1.Brush your teeth the right way.

【題目】 Dolphins are not fish. They are mammals. They live in groups and speak to each other in their own language. But they aren't the same as almost all land animals. Their brains are as big as men's and they live a long life--- at least 20 or 30 years.

Like some animals, dolphins use some sounds to help them find their ways around. They also use sounds to talk to each other and to help them find food. They don't use their ears to receive sounds, but use the jaws(下顎).

It's strange that dolphins are friendly to man, and for thousands of years, there are many stories about dolphins and man. In the 19th century, in a dangerous part of the sea near New Zealand, there was a dolphin. The seamen liked him very much and gave him a very good name, Jack. From 1871 to 1903, Jack met every ship in the area and showed it the way. In 1903, a passenger on a ship with the name of " The Penguin" shot and hurt Jack. Luckily the dolphin didn't die, and after a long time he was well again. He guided the ships through the area for nine more years, but he refused to help the ship " The Penguin".

Today, some people still kill dolphins, but more people in the world protect them.

根據(jù)短文內(nèi)容，回答下列問題。

【1】Are dolphins fish or mammals?

__________________________________________________________

【2】What do dolphins use to receive sounds?

About five hundred years ago, an earthquake (地震) happened in a small village. Luckily for them, nothing was destroyed (毀壞) and no one was hurt. But a huge stone fell from a nearby mountain and stopped in the middle of the road.
When the earthquake stopped, many people came to the road and saw the stone. Some of the strongest men tried to lift the stone out of the road. But they couldn't move it. They tried to push it but failed. They tried to pull it with ropes but nothing worked.

【題目】Giving a Hand

Jaime, a new immigrant（移民）of the USA, was going to watch his daughter's first show in a school play. His daughter, Carol, was five years old. She was a student at the local public school. Carol did not have a very big role in the school play. She was just playing a rain cloud in a play about the drought in California. Carol had just one line. Her line was, "I am sad enough to cry about how dry the state is."

Jaime and his wife made sure to arrive early so that they could get a good seat to watch the show. They found seats in the front row. Before the show began, the schoolmaster made an introductory speech. The speech was about how hard the students and teachers worked together to make the play possible. At the end of the speech, the schoolmaster said, "Let's give the school staff a hand".

Jaime, whose English was not very good, stood up when the schoolmaster said this. He knew that when people said "to give someone a hand" they meant they needed help. Jaime always wanted to help, especially at his daughter's school. Jaime thought maybe they needed help backstage.

Jaime's wife put her arm in front of her husband. "Where are you going?" she asked in a low voice. "They need a hand," Jaime replied. His wife explained that "to give someone a hand" could also mean to applaud（鼓掌）someone. When you applaud someone you clap your hands（拍手）after their performance. You are not supposed to stand up and try to help others. "They don't need help. They just want us to clap," Jaime's wife explained. Jaime felt a little embarrassed. He sat back down and began clapping along with the rest of the audience.

Jaime thought to himself that someone needed to give the English language a hand. How could one phrase mean two different things? He meant the English language needed help.

【1】Why did Jaime and his wife arrive at the play early?

A.To talk to other parents.B.To wish their daughter good luck.

C.To get good seats to watch the show.D.To listen to the speech of the schoolmaster.

【2】Jaime thought "giving someone a hand" meant __________.

A.helping someoneB.clapping your hands

C.holding someone's handD.giving your hand to someone

【3】What can we learn from the passage?

A.Jaime stood up to applaud.B.Jaime is a warm-hearted man.

C.Jaime was better at English than his wife.D.Jaime's daughter played an important role in the show.
