothbrush and dental floss temporarily reduces the numbers of harmful bacteria in the mouth, thereby lowering the risk of tooth decay. This practice also makes the surfaces of the teeth more accessible, which enables saliva to neutralize acid and remineralize lesions. If fluoride is present in drinking water when teeth are forming, some fluoride is incorporated into the enamel of the teeth, making them more resistant to attack by acid. Fluoride toothpaste seems to act in another way, by promoting the remineralization of early carious lesions. 
In addition to a regular dental hygiene program, a good way to keep your teeth healthy is to reduce your intake of sweet food. The least cavity-causing way to eat sweets is to have them with meals and not between. The number of times you eat sweets rather than the total amount determines how much harmful acid the bacteria in your saliva produce. But the amount of sweets influences the quality of your saliva. Avoid, if you can, sticky sweets that stay in your mouth a long time. Also try to brush and floss your teeth after eating sugary foods. Even rinsing your mouth with water is effective. 
Whenever possible, opt for foods with fiber, such as raw carrot sticks, apples, celery sticks, etc., that naturally scrape off plaque, acting as a toothbrush. Following these guidelines when consuming sweets and maintaining a thorough oral care routine can significantly reduce the risk of cavities and improve overall dental health.

Đề bài:Read the following passage about skulls and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions from 1 to 8. 
The hours we spend scrolling through our smartphones appear to be changing the shape of our skulls. This may be the reason why some people - especially the younger crowd - are developing a weird, bony spike just above their necks. This spike, known as an external occipital protuberance, appears at the lower end of the skull, and is sometimes so large, you can feel it by pressing your fingers on the base of your skull. 
A study published in the Journal of Anatomy found that the spike was becoming more frequent - especially among 18 to 30-year-olds. David Shahar, the Australian health scientist who conducted the research, believes the development was triggered by prolonged use of smartphones or tablets. As people tilt their head forward to look at the screen, they put pressure on where the neck muscles meet the skull, so the body then develops more bone layers to be able to withstand it, said Shahar. 
In the study, Shahar and a colleague looked at the radiographs of 218 young patients, aged 18 to 30, to determine how many had these spikes. In all, 41% of the group had an enlarged spike and 10% had an especially large spike measuring at least 0.7 inches (20 mm), the doctors found. In general, enlarged spikes were more common in males than in females. The largest spike belonged to a man, sticking out at 1.4 inches (35.7 mm). 
Shahar believes that the spikes will continue to grow in size as people keep hunching over their handheld devices, but adds that they should not be very harmful and rarely cause serious medical issues. "But if you are experiencing discomfort, maybe you should try improving your posture," he said.
