                                        Different school year in US and Cluna

    With the beginning of the new semester, we have to say goodbye to the summer holiday.  But do you

 know students in America start their semester earlier than we do?

    Most American schools have a total of about 180 days of teaching.  The fall semester goes from early

 September to mid-December, and the spring semester goes from early January to mid-June.

     In China, we have two semesters and each has about 20 weeks.  The US school year is about 20 days

  shorter than it is in China.

    In the US, school kids have a long summer vacation and a few breaks,  which are like China's Golden

 weeks. One is around Christmas, lasting about two weeks. Another is in February, for only one week. It

 can also be called "ski week", because some students go skiing during the break. And there is a

 one-week-long spring break.  It is in March or April, around Faster.

     Throughout the vear, there are also a few other holidays when students don't go to school, such as

 Thanksgiving Day.  This is similar to Mid-Autumn Festival in China.

     Now we can understand why American students start, school earlier than us at this time of year.

1. Spring semester in America is from _____ to _____.

2. Fall semester in American school year is from _____ to _____.

3. There are there breaks, there, One is _____ .another is one-week-long spririg break, either in _____.

4. There are a few holidays when students don't go to school, such as _____.

5. Thanksgiying Day in the USA is similar to _____ in China.

请回答下列问题:

(1)仪器中装入的试剂:B()、C()、D(),

(2)连接好装置后应首先(),其方法是();

(3)“加热反应管E”和“从A中逐滴滴加液体”这两步操作应该先进行的是在这两步之间还应进行的操作是();

(4)反应过程中G管逸出的气体是(),其处理方法是();

(5)从实验中测得了下列数据

①空E管的质量a

②E管和WO3的总质量b

③反应后E管和W粉的总质量c(冷却到室温称量)

④反应前F管及内盛物的总质量d

⑤反应后F管及内盛物的总质量e

由以上数据可以列出计算W的相对原子质量的两个不同计算式(除W外,其他涉及的元素的相对原子质量均为已知):

计算式1:Ar(W)=();计算式2:Ar(W)=()。
