【推荐3】People realize that,     1     animals may not have the same intelligence as human beings, they are smart enough to learn certain things.

Dogs are     2     (extreme) useful as companions for blind people. When a dog has been properly trained, he will always lead his master     3     the right direction and keep him out of danger.

Horses are also able to learn many things. Horses that are used for guard or police duty must learn never to     4     (frighten) of noises, traffic, and other disturbances. Racing horses are also quite strong. Therefore, it is necessary for those people     5     train them to be very patient and understanding.

The moving pictures and television can use     6     (train) animals too. Some animals, such as monkeys and foxes, are easy to film.     7     you have to do is make a trail in front of the camera by dragging something that smells good to     8     animals over the ground. Big animals, such as lions and tigers, can be photographed as they bound happily back to     9     families and dinner. If a movie actor is nearby, the well-trained animal will pay no attention to him.     10    , the audience may imagine that the actor escaped a terrible death by the skin of his teeth.

New Yorkers were shocked in early December when a creature as big as a school bus     1     (surface) from the Hudson River. Over the next three days,    2     humpback whale (座头鲸) swam by several popular tourist destinations, where a journalist took    3    (photo) of the animal seemingly waving its tail at Lady Liberty.

Scientists say NYC0089, which hasn't been spotted in several weeks, has likely returned to deeper waters south of the Hudson. Still, the     4    (frequent) of whale sightings in the broader area has gone up rapidly in recent years.

“With these numbers increasing     5     (sharp), it's not surprising that you're seeing them in some unusual places,” says Brown — a biologist. Including the Hudson River and Staten Island.

Scientists say the     6    (rise) whale sightings are likely related to purer water and a brimming buffet of Atlantic menhaden, a fish favored by humpbacks, resulting     7     landmark environmental regulations     8    (pass) in the 1970s as well as New York city cleanup efforts.

“Seeing more whales in this area is a sign    9     the waters are cleaner and there's more food here for these whales,” Brown says. “It shows     10     we've been doing is working, so we need to keep doing that — and more — to protect these species.”

Climate varies from place to place. A desert, for example, is known as a dry climate     1     little water falls during the year. In polar regions, however,     2    (rise) global temperatures mean that ice sheets and glaciers are melting at an alarming rate from season to season. This contributes     3     sea level rise in     4    (variety) regions of the planet.

The cause of current climate change is larger human activities, like burning fossil fuels, such as natural gas, oil and coal. Burning these materials     5    (give) off greenhouse gases into the Earth's atmosphere. It is these greenhouse gases     6     cause the Earth's average temperature to rise. The warming of the planet has     7    (effect) on the local and regional climates. Throughout the Earth's history, climate has     8    (continual) changed. When occurring naturally, this is     9     slow process that has taken place over hundreds or thousands of years. The human-influenced climate change that is happening now is occurring at a much     10    (fast) rate.
