Colds and flu are caused by viruses. The infections are contagious, passed on by tiny droplets and hand contact. There are hundreds of different types of virus that can cause cold, which explains why children get repeated colds. Flu is caused by the influenza virus. There are three major types: A (often the cause of flu epidemics), B and C. The flu virus is constantly changing its structure, so new strains appear each year. We don’t have immunity to the new strains, which is why we can catch flu repeatedly. Anyone can catch a cold or flu. The peak season for colds is the colder winter months, not only because of the weather but because central heating dries out the normally moist nasal mucosa-an important defense against invading viruses. However, you can catch a cold at any time of the year; one particular type of cold virus thrives in the summer. Flu rarely occurs outside November to February in the UK. A cold causes a stuffy or runny nose, sneezing, sore throat, cough, mild fever and tiredness, lasting from two to four days. Flu is more severe with a high fever (usually 39oC or above), chills, headache, intense muscle pains, exhaustion, loss of appetites, cough and sometimes a blocked nose and sore throat. It may last a week or more and possible complications include pneumonia. Most cold don’t last long and need no specific treatment other than painkillers and simple measures such as decongestant rubs or vaporizers. Antibiotics are of no benefit. Zinc supplements may help to settle a cold more quickly. Children with flu can be given similar treatments, with lots of rest, medicine to bring down any fever and plenty of fluids to avoid dehydration. Lowering the temperature in the room can also be helpful when someone has a fever. Specific antiviral treatments for flu are now available, but generally these are only given to those at high risk of flu complications.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 36 to 42.
Whales are the largest animals in the world, and the gentlest creatures we know. Although the whale is very huge, it is not hindered at all by its size when it is in the water. Whales have tails that end like flippers. With just a gentle flick, it can propel itself forward. The skin of a whale is so smooth that it does not create any friction that can slow the whale down. A whale’s breathing hole is located on the top of its head, so it can breathe without having to completely push its head out of the water. Whales are protected from the cold seawater by body fat that is called blubber.
Whales live in the ocean but, in terms of behaviours, they are more similar to humans than fish. They live in family groups and they even travel in groups when they have to migrate from cooler to warmer waters. The young stay with their parents for as long as fifteen years. Whales are known not to desert the ill or injured members; instead, they cradle them.
When whales are in danger, there are people who go to great lengths to help them. One such case occurred in 1988, when three young whales were trapped in the sea. It was close to winter and the sea had begun to freeze over. Whales are mammals that require oxygen from the air, so the frozen ice was a great danger to them. All they had then was a tiny hole in the ice for them to breathe through. Volunteers from all over soon turned up to help these creatures. They cut holes in the ice to provide more breathing holes for the whales. These holes would also serve as guides for the whales so that they could swim to warmer waters.
(Adapted from http://www.englishdaily626.com?reading_comprehension)
According to the passage, why was the frozen ice on the sea surface a danger to whales?
A. Because they couldn’t swim in icy cold water.
B. Because they couldn’t eat when the weather was too cold.
C. Because whales couldn’t breathe without sufficient oxygen.
D. Because the water was too cold for them as they were warm-blooded.
Đáp án C
Because whales couldn’t breathe without sufficient oxygen.
“Whales are mammals that require oxygen from the air, so the frozen ice was a great danger to them.” Dịch: cá voi là động vật có vú, chúng cần oxy từ không khí để sống, do đó băng là mối đe dọa đối với chúng.

In Britain, the climate is not very good. There are very few hot days and it rains a lot. Because of this, people spend a lot of time at home. Generally, British homes have a lot of furniture in them, carpets on the floors and heavy curtains. Many houses in Britain are old. Many of them are over one hundred years old. Often, they do not have enough insulation and the heat goes out through the windows, the doors and up the chimney. Because of the climate, people in Britain have to spend a lot of money on heating. Many houses have a special system called "central heating". This heats all the rooms and, at the same time, heats the hot water. Houses without central heating often have gas, electric or coal fires. The rooms in most British houses are quite small. New houses are much better. They have two layers of glass in the windows to stop the heat going out.

2. Are there a few hot days in Britain ?
