Apple trees need a cold winter and a warm spring to grow well. In spring, apple trees have beautiful pink or white flowers. Bees fly from flower to flower. They help pollinate (授粉) the flowers. Without bees, there would be no apples. After pollination, the flowers slowly turn into small green apples. In summer, the apples grow bigger and bigger. They get their color from the sun. Some apples are red, some are green, and some are yellow. Farmers pick apples in autumn. They must be careful not to hurt the fruit. After picking, apples are sent to markets and supermarkets. We can eat them fresh, make apple pies, or drink apple juice. Apple trees can live for many years. Some trees in Europe are over 100 years old and still produce apples! Apples are not just delicious, but also good for our health. An apple a day keeps the doctor away! 26. What do bees do for apple trees? A. They eat the leaves. B. They help pollinate the flowers. C. They water the trees. D. They pick the apples. 27. When do farmers pick apples? A. In spring. B. In summer. C. In autumn. D. In winter. 28. What color can apples be according to the passage? A. Only red. B. Only green. C. Only yellow. D. Red, green and yellow. 29. What does the saying “An apple a day keeps the doctor away” mean? A. Apples are expensive. B. Apples are good for our health. C. Doctors like eating apples. D. We should eat apples every meal. 30. Where can you probably read this passage? A. In a storybook. B. In a science magazine. C. In a comic book. D. In a diary. B My name is Tom. I live in the countryside with my grandparents. They have a big vegetable garden. I love helping them in the garden. Every morning, I water the tomato plants. Tomatoes need lots of water and sunshine. They start as tiny seeds. Then they grow into small plants with green leaves. Yellow flowers come out first. After the flowers fall off, small green tomatoes appear. They grow bigger and turn red. It’s exciting to watch them change! We also grow carrots. Carrot seeds are very small. We sprinkle (撒) them on the soil and cover them lightly. Carrots grow under the ground. We can’t see them, but we know they are getting bigger because the green tops above ground grow taller. Grandma says gardening teaches us patience (耐心). We must wait for the plants to grow. It also teaches us to care for living things. When we harvest (收获) the vegetables, we feel very proud. We eat them for dinner. They taste much better than the ones from the supermarket! 31. Where does Tom live? A. In a big city. B. In the countryside. C. In a school. D. In an apartment. 32. What does Tom do every morning in the garden? A. He picks tomatoes. B. He waters the tomato plants. C. He plants carrot seeds. D. He harvests vegetables. 33. What happens after the yellow flowers of the tomato plants fall off? A. Small green tomatoes appear. B. The leaves turn yellow. C. The plant dies. D. Bees come to pollinate. 34. Why does Tom say vegetables from the garden taste better? A. Because they are cheaper. B. Because they are grown by himself. C. Because they are more colorful. D. Because they are sweeter. 35. What does Tom learn from gardening? A. How to cook. B. Patience and caring for living things. C. How to sell vegetables. D. How to use a computer. C Sunflowers are special plants. They are famous for turning their heads to follow the sun. This movement is called heliotropism (向日性). Young sunflowers track the sun from east to west during the day. At night, they turn back to the east to wait for the sunrise. Scientists say this helps them get the most sunlight for photosynthesis. As sunflowers mature , the heavy flower heads stop moving. They usually face east. Facing east helps the flowers get warm quickly in the morning. This attracts more bees for pollination. Sunflowers are very useful. We eat their seeds as snacks. Sunflower oil is healthy for cooking. The stems can even be used to make paper. In many cultures, sunflowers symbolize (象征) happiness and good luck because they look like the bright sun. Planting sunflowers is easy. They need plenty of sunshine and water. With proper care, they will grow tall and strong, bringing beauty and joy to your garden. 36. What is the special characteristic of young sunflowers? A. They close their flowers at night. B. They turn their heads to follow the sun. C. They grow very fast at night. D. They only face north. 37. Why do young sunflowers follow the sun? A. To look for water. B. To get the most sunlight. C. To attract birds. D. To avoid wind. 38.
