Bill Gates and the president of General Motors have met for lunch, and Bill is going on and on about computer technology. “If automotive technology had kept pace with computer technology over the past few decades, you would now be driving a V-32 instead of a V-8, and it would have a top speed of 10，000 miles per hour，” says Gates. “Or, you could have an economy car that weighs 30 pounds and gets a thousand miles to a gallon of gas. In either case, the sticker price of a new car would be less than $50. Why haven't you guys kept up？”
The president of GM smiles and says, “Because the federal government won't let us build cars that crash four times a day.”
Why is that funny (or not funny, as the case may be) Human beings love to laugh, and the average adult laughs 17 times a day. Humans love to laugh so much that there are actually industries built around laughter. Jokes, sitcoms and comedians are all designed to get us laughing, because laughing feels good. For us it seems so natural, but the funny thing is that humans are one of the only species that laughs. Laughter is actually a complex response that involves many of the same skills used in solving problems.
Laughter is a great thing—that's why we've all heard the saying, “Laughter is the best medicine.” There is strong evidence that laughter can actually improve health and help fight disease. In this article, we'll look at laughter—what it is, what happens in our brains when we laugh, what makes us laugh and how it can make us healthier and happier. You'll also learn that there's a tremendous amount that no one understands yet.

C．The president of GM thinks it is impossible to build cars worth less than 50 dollars.
D．If cars were less than 50 dollars, a large number of accidents would happen per day.

In addition to their daily tasks, the brave Mars pioneers will also have to be ready to deal with all kinds of medical mon colds and headaches may be easy to deal with medication. To help them with more serious issues, like severe skin burns or bone fractures, scientists from the Dresden University of Technology (TUD) have developed a 3D bio-printer capable of producing human tissue in space.
3D bio-printers are similar to traditional 3D printers with one key difference. Instead of creating objects from materials like plastic, they deposit layers of biomaterial, made largely from living cells, to build complex human tissue. Since the raw material is not readily available, researchers begin by taking a few cells from the required organ, such as lung or skin, and cultivating (培养) them in the laboratory. Once enough cells have been generated, they are used to create “bio-ink，” which is loaded into the printer.
This, as you can imagine, is no easy task, and despite trying for many years, scientists have still not been able to regenerate human organs for widespread use. Bio-printing in space has even more challenges. The biggest is finding cells to cultivate and create the required bio-ink.
The TUD scientists believe the difficulty can be overcome by using cells from the injured astronaut. “Using biomaterial from the astronauts themselves also eliminates the risk of transplant rejection，” says Nieves Cubo Mateo, a bio-printing specialist at TUD.
The TUD researchers, who revealed the first bio-printed bone and skin samples, believe that once developed, the technology could help astronauts treat acute injuries. Tommaso Ghidini, head of ESA's Structures, Mechanisms and Materials Division says, “Carrying enough medical supplies for all possibilities would be impossible in the limited space and mass of a spacecraft. Instead, a 3D bio-printing capability will let them respond to medical emergencies as they arise.”
5．What makes 3D bio-printers different from traditional 3D printers？(　　)
A．The efficiency of work.
B．The principle of operation.
C．The progress to make objects.
D．The material used to make objects.
6．What is the biggest obstacle of using bio-printing in space？(　　)
A．How to get raw material.
B．How to reduce the risk of rejection.
C．How to deal with more serious issues.
D．How to take cells from the injured astronaut.
7．Which can replace the underlined word “eliminates” in paragraph 4？(　　)
A．Increases. B．Removes.
C．Takes. D．Assesses.
8．What's Tommaso Ghidini's attitude to 3D bio-printer？(　　)
A．Doubtful. B．Supportive.
C．Objective. D．Indifferent.
