Có thể suy ra từ bài đọc rằng điều gì là mối nguy hiểm lớn nhất đối với thợ lặn?
Pressurized helium: Khí Heli nén
Nitrogen diffusion: Sự khuếch tán khí Nitơ
An air embolism: Sự thuyên tắc hơi
Nitrogen bubbles: Bóng khí Nitơ
Thông tin ở đoạn cuối, dòng thứ nhất. “During ascent from a depth of 10 meters, the volume of air in the lung will double because the air pressure at the surface is only half of what it was at 10 meters. This change in volume may cause the lungs to distend and even rupture. This condition is called air embolism.” (Trong quá trình nồi lên từ độ sâu 10 mét, lượng không khí trong phổi sẽ tăng lên gấp đôi vì áp lực khí tại bề mặt nước chỉ còn 1 nửa so với ở độ sâu 10 mét. Sự thay đổi về lượng khí có thể làm phổi sưng phồng, thậm chí là vỡ nát. Hiện tượng này gọi là thuyên tắc hơi.)

A recent study shows that an unequal share of household chores is still the norm in many households, despite the fact that many more women now have jobs. In a survey of 1,256 people ages between 18 and 65, men said they contributed an average of 37% of the total housework, while the women estimated their share to be nearly double that, at 70%. This ratio was not affected by whether the woman was working or not. When they were asked what they thought was a fair division of labour, women with jobs felt that housework should be shared equally between male and female partners. Women who did not work outside the home were satisfied to perform 80% - the majority of the household work - if their husbands did remainder. Research has shown that, if levels increase beyond these percentages, women become unhappy and anxious, and feel they are unimportant. After marriage, a woman is reported to increase her household workload by 14 hours per week, but for men the amount is just 90 minutes. So the division of labour becomes unbalanced, as a man's share increases much less than the woman's. It is the inequality and loss of respect, not the actual number of hours, which leads to anxiety and depression. The research describes housework as thankless and unfulfilling. Activities included in the study were cooking, cleaning, shopping, doing laundry, washing up and childcare. Women who have jobs report that they feel overworked by these chores in addition to their professional duties. In contrast, full-time homemakers frequently anticipate going back to work when the children grow up. Distress for this group is caused by losing the teamwork in the marriage.
According to the passage, a fair division of labour is that ...................

The biological community changes again as one moves from the city to the suburbs. Around all cities is a biome called the "suburban forest". The trees of this forest are species that are favored by man, and most of them have been deliberately planted. Mammals such as rabbits, skunks, and opossums have moved in from the surrounding countryside. Raccoons have become experts at opening garbage cans, and in some places even deer wander suburban thoroughfares. Several species of squirrel get along nicely in suburbia, but usually only one species is predominant in any given suburb -fox squirrels in one place, red squirrels in another, gray squirrels in a third - for reasons that are little understood. The diversity of birds in the suburbs is great, and in the South, lizards thrive in gardens and even houses. Of course, insects are always present. There is an odd biological sameness in these suburban communities. True, the palms of Los Angeles are missing from the suburbs of Boston, and there are species of insects in Miami not found in Seattle. But over wide stretches of the United States, ecological conditions in suburban biomes vary much less than do those of natural biome. And unlike the natural biomes, the urban and suburban communities exist in spite of, not because of, the climate

Music can bring us to tears or to our feet, drive us into battle or lull us to sleep. Music is indeed remarkable in its power over all humankind, and perhaps for that very reason, no human culture on earth has ever lived without it. From discoveries made in France and Slovenia, even Neanderthal man, as long as 53,000 years ago, had developed surprisingly sophisticated, sweet- sounding flutes carved from animal bones. It is perhaps then, no accident that music should strike such a chord with the limbic system – an ancient part of our brain, evolutionarily speaking, and one that we share with much of the animal kingdom. Some researchers even propose that music came into this world long before the human race ever did. For example, the fact that whale and human music have so much in common even though our evolutionary paths have not intersected for nearly 60 million years suggests that music may predate humans. They assert that rather than being the inventors of music, we are latecomers to the musical scene. Humpback whale composers employ many of the same tricks that human songwriters do. In addition to using similar rhythms, humpbacks keep musical phrases to a few seconds, creating themes out of several phrases before singing the next one. Whale songs in general are no longer than symphony movements, perhaps because they have a similar attention span. Even though they can sing over a range of seven octaves, the whales typically sing in key, spreading adjacent notes no farther apart than a scale. They mix percussive and pure tones in pretty much the same ratios as human composers – and follow their ABA form, in which a theme is presented, elaborated on and then revisited in a slightly modified form. Perhaps most amazing, humpback whale songs include repeating refrains that rhyme. It has been suggested that whales might use rhymes for exactly the same reasons that we do: as devices to help them remember. Whale songs can also be rather catchy. When a few humpbacks from the Indian Ocean strayed into the Pacific, some of the whales they met there quickly changed their tunes – singing the new whales’ songs within three short years. Some scientists are even tempted to speculate that a universal music awaits discovery.

In the United States, it is important to be on time, or punctual, for an appointment, a class, a meeting, etc... This may not be true in some other countries, however. An American professor discovered this difference while teaching a class in a Brazilian university. The twohour class was scheduled to begin at 10 a.m, and end at 12 a.m. On the first day, when the professor arrived on time, no one was in the classroom. Many students came after 11 a.m. Although all of the students greeted the professor as they arrived, few apologised for their lateness. Were these students being rude? He decided to study the students’ behavior. In American university, students are expected to arrive at the appointed hour. On the other hand, in Brazil, neither the teacher nor the students always arrive at the appointed hour. Classes not only begin at the scheduled time in the United States, but they also end at the scheduled time. In the Brazilian class, only a few students left the class at noon, many remained past 12:30 to discuss the class and ask more questions. While arriving late may not be important in Brazil, neither is staying late. The explanation for these differences is complicated. People from Brazilian and North American cultures have different feelings about lateness. In Brazil, the students believe that a person who usually arrives late is probably more successful than a person who is always on time. In fact, Brazilians expect a person with status or prestige to arrive late, while in the United States, lateness is usually considered to be disrespectful and unacceptable. Consequently, if a Brazilian is late for an appointment with a North America, the American may misinterpret the reason for the lateness and become angry. As a result for his study, the professor learned that the Brazilian students were not being disrespectful to him. Instead, they were simply behaving the appropriate way for a Brazilian student in Brazil. Eventually, the professor was able to adapt his own behavior to feel comfortable in the new culture.
