People from different countries view time differently. Take Mongolians, for example. They fresh grass for their animals. Due to the seasonally move from place to place, searching 1 extreme weather and the rough ground, it takes time to move around. The more quickly circumstances change, 2 their trips become. So, they adopt flexible schedules instead of strict ones. They often arrange appointments "before noon" or "at night" rather than set a certain time to meet. 3 they arrive within the specified period of time, they are considered "on time." 4 5 on a person is regarded as being However, this is very different from the practice in Japan, "late" if he or she shows up even one minute past the appointed time. This practice dates back to Japan's industrial revolution. At that time, factory employers demanded that employees time for shifts in order to meet tight production schedules. Apparently, people from different cultures view time in their own ways. Without a doubt, times may change, but culture runs deep. 1. (A) to (B) for (C) into (D) with 2.

看不懂老師的算式 有人能幫我拆解步驟解釋一下嗎 或是另外寫易懂的算式過程 拜偷

A sample containing 25.14g of neutral salts, glucose and a sodium carbonate/bicarbonate buffer was dissolved in 100 ml of water. A 25 ml aliquot of the resultant solution required 20.35 ml of 0.0987 M HCl when titrated to the PP end-point. A second 25 ml aliquot was titrated to the MO end-point and required 56.75 ml of the acid. Calculate the percentage of Na2CO3 (molecular weight 106) and NaHCO3 (molecular weight 84) in the sample. 含有25.14克中性鹽、葡萄糖和碳酸鈉/碳酸氫鈉的樣品將緩衝液溶解在100ml水中。需要25毫升等份所得溶液滴定至PP終點 時,使用20.35ml 0.0987 M HCl。第二份25毫升等分樣本是滴定至MO終點,需要56.75ml酸。計算百分比樣品中的Na2C03 (分子量106)和NaHCO3(分子量84) 39

求解第2、7題

10% Can money buy happiness? People have always wondered 1. money really makes them happy. Researchers used to believe that it is up to a certain point happiness increases with income: beyond an annual income of $75,000, people are no happier with higher salaries. 3., recent studies have indicated that happiness still increases when salaries are higher than $75,000. The main reason that money seems to bring happiness is 4. more money can bring greater financial security. Daily activities such as grocery shopping are easier when most of the anxiety regarding what 5. is removed. In this way, money could be viewed as a solution problems. 6. one's on individual Most studies related to this question are based on averages rather than experiences. 7., there are many exceptions to the rule that happiness increases with 8. making $25,000 per year. By contrast, one's income. Some people are satisfied others feel that millions of dollars are required 9. their desired lifestyles. Compared with averages, the individual items that people spend their money on may be truer measures of happiness. A few studies have indicated that people are happy 10. they spend their money on specific items. This suggests that although having all the money in the world may not make you happy, it would give you more choices in purchasing the items you want. Such choices could surely increase one's happiness. anw spalliv siff (D) whether ) 1.(A) where (B) who (C) what (A) 2)(A) that (B) when (E) how (D) which (A) 3.(A) However (B) Thus (C) Similarly (D) Moreover (C) 4.(A) who (B) why (C) that (D) where B) 5.
