Puerto Rico may be part of the USA but its music and dance is a mixture of both Spanish and American rhythms. The country, as a result, is a mixture of very new and very old. It exhibits the open American way of life yet remains the more formal Spanish influences. This is reflected in the architecture, not just the difference between the old and the modern in urban areas but also in the countryside, where older buildings sit side by side with schools and houses. It is found in the cooking, too many fast food restaurants together with local cooking which has its roots in the mixture of culture of all the Caribbean and in the music, where rock music is played in beach resorts but in the hilly center, Puerto Rican music can be heard. Old volcanic mountains, long motionless, take up a large part of the center, with the highest peak, Corrode Punta, at 1338 meters in the Cordillera Central.

We like to consider ourselves the superior race, and we are. It’s true that we are getting to know more and more, and we actually live in “the information age”. Our human vanity(虚荣心) makes us believe that we really have to know everything! Surprisingly, we do not have this ability. The question “what is happening in the Bermuda Triangle” is the very proof.
Where is the Bermuda Triangle located? The mysterious triangle is believed to be situated between Florida, Bermuda and Puerto Rico, where too many unusual events have happened.
On December the 5th 1945, five U.S. military planes took off from Florida on a clear day only to disappear over Bermuda. Furthermore, some other disappearances took place; in 1947, an American C54 plane simply disappeared at 100 miles from Bermuda; at 80 miles, a Star Tiger plane disappeared in 1948.
Even Columbus had trouble in Bermuda. Some of his journals were about the strange happenings there: “the waters are changing their colors” and “compasses are going wild”.
Maybe it’s why it is called the Devil’s triangle or the Atlantic cemetery.
Many hypotheses were stated in order to explain the strange events. In spite of these attempts, the mystery of the Bermuda Triangle remains unsolved.
Some people get to say that maybe aliens are involved in it. Other imaginative scientists relate the happenings in Bermuda to Einstein’s theory, saying that the missing ships and planes are translated to another dimension of space and time and taken into another world.
Maybe we will just have to wait to go to Heaven and ask the One who made it. The answer will surely be a satisfying one!

The green turtle is listed as endangered by the International Union for the Conservation of Nature. Under the U．S. Endangered Species Act of 1973, the green turtle was listed as threatened except for the breeding populations in Florida and on the Pacific coast of Mexico, where it is listed as endangered.
Green turtles continue to be caught for money by humans, and the destruction and loss of nesting and foraging(觅食)sites is a serious problem. Humans have already caused the decrease of large green turtle populations, including those that once nested in Bermuda and Cayman Islands. The situation of green turtle populations is difficult to determine because of our lack of knowledge about their life cycles. The number of nests in Florida appears to be increasing, but we don’t know whether this is due to an increase in the number of nests or because we have started to monitor(监控)nesting beaches more closely.
The green turtle is the largest hardshelled sea turtle. Adults of this species commonly reach 100 cm in length and 150 kg in mass. The average size of a female nesting in Florida is 101.5 cm straight in length, with an average body mass of 136 kg.
Growth rates of green turtles have not been measured under natural conditions. Green turtles grow slowly.
In the southern Bahamas, green turtles grow from 30 to 75 cm in 17 years, and according to Bjorndal and Bolten, growth rates decrease with increasing length. Growth rates measured in green turtles from Florida and Puerto Rico fall within the range of growth rates measured in the southern Bahamas. Based on growth rate studies of wild green turtles, the researchers Balazs, Frazer and Ehrhart estimate the age of sexual maturity(成熟)can range anywhere from 20 to 50 years.

| D．can grow from 30 to 75 cm in 17 years in southern Florida |
| A．Because it is difficult for us to be close to them. |
| B．Because we have limited knowledge about them. |
| C．Because we haven’t measured their growth rates. |
| D．Because they grow too slowly. |
