Q: Read the following article and select the best answer. Article: There was great excitement on the planet of Venus . Venusian scientists managed to land a satellite on the planet Earth, and it has been sending back signals as well as photographs ever since. The satellite was directed into an area known as Manhattan, named after the great Venusian astronomer Professor. Manhattan, who first discovered it with his telescope 20000 light years ago. Because of excellent weather conditions and extremely strong signals, Venusian scientists were able to get valuable information as to feasibility of a manned flying saucer landing on Earth. A press conference was held at the Venus Institute of Technology. "We have come to the conclusion, based on last week's satellite landing," Prof. Zog said, "that there is no life on Earth." "How do you know this?" the science reporter of the Venus Evening Star asked. "For one thing, Earth's surface in the area of Manhattan is made up of solid concrete and nothing can grow there. For another, the atmosphere is filled with carbon monoxide and other deadly gases and nobody could possibly breathe this air and survive." "What does this mean as far as our flying saucer program is concerned?" "We shall have to take our own oxygen with us, which means a much heavier flying saucer than originally planned." "Are there any other dangers that you discovered in your studies?" "Take a look at this photo. You see this dark black cloud hovering over the surface of Earth? We don't know what it is made of, but it could give us a lot of trouble and we shall have further tests before we send a Venus Being there." "Over here you will notice what seems to be a river, but the satellite findings indicates it is polluted and the water is unfit to drink. This means we shall have to carry our own water, which will add even greater weight to the saucer." "If all you say is true, won't this set back the flying saucer program several years?" "Yes, but we shall continue as soon as the Grubstart gives us the added funds ." Profession. Zog replied. Question: According to the passage, the Venusian scientists succeeded in getting important information about _ . - the feasibility of landing a satellite on Earth - the possibility of making a first-rate flying saucer - the feasibility of sending a Venus Being to Earth - the possibility of directing a flying saucer into Manhattan
A: the feasibility of sending a Venus Being to Earth

Q: Read the following article and select the best answer. Article: "The price of books for our students is just getting higher and higher and,combined with the rising cost of tuition,it's killing these students,"said Peter Jason,a college professor."Remember,students are one of the poorest groups of people in America.Almost half of them have at least one part-time job.In fact,one of my students has three jobs.And she still manages to have high scores and go to school full-time." Textbook prices are traditionally high.Adding to that problem,many college teachers change textbooks year after year;they either upgrade to a new edition or switch to an entirely different textbook.This further hurts students because if an instructor no longer uses a particular textbook,that book has no resale value. Dr.Jason decided to make lire a little easier and a lot cheaper for his students by writing his own book on public speaking."Many books have an increased price because of CD-ROMs,lots of color photographs and pictures.I talked to my students,and many of them,like me,prefer to keep things simple! So,a few years ago,I wrote my own textbook.Compared to most other public speaking books,mine is half the number of pages,and one-third the price.That is,$30 instead of $90.When I wrote a second edition last year,students only had to buy the 35 new pages, For only $7.00,they had almost a new book. Now my loose-leaf textbook enjoys great popularity among the students.Maybe in the future more writers and publishers will try it." Question: What did Dr. Jason say about students at college? - They are short of money. - They need better textbooks - They should do part-time jobs. - They are trying to get high scores.
A: They are short of money.

Q: Read the following article and select the best answer. Article: Imagine this: you get up in the morning and put on a custom printed T-shirt. Then you eat some 3-D printed food and relax on your printed sofa. Perhaps you take a ride in a printed electric car to the hospital to get a printed tooth fitted. Though some of these things may seem impossible, they're closer to reality than you might think. The world of 3-D printing is coming to a store near you soon. The idea of 3-D printing is to produce complicated shapes in a very personalized way. If you want to make a totally new object, you need to make a virtual design in a CAD(computer aided design)file first. Or you can use a 3-D scanner to make a digital copy of an object. Then, based on the design or copy, the 3-D printer makes paper-thin slices out of liquid, plastic, or metal and puts them together to create the object you want. There are many areas in which 3-D printing can change our lives. One such area is health care. Researchers have developed simple 3-D printed organs, which can be used in life-saving operations. A 17-year-old boy in the US has also recently developed a brain-powered, 3-D printed replacement hand. From heart monitors to fake limbs , we can soon be living longer thanks to 3-D printed technology. Another area that 3-D technology looks sure to change is food. Can you imagine being able to print your favorite dishes at home at the touch of a button? Even big companies are behind the trend. Hersheys, one of the largest chocolate makers in the world, recently announced that it would start producing chocolate with the help of 3-D printers. NASA, the US space agency, has reportedly spent $125,000 (767,594 yuan) developing a "3-D pizza printer". It is not yet clear how long it will take until 3-D printers are available to everyone. But one thing is for sure: the possibilities are endless. Question: Compared with traditional manufacturing procedures, 3-D printing _ . - isn't practical in daily life - relies less heavily on the use of 3-D scanners - can produce complicated products in larger sizes or numbers - has an advantage in meeting the personal needs
A: has an advantage in meeting the personal needs
