1 . If you ever get the impression that your dog can "tell" whether you look content or annoyed, you may be onto something. Dogs may indeed be able to distinguish between happy and angry human faces, according to a new study
Researchers trained a group of 11 dogs to distinguish between images（图像）of the same person making either a happy or an angry face. During the training stage, each dog was shown only the upper half or the lower half of the person's face. The researchers then tested the dogs' ability to distinguish between human facial expressions by showing them the other half of the person's face on images totally different from the ones used in training. The researchers found that the dogs were able to pick the angry or happy face by touching a picture of it with their noses more often than one would expect by random chance.
The new study focused on whether dogs can_________.
| A．distinguish shapes | B．make sense of human faces |
| C．feel happy or angry | D．communicate with each other |
A. Putting aside employment prospects(就业前景)and the expectations of my parents, the major I’d most like to study is computer science.

3 . Companies which sell liquids like drinks or shampoo rely on bottles for their packaging. Usually these bottles are made of plastic or glass. But as customers have become more concerned about the environment, many companies have begun working to develop paper bottles.
Paper bottles are easy to recycle. They also weigh less than glass or plastic, meaning they’ll require less energy to produce and to move around. They’re usually made from wood pulp (纸浆), which is pressed into a mold (模具) to create the bottle shape. Since paper is soft and easy to mold, companies can design their bottles to take almost any shape they choose.
What’s the main purpose of developing paper bottles?
| A．To make packaging less heavy. |
| B．To reduce the use of raw materials. |
| C．To be more environmentally friendly. |
| D．To cut down on the costs of packaging. |

6 . Vincent van Gogh (1853-1890), perhaps the most famous artist in the world, is perceived by many as the “mad” artist. His artistic genius is often overshadowed by those who see his paintings as only visual expressions of his troubled mind. While in part this may be true, in reality his innovative and unique artistic style was of enormous importance to a host of artists who followed in his wake. Even when openly influenced by his predecessors or contemporaries (前辈或同辈), his art remained identifiably his own, developing a distinctive style that failed to be accepted by the art-buying public in his own time. The career of Vincent van Gogh as a painter was short, but his extraordinary boldness of his technique created masterpieces that exercise a profound influence on the art of the twentieth century.
What is probably the author’s attitude towards Vincent van Gogh?
| A．Appreciative. | B．Suspicious. |
| C．Objective. | D．Confused. |
“Every cloud has a silver lining.” It drives me crazy when Mom says nonsense (废话) like that.
I’d barely had time to arrange myself in the passenger seat, my foot already blown up like a balloon when she came out with it, exactly like I knew she would. First, she patted my leg. Then she just couldn’t help herself, “Every cloud has a silver lining, you know, sweetheart.” “Mom, I appreciate the thought, but I’m not ready to look on the bright side of this.” We hadn’t even left the school parking lot yet.
On the farthest side of the field, I could see my teammates doing sprint training, Coach Zito striding back toward them. He’d mercifully helped me to the car in silence. Unlike Mom, he knew when it was best to say nothing.
As Mom started the engine, I imagined my teammates cooling down without me while they listened to Coach Zito’s pep talk. And next Thursday, they would go to practice without me, and the Thursday after that. When I had fallen and twisted my ankle, I’d cried from the pain, but I was crying out of self-pity in the car. Hours and hours of training， and then this. I told myself there was a glimmer (微光) of hope that everything would turn out okay, and that I’d make it to the track meet next month, but I knew it was just that: a glimmer. The tears fell hot and fast. Mom gave me a weak smile. “It’ll be okay, Casey.“ I suspected this was another version of the silver lining thing, but I felt so miserable that I let it pass.
We finally arrived at the hospital. Doctor Van gently moved my ankle around a bit before carefully lowering it. I nervously asked how long it would be before I could run. “Four weeks maybe, possibly five, “he replied. “And even then, you’ll need to take it easy for a while. Is that possible?” he asked with a smile.
I couldn’t answer.
One month later, I made my appearance on the field.
| A．Five weeks meant little chance for me to the track meet. Looking down at my swollen foot, I wept bitter tears, knowing my last glimmer of hope was fading. As usual, Mom patted me on the shoulder and said with a smile, “sweetheart, every cloud...”“No...”I interrupted her impatiently. Life seemed dull and meaningless, but touched by Mom’s great help, I regained my confidence and was back on my feet. Amazingly, I began to practice running soon. |
| B．I was lying calmly on the bed. Seeing my mother come into the ward (病房)，I greeted her with a smile. When she asked what happened, I told her I was not going to play sports anymore. After hearing my words about the accident, she was quite surprised how I could still remain so optimistic. I patted my mom on the shoulder and comfort her. In my view, it is a great opportunity to have a good rest and rethink about my future life. |
| C．I saw my doctor carrying the medical bag and waiting for me. He explained, “I came here to see my patient. “The delighted man warmly welcomed me, asking me whether I conducted a thorough examination and suggested appropriate following-up care. I thanked him with gratitude. Before he left, my mother came, asking,” How did you know to come to see my son? I didn’t call!” |
| D．All my teammates were absolutely astonished at my quick recovery, not believing their eyes. “OH, boy! What a miracle!” My coach Zito looked at me in disbelief. To tell them everything was okay, I kicked, jumped and ran in front of them. Seeing this, they all burst out laughing. Later, I went to practice with them and participated in the track meet. From then on, whenever I encountered difficulties, Mom’s encouraging words “Every cloud has a silver lining” always rang in my ears. |
8 . But actually, hacking is just an activity. What separates any activity from a crime is, very often. permission. People are free to drive, but they do not have permission to drive 150 miles per hour, which is a criminal offense. Since a driver is just a driver. why must a hacker be a criminal? Someone who engages in the illegal use of hacking should not be called a ‘bad hacker’ but a ‘cybercriminal’. Contrary to popular belief, most hackers like Mike’s father undoubtedly play an important role in keeping companies and people safe.

10 . We’ve all been there: in a lift, in line at the bank or on an airplane surrounded by people who like us, deeply focused on their smartphones or, worse, struggling with the uncomfortable silence.
