One warm day when I was walking in my backyard, I saw a pinecone(松球) on the ground. I picked it up, and some seeds fell out of it. Those seeds would be a tasty treat for a squirrel (松鼠).
I realized that pinecones were not always open like this one. Sometimes cones were tightly closed. I decided to find out why.
I gathered pinecones from my backyard. I watched them for over a year. Here’s what I learned.
Pinecones open and close slowly as the weather changes. When it’s cold or wet, cones are tightly closed. This protects the seeds inside from rain and snow.
When the weather becomes warm and dry, pinecones open. On a hot day, you might even hear the sound of cones popping open. The seeds inside may then fall to the ground. The wind may blow the seeds to places where they can grow into new pine trees. A seed has a better chance of taking root and growing when the weather is warm.
“Pine seeds are an important source of food for many animals,” says Monty Maldonado. He is a pinecone expert with the United States Forest Service. He says squirrels depend on pinecone seeds for most of their meals. They spend lots of time gathering and storing the cones. Maldonado says some animals eat only the seeds from a pinecone. But red squirrels and gray squirrels will eat the whole thing.
Small animals aren’t the only creatures that eat pine seeds. Maldonado says big grizzly bears (灰熊) and people eat them, too.
Seeds inside a pinecone are important for the growth of new trees and as food for animals. It is the pinecone’s job to protect them. So take note of the pinecones you see on the ground. They hold treasures inside.

A．are open   B．are usually shut       C．grow quickly    D．stop growing
46．According to Monty Maldonado,        .
A．not all squirrels eat the whole pinecone

Growing trees in the concrete jungle of Los Angels brings neighbors benefits beyond beauty.
