But this definition of accents is limiting and could give rise to prejudice. Funnily enough, in terms of the language study, every person speaks with an accent. It is the regular differences in how we produce sounds that define our accents. Even if you don't hear it yourself, you speak with some sort of accent. In this sense, it's pointless to point out that someone “has an accent”. We all do!Every person speaks a dialect (方言) , too. In the field of the language study,a dialect is a version of a language that is characterized by its variations of structure , phrases and words. For instance, “You got eat or not?”(meaning “Have you eaten?”)is an acceptable and understood question in Singapore Oral English. The fact that this expression would cause a standard American English speaker to take pause doesn't mean that Singapore Oral English is “wrong” or “ungrammatical”. The sentence is well-formed and clearly communicative, according to native Singapore English speakers' solid system of grammar. Why should it be wrong just because it's different?We need to move beyond a narrow conception of accents and dialects—for the benefit of everyone. Language differences like these provide insights into people's cultural experiences and backgrounds. In a global age, the way one speaks is a distinct part of one's identity. Most people would be happy to talk about the cultures behind their speech. We'd learn more about the world we live in and make friends along the way.1.What does the author think of his/her friends' response in Paragraph 1?A.It reflects their self-confidence.B.It reflects their language levels.C.It misses the point of communication.D.It misses the real meaning of accents.2.Why does the author use the example of Singapore Oral English?A.To justify the use of dialects.B.To show the diversity of dialects.C.To correct a grammatical mistake.D.To highlight a traditional approach.3.What does the author recommend us to do in the last paragraph?A.Learn to speak with our local dialect.B.Seek for an official definition of accents.C.Appreciate the value of accents and dialects.D.Distinguish our local languages from others'.4.What can be a suitable title for this passage?A.Everyone Has an AccentB.Accents Enhance Our IdentitiesC.Dialects Lead to MisunderstandingD.Standard English Is at RiskB2023ꞏ南京市、盐城市模拟说明文309词★★★☆☆Among my friends, one topic seems to dominate their conversations: bones. It makes sense, given that 20 percent of American women over 50 have osteoporosis (骨质疏松) and that more than half have bone loss. For men, the figures are lower: 4 percent and a third. Worldwide, one out of three women over 50 and one out of five older men will develop a fracture (骨折). Another reason for the endless argument about bone problems is mass confusion over how to strengthen your bones best and whether diet really makes a difference.Diet research is always messy, and study results on nutrition and bone health haven't been consistent. But__gradually__some__clarity__is__emerging. As we draw up resolutions for what to eat, it's useful to look at new data on vitamin D. Calcium is the key element for building bones, and vitamin D helps to absorb calcium from the food we eat, so doctors often recommend D supplements (补充物) to make up for age-related bone loss.But a recent study found that taking D supplements for five years did not reduce the rate of fractures in seniors. That result built on earlier findings, led by the same team, that these supplements do not improve bone density (密度). “Food and sun exposure likely provide enough vitamin D for healthy adults,” says Mery LeBoff, who led the study.What does help maintain strong bones for all of us? The easy answer is food high in calcium, such as milk and tofu. “Getting it from food is best,” LeBoff says, “because there are so many other nutrients (营养物), and you have more continuous absorption than from Dsupplements.”The other key element of bone health involves calories out rather than calories in. Weight-bearing exercise stimulates bone formation throughout life. So while focusing on better nutritional choices, add more exercise to your daily menu.5.What do the statistics in Paragraph 1 emphasize?A.The seriousness of bone problems.B.The concern about senior citizens.C.The confusion about strengthening bones.D.The importance of having a balanced diet.6.What does the underlined sentence in Paragraph 2 imply?A.Diet research is no longer a challenge.B.We've made resolutions to study diets.C.Findings on bone health prove to be similar.D.We begin to agree on ways to keep bones healthy.7.What can be inferred from the recent study?A.People can absorb vitamin D in food easily.B.The findings go against LeBoff's earlier ones.C.D supplements play a minor role than expected.D.Fractures are linked with weight-bearing exercise.8.What is a suitable title for the text?A.Recipes for better bonesB.Your bones cry!C.The magic of D supplementsD.Vitamin D wins!答题策略语法填空——代词代词的应用与少用应①认清代词指代对象,注意前后人称要一致用②认清代词指代对象,注意前后单复数要一致③认清代词指代对象,注意前后性别要一致④this,that,it的应用;something和everything的应用;so和such的应用;反身代词与人称代词的应用;形容词性物主代词与名词性物主代词的应用;人称代词和物主代词的应用;人称代词的主格和宾格的应用,注意它的区别和运用少用 ⑤ 物主代词或人称代词的少用⑥ 留意无冠词、无物主代词、无不定代词修饰的名词参考答案Ⅰ.语法填空【语篇解读】本文主要介绍了河北省南韩村的基本概况及当地在传统手工艺方面的探索,该探索的目的是开辟一条适宜生活、工作和旅行的美丽乡村新道路。

2.阅读下面短文,在空白处填入1个适当的单词或括号内单词的正确形式。 Scientists say crocodiles have outlived dinosaurs ________some 65 million years. One reason why they are such good ________ (survive) is that they can go for a very long time without eating. And they are expert hunters,________(use) their strong jaws to bite their prey(猎物) and then swallow it whole. When they lose a tooth they grow one right back. A crocodile can go through 8,000 ________(tooth) in one lifetime! What does the expression "crocodile tears" mean? Simply put, "crocodile tears" are fake sadness. You pretend ________(cry) and feel bad for something when in fact you could not care ________(little). A great word to describe it is insincere. The phrase "crocodile tears" comes from an old myth that crocodiles would shed tears while eating their prey. A religious worker wrote that ________ a crocodile found a man by the water, it would kill him if it could. Then the crocodile would cry tears on the man, but then finally swallow ________(he). Another myth suggests ________crocodile is very clever indeed. Crocodiles, the story goes, would cry tears as a false show of guilt or sadness to trick their prey. The prey would come closer and then become dinner. Scientists explain that crocodiles DO create tears, but they do not cry. The tears help to clean their eyes. Crying is purely emotional and it ________ (reserve) for us humans. 【答案】 by;survivors;using;teeth;to cry;less;if/when/once;him;the;is reserved 【解析】【分析】本文是一篇说明文,解释了短语“鳄鱼的眼泪”的含义,它表示虚假的悲伤。科学家解释说,鳄鱼的确会流泪,但它们不会哭。眼泪有助于清洁他们的眼睛。哭纯粹是感情用事,是人类的天性。 (1)考查介词。句意:科学家说,鳄鱼比恐龙寿命长约6500万年。outlive by固定短语,“比……寿命长”,故填by。 (2)考查名词。句意:它们是如此优秀的幸存者的一个原因是它们可以长时间不吃东西。根据上文good为形容词修饰名词可知应填名词survivor“幸存者”,且主语they are可知应填复数形式,故填survivors。 (3)考查非谓语动词。句意:它们是专业的捕猎者,用它们强有力的下颚来咬它们的猎物,然后把它整个吞下去。本句中use做非谓语动词,与逻辑主语they构成主动关系用现在分词,故填using。
