听力原文: This is your local weather update with meteorologist Chris Lee. We can look forward to a beautiful evening, with warm temperatures and a lovely sunset. Sunset will occur at 8:30, and the beach is the perfect place to watch it. It's better to stay on shore, though. There is a fog warning out for small boats tonight. A light fog will roll in just after sunset and stay with us all night. The sun rises tomorrow morning at 5:45. Light winds in the morning will blow the fog out to sea, so we'll enjoy sunshine and more warm temperatures tomorrow afternoon. Take advantage of the nice weather now because rain is predicted for later in the week.
What time will the sun set tonight?
A. 5:00.
B. 5:45.
C. 8:00.
D. 8:30.
听力原文:Woman: I think we've got the transportation plan worked out. We have four buses to take people from the hotel to the convention center. That should be enough, don't you think?
Man: Yes, I think so. It takes five minutes to load one bus and ten minutes to make the trip, so we could plan to have one bus leave every fifteen minutes.
Woman: That sounds like a good schedule. Each bus could make the round trip in thirty minutes, and no one would have to wait too long for a ride. Then we won't have to worry about anybody's ruffled feelings.
How many buses are there?
A. One.
B. Two.
C. Three.
D. Four.
What weather is expected this afternoon
A. Rain.
B. Stormy winds.
Cool breezes.
Dry and windless.
