What is the difference between Free Trade Area and Customs Union？

A great difference between American social customs and those of other countries is the way in which names are used. Americans have little concern for “rank”, especially socially. Most Americans do not want to be treated in any especially respectful way because of their age or social rank; it makes them feel uncomfortable. Many Americans even find the terms “Mr.”, “Mrs” or “Miss” too formal. People of all ages may prefer to be called by their first names. “Don’t call me Mrs Smith. Ju call me Sally. ” Using only first names usually indicates friendliness and acceptance. However, if you do not feel comfortable using only first names, it is quite acceptable to be more formal. Just smile and say that after a while you will use first names but you are accustomed to being more when you first meet someone.

Very often, introductions are made using both first and last names: “ Mary Smith, this is John Jones. ” In this situation you are free to decide whether to call the lady “Mary” or “Miss Smith”. Sometimes both of you will begin a conversation using last names, and after a while one or both of you may begin using first names instead. You have a choice: if you don ’t want to use first names so quickly, no one will think it impolite if you continue according to you own custom.

In the first paragraph the author tells us that__________

A.Americans do not talk about rank, especially socially

B.Americans feel uncomfortable when talking about rank

D.Americans don’t care much about social rank

According to the passage, most Americans feel_________ when they are treated especially respectfully owing to their age or social rank.A.sick

Which of the following statements in NOT true?A.The way names are used in America is different from those of other countries.

B.Many Americans are used to being called by their first names.

C.It shows friendliness and kindness to use only first names.

B.she prefers to be called “Sally”

C.she is not Mrs Smith

5. Congress vs Parliament The difference between congress and parliament exist in the way they function. Congress and parliament are terms that have come to represent two major forms of democracies in different parts of the world. While Westminster form of parliamentary democracy is found in Britain and many other commonwealth countries that were ruled by Britain at one point of time and are now free and independent, congressional form of democracy where the President is the head of the executive is opted by mainly US and some other countries. The main purpose of both congress as well as parliament is to make, pass, and amend laws providing representation to states or provinces that collectively make up the nation. However, there are also differences that will be highlighted in this article. At a superficial level, it seems hard to find out differences between a congress and a parliament as both are made up of popularly elected representatives of people who have got majority votes of the people in their constituency. However, there are differences between both in how members get elected and what their roles and functions are once they are members of the house. The first and foremost difference between the two lies in the meanings of the two terms themselves. While congress comes from a Latin word meaning “to come together,” parliament comes from a French word meaning “to talk.” The same difference in meaning almost defines differences in the election procedure of congressmen and parliamentarians. What is the difference between Congress and Parliament? Both congress and parliament serve the same purpose of making legislations though, there are differences in how members get elected and what they do after getting elected in the two types of legislative bodies. Definition of Congress and Parliament: ? Congress is the legislative branch of a governing system that has a congressional democracy. ? Parliament is the legislative branch of a governing system that has a parliamentary democracy. Accountability of the Executive: ? The executive branch is not accountable to the legislative branch in a congressional democracy. ? The executive branch is accountable to the legislative branch in a parliamentary democracy. Freedom: ? There is more freedom to members in a congress than in the parliament. This simply means that a member has more individuality in case of congress than in the case of a parliament. Parts of Congress and Parliament: ? Congress has two parts as Senate and House of Representatives. ? Parliament has two parts as House of Lords and House of Commons. Influence of the Executive: ? Executive is more powerful in congress. ?However, executive is more in control as far as legislation process is concerned in parliament. 9. About the differences between Congress and Parliament, which one is NOT TRUE?

A、Members in a congress enjoy more freedom than in the parliament

B、Congress has two parts as Senate and House of commons.

C、Executive is more powerful in congress.

D、Congress comes from a Latin word meaning “to come together”.

The difference between a liquid and a gas is obvious under the conditions of temperature and pressure commonly found at the surface of the Earth. A liquid can be kept in an open container and fill it to the level of a free surface. A gas forms no free surface but tends to diffuse(扩散)throughout the space available; it must therefore be kept in a closed container or held by a gravitational field, as in the case of a planet's atmosphere. The distinction was a prominent feature of early theories describing the phases of matter. In the nineteenth century, for example, one theory maintained that a liquid could be" dissolved" in a vapor without losing its identity, and another theory that held the two phases are made up of different kinds of molecules. liquids and gases. The theories now prevailing take a quite different approach by emphasizing what liquids and gases have in common. They are both forms of matter that have no permanent structure, and they both flow readily. They are fluids.

The fundamental similarity of liquids and gases becomes clearly apparent when the temperature and pressure are raised somewhat. Suppose a closed container partially filled with a liquid is heated. The liquid expands, or in other words becomes less dense; some of it evaporates. In contrast, the vapor above the liquid surface becomes denser as the evaporated molecules are added to it. The combination of temperature and press at which the densities become equal is called the critical point. Above the critical point the liquid and the gas can no longer be distinguished; there is a single, undifferentiated fluid phase of uniform. density.

Which of the following would be the most appropriate title for the passage?

A．The Properities of Gases and Liquids.

B．What Fluids and Gases Are Made of.

C．New Uses for the Gas and the Liquid.

Call American Their names

A great difference between American social customs and those of other countries is the way in which names are used. Americans have little concern for "rank", especially socially.
