Reading comprehension is the act of understanding what you are reading. Communication skills help to understand a particular language, process it, and use it effectively.
Reading comprehension practice is very important for students because it improves academic performance, critical thinking skills, vocabulary, communication skills and confidence.

Reading Comprehension Test 3
Crude mineral oil comes out of the earth as a thick brown or black liquid with a strong odour. It is a complex mixture of many different substances, each with its own unique properties. Most of them are a combination of hydrogen and carbon in varying proportions. This type of hydrocarbon is found in other forms such as bitumen, asphalt and natural gas. Mineral oil originates from the carcasses of small animals and plants that live in the sea.
Over millions of years, these dead creatures build up huge deposits on the ocean floor, and ocean currents cover them with a blanket of sand and silt. As this material hardens, it becomes sedimentary rock and effectively shuts out oxygen, thus preventing the complete decomposition of the underlying marine deposits. Sedimentary rock layers are thicker and heavier. Their pressure generated heat, which converted the tiny bodies into crude oil in a process that continues today.

Reading Comprehension Test 5
Knowledge of grammar is essential for good speaking and writing, by which one’s mind is judged. Studying grammar is hard work: it has to be learned in its entirety, with no parts left out, and it demands a lot of thought and patience. But, once achieved, it can give a lifetime of joy and profit. Its study requires no physical hardship, no special room or expense.
If people spend their free time studying grammar, they can master it in a year. The author learned this in less than a year. Earning sixpence a day as a private soldier, he studied in his bed. Not being able to afford candles or oil, he read by the fire in winter (when it was his turn).

Reading Comprehension Test 6
Half a century ago, a person was much more likely to die of heart disease. Now, cancer is the number one cause of death. The problem with these words, the comparison is unfair. Cancer is the most difficult problem deeply embedded in the nature of multicellular life. Given these obstacles, cancer researchers are fighting and even winning small battles: reducing and preventing childhood cancer deaths and sometimes curing cancers that strike people in their early stages.
But when it comes to diseases of the elderly, there can be no decisive victory. Diseases that killed the bubonic plague, smallpox, influenza and tuberculosis were easy obstacles. Each had a specific cause that could be addressed. Heart disease numbers have been pushed into the future, with diet, exercise and drugs that help control blood pressure and cholesterol.

Reading Comprehension Test 7
No one can argue that acquiring knowledge is more fun and easier with computers. The mere act of touching and exploring this device constitutes an enjoyable activity for a child. This, along with a relaxed attitude and software interactivity, generally contributes to a better understanding of new knowledge. At the higher educational level, the availability of digital books, simulators and other academic materials provides the student with an always accessible source of information, which would otherwise not be at hand.
But, in addition to the increasing complexity and behaviour of intelligent software, which is usually embedded in academic digital material, the need for human interaction in the learning process will always be present, at least in the near future. A human being needs to be able to determine what each person’s specific needs are. A computer, no matter how sophisticated its software, can hardly imitate a teacher’s skill in how to explain and adapt complex concepts to different people.

What does the availability of digital books and simulators at the higher educational level provide to students?
A. A source of entertainment.
B. A source of irrelevant information.
C. A source of always accessible knowledge.
D. None of the above.
Answer: C. A source of always accessible knowledge.
What is the role of intelligent software in academic digital material, according to the passage?
A. It replaces human interaction in the learning process.
B. It helps students learn new knowledge more easily.
C. It makes the learning process more complex and difficult.
D. None of the above.
Answer: B. It helps students learn new knowledge more easily.

D. None of the above.
Answer: C. Computers can enhance the learning process, but teachers are still essential.
Reading Comprehension Test 8
The field of medicine forces a collision between scientific and everyday language. Outside the world of laboratories and clinics, there exists the daily routine of medical practice, a situation in which a doctor tries to understand the patient’s problem and the patient tries to understand the doctor’s diagnosis. The initial statement of symptoms of any disease is very important as it guides the doctor’s search for clinical signs of the condition.
Likewise, the doctor’s explanation of the problem and recommendations for treatment need to be clear and complete if the patient is to understand and follow the correct procedure.
In sensitive and serious matters like health, the need for careful listening and expression on both sides should be clear. Patients worried about their health are of ten uncertain and confused about their accounts. Busy doctors will not have time to take every point mentioned by the patient. Furthermore, the tradition of medical interviews inhibits the development of genuine communication.

Reading Comprehension Test 9
500 years later, Christopher Columbus’ ship Santa Maria was claimed to have been found by archaeological investigators led by Barry Clifford. Christopher Columbus’ flagship, the Santa Maria, was wrecked in the Caribbean. The long-lost remains of the ship were claimed to lie at the bottom of the sea off the northern coast of Haiti.

Reading Comprehension Test 10
The heart is one of the most important components of the human body. The heart of the human body has a constant job of keeping oxygen-rich blood flowing through the body. All cells in the body need a constant supply of oxygen, especially the brain. Brain cells survive only four to five minutes after being cut off from oxygen, and death ensues throughout the body. Damage to the heart muscle, valves, or pacemaker can cause heart disease. When the muscles are damaged, the heart is unable to pump properly. If the valve is damaged, blood cannot flow normally.
Dr John Gibbon of the United States developed a machine in 1953 that could temporarily take from the heart. Surgeons had the option of repairing or replacing a defective heart. Many patients have had plastic heart valves inserted when they had heart defects. Many people are now being kept alive by tiny battery-powered pacemakers.
What is the primary function of the heart in the human body?
A. To pump oxygenated blood
B. To pump deoxygenated blood
C. To maintain a steady heartbeat
D. To filter waste products

A. Four to five hours
B. Four to five minutes
C. Four to five days

What happens when the heart is unable to pump properly?
A. The brain stops functioning
B. Blood cannot flow normally
