5. Unit 5: Writing PracticeSample Essay:In recent years, the use of smartphones has become increasingly prevalent. They have transformed not only the way we communicate but also the way we live our lives. However, some people argue that smartphones have had a negative impact on our society. In this essay, I will present both the advantages and disadvantages of smartphone use.On the positive side, smartphones have greatly enhanced our ability to connect with others. With just a few taps on a screen, we can instantly communicate with friends and family around the world. This has made it easier to maintain relationships and stay connected, even when we are physically apart. Additionally, smartphones provide access to a vast amount of information. With internet connectivity, users can quickly search foranswers to their questions, making learning and problem-solving more convenient.Yet, there are also drawbacks associated with smartphone use. One major concern is the negative effect on interpersonal communication. People are increasingly engrossed in their devices, leading to less face-to-face interaction. This can result in a decline in social skills and a lack of genuine connections. Moreover, smartphone addiction has become a serious issue. Many individuals find it difficult to detach themselves from their devices, leading to decreased productivity and increased stress levels.In conclusion, smartphones have undoubtedly revolutionized our lives, bringing numerous benefits. However, it is important to recognize and address the potential drawbacks. Finding a balance between utilizing the advantages of smartphones while mitigating their negative impact is crucial. By doing so, we can fully harness the power of technology while preserving the essence of human connection.。

DictationBaseball is America's national sport, played mainly by men. It developed in the mid 19th century from the British games of rounders and cricket. Baseball is also popular in Japan and several Latin American countries, and has been an Olympic sport since in 1972. Softball is similar but uses a large, softer ball and is popular with women. Many Americans play baseball for fun because players do not have to be strong like football players or tall like basketball players. Some people think baseball is too slow, but the team managers often change their players and plans during the game, and there are many exciting plays. Many American families enjoygoing to a Sunday afternoon double-header, that is, two games between the same two teams in one day.翻译你能想像一个身体严重残疾的妇女独自经营一个网站并且像一个专业的体育记者一样详细报道洛杉矶道奇队吗?如果我没有亲眼见到她蜷曲在轮椅里,用固定在头上的一根棍子敲击字键打出她的评论,我是绝不会相信的。

He was unaccustomed to dilemmas(两难境界)like this which could not be reasoned out in a decent length of time,and he was g etting angry with himself.Moodily he turned into a cheerful-looking restaurant and h ad a lonely meal,aware that he might have Jenny's happy face across the table -- he was wasting time–but after so many years,did a few more hours matter?(珍妮和雷蒙德是情人,第二次世界大战前把他们分开。
