It is easy to lose patience with science today． The questions are pressing: How dangerous is air pollution? What about low-level radiation? When will that horrible earthquake strike California? And why can't we predict weather better? But the evidence is often described as "uncertain", forcing scientists to base their points of view almost as much on intuition（直觉）as on science．
When historians and philosophers of science listen to these questions, some conclude that science may not be able to solve all these problems any time soon． The unknowns can grow into riddles that are impossible to solve． Because of the unstable and changing state of the earth's atmosphere, for example, scientists have struggled for centuries to predict the weather with precision（精确） but failed．
The case is different for scientists of astronomy． For example, they think that the gravitational force of a nearby space vehicle, though tiny, is able to change the path of a much larger planet if the vehicle spends enough time close to it． With the aid of Newton's laws of gravitational attraction, ground controllers can predict the path of a planetary probe （探测仪）-or satellite-with incredible accuracy． They do this by calculating the gravitational force from each of the passing planets until the probe speeds beyond the edge of the solar system．A much more difficult task is to calculate what happens when two or three times of such force pull on the probe at the same time． Such procedures can, of course, be very difficult, but for experiments, they are effective．
This range of questions-from simple problems to those impossibly complex-has resulted in nicknames for various fields of study: "soft" sciences and " hard " sciences．“Soft” sciences admit a great degree of uncertainty． Academicians tend to judge fields such as sociology, psychology, and political science as “soft” because they are assumed to be understandable, of unnecessary mathematical accuracy, and concerned with everyday affairs such as interpersonal relationships． However, "hard" sciences, such as astronomy and chemistry, are said to offer precise answers． Precise definitions for "hard" sciences vary, but the characteristics of "hard" sciences include: producing testable predictions; performing controlled experiments; relying on quantifiable data and mathematical models; a high degree of accuracy and objectivity; and generally applying a pure form of the scientific method

Today just as technology changed the face of industry, farmers have undergone an "agricultural revolution". On the farm of today, machines provide all the power.
One of the most important benefits will be the farm computer. A few forward-looking farmers are already using computers to help them run their farms more efficiently. The computers help them keep more accurate records so they can make better decisions on what crops to plant, how much livestock to buy, when to sell their products, and how much profit they can expect. Many computer companies have been developing special computer programs just for farmers. Programs are being written for hog(猪) producers, grain farmers, potato farmers, and dairy farmers. In the future, farmers will be able to purchase computer programs made to their needs. Because of the growing importance of computers on the farm, students at agricultural colleges are required to take computer classes in addition to their normal agricultural courses. There can be no doubt that farmers will rely on computers even more in the future. While the old-time farm depended on horse power, and modern farms depend on machine power, farms of the future will depend on computer power.
Another technological advance which is still in the experimental stage is the robot, a real "mechanized hired hand" that will be able to move and, in some ways, think like a human being. Unlike farmers of the present, farmers of the future will find that many day-to-day tasks will be done for them. Scientists are now developing robots that will be able to shear(修剪) sheep, drive tractors, and harvest fruit. Even complex jobs will be done by robots. For example, in order to milk their cows, farmers must first drive them into the special barn(畜棚), then connect them to the milking machines, watch the machines, and disconnect them when they are finished. In the future, this will all be done by robots. In addition, when the milking is completed, the robots will automatically check to make sure that the milk is pure. The complete mobilization of the farm is far in the future, but engineers expect that some robots will be used before long.Which sentence carries the main idea of the whole passage?

