1 . Instantly, we were busily preparing for the worst. The whole family had experienced such a storm before and everyone remembered the damage it had caused to stock and crops. There was very little we could do about the crops. But we needed to protect the animals in case the river flooded again. My older brother called his sheep-dog and began driving our small flock of sheep to higher ground above river. If the river flooded, they should be safe there.
The underlined word “stock” in the paragraph above refers to _______.| A．money owned by the family | B．goods for sale |
| C．supplies for family use | D．farm animals |
2 . Facebook is an American online social media and social networking service. The Facebook website was launched on February 4, 2004, by Mark Zuckerberg, along with fellow Harvard College students and roommates.
The founders had limited the website’s membership to Harvard students at first; however, later they expanded it to various other universities, and eventually to high school students as well. Since 2006, anyone who claims to be at least 13 years old has been allowed to become a registered（注册了的）user of Facebook, though differences exist in the youngest age requirement, depending on local laws. Facebook has more than 2 billion monthly active users as of June 2017. As of April 2016, Facebook was the most popular social networking site in the world, based on the number of active user accounts.
Facebook may be accessed by a large range of desktops, smartphones over the Internet and mobile networks. After registering to use the site, users can create a user profile showing their names and so on. Users can add other users as “friends”, exchange messages, post photos and so on.
Facebook makes most of its income from advertisements which appear on screen, marketing access for its customers to its users.

3 . When the young donkey Daisy May came to us，she was pregnant. With no donkey experience. I was unprepared for what might come next.
After some difficulty，Daisy’s baby was born. I thought the poor thing was dead. I planned to put the loss behind us and make sure she never got pregnant again. Just then，I heard a little noise. I couldn’t believe that baby was breathing and looking at me!We called him Samson，and of course I became his mother as much as Daisy was.
When Samson was nine months old，I had to separate Daisy and Samson for a few hours a day to wean(使断奶)him，but otherwise he went wherever she did. I think she would be lost without him. His donkey stepdad Bernard taught him to always be ready to have fun. They enjoy playing football together and going for a roll on a hot summer day.
I asked a worker to make a harness(马具)for my three little donkeys. When I brought it home I taught them one by one how to pull a cart. Samson watched and freely followed Daisy. When he was three，I put the harnness on him and he knew exactly what to do.
That was 15 years ago. Now，the most exciting thing about Samson is that he has become a little renowned. People come from all over to see him perform. The neighbors bring their grandchildren，and my sons bring their friends.
Samson shakes hands，unties my shoe，picks up a hat and more. And when I ask him if he has any bad habits，he tries to pick my pocket!He surprisingly learned these tricks himself. I just ask him to do them and he understands.
The relationship I have with my“baby”Samson has been an amazing experience. Every day is a fun day with this superstar donkey.

4 . Far from the land of Antarctica, a huge shelf of ice meets the ocean. At the underside of the shelf there lives a small fish, the Antarctic cod.
For forty years scientists have been curious about that fish. How does it live where most fish would freeze to death? It must have some secret. The Antarctic is not a comfortable place to work and research has been slow. Now it seems we have an answer.
Research was begun by cutting holes in the ice and catching the fish. Scientists studied the fish’s blood and measured its freezing point.
The fish were taken from seawater that had a temperature of -1.88℃ and many tiny pieces of ice floating in it. The blood of the fish did not begin to freeze until its temperature was lowered to -2.05℃. That small difference is enough for the fish to live at the freezing temperature of the ice-salt mixture.
The scientists’ next research job was clear: Find out what in the fish’s blood kept it from freezing. Their search led to some really strange thing made up of a protein never before seen in the blood of a fish. When it was removed, the blood froze at seawater temperature. When it was put back, the blood again had its antifreeze quality and a lowered freezing point.
Study showed that it is an unusual kind of protein. It has many small sugar molecules held in special positions within each big protein molecule. Because of its sugar content, it is called a glycoprotein. So it has come to be called the antifreeze fish glycoprotein. Or AFGP.
