What; big 解析：感叹句，what后面接名词短语a big leaf。 5. doesn’t need 解析：主语The plant是第三人称单数，否定句用doesn’t + 动词原形。 六、阅读理解（每小题2分，共20分） （A） 1. F 解析：短文说“My garden behind my house”，是在房子后面，不是前面。 2. T 解析：短文说“It has many green leaves.”，与句子一致。 3. F 解析：短文说“They are red and yellow.”，不是蓝白相间。 4. T 解析：短文说“I water them every day.”，与句子一致。 5. T 解析：短文说“I can see some small apples on the tree.”，与句子一致。 （B） 1. A 解析：短文第一句说“They need sunlight, water and air to grow.”。 2.