Do you know soon eleven biggest food and drink companies of the nations will adopt new rules to limit advertising to children under the age of 12, a move that restricts ads for products such as McDonald’s Happy Meals and the use of popular cartoon characters.
The companies announced their new rules ahead of a Federal Trade Commission hearing on Wednesday that steps up pressure on the companies to help solve the growing child obesity problem through more responsible marketing. The self-given rules include promises by seven companies who will no longer use licensed characters, such as those made popular through movies or TV shows, to advertise online or in print media unless they’re promoting their healthier products. Four other companies said they do not advertise at all to children under 12.
“I think this is a very good step forward. It’s not the end of the journey but it’s a good way down the road,” said Margo Wootan, Nutrition Policy Director at the nonprofit Center for Science in the Public Interest.
Since the FTC first publicly raised the issue in 2005, many of the companies have started selling products with better nutrition in mind. The companies hope their self-regulation efforts — organized through the Council of Better Business Bureaus — will fend off any new and more strict federal regulation.
Parents are happy to see new rules that restrict the use of cartoon characters such as Shrek, Dora the Explorer and SpongeBob SquarePants. “It catches their eyes when you’re shopping,” said Josephine Thomas, a mother of three boys who lives in Manhattan. “As soon as they see a Shrek or Mickey Mouse, they automatically look at that and they don’t see what they really need. That’s one of the biggest problems when you go shopping.” That’s one reason the food companies have said they will now only use licensed characters to advertise their “better for you” products. The reason why the food and drink companies will take action is that they want to___________
| A．promote sales across the country |
| B．limit advertising to children under the age of 12 |
| C．meet increasing demands from kids |
| D．adapt to the new federal regulations |
What can we learn from the text that the seven companies ____.
| A．may still use cartoon characters in advertising |
| B．are going to stop advertising to children under 12 |
| C．Would like to continue the cooperation with entertainment media |
| D．will make food and drink specially for fat kids |
What of the following can best describe the underlined words “fend off”?
| A．prevent ... from happening | B．draw up or work out |
| C．pay attention to | D．give a warm welcome to |
What does Josephine Thomas advise in the last paragraph?
| A．kids spend too much on unhealthy food |
| B．parents are strict about their kids’ food choice |
| C．“better for you” products are popular with kids |
| D．ads with cartoon characters mislead kids |

Every day we go to school and listen to the teacher, and the teacher will ask us some questions. Sometimes, the classmates will ask for your opinions of the work of the class. When you are telling others in the class what you have found out about these topics, remember that they must be able to hear what you are saying. You are not taking part in a family conversation or having a chat with friends—you are in a slightly unnatural situation where a large group of people will remain silent, waiting to hear what you have to say. You must speak so that they can hear you—loudly enough and clearly enough but without trying to shout or appearing to force yourself.
Remember, too, that it is the same if you are called to an interview whether it is with a professor of your school or a government official who might meet you. The person you are seeing will try to put you at your ease (not worried) but the situation is somewhat different from that of an ordinary conversation. You must take special care that you can be heard. When you speak to the class, you should speak ________.
| A．as slowly as possible | B．in a low voice |
| C．loudly | D．forcefully |
The situation in the class is _________that in your house.
| A．not very different from | B．sometimes the same as |

Superman, Spider-Man, Batman and Iron Man ... .There is no shortage of superheroes. You find them in comic books, on the TV and the big screen.
In a survey of fans by the sci-fi and fantasy website, SFX.co.uk, Batman, 70 years old this year, was voted Britain's favorite superhero.
Unlike many crime-fighting superheroes Batman has no special powers. He can't fly like Superman or shoot a sticky web like Spider-Man.
Bruce Wayne is born to a wealthy Gotham City business family. However, when his parents are murdered his life changes completely.
Wayne feels anger at their deaths and guilty that he did not prevent them. He travels around the world learning how to fight. Upon returning to Gotham, he creates a disguise (伪装) to enable him to fight crime without being recognized.
A childhood fear of bats leads him to choose to dress as one. His idea is that through the bat person he can prove to himself that he has overcome his childhood fears.
Wayne is the CEO of the company he inherits (继承) from his father. He seems to live the lifestyle of a millionaire playboy. But this is a ruse (计策). He works hard at the image to allow himself the freedom he needs to do his work as a crime fighter. "Bruce Wayne, playboy" is the disguise Batman is the real person.
"Wayne is not a born superhero. Instead, he is a real, complex person," said Dace Golder, editor of the website. "He is the most realistic of all the superheroes. I am particularly interested in the emotional process by which a boy becomes a hero. His superhero qualities come from within."What is the article mainly about?
| A．How Bruce Wayne develops into a superhero. |
| B．How to overcome childhood fears. |
| C．What makes a superhero. |
| D．Why superheroes enjoy great popularity in Britain. |
