英专综合教程6册课文翻译及课后答案Answer to unit3

IV. Chinese Translation of Paragraphs1. 首先,我要强调的是,读书本应是一种享受。

当然,为了应付考试或者获取信息,许多书我们不得不读,而我们从中却不可能得到任何愉悦。

我们读这些书是出于教育的目的,至多希望自己对它的需要不至于使阅读的过程过于乏味。

我们读这些书并非好之乐之,而是出于无奈。

这当然不是我要谈的读书。

要谈的读书。

我接下去要谈论的书籍,既不能助您获得学位,也不能帮您谋生;既不能教您怎样驾驶帆船,也不能教您怎样启动熄火的车辆。

然而,它们却可以让您生活得更为充实。

不过,您必须喜欢读书才行,否则也无济于事。

2. 我这里所说的“您”,是指那些有闲的成年人,他们想读的不是非读不可的那些书。

我指的不是书虫,因为书虫们自有读书之道。

我这里只想谈些名著,那些很久以来广受推崇的杰作。

我们理应都读过这些名著,遗憾的是这类人却为数甚少。

有些名著不仅为优秀的批评家们所公认,文学史家也会有长篇大论,然而,今天的普通读者读之却味同嚼蜡。

这些作品对研究者来说是重要的,然而,时移事易,人们喜好变更,如今这些书早已失其原味,要读完全凭意志。

举例来说,我读过乔治·艾略特的《亚当·比德》,但我不能违心地说这个过程是愉悦的。

我读它是出于义务,读完了自然如释重负。

3. 关于这类书籍,我无意置喙。

每个人自有自己的评价和意见。

不论学者们对某本书作何评价,即便他们众口如一,极尽溢美之词,除非您感兴趣,否则它与您毫不相干。

不要忘记批评家也经常犯错,批评史上那些最著名的评论家的低级错误比比皆是。

一本书对您价值几何,只有作为读者的您才是最终评判人。

当然,这适用于我将要向您推荐的书籍。

我们每个人都不可能与他人完全一样,至多只是相仿而已。

因此,没有理由认为对我有益的书也正好对您有益。

不过,读这些书让我觉得内心更加富有;倘若我没有读过的话,恐怕我就不会完全是今天的我了。

所以我恳求您,倘若您在本文的诱惑之下去读我推荐的书,但却又读不下去,那就放下它们。

Smartphones, tablets, and computers have become integral parts of daily life. However, this increased screen time has raised concerns about its impact onchildren’s sleep patterns. A recent study investigates the correlation between screen time and sleep quality in adolescents.Body:The study involved 1000 adolescents aged 13 to 16. Participants were asked to keep a sleep diary for one week, detailing their screen usage before bedtime. Researchers found that those who used screens for more than two hours before going to bed had significantly lower sleep quality than those who did not. The study also revealed that the type of screen used had no significant impact on sleep quality, suggesting that it’s the overall screen time that matters.One of the key findings was that the blue light emitted by screens can interfere with the production of melatonin, a hormone that regulates sleep. This disruption in melatonin production can lead to difficulty falling asleep and staying asleep throughout the night.Conclusion:The study concludes that limiting screen time before bedtime is crucial for maintaining healthy sleep patterns in adolescents. Recommendations include setting a “screen-free” hour before bedtime and ensuring that screens are turned off at least an hour before going to sleep.Questions:1.What is the main focus of the article?A. The benefits of technology in children’s educationB. The impact of screen time on children’s sleepC. The role of smartphones in daily lifeD. The importance of melatonin in sleep regulation2.According to the study, what is the primary factor affecting sleep quality in adolescents who use screens before bedtime?A. The type of screen usedB. The amount of screen timeC. The time of day the screen is usedD. The content viewed on the screen3.What is the recommended action to improve sleep quality in adolescents according to the study?A. Increase screen time before bedtimeB. Use screens only during the dayC. Turn off all screens at least an hour before bedtimeD. Limit screen time to one hour before bedtimeAnswers:1.B2.B3.C三、完型填空(15分)III.Cloze Test (Finish the following passage by filling in each blank with the correct form of the words given in the brackets.)(10 points)Directions: Read the following passage and fill in the blanks with the appropriate forms of the words given in the brackets.

