The operation lasted 12 hours and needed two teams, one for the father and one for the daughter.47 In these cases, the donor's liver grows to normal size in about eight weeks and the child's liver becomes smaller.
Lani spent three weeks in hospital after the operation. Because the receiver's body tries to reject the new organ, the patient has to be given special drugs. 48 Although David left hospital after 10 days, he didn't return to work until after three months. In order to reach the liver, the doctors have to cut through the stomach wall, which is strong and full of muscle. It therefore takes a long time to recover after this operation. 49
So far, only 16 of these liver-transplant operations have been carried out in Britain. 50 Doctors say, “If possible, we prefer to take a liver from a dead donor, usually a parent.”
Lani still has to look after her health, and she gets more tired than other children of the same age, but doctors hope that she will continue to get stronger and stronger. A She had one operation when she was six weeks old, which was not successful.
B While these drugs are given, it is important that the patient does not catch any illness, not even a cold.
C In this operation a piece of liver, weighing about 250--300 grams, was removed from the father and transplanted into the daughter.
D David quickly recovered from the operation.
E However, they are more common in North America and Japan. F David was finally able to ride his bike again after about a year. 第六部分：完型填空(第51～65题，每题1分，共15分)

Crashed Cars to Text Message for Help
There is no good place to have a car crash--but some places are worse than others. In a foreign country, for instance, 51 to explain via cell-phone that you are upside down in a ditch when you cannot speak the local language can fatally delay the arrival of the emergency services.
But an answer may be at hand. Researchers funded by the European
Commission are beginning tests of a system called E-merge that 52 senses when a car has crashed and sends a text message telling emergency services in the local language that the accident has taken place.
The system was 53 by ERTICO, a transport research organization based in Brussels, Belgium. Cars are fitted with a cell-phone-sized device attached 54 the underside of the dashboard which is activated by the same sensor that triggers the
airbag in a crash. The device 55 a cell-phone circuit, a GPS positioning unit, and a microphone and loudspeaker.
It registers the severity of the crash by 56 the deceleration data from the airbag's sensor, Using GPS information, it works out which country the car is in, and from this it determines 57 which language ot compose an alert message detailing precise location of the accident.
The device then automatically makes a call to the local emergency services 58 If the car's occupants are conscious, they can communicate with the operator 59 the speaker and microphone.
E-merge also transmits the vehicles make, model, color and license number, and its heading when it crashed, which in turn indicates on which side of a multi-lane highway it ended up.
This 60 the emergency services find the vehicle as soon as they arrive on the scene, “We can waste a large 61 time searching for an incident,” says Jim Hammond, a (an) 62 in vehicle technology at the Association of Chief Police Officers in the UK. Tests will begin soon with police car fleets in the UK. Trials have already started in Germany, Sweden, Spain, the Netherlands and Italy.
In-car systems that summon the emergency services after a crash have 63 been fitted in some premium cars. ERTICO says that 64 EU states are willing to fund the necessary infrastructure; E-merge could be working by 2008.
A study by French car maker Renault concluded that the system could save up to 6000 fo the 40,000 lives lost each year on Europe's roads, and prevent a similar number of serious in-juries.
The Renault study estimates that fitting E-merge to every car in Europe would eventually save around 150 billion per 65 in terms of reduced costs to health services and insurance companies, and fewer lost working days. 51 A try
