…… The alternative is a pick-and-mix social landscape. At the moment ethnic minorities are moving in different directions at different rates, with personal and social engagement across ethnic boundaries increasing all the time. One crude indicator is the level of mixed race marriage: one in five Bangladeshi and Pakistani men born in Britain now has a white wife, and one in five babies born in Britain has one Afro-Caribbean and one white parent. This implies a Britain in which people will construct multiple identities defined by all sorts of factors: class, ethnicity, gender, religion, profession, culture and economic position. It won't be clear-cut. Not all ethnic minorities, or members of an ethnic minority, will be moving in the same direction or identifying the same issues at the heart of their identities. It's about deciding who you are, but also about how other people define you. That's what will be at the heart of the next 50 years: enduring communities linked by blood through time versus flexible, constantly shifting identities. Identity won't be about where you have come from; it will be a set of values you can take anywhere that is compatible with full participation in whichever society you live in.

Revising can be described as the most important(and frequently most neglected) part of writing. Novelists Doris Lessing has said that many novels miss greatness because authors are unwilling or unable to revise them. James Michener explains the importance of revision this way: "I have never thought of myself as a good writer. Anyone who wants reassurance of that should read one of my first drafts. But I' m one of the world' s great revisers." Revising takes many forms. It means thinking about the audience for your writing. Who will read your work and why？ It also means developing an overall plan for the writing that will make your ideas clear. Often the organization of a first draft will reflect your process of discovery, but that may not be the best way to present your ideas to someone else. Revising also gives attention to the style. of language, to the structure of a paragraph, and to the shape of sentences and other forms that show learning to its best advantage. Writing to learn and writing to show learning are never, of course, entirely separate processes. Writers frequently consider issues of demonstrating learning while writing to learn, and writing to show learning often leads to new under- standings. In drafting, for example, you may start thinking about what an audience will need to know in order to under- stand your point and change a word or a phrase to make your meaning clearer. But understanding the differences between writing to learn and writing to show learning is central to seeing writing as a process. What Doris Lessing said helps to support the idea that______. A．he is one of the world' s great revisers B．he is not a good writer C．revising is very important D．many writers are unwilling to revise their works
