8 . A giant dam was built many years ago to control the Colorado River in the U.S. This dam was built to protect the land and houses around the river.
This huge dam is in the Black Canyon. It is possible to drive a car from one side of the river to the other on a road, which is on the top of the dam. This dam is so big that there is an elevator inside. The elevator goes down forty-four stories from the road to the bottom. There is enough concrete in this dam to build a highway from New York to San Francisco. Thousands of people worked on this dam for five years.
This huge dam was called Boulder Dam when it was finished in 1936.Later it was renamed Hoover Dam in honor of a president of the United States. Hoover Dam, one of the highest dams in the world, is situated between the states of Arizona and Nevada.
Q:Hoover Dam lies ______.
A.between Arizona and Nevada |
B.in the Black Canyon |
C.between New York and San Francisco |
D.both A and B |
9 . DNA analysis has revealed family relationships between more than 10 generations of Stone Age people at megalithic(巨石的) tombs in Ireland and Sweden.
The evidence suggests that megaliths, prehistoric large stone structures, sometimes acted as graves for family groups in northwestern Europe thousands of years ago. The latest findings throw new light on the origins and social structure of the groups that built megaliths in this region—a history that has long been hidden in mystery.
For their study, the international team of researchers analyzed the genomes—the complete set of genetic material in a cell—of 24 Stone Age individuals from five megalithic burial sites in lreland, Scotland and Gotland, a large Swedish island in the Baltic Sea.
This analysis showed that many of the individuals buried at each megalith, who all lived between 3,800 B.C. and 2,600 B.C., according to radiocarbon-dating of their remains, were closely related via family ties.
The results also showed that the individuals buried at the megaliths were related to Neolithic(新石器时代的) farmers in northern and western Europe but genetically distinct from other hunter-gatherers. This was particularly noticeable at the Ansarve site on the island of Gotland.
“The people buried in the Ansarve tomb are remarkably different on a genetic level compared to the individuals dug out from hunter-gather contexts, showing that the burial tradition in this megalithic tomb, which lasted for over 700 years, was performed by distinct groups with roots in the European Neolithic expansion,” Magdalena Fraser, co-first author from Uppsala University, said in the statement