锻炼练习题英语一、阅读理解阅读下面的短文,然后根据短文内容回答问题。

Physical exercise is important for maintaining a healthy body. It helps to strengthen our muscles, improve blood circulation, and keep our weight under control. Additionally, regular exercise can also have a positive impact on our mental and emotional well-being.When we engage in physical exercise, our body releases endorphins, which are often referred to as "feel-good" hormones. These hormones can help to reduce stress and anxiety, as well as improve our mood. Therefore, exercising regularly is not only beneficial for our physical health but also for our mental health.There are various forms of exercise to choose from, and it's important to find activities that you enjoy and are suitable for your fitness level. If you're new to exercise, start with gentle activities like walking or swimming. Gradually increase the intensity and duration as you become more comfortable.In addition to the physical and mental benefits, exercise can also provide an opportunity for social interaction. Joining a sports team or participating in group exercise classes can help you meet new people and build relationships. This social aspect of exercise can further contribute to our overall well-being.It's recommended to aim for at least 150 minutes of moderate-intensity exercise or 75 minutes of vigorous-intensity exercise per week. However,any amount of exercise is better than none. Even short bursts of physical activity throughout the day can make a difference.In conclusion, regular exercise offers numerous benefits for both our body and mind. It not only helps to keep us physically fit but also improves our mental well-being. Therefore, it's essential to make physical exercise a part of our daily routine.1. What are some benefits of physical exercise?Answer: Physical exercise helps to strengthen muscles, improve blood circulation, keep weight under control, reduce stress, reduce anxiety, improve mood, and provide social interaction opportunities.2. How can exercise benefit our mental health?Answer: Exercise releases endorphins, which are "feel-good" hormones. These hormones can reduce stress, anxiety, and improve mood.3. What types of exercise should beginners start with?Answer: Beginners should start with gentle activities like walking or swimming.4. How can exercise contribute to our overall well-being?Answer: Exercise provides an opportunity for social interaction, which can help build relationships and improve our overall well-being.5. How much exercise is recommended per week?Answer: It is recommended to aim for at least 150 minutes of moderate-intensity exercise or 75 minutes of vigorous-intensity exercise per week. However, any amount of exercise is better than none.二、完形填空阅读下面的短文,从每个空格处所给的四个选项中选择一个最佳选项。

In terrestrial plants, gasexchange takes place through leaves, stems and roots.In leaves, gases from the environment diffuse into the air space through the stomata. Gases dissolve in the moist surface of the mesophyll cells. They then diffuse to the neighbouring cells. 1m Gases diffuse from the leaves to the environment in the reverse way.In woody stems, gas exchange takes place through the lenticels. 1m In roots, gas exchange takes place all over their surfaces. 1m Water and minerals:The water potential of the soil water is usually higher than that of the cytoplasm of the root hairs, water moves into the root hairs by osmosis. 1m Water passes across the cortex from cell to cell by osmosis or moves along the cell walls.1m Water is drawn up the xylem vessels by transpiration pull. 1m Most minerals are absorbed into the root cells by active transport.

Exercise:
(1)
As oil is found deep in the ground its presence cannot be determined by a study of the surface. Consequently,a geological survey of the underground rock structure must be carried out. If it is thought that the rocks in a certain area contain oil, a "drilling rig" is assembled. The most obvious part of a drilling rig is called "a derrick". It is used to lift sections of pipe, which are lowered into the hole made by the drill. As the hole is being drilled,a steel pipe is pushed down to prevent the sides from falling in. If oil is struck a cover is firmly fixed to the top of the pipe and the oil is allowed to escape through a series of valves.
由于石油深埋地下,靠研究地面,不能确定石油的有无。

因此对地下岩层结构必须进行地质探测。

如果认为某地区的岩层含石油,则在该处安装“钻机”。

钻机中显眼的部件叫“井架”。

井架用来吊升分节油管,把油管放入由钻头打出的孔中。

当孔钻成时,放入钢管防止孔壁坍塌。

如发现石油,则在油管顶部坚固地加盖,让石油通过一系列阀门流出。

(2)
传真机在我国的使用已十分普及,并已成为重要的现代通讯终端设备。

据估计,2002年中国市场对传真机的需求量为200万台,国内产量仅能满足约30%的需求,进口机将占据市场的主导地位。

目前国内市场上的传真机90%以上是进口货,其中80%来自日本。

面对这种情况,国内已有20多家生产企业组装生产传真机,并开始投放市场。

上海理光传真机公司生产的产品已经开始返销日本,并已开发出一种具有无纸接收功能的新颖传真机。

Fax machines have been widely used in China as a popular and important modern telecommunications terminal equipment. It is estimated that China needs 2 million fax machines in the year 2002,but the country can only satisfy about 30% of the demand with the market being dominated by the imported ones.
At present,more than 90% of the fax machines in China's market are imported from overseas,80% of which are from Japan. To deal with such a situation,more than 20 home plants have begun to assemble and produce fax machines,and homemade machines are being put in the market. The Shanghai Ricoh Fax Machine Company has begun exporting its products to Japan and has developed a new model that can receive information without paper.。
