1. 现在完成进行时的概念
现在完成进行时表示动作从过去某一时间开始一直持续到现在, 这个动作可能终止,可能还在进行。
2. 现在完成进行时的形式
have / has been doing
3. 现在完成时和现在完成进行时的区别
1）在不用时间状语的情况下，现在完成进行时的动作不一定已经完成，很可能持续下去，而现在完成时一般表示动作已经完成。即现在完成进行时强调动作的延续性，而现在完成时强调动作的结果。
a. I have been designing solar racing cars. 我一直在设计太阳能赛车。
b. I have designed five or six different cars. 我已经设计了五六辆不同的小汽车了。
2）现在完成进行时往往表示动作在重复，而现在完成时一般不表示动作的重复。
a. I have been taking part in races for four years. 我四年来一直在参加比赛。
b. How many races have you taken part in 你参加了多少场比赛了？
3）现在完成进行时与所有进行时态一样带有感彩，可使表达显得生动，而现在完成时往往只表明一个事实、一种影响或结果，不带感彩。
a. What have you been doing You looked fed up. 你一直在干什么呀？你看上去很不高兴。
b. I have finished my homework. 我已经完成了作业。
4. 常与现在完成进行时连用的时间状语
现在完成进行时常与表示一段时间的状语连用，例如：all the time, this week, all night, these few days, for …, since … 等。
a. A private detective has been tailing him for several weeks. 一个私人侦探几星期以来一直跟踪他。
b. Craig loves outdoor activities — he skis in winter and has been fishing and hunting since he was a child. Craig 热爱户外活动, 冬天他去滑雪，他从小就开始钓鱼和打猎。

Busy traffic doesn't stop creatures like deer and bears from crossing highways. And, sadly, they may lose their lives. In just two years along a part of a highway in Utah, USA, 98 deer, three moose, two elk, two raccoons, and a cougar were killed in car collisions (碰撞) — a total of 106 animals. People are also hurt. About 200 die every year in the more than one million wildlife vehicle collisions in the country. “Over the last 15 years, such collisions have increased by 50 percent,” says Rob Ament at the Western Transportation Institute (WTI).
There's one effective solution, however: wildlife underpasses and overpasses. “You can get reductions of 85 to 95 percent with crossings under or over highways,” Ament says. These bridges and tunnels are showing up worldwide. In Washington State, along a 15-mile stretch of highway on I-90, there are 20 wildlife bridges and six underpasses. They allow many creatures to cross the road.
These wildlife crossings aren't just about saving animals from accidents. I-90 is an important east-west lifeline in the state. But it prevents many animals from moving between north and south. They have to produce their young among closely related members. This is really a big problem. “Dying out happens when populations can't find each other. This is especially true for species in old-growth forests,” says wildlife biologist Patty Garvey-Darda.
One of the most successful examples of wildlife overpasses is in Banff, Canada. Tony Clevenger is a wildlife biologist at WTI. He has been monitoring wildlife at Banff 's six overpasses (and 38 underpasses) for years. “Grizzly bears, elk, deer, and moose favor big, open structures,” he says. “Cougars and black bears use smaller crossings, with less light and more cover.” Black bears' natural home is in the forest, so they won't feel comfortable on a large, open crossing structure, for example.
“So on one side we should plant trees, and on the other side have areas that are open, planted with grass,” Clevenger says.
1. What do the numbers in paragraph 1 show
A. The new problem faced by drivers.
B. The danger from loud noise on highways.
C. The serious problem of wildlife vehicle accidents.
D. The growing number of collisions on highways in Utah.
2. Which best describes Rob Ament's attitude to wildlife passes
A. Doubtful. B. Supportive. C. Worried. D. Mad.
3. Why are wildlife crossings important for animals according to Patty Garvey-Darda
A. They are about species survival.
B. They can connect different species.
C. They allow species to find enough food.
D. They help control the number of species.
4. What has Tony Clevenger found
A. Banff 's overpasses and underpasses are successful.
B. More wildlife crossings are needed in Banff.
C. Different animals prefer different crossings.
D. Many animals feel unsafe on the crossings.
III. 完形填空
