语法填空

What will cars be like in the future? Maybe we can sit in a car that can drive all by 【小题1】（it） in a few years’ time. In fact, with the rapid development of modern science and technology, the self-driving car is becoming a 【小题2】（real） on busy streets.

According to a report by Google, the world-famous search engine, its self-driving cars 【小题3】（travel） more than 700,000 miles on roads in California so far. The first self-driving car 【小题4】（make） by Google came out in 2009. There are cameras on the top of the car, 【小题5】 allow the computer in the car to draw a 3-D map of the surroundings. In addition, Google says that its self-driving cars can discover hundreds of separate 【小题6】（object）at the same time, which might be an improvement on the human driver experience. As 【小题7】 result, there will be far 【小题8】（few） traffic accidents caused by careless driving.

However, self-driving cars are much too 【小题9】（expense） right now. Scientists across the world are doing their best to bring down the costs, 【小题10】 hundreds of thousands of dollars to the cost that most people can afford.

   Government intelligence agencies have a plan to build computers that store information inside DNA and other organic molecules（分子）.

Intelligence Advanced Research Projects Activity（IARPA）announced plans to develop tabletop-sized machines that can store and retrieve（取回）data from large batches of polymers — a term that refers to a wide variety of long，string-like molecules. Polymers can store data in individual atoms or groups of atoms.

The project is an attempt to solve a basic problem of the modern era:the vast and growing costs of data storage. Datacenters around the world sucked up 416. 2 terawatt hours of electricity in 2016. That's about 3 percent of the global supply，and it accounts for 2 percent of global greenhouse gas emissions.

A 2016 paper found that DNA，in particular，could store computer information more densely，require less energy，and survive higher and lower temperatures than conventional hard drives. The authors of that paper reported on the successes of prototype（雏形）DNA computers that used the genetic molecules for both long-term storage and random access memory（RAM）.

But no one has yet figured out how to handle DNA data storage on large scales.

IARPA officials said the new effort, called Molecular Information Storage, will be broken up into three periods:a two-year program to figure out how to store data in DNA or other molecules at high speed,a two-year program to figure out how to retrieve that data at high speed, and a two-year effort to develop an operating system that can run on that DNA.

Many of the technologies IARPA wants to develop are untested at these scales, so it's unclear how far away that proposed tabletop device really is.

A．Produce and save less energy.

B．Store more information faster.

C．Be better for the environment.

D．Control temperatures more easily.

【小题4】Where can you find the course of the test about Molecular Information Storage？

A．In Paragraph 3.	B．In Paragraph 4.
C．In Paragraph6.	D．In Paragraph 7.
