文数，全国大联考2016届高三第三次。有答案的话要大题详解，没有答案的话帮忙解一下这两个题
19、1）、2Sn=3An-4,
2S(n+1)=3A(n+1)-4=2(Sn+A(n+1)),化简可得
An(n+1)-1=3(An-1)，a1-1=2-1=1，则An-1为等比数列，q=3
An-1=1*3^(n-1)
2)、Bn=n/(3^(n-1))，求和使用错位相减法
Sn=1/3+2/9+3/27…+n/3^n
Sn/3=1/9+2/27…+(n-1)/3^n+n/3^(n+1) 两式相减，得
2Sn/3=1/2-1/(2*3^n)-n/3^(n+1) →Sn=3/4-1/[4*3^(n-1)]-n/2*3^n
17、1）、求通项：就用等差数列的一般式：an=a1+（n-1）d代入求解
an=1+3（n-1）=3n-2
2）、bn=1/（3n-2）*（3n+1）可以进行因式分解：
bn=1/3 * 【1/（3n-2）-1/（3n+1）】，求和就简单了吧
Sn=1/3*[1-1/4+1/4-1/7+.............+1/(3n-5)-1/(3n-2)+1/(3n-2)-1/(3n+1）]
=1/3*[1-1/(3n+1）]
=n/(3n+1)
全手打，好累！

The Mobile Phone Throwing World Championships are held every year in Finland, the birthplace of the first
mobile phone. When the championships first took the place in 2000 there were only 30 competitors, but now the
championship attract well over 100 people from around the world. All of them are angry about one of the past
century蒺s most influential invention.
The competition is dividing into two sections, contested by teams and individuals. The original category is
judged simple on length of throw, but in the freestyle event competitors win on points awarded for notable
performances during the run -up. Though some competitors use their own handsets, but most take the mobile
phones from a large range of second-hand phones which are supplied by the organizers.
The competition is founded by local businesswoman Christina Lund.“I saw that all of us have very different
emotions about their mobiles: much of the time they cause tension and frustration to us, especially which they get
dropped. They never ring when they are supposed to and they go off at inconvenient times. So I had the idea of a
competition based 夷releasing some of that tension.”

A) One possible version:
Dear Principal,
I would like to recommend my English teacher Miss Jones for the Outstanding Teacher Award.
She has taught us for two and a half years. We know a lot about English and we like English so much
because of her teaching. The award should be given to her because she never gets angry or impatient with us, no
matter how many times we ask her for help. Also, she has a special way of making her lessons lively. She can
always make the complicated and boring grammar simple and interesting.
We all feel she loves us very much and we like her too. So I think we should show her how much we
appreciate her by giving her this award.
Yours faithfully,
Zhu Jun
- 12 -B) One possible version:
Never judge a book by its cover
I totally agree with this saying.
There is no doubt that the first impression is really important to some extent. It蒺s common sense that one
should go to great lengths to look their best when interviewed, for the sake of the first impression.
However, it蒺s universally recognized that it蒺s one蒺s inner quality that counts not only in family life but also in
one蒺s job. Those who are honest, helpful, strong-willed, tolerant, competitive, humorous ... are welcome. On the
contrary, people with an attractive appearance can always have things in their favour at the beginning but
gradually people tend to identify with those with outstanding abilities and improved qualities. Meanwhile, too much
emphasis on appearance can waste a life, with time spent on cosmetic surgery and chasing famous brands.
In conclusion, on no account should we judge a book by its cover.
