There are many islands south of Florida. One of them is Hispaniola. Its name points to the fact that Christopher Columbus visited the island in 1492. As a result, Spain ruled(统治) the island for the next 300 years. Two nations now share the island. Haiti takes up one third(三分之一) of the island in the west and the Dominican Republic takes up the two thirds in the east.
The Dominican Republic's area is about 18，000 square miles with a population(人口) of about 8 million. Most people live close to the island's coast. Like many other tropical(热带的) islands, the Dominican Republic thinks of tourism as a key industry(行业). The cities on the coast, especially, depend on tourists to fill their hotels and restaurants. Dominicans and tourists all love the beautiful beaches and forests.
When you're ready for something else, walk into town. Music, dancing, and people in colourful masks will greet you at nearly every street corner. Whether you go to join them or get away from them, there will be a place for you in the Dominican Republic.

Scientists looked for paw prints(爪印) in the bamboo forests. In this way, they knew the number of pandas! “It's hard to see pandas in nature，” said Colby, a scientist. “They hide in the thick bamboo forests.” That's why scientists used paw prints to get the number.
“We found pandas living in areas we didn't know about，” said Colby.
Here are some fun facts about pandas.
*It takes a panda more than 10 hours to eat 9 kg to 14 kg of bamboo every day.
*A newborn panda weighs 20 40 grams. That is about the weight of a small apple.
*A panda's front paws have wrist bones. The panda uses them to catch bamboo.
The main danger to pandas is that their land is becoming smaller and smaller. Pandas lose their land when people cut down the forests for wood and farming. Now, China has 13 nature reserves. People mustn't cut down trees there. Scientists want to set up more nature reserves to give pandas a better place to live.
( )1．How did scientists know the number of pandas
A．By catching pandas.
B．By using a small camera.
C．By looking for paw prints.
D．By taking a walk in the forests.
( )2．Which of the following is TRUE
A．A newborn panda weighs over 200 grams.
B．A panda uses its front paws to catch bamboo.
C．There are fewer and fewer nature reserves in China.
D．A panda usually sleeps more than 10 hours every day.
( )3．What does the last paragraph mainly talk about
A．The number of the pandas.
B．Fewer and fewer trees in China.
C．The pandas in the nature reserves.
D.The big problem the pandas are facing.
( )4．文章出处In which part of a magazine can you probably read the text
A．Health. B．Animals.

①By watching whales closely and listening carefully to their sounds, scientists discovered that the “songs” are a way for whales to communicate with each other far away.
②It's amazing because it proves that animals have their own ways of communicating.
Step 4
A Wonderful Discovery in Nature
Nature is full of amazing secrets, and here's a wonderful discovery.
The discovery is that some whales sing long, low sounds while swimming. For hundreds of years, people wondered if these sounds were songs, until scientists made this amazing discovery.
By watching whales closely and listening carefully to their sounds, scientists discovered that the “songs” are a way for whales to communicate with each other far away. It's amazing because it proves that animals have their own ways of communicating.
This discovery teaches me that if we observe nature patiently, we can discover more wonderful secrets about the world around us.
四、A Cool Discovery in Insect Exploration
Here's a cool discovery in insect exploration that's full of fun. A certain type of small beetle can carry objects up to 20 times heavier than its own body.
This discovery was made by a group of middle school students. They observed the beetles in a park for two weeks, taking notes every day. It's important because it shows how small insects adapt to their environment, which helps us understand their behaviour better.
To make this discovery, the students needed to be patient. They watched the beetles quietly and didn't give up even when the insects hid. Their spirit tells us that careful and patient observation can help us discover interesting secrets of nature.第一课时　Starting out&Understanding ideas(Reading)

Last summer, I went to a nature camp. When I got off the bus, I saw a large rose field.
The smell of roses reminded me of my childhood. When I was little, my grandparents grew roses in the yard. I avoided going to their front yard all summer, because I had a fear of bees.
I asked a camp worker curiously(好奇地), “Why do people plant roses here？”
“For the bees，” she said with a smile.
Later that afternoon，Mr Poppy, the beekeeper(养蜂人) walked over.
“We're collecting honey today，” he said. “Would you like to help？”
“Me？” I asked.
He nodded kindly. “Don't worry. The bees are calm.”
He gave me a hat to protect my face. He said, “The bees stay calm if we move slowly.”
Then he opened the top of a hive(蜂箱) and blew some smoke inside. He lifted out a board from the hive.
“See They don't mind，” he said. “Want to try？”
I put on a glove nervously. I shut my eyes and held the board carefully. Holding__my__breath, I lifted the board slowly.
I opened my eyes to look at the board in my hands. I couldn't believe how perfect it looked. It was amazing. Then some bees moved along my arm calmly. And I was quite safe!
Mr Poppy gave me a piece of honeycomb(蜂窝). “Honey tastes best right from the honeycomb，” he said.
I tried some. The honey was sweet and warm, with a soft taste of rose. I closed my eyes and smiled.
( )1．Why did the writer avoid going to his grandparents' front yard all summer
A．Because he was afraid of bees.
B．Because he didn't like the smell of roses.
C．Because he didn't want to plant flowers.
D．Because he didn't enjoy playing outdoors.
( )2．What does the underlined phrase “Holding my breath” probably mean in Paragraph 12
A.The writer was too excited to breathe.
B.The writer felt nervous and tried to stay quiet.
C.The writer was out of breath after lifting the board.
D.The writer stopped breathing because of the bad smell.
( )3．How did the writer feel when he saw the board in his hands
A．Hopeful. B．Tired.
C．Amazed. D．Angry.
( )4．What did the writer learn from the experience
A．Helping others creates joy.
