Hence the great interest in animal-to-human transplants, known as xenografts or xenotransplants (from the Greek work xenos, meaning strange of foreign) (56) most scientists believe is the only long-term solution to the organ (57) . There have been attempts at xenotransplants (58) the beginning of this century but neither has been successful; the longest (59) was a 20-day-old baby called Fae, who in 1984 was (60) the heart of a baboon.
The main (61) with any organ transplant is that the immune system of the patient receiving the organ sees the transplant organ (62) an invader. The immune system therefore launches a massive attack on the invader, activating enzymes knows as complement, which attack the (63) body, eventually killing the patient as well. This rejection has been (64) when transplanting human organs between humans by the close matching of tissue and the long-term use of drugs known as immuno-suppressants, first introduced just over ten years ago. With xenotranplants, however, rejection is even more (65) ; a normal pig's heart, for example, transfuses with human blood can be destroyed in 15 minutes.

How things have changed. Nuclear power is back in favor, thanks to fears about oil supplies, energy security and global warming. France is ready to develop its expertise into a significant export. Its president, Nicolas Sarkozy, considers the sale of nuclear power to be central to his diplomacy: it is a symbol of France's technical power and a reaffirmation of its status as a global industrial power. Soon after his election 18 months ago, he toured countries from China to Libya to tout France's nuclear expertise, signing deals to open the way for French firms to sell reactors.
France has two competitive advantages in the field. First, it has the most recent and extensive experience of any country in building and operating nuclear plants. That has given Areva's "third generation" reactor design, called the EPR, an advantage over blueprints from its two big rivals: Westinghouse, now a unit of Toshiba of Japan, and GE Hitachi, a recently formed joint venture(合资企业). Second, French engineers have developed a new reprocessing technique, so that nuclear energy produces less waste than in other countries.
Areva's EPRs are under construction at Flamanville in Normandy, Olkiluoto in Finland and Taishan in China. Areva forecasts that demand for nuclear capacity could bring it orders for 60 reactors, or one-third of the total market, by 2020 -- each with a price of around 5 billion. Westinghouse has orders from China for four of its new AP1000 reactors, and GE Hitachi's ESBWR design is being considered by several American utilities.
The high cost of building new plants, arid the uncertainty over the cost of nuclear energy relative to other sources, could delay the nuclear renaissance (复兴), especially in the midst of a credit crunch. Luckily for sellers, governments are bent on tackling climate change and securing energy supplies, and are likely to offer big subsidies.
Britain, for one, has given its blessing to France's nuclear ambitions: in September Electricit6 de France (EDF), a state-owned energy giant which owns and runs France's plants (and is thus closely intertwined with Areva), bought British Energy, a troubled utility in which the British government held a big share.
What does the author tell us about Areva in the passage?
A．It is a French company, used to be owned by. private sector.
B．It has stepped into the third-generation .reactor design period.
C．Its third generation reactor has been constructed in France, Finland and China.
D．Its nuclear capacity will occupy one-third of the total in less than a decade.
B．wasn't there
C．used there
D．usedn't there
A．Monosemy
B．Polysemy
C．Antonymy
D．Synonymy
