At a laboratory in Germany ,volunteers slide into a machine and perform simple tasks, such as deciding whether to add or subtract two numbers , or choosing which of two buttons to press.

They have no idea that scientists in the next room are trying to read their minds-using a brain scan to figure out their intention before it is turned into action.

In the past ,scientists had been able to detect decisions about making physical movements before those movements appeared .But researchers at Berlin's Bernstein Center for Computational Neuroscience claim they have now , for the first time ,identified people's decisions about how they would later do a high-level mental activity-in this case ,adding versus subtracting.

While still in its initial stages ,the techniques may eventually have wide-ranging implications for everything from criminal questioning to airline security checks.

The research,which began in July 2005,has been of limited scope:only 21 people have been tested so far.And the 71 percent accuracy rate is only about 20 percent more successful than random selection.

Still ,the research conducted at the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig ,about 150 kilometers southwest of Berlin ,has been generating strong interest in the scientific community.

In one study ,participants were told to decide whether to add or subtract two numbers a few seconds before the numbers were flashed on a screen . Meanwhile ,a computer captured images of their brain waves to predict the subject's decision-with one pattern suggesting addition, and another subtraction.

The team ,headed by Haynes ,began its research by trying to identify which part of the mind was storing intentions. They discovered it was found in the prefrontal cortex region by scanning the brain to look for bursts of activity when subjects were given choices.

Then they went about studying which type of patterns were associated with different intentions.

"If you knew which thought signatures to look for ,you could theoretically predict in more detail what people were going to do in the future," said Haynes.

75.Which of the following is true about the experiment at the laboratory?

A.The volunteers are asked to perform very complicated tasks.

B.Everything was explained to the volunteers before the experiment.

C.The volunteers cannot see the scientists while performing the tasks.

76.Which of the following demonstrates the major breakthrough made by the German scientists?

A.By studying the subjects' brain waves , they know what physical movements they'll make.

B.By studying the subjects' brain waves, they know what mental task they'll perform.

C.By studying criminals' brain waves ,they can help find out whether they are lying or not.

D.By studying passengers' brain waves ,they can help find out who intends to make trouble.

张某在一风景区旅游，爬到山顶后，见一女子孤身站在山顶悬崖边上，目光异样，即心生疑惑。该女子见有人来，便向悬崖下跳去，张某情急之下拉住女子衣服，将女子救上来。在救人过程中，张某随身携带的价值2000元的照相机被碰坏，手臂被擦伤；女子的头部也被碰伤，衣服被撕破。张某将女子送到山下医院，为其支付各种费用500元，并为包扎自己伤口用去20元。当晚，张某住在医院招待所．但已身无分文，只好向服务员借了100元，用以支付食宿费。次日，轻生女子家人赶到医院，向张某表示了感谢。根据上述情况，请回答下列问题。

张某能否请求该女子给付一定的报酬( )

A．不能，因为是做好事不求报酬

B．能，因为张某挽救了轻生女子的生命

C．不能，因为无因管理是无偿的

D．能，因为有法律依据
