【题目】Women are friendly. But men are more competitive. Why? Researchers have found its all down to the hormone oxytocin(荷尔蒙催生素). Although known as the love hormone, it affects the sexes differently.

Women tend to be social in their behavior. They often share with others. But men tend to be competitive. They are trying to improve their social status, said Professor Ryan.

Generally, people believe that the hormone exytocin is let out in our body in various social situations and our body creates a large amount of it during positive social interaction(互动)such as falling in love or giving birth.

But in a previous experiment Professor Ryan found that the hormone is also let out in our body during negative social interactions such as envy.

Further researches showed that in men the hormone oxytocin improves the ability to recognize competitive relationships, but in women it raises the ability to recognize friendship.

Professor Ryans recent experiment used 62 men and women aged 20 to 37.

Half of the participants(参与者)received oxytocin. The other half received placebo(安慰剂).

After a week, the two groups switched with participants. They went through the same procedure with the other material.

Following each treatment, they were shown some video pictures with different social interactions. Then they were asked to analyze the relationships by answering some questions. The questions were about telling friendship from competition. And their answers should be based on gestures, body language and facial expressions.

The results indicated that, after treatment with oxytocin, mens ability to correctly recognize competitive relationships improved, but in women it was the ability to correctly recognize friendship that got better.

Professor Ryan thus concluded:Our experiment proves that the hormone oxytocin can raise peoples abilities to better distinguish different social interactions. And the behavior differences between men and women are caused by biological factor(因素)that are mainly hormonal.”

【题目】 The Brown Bear

My wife Laura and I were on the beach, with three of our children, taking pictures of shore birds near our home in Alaska when we spotted a bear. The bear was thin and small, moving aimlessly.

Just a few minutes later, I heard my daughter shouting, Dad! The bear is right behind us! An aggressive bear will usually rush forward to frighten away its enemy but would suddenly stop at the last minute. This one was silent and its ears pinned back--the sign(迹象) of an animal that is going in for the kill. And it was a cold April day. The bear behaved abnormally, probably because of hunger.

I held my camera tripod(三脚架) in both hands to form a barrier as the bear rushed into me. Its huge head was level with my chest and shoulders, and the tripod stuck across its mouth. It bit down and I found myself supporting its weight. I knew I would not be able to hold it for long.

Even so, this was a fight I had to win: I was all that stood between the bear and my family, who would stand little chance of running faster than a brown bear.

The bear hit at the camera, cutting it off the tripod. I raised my left arm to protect my face; the beast held tightly on the tripod and pressed it into my side. My arm could not move, and I sensed that my bones were going to break.

Drawing back my free hand, I struck the bear as hard as I could for five or six times. The bear opened its mouth and I grasped its fur, trying to push it away. I was actually wrestling(扭打) with the bear at this point. Then, as suddenly as it had begun, the fight ended. The bear moved back towards the forest, before returning for another attack--the first time I felt panic.

Apparently satisfied that we caused no further threat, the bear moved off, destroying a fence as it went. My arm was injured, but the outcome for us could hardly have been better. I'm proud that my family remained clear-headed when panic could have led to a very different outcome.

D. set up a barrier for itself

A. felt safe

B. got injured

C. found some food

D. took away the camera
