An Intelligent CarDriving needs sharp eyes, keen ears, quick brain, and coordination(协调) between hands and the brain. Many human drivers have all (51) and can control a fast-moving ear. But how does an intelligent car control itself?There is a virtual(虚拟) driver in the smart car. This virtual driver has "eyes", "brains", "hands" and "feet" too. The minicameras (52) each side of the ear are his "eyes" which (53) the road conditions ahead of it. They watch the (54) to the car’s left and right. There is also a highly automatic driving (55) in the car. It is the built-in computer, which is the virtual driver’s "brain". His "brain" (56) the speeds of other moving cars near it and analyzes their positions. Basing on this information, it chooses the (57) path for the intelligent ear, and gives instructions to the "hands" and "feet" to act accordingly. In this way, the virtual driver (58) his car.What is the virtual driver’s best advantage He reacts (59) . The minicameras are bringing (60) continuously to the "brain". It completes the processing of the images with-in 100 milliseconds. (61) , the world’s best driver needs at least one second to react. Besides, when he takes (62) , he needs one more second.The virtual driver is really wonderful. He can reduce the accident (63) considerably on expressways(高速公路). In this (64) , can we let him have the wheel at any time and in any place Experts (65) that we cannot do that just yet. His ability to recognize things is still limited. He can now only drive an intelligent car on expressways. 51()

A. these
B. them
C. this
D. that

Unlocking the Human Genome (基因组)1 A project to unlock secrets--what scientist could resist that challenge This is what many scientists are doing as they work on the Human Genome Project. The aim of the project is to decode (破译) all of the some 100,000 genes in the human body. Scientists are using DNA fingerprinting techniques to do the decoding.2 DNA is the substance found in the chromosomes(染色体)of a cell. A chromosome is a chain of genes. Each gene carries a piece of genetic information. At any one moment in a cell, thousands of genes are turned on and off to produce proteins (蛋白质). The challenge for scientists is to find out what role each gene plays in protein production. At some point this decoding will be complete. Then scientists will have a map of an ideal genome, or a picture of the total genetic nature of a human being. The ideal genome is called a consensus(交感)genome. Everything works well in a consensus genome.3 But no one in the world has a consensus genome. Everyone’s genome is different from the ideal. These differences are referred to as genetic mutations(突变). Genetic mutations in a person’s genome mean that the person has a greater than average chance of suffering from health problems. Some problems are not life-threatening. These would include things like colorblindness, or mild headaches. Other problems are serious, such as heart disease or cancer.4 It will take years to identify the role of each of the 100,000 genes. The short-term goal of the project is to find the physical and mental health problems a person is likely to encounter during his or her lifetime. The long-term goal is to have each person live a longer, healthier life.A. How does DNA workB. What is the Human Genome Project aboutC. How are the DNA samples collectedD. What are the goals of the Human Genome ProjectE. What is the role of each geneF. What are the consequences of genetic mutations Paragraph 3()
