In Western countries, you should be careful about the giving of gifts.Never give a gift in a job interview or at a business meeting.Gifts are usually given during special holidays, or as a “thank you” for special invitations or events.When arriving at a special party, you may give your gift to the host once the introductions are made.Here are a few rules.
Be modest with your gift.Don't buy gifts that are too expensive.
A special food from your country, a bottle of wine, candy, or flowers are the best if you do not know the host very well, but be sure that your gift will not need much care.You can usually say something like “I think you may like to try this a little later” when you offer your gift.
Be careful when giving alcohol.A bottle of wine is usually all right if you know your host drinks wine, but strong alcohol such as whisky should only be given as a gift when you know the host well and are sure that he would like such a gift.Flowers are good, but remember：roses are for special love.You have to be careful.
A small cultural gift from your country is usually very good.
Besides, make sure that your gift is packed nicely.A nice card with it will be even better. 阅读短文，判断正(T)误(F)。

3、甲和乙两种固体物质的溶解度曲线如图所示。℃时，甲和乙的溶解度相等；若要使一定质量 接近饱和的物质甲的溶液变为饱和溶液，可采用的方法 是(写一种即可)；t2 ℃时，将70 g甲物质的饱 和溶液稀释为溶质质量分数为10%，需加水g。 4、(2018·河南)如图是甲、乙两种固体的溶解度曲线。甲和乙的溶解度相等时的温度为℃，t2 ℃时，分别用甲、乙的固体配制相同质量甲、乙的饱和溶液，所需要水的质量关系为甲乙(填“大于”“小于”或“等于”)；t2 ℃时，将75 g甲的饱和溶液与50 g水混合后所得溶液中溶质的质量分数为。 5、甲和乙两种固体的溶解度曲线如图所示，20 ℃ 时，等质量的甲和乙的饱和溶液中分别加入等质量 的甲、乙固体。升高温度至40 ℃，发现甲固体减少， 乙固体增多，则甲的溶解度曲线为(填“A”或“B”)；40 ℃时甲、乙的溶液中含水较多的是； 40 ℃时向60 g甲的饱和溶液中加40 g水，溶液的质 量分数为。 6、如图是甲、乙两种固体物质的溶解度曲线。 甲和乙溶解度相等时的温度为________℃；分别将甲、 乙的饱和溶液从t1 ℃升温到t2 ℃，所得溶液的溶质质 量分数为甲________乙(填“大于”、“小于”或“等于”)； t3 ℃时，向x g甲的饱和溶液中加入100 g水得到20% 的溶液，则x＝______。

In his short life he wrote 31300 songs and an opera. Xian was born in Panyu, Guangdong, China in 1905. Because his father died before he was born, Xian moved from place to place with 32 mother. He began learning to play 33 violin when he was 20 years old. In the beginning, his violin was so cheap and badly made that he 34 not play it well. His friends laughed at him. Xian did not stop practicing and soon showed his talent. In 1934，he was one of the first Chinese students 35 studied in a special music school in Paris. Before he left, Xian became the school’s best student 36 won several prizes for his talents. In 1935，he returned to China and helped fight against the Japanese army. Later, he came to Yan’an 37 music at a college. Although there were no pianos in Yan’an at that time, Xian still wrote some of his most important music there, including The Yellow River, his most famous work. In May 1940, Xian 38 to the Soviet Union (苏联)by the Chinese Communist Party to write music for movies. In the Soviet Union, life was very 39 Xian got sick and later died of a lung (肺）illness 40 October 30,1945,aged only 40. Xian’s music, however, lives on in the people’s hearts. ( )31.
