"If you come by right now,"the receptionist said,"the dentist will fit you in ." I look my purse and keys and rushed to my car. But suddenly I began to doubt about the dentist.What kind of dentist would be so eager to treat someone at such short notice?Why wasn't he as busy as the others?

The chair went back,suddenly I smiled.There was a beautiful picture, right where I could enjoy it: on the ceiling .How considerate the dentist was !

Read the following article and select the best answer. Article: I always avoid going on field investigations with the toxics team, unless it's ly necessary. It's not that I mind the hard work, or am afraid of coming into contact with toxic substances. What I fear is quickly losing hope about the work I do. However, doing field research with the toxic team, all I see and feel is filth---nothing else. Even if I close my eyes, I can smell the smell of food processing, rotting organic waste from paper mills and chemicals from clothing manufacturers. One morning, I went to investigate a discharged pipe to document and collect samples of pollutants secretly being emitted by a textile mill. I had to work with the utmost secrecy in order to avoid being discovered by the textile mill. I dipped a long measuring pole into the large polluting pipe to measure the volume of polluted water being emitted. But the surface of the water, covered in oil and filth, made me feel as if to vomit . All of a sudden, I felt someone hit me on my back, it frightened me so much that I almost fell into the water. I grasped the pole and looked behind me to see an old man standing there. He asked: "Can you catch fish here?" I realized that he thought I was holding a fish pole, so I kept calm and said: "Yes, I heard that there's a kind of small fish living in this water, and it has medicinal benefits." The old man grew quite curious and replied: "That may be. If a fish can survive in water as dirty as this, it must have a lot of resistance. So it wouldn't be too strange if such fish had medicinal benefits." It was clear he was just passing by, so I answered: "Yeah, survival of the fittest. Fish that adapt can survive, just like us humans." He kept talking to me and didn't want to leave. He wanted to see whether or not I would catch the small fish with medicinal benefits. Question: The text is mainly about _ . - a research report about pollution. - an exciting experience of fishing. - an experience of doing research on pollution - an unforgettable talk with an old man.
**Answer**
an experience of doing research on pollution

Read the following article and select the best answer. Article: Ever get that feeling you're being watched? Well, if you're a dog-owner, you may have a point. Dogs are able to watch people's interactions with one another to determine who holds yummier treats, according to a new study. This study joins others that show dogs are good observers of human behaviors and feelings. It offers evidence that dogs use information not only from people's direct interactions with them, but also their interactions with one another. In the study, dogs watched a man ask two women for some of their corns. Both women gave the man corns when he asked, but in response to one woman, the man showed his enthusiasm and said the corns were so delicious. In response to the other woman, he gave the corns back and called them _ (in Spanish;the study was conducted in Argentina). After these interactions, the man left and an assistant holding the dog let the dog go. While many dogs didn't approach either woman, the dogs that did have a preference tended to prefer the woman with the yummier food. Other studies of dogs' people-watching ability have found dogs are able to tell the difference between happy and sad faces in their owners. They prefer people who give others food when asked over people who don't give others food. And in one study, dogs turned toward crying people more often than toward talking people. So how much do dogs really understand about the humans around them? That's not totally settled yet. In a strange twist to the Argentine study above, when the researchers tried an experiment in which they put two plates of corns on a table and had a man react to each plate, dogs didn't preferentially approach the tastier plate afterward. You could say dogs watch for the interaction between two persons, not just how a person reacts. Yet a previous study found dogs will choose boxes that people reacted to happily, but not boxes people reacted to with a disgusted face. Well, either way, you can be sure Fluffs is keeping an eye on you, to the best of her ability. The study was published in the journal... Question: Which is one of the procedures of the Argentine study? - The man had different reactions to the food received. - One of the women didn't give the food to the man. - The assistant accompanied the dogs to get the food. - Many dogs went to one of the women.
**Answer**
The man had different reactions to the food received.
