阅读理解。

All the Lortons' farm animals - the cows and the goats, the ducks and the chickens, got along well

with Roger-a llama (美洲驼). But since llamas are used to thinking of animals like coyotes(土狼) and

dogs as threats, it took Roger a few weeks to accept the family dog.

Roger protects the sheep and lambs in two ways. First, he keeps the sheep together. A hungry

coyote will try to scatter(分散) the flock and then pick off a weak or small animal that has become

separated from the rest. But when a coyote threatens the Lorton's sheep, they all run to Roger,

depending on him to defend them.

And he does, with his second defense: confronting(对抗) the coyote. Llamas are very curious and

will run at top speed to investigate anything that looks interesting. When a coyote sees a

three-hundred-pound llama rushing toward it, the coyote will not usually wait around to see what the

llama wants.

And once a llama realizes that a coyote is threatening the flock, the llama will stand between the

coyote and the sheep to defend them. Often, the llama will charge toward the coyote with its head

down. As it runs, it will sometimes call out an alarm to the flock in a high-pitched voice. Since Roger's

arrival, coyotes haven't gotten any sheep from the Lortons.

1. The purpose of the passage is to tell us that _____.

A. a llama helps guard sheep

B. coyotes are sheep's main enemy

C. llamas are much smarter than coyotes

D. some types of dogs can't protect sheep

2. The following words can be used to describe Roger Except________.

In the early 1990s, following the Clapham Junction rail crash in December 1988,and two other fatal accidents in early 1989 caused by SPADs, British Rail was keen to implement the ATP system across the entire British railway system. However, the cost (estimated at over £1bn) was balked at by the Conservative government, whose priority was the privatization of the railways.

This requirement is in response to the Ladbroke Grove rail crash. All Chiltern Railways Class 165 and Class 168 trains are also fitted with ATP. Also, all of Heathrow Express Class 332 trains and Heathrow Connect’s Class 360/2 trains are fitted with this system.
