When scientists set out to explore the roots of human laughter, some apes（类人猿） were just tickled（胳肢）to help. That’s how researchers made a variety of apes and some human babies laugh. After analyzing the sounds, they concluded that people and great apes inherited laughter from a shared ancestor that lived more than 10 million years ago. Experts praised the work, it gives strong evidence that ape laughter and human laughter are related through evolution（进化）.

Scientists have noted that apes make characteristic sounds during play or while being tickled, especially to signal that they’re interested in playing. It’s been suggested before that human laughter grew out of primate（灵长类动物） roots. But ape laughter doesn’t sound like human laughter. It may be slower noisy breathing. So what does that have to do with the human ha-ha? To investigate that, Marina Davila Ross and her colleagues carried out a detailed analysis of the sounds made by tickling three human babies and 21 other primates, apes included.

After measuring 11 features in the sound from each species, they tried to find out how these sounds appeared to be related to each other. The result looked like a family tree. Significantly, that tree matched the way the species themselves are related, the scientists reported online in the journal Current Biology. They also concluded that while human laughter sounds much different from ape laughter, their typical features could have come from the same ancestor.

Panksepp, who studies laughter-like responses in animals but didn’t participate in the new work, called the paper exciting. Panksepp’s own work concludes that even rats produce laughter in response to playing and tickling, with sounds that can hardly be heard by people. Robert Provine, a scientist, who wrote the book, Laughter: A Scientific Investigation, said the new paper showed some important clues, like ape sounds that hadn’t been realized before.

69. Why did the scientists analyze the laughter made by tickling human babies and apes?

A. To try to discover if they can make characteristic sounds.

B. To see if they interested in playing.

C. To find out if the laughter of apes and humans is related.

A. find out ape sounds that hadn’t been realized before

B. find out relations among primates’ laughter

C. see what a family tree from each species looks like

D. make a report online in the journal Current Biology

A. Panksepp spoke highly of the new research.

B. Rat laughter is likely to be related to ape laughter.

 第四部分：任务型阅读（共10小题；每小题1分，满分10分）

请认真阅读下列短文，并根据所读内容在文章后表格中的空格里填入一个最恰当的单词。注意：每个空格只填1个单词。请将答案写在答题卡上相应题号的横线上。

Imagination is the ability to form a mental image of something that is not obtained through the senses. It is the ability of the mind to build mental scenes, objects or events that do not exist, are not present or have not happened in the past.

Everyone possesses some imagination ability. In some it may be highly developed and in others it may be displayed in a weaker form. It is shown in various degrees in various people.

Imagination is not limited only to seeing pictures in the mind. It includes all the five senses and the feelings. One can imagine a sound, taste, smell, a physical sensation or a feeling or emotion. For some people it is easier to see mental pictures, others find it easier to imagine a feeling, and some are more comfortable imagining the sensation of one of the five senses. Training of the imagination gives the ability to combine all the senses.

Imagination makes it possible to experience a whole world inside the mind. It gives you the ability to look at any situation from a different point of view, and enables one to mentally explore the past and the future. In your imagination you can travel anywhere at the speed of light without any problems. It can make you feel free, though temporarily, and only in the mind, from tasks, difficulties and unpleasant circumstances.

 Imagination ha a  great role and value in each one's life. We all use it, whether consciously or unconsciously, in most of our daily affairs. We use our imagination whenever we plan a party, a trip, our work or a meeting. We use it when we describe an event, explain how to arrive to a certain street, write, tell a story or cook a cake.    Imagination is also a creative power that is used extensively in magic, creative visualization and confirmations. It is the creator of circumstances and events. It is necessary for inventing an instrument, designing a dress or a building, painting a picture or writing a book. The creative power of imagination has an important role in the achievement of success in any field.

Imagination can change your whole life. When you know how to work with it, you can make your hearts' desires come true. But if you do not recognize the importance of the power of the imagination, your life may not be as happy and successful as you would have wanted it to be. You may create and attract into your lives events, situations and people that you don't really want. This is actually what most people do, because you don't use the power of imagination correctly.

Lack of understanding of the power of the imagination is responsible for the suffering, incompetence, difficulties, failures and unhappiness people experience, some reason, most people are tending to think in a negative way. They do not expect success. They expect the worst, and when they fail, they believe that fate is against them. This attitude can be changed, and then life will improve accordingly.

Understanding how to use your imagination correctly, and putting this knowledge into practice, for your own and others' benefit, will put you on the golden path to success, satisfaction and happiness.
