听力原文: It's no secret that throughout history common stock has outperformed most financial instruments. If an investor plans to have an investment for a long period of time, then their portfolio should be comprised mostly of stocks ; however, investors who don't have this kind of time should diversify their portfolios. For this reason, the concept of "asset allocation" was developed. Asset allocation is an investment portfolio technique that aims to balance risk and create diversification by dividing assets among major categories. The underlying principle of asset allocation is that the older a person gets, the less risk he or she should face. After you retire you may have to depend on your savings as your only source of income.

28. Throughout history, what kind of stock has outperformed most financial instruments?

29.What is the purpose of asset allocation?

30.What is the principle underlying the concept of asset allocation?

Cairo, the cradle of civilization, the Melting Pot of Ancient and Modern Egyptian Civiliza
tions. It is the largest city in the Middle East and lies at the center of all routes leading to and from the three continents: Asia, Africa and Europe. It is the city where past and present meet. On its west side lies the Ancient Egyptian city of Memphis, and the site of the Pyramids, the only wonder surviving of the Seven Wonders of the World. Indeed, a journey through Cairo is a journey through time...

In spite of a thousand years of history, Cairo is young by Egyptian standards, because modern Cairo emerged only with the Arab conquest of Egypt.

The most famous of Cairo's sights is the string of 60 pyramids that stretches along the western border of the desert. Contrary to the common belief, only the Great Pyramid of Khufu, not all three Great Pyramids, is on the list of Wonders. The monument was built by the Egyptian pharaoh Khufu of the Fourth Dynasty around the year BC 2560 to serve as a tomb when he dies. When it was built, the Great pyramid was 145.75 m high. Over the years, it lost 10 m off its top. It ranked as the tallest structure on Earth for more than 43 centuries. Throughout their history, the pyramids have stimulated human imagination. When Napoleon invaded Egypt in 1798, his pride was expressed through his famous quote:" Soldiers! From the top of these Pyramids ,40 centuries are looking at us."

Cairo has been the most important arts center in the Islamic world for a thousand years. Cairo's long history and rich heritage are revealed in its many museums. The famous sights in this area are the Entomological Society Museum, with an excellent collection of Egyptian insects and birds. Also in the area is the museum housing the mysterious Sun Boat, only discovered in 1954 near the south side of the pyramid. The boat is believed to have been used to carry the body of Khufu in his last journey on earth before being buried inside the pyramid.

This is Cairo—radiant with a long and glorious past; adorned with the achievements of a distinguished present.

This is Cairo — a cradle of civilization, a wellspring of culture, and a meeting-place of the Asian, African, and European World.

This is Cairo-An international center for social economics, and political activity, which is making the noblest efforts aimed at peace among all nations and the benefits of all mankind.

Cairo is______.

A.the largest city in three continents

B.the financial center of the world

C.the' capital of Egypt

D.the youngest city in middle east
