     China_is_going_green. In order to reduce air pollution and oilshortages, automobile manufacturers

have announced their plans to develop hybrid vehicles (混合燃料汽车) for the Chinese market.

Toyota's hybrid car Prius will be ready to drive in China this week. Let's have a look at the new car.

     Any vehicle is a hybrid when it combines two or more sources of power. Hybrid cars run off a

rechargeable battery and gasoline. Hybrid cars have special engines, which are smaller than traditional

gasoline engines. They run at 99 percent of their power when the car is cruising (匀速行驶). A specially

designed battery motor provides extra power for running up hills or when extra acceleration is needed.

     Step into a Prius, and turn on the engine. The first thing you notice is how much quieter it is than a

traditional car. At this point, the car's gasoline engine is dormant (休眠). The electric motor will provide

power until the car reaches about 24 km/h. If you stay at a low speed, you are effectively driving an

electric car, with no gasoline being used, and no waste gas gives off.

     The onboard(车载的) computer makes the decision about when to use a gas engine, when to go

electric, and when to use a combination of the two. If you go over 24 km/h, when you step on the gas

pedal (油门), you are actually telling the computer how fast you want to go.

     The electronic motor recharges automatically using a set of batteries. When driving at high speed, the

gasoline engine not only powers the car, but also charges the batteries. Any time you use the brake, the

electric motor in the wheels will work like a generator and produce electricity to recharge the batteries.

     As a consequence, the car's batteries will last for around 200,000 miles.

下列关于长期肠外营养的并发症，不正确的是

A．胆石形成
B．可出现高血糖，甚至高渗性昏迷
C．肠道黏膜萎缩，细菌移位
D．高渗溶液刺激．易致中心静脉炎
E．可导致水电解质平衡紊乱

科学家们在完成序列精确测定的同时，还做了大量研究工作：对水稻第四号染色体所含基因进行预测分析，鉴定出4658个基因，为进一步鉴定这些基因的功能奠定了基础；完整地测定了水稻4号染色体的着丝粒序列，这是迄今首次完成的高等生物染色体着丝粒序列，为研究着丝粒的功能、染色体的稳定性和染色体的复制提供了基础，也为开发可转化的“人工水稻或植物染色体”提供了基础。 “大量的研究工作”是指( )。

A．开发了可转化的“人工水稻或植物染色体”

B．将鉴定出的这4658个基因注释在染色体的准确位置上

C．对水稻第四号染色体所含基因进行预测分析，鉴定出4658个基因；完整地测定了水稻4号染色体的着丝粒序列

D．完成高等生物染色体着丝粒序列，为研究着丝粒的功能、染色体的稳定性和染色体奠定了基础
