Giant Structures It is an impossible task to select the most amazing wonders of the modern world since every year more (51) constructions appear. Here are three giant structures which are worthy of our admiration (52) they may have been surpassed by some more recent wonders. The Petronas Twin Towers The Petronas Towers were the tallest buildings in the world when they were completed in 1999. (53) a height of 452 metres, the tall twin towers, like two thin pencils, dominate the city of Kuala Lumpur. At the 41st floor, the towers are (54) by a bridge, symbolizing a gateway to the city. The American architect Cesar Pelli designed the skyscrapers. Constructed of high-strength concrete, the building (55) around 1,800 square metres of office space on every floor. And it has a shopping centre and a concert hall at the base. Other (56) of this impressive building include double-decker lifts, and glass and steel sunshades. The Millau Bridge The Millau Bridge was opened in 2004 in the Tarn Valley, in southern France. At the (57) it was built, it was the world’s highest bridge, (58) over 340m at the highest point. The bridge is described as one of the most amazingly beautiful bridges in the world. It was built to (59) Millau’s congestion problems. The congestion was then caused by traffic passing from Paris to Barcelona in Spain. The bridge was built to withstand the (60) extreme seismic and climatic conditions. Besides, it is guaranteed for 120 years! The Itaipu Dam The Itaipu hydroelectric power plant is one of the largest constructions of its kind in the world. It (61) of a series of dams across the River Parana, (62) forms a natural border between Brazil and Paraguay. Started in 1975 and taking 16 years to complete, the construction was carried out as a joint project between the two (63) . The dam is well-known for both its electricity output and its size. In 1995 it produced 78% of Paraguay’s and 25% of Brazil’s (64) needs. In its construction, the amount of iron and steel used was equivalent to over 300 Eiffel Towers. It is a (65) amazing wonder of engineering.

Future Computer Trends:
The components of a PC will be built into the (6) and large plasma or electroluminescent flat panel display hanging on a partition wall will act as both a (7) and videophone display.
A high resolution, touch sensitive LCD (8) into desktop will allow pan-based pointing and data input. In the home, meanwhile, computers will become as ubiquitous as TVs.
Computer interfaces will be far friendlier than (9) graphical user interfaces (GUI) of today. Computers will use "human interfaces" based on multimedia.
RISC microprocessors will finally obliterate the ever thinning gap between workstations and PCs. Similar advances in nonvolatile flash memory will lead to the replacement of magnetic (10) disks with electronic "silicon disks".

Part of the inside of the car is (5) so that the designers can sit in it. They can feel if there is enough (6) inside and if they can reach (7) .

Again, computers are used to make sure that all the parts are (10) as they are needed. The factory usually stays open all through the night so that the car production never stops.
