10．Dear Linda，
I have been in England three months now．I hope you don't think I've forgotten you．There have been so many places to see and so many things to do that I've not had much time for writing letters．
I shall soon be starting my studies at King's College．So far I've been learning about England and British ways of living．I won't tell you about London．There are plenty of books you can read and plenty of pictures you can look at．I'm sure you'll be more interested to know what I think about the life here．
I find some of the customs new and interesting．People here do not shake hands as much as we do in Europe．During the first few weeks I was often surprised because people did not put out their hands when I met them．Men raise their hats to women but not to each other．
Your's
Alice

18．What's the most popular school activity for American students？The answer is the school dance．
   Most American high schools have at least two dances during the year，one in winter and the other in spring．Students take part in these dances because it's a great chance for them to meet new friends and to be sociable（好交际的）．At the school dance，students are from all grades and classes．
    Can all students take part in the school dance？The answer is"No"．At the school dance，there will be strict rules to help create a healthy and enjoyable evening for the students．
    Most schools only accept dancers under 21years old．And in order to create a safe environment，all the dancers will be given a check before they go into the dance area．This is acceptable．But some rules may be a little bit over the top．For example，a school once asked its students to keep a standing position while they were dancing．
    As a result，the students didn't have the chance of showing their cool dancing skills．However，you'd better not break the rules or you'll be asked to leave the dance floor，or even worse，be put on a"do not invite"list．

判断正误，正确的写T，错误的写F．
76．The school dance is the most popular school activity for British students．F
77．If someone breaks the rules of the school dance，the worse result is that he or she cannot take part in the school dance any more．T

15．Spring is here，the colourful flowers are seen everywhere but it is pity that many of us are not able to smell them while enjoying the colourful flowers？
Growing levels of air pollution from the factories and cars have reduced flower fragrances（芳香） by up to 90percent in the US，compared with pre-industrial levels 100years ago．
But if the trend is simply unpleasant for human noses，it may be life-dangerous for bees and butterflies．
Many insects find flowers by following the scent produced by those flowers．
The increasing pollution makes it difficult for them to find the flowers and feed on their nectar（花蜜）．
Scientists have already found that flowers produce scent molecules（气味分子） that mix with polluted things，which breaks down the plants'sweet smell．
With more pollution in the air，the scent molecules don't remain powerful as long and travel shorter distances on the wind．In the mid-19^th century，when pollution levels were first recorded，scent molecules would have been able to travel some 1，000to 1，200meters．Today，in the polluted air of large cities，scents may only make it some 200to 300meters．
Also，pollution from polluted air may fool the bee's"nose"，making their search for flowers all the more difficult．
In a paper published recently in Scientific Reports，scientists said that the nitric oxide（NO） and nitrogen dioxide （NO2）in polluted air could change many chemicals that work together to give a flower its special smell．
This，researchers said，"could prevent honeybees from reaching their flowers and prevent the pollination（授粉） of some of the world's food crops．"Or，this could put in danger agricultural harvests worldwide．
But the bees seem to have learned to get used to the changing world．"In nature honeybees use their special eyes and flower smell to find out where a flower is for the first time，"the researchers said．
57．According to the article，researchers have recently found thatB．
A．reduced flower fragrances have resulted in the dying out of many bees and butterflies
B．reduced flower fragrances are connected to growing levels of air pollution
C．polluted things in the air prevent flowers from producing scent molecules
D．flowers today can't produce enough nectar because of air pollution
58．What do the underlined words"the trend"in Paragraph 3refer to （指的是）？B
A．Increasing air pollution
B．Reduce flower fragrances．
C．Human beings'worse sense of smell
D．A growing number of power plants and cars
59．The scent molecules a plant produces are mainly toC．
A．help flowers to produce nectar
B．prevent insects from eating the plant
C．draw attention from bees and butterflies
D．clear up polluted things in the air
60．We can infer（推断） from the article thatB．
A．future food crops won't depend on bees to complete their pollination
B．some bees have successfully get over the challenge of reduced flowers fragrance
C．bees have great advantages in their senses compared to humans．
D．world food crop production is likely to fall greatly in the near future．
