Zero gravity looks cool. But what about the thing no one likes to talk about? Yes, that is right: going to bathroom. Zero gravity makes this everyday task quite a challenge. Astronauts have to be toilet-trained all over again.
The Apollo astronauts raised themselves off the seat of their chairs and stuck a clear plastic bag to their back sides with sticky strips. A second astronaut watched closely to be sure no waste matter escaped the seal. (You would not want that stuff floating around the cabin!) When the deed was done, the astronaut cleaned up with a piece of plastic attached to the inside of the bag, removed the bag, dropped a disinfectant pill in with the waste matter, and put the whole thing, sealed, into a special container.
Donald W. Rethke, an engineer for Hamilton Standard Space Systems, developed a more private way to answer nature’s call: the space toilet. It is somewhat like the kind of toilet one would find on commercial airplanes --- with unique adaptations for zero gravity, of course. For instance, it has thigh bars that keep the astronaut from floating off the seat.
The astronaut (male or female) defecates (排便) in a bag and urinates (排尿) in a hose. Solid and liquid wastes are kept separated because at least 85% of the urine is recycled and, yes, after careful filtration, used for drinking and other purposes. (Water is always in demand in space.) A vacuum sucks the waste materials into the toilet, where the waste is compacted into hamburger-like patties for easy storage. Although not exactly like an earthbound visit to the toilet, it is at the very least much more private than in the early days of space travel.
1.According to the first paragraph, the lack of the gravity can turn something as simple as _______ into a major challenge.
A. eating B. taking baths
C. sleeping D. answering nature’s call
2.How did astronauts use toilet systems in the Apollo days?
A. None of the waste was separated as it is now.
B. Solid waste was compressed and stored on board.
C. The toilet units used water to remove the waste through the system.
D. The astronauts each used their own private restroom.
3.To ensure the user remains seated, the toilet comes equipped with _______
A. a plastic bag B. a sticky strip
C. a wide hose D. a thigh bar
4.What can be inferred from the fact that most of the astronauts’ urine is recycled?
A. The recycled water tastes better.
B. Water is limited on the space shuttle.
C. It is very convenient to get their urine recycled.
D. Space science includes recycling urine.

We know the famous ones — the Thomas Edisons and the Alexander Graham Bells — but what about the less famous inventors? What about the people who invented the traffic light and the windshield wiper(雨刮器)? Shouldn’t we know who they are?
Joan Mclean think so. In fact, Mclean, a professor of physics at Mountain University in Range, feels so strongly about this matter that she’s developed a course on the topic. In addition to learning “who” invented “what”, however, Mclean also likes her students to learn the answers to the “why” and “how” questions. According to Mclean, “When students learn the answers to these questions, they are better prepared to recognize opportunities for inventing and more motivated to give inventing a try.”
Her students agree. One young man with a patent for an unbreakable umbrella is walking proof of Mclean’ statement. “If I had not heard the story of the windshield wiper’s invention,” said Tommy Lee, a senior physics major, “I never would have dreamed of turning my bad experience during a rainstorm into something so constructive.” Lee is currently negociating to sell his patent to an umbrella producer.
So, just what is the story behind the windshield wiper? Well, Mary Anderson came up with the idea in 1902 after a visit to New York City. The day was cold and stormy, but Anderson still wanted to see the sights, so she jumped aboard a streetcar. Noticing that the driver was struggling to see through the snow covering the windshield, she found herself wondering why there couldn’t be a built-in device for cleaning the window. Still wondering about this when she returned home to Birmingham, Alabama, Anderson started drafting out solutions. One of her ideas, a lever(操作杆) on the inside of a vehicle that would control an arm on the outside, became the first windshield wiper.
Today we benefit from countless inventions and innovations. It’s hard to imagine driving without Garrett A. Morgan’s traffic light. It’s equally impossible to picture a world without Katherine J. Blodgett’s innovation that makes glass invisible. Can you picture life without clear windows and eyeglasses?
1.By mentioning “traffic light” and “windshield wiper”, the author indicates that countless inventions are ________.
A. beneficial, because their inventors are famous
B. beneficial, though their inventors are less famous
C. not useful, because their inventors are less famous
D. not useful, though their inventors are famous
2.Professor Joan Mclean’s course aims to ________.
A. add colour and variety to students’ campus life
B. inform students of the windshield wiper’s invention
C. carry out the requirements by Mountain University
D. prepare students to try their own invention
3.Tommy Lee’s invention of the unbreakable umbrella was ________.
A. not eventually accepted by the umbrella producer
B. inspired by the story behind the windshield wiper
C. due to his dream of being caught in a rainstorm
D. not related to Professor Joan McLean’s lectures
4.Which of the following can best serve as the title of this passage?
A. How to Help Students to Sell Their Inventions to Producers?
B. How to Design a Built-in Device for Cleaning the Window?
C. Shouldn’t We Know Who Invented the Windshield Wiper?
