I took an international flight for New Zealand the past autumn.   (1)   I stepped out of the airport, I was impressed by the natural environment and attracted by the blue sky and unique plants in this _  (2)   country, where my unusual   (3)  _ began.

   I had applied a special visa, so I could enjoy great   (4)   when staying there. This freedom doesn't mean I could do anything I wanted, _  (5)   I could enjoy everything I did. It is easy to   (6)   life and work in New Zealand because every day is different.

   I picked fresh fruit in the thick forest,   (7)   wild fruit when the night came, _  (8)   sheep and chickens, planted flowers, painted a cottage and worked in a store   (9)   with balloons in the hall. I even climbed mountains,   (10)   waterfalls and played on the beach.

   I saw a lot of the North Island and would soon visit the South Island, which is said to be _  (11)  __ remote and beautiful. ___  (12)  __ is another thing worth mentioning. In a youth hostel, I met people from all over the world who could cook all sorts of food. ___  (13)  __ curiosity, I learned a lot of recipes and __  (14)  ___ different types of food, which most of the time was very delicious. In my __  (15)  _, nowhere else in the world can you enjoy __  (16)  _ food than here.

   From my __  (17)  _ in New Zealand I can conclude that the country is filled with _  (18)  _ food just waiting to be explored. As a saying __  (19)  _, "Spend any time in New Zealand, and you will get the feeling that God has only just finished his work." My mind goes that _  (20)  _ there were a Garden of Eden, it would certainly be in New Zealand.

One of the most exciting archaeological (考古的) discoveries in history was made in November 1922, when Howard Carter was  (1)   in the Valley of the Kings in Egypt. After many months of digging, he finally  (2)   an unknown tomb (坟墓).

  (5)  , because the tomb was  (6)  , and it was clear that it had been robbed (盗窃) at some time in the past.   (7)  , one of the workers eventually uncovered a small stairway that led down to another door that had not been

  (8)  .

  (12)   .The tomb of King Tutankhamun was full of treasures of   (13)   value. There were over 5,000 objects of silver, gold and precious stones which had lain there  (14)   for thousands of years.

Lord Carnarvon’s   (15)   at discovering the treasures did not last long. Many of the local people were afraid of   (16)   the kings’ tombs, and believed that the kings would punish anyone who   (17)   them. Lord Carnarvon had paid little attention to these   (18)  , but only a few weeks later, he   (19)   fell ill and died; at the exact time of his death, all the lights in Cairo went out all of a sudden, and far away in England, his dog also  (20)  .

Jack is a retired worker from Rio de Janeiro. Now he is sharing a   (1)   relationship with a penguin which is native toSouth America’s Patagonian region. For the past five years, the penguin seems to have   (2)   its natural migrating (迁徙) route just in order to be able to   (3)   

Jack several times a year.

The   (4)   friendship began in 2011, when Jack found the bird, nicknamed Jinling, trapped in oil on the beach near his house. He brought the penguin home,   (5)   him up, and offered him a good meal and a shady spot to rest in. Since then, the penguin has   (6)   stayed away from Jack for too   (7)  .

Even if the kind man tried to get the penguin to   (8)   the open sea after he got better, the bird just   (9)   coming back. He even took him out in a boat, far from   (10)   and let him loose in the ocean, but by the time he got back home, Jinling was already waiting for him.

  (11)   penguins migrate thousands of miles between breeding colonies in Patagonia and feeding grounds further north inRio de Janeiro, Jinling doesn’t   (12)    Riofor more than four months at a time. He always runs back to Jack’s little   (13)   by the sea, sometimes spending as long as eight months to a year with the old man. And he is a little   (14)  , too –– it seems that he can’t stand other animals getting anywhere close to his   (15)  .

The local fishermen show their   (16)   of the penguin and they think it’s a great   (17)   not only for Jack himself but also for all the villagers. Jinling has been regarded as the village mascot (吉祥物) since 2012.   (18)  , some are still confused by the   (19)   sight of Jinling walking along with Jack wherever he goes. But they think that penguins must know   (20)  they can repay humans’ kindness.

Many of us develop a desire to travel.   (1)  , few are lucky enough to turn that desire into a   (2)  career（职业，事业）. For Trish Sare, owner of Vancouver-based Bike Hike Adventures, Inc., it was a   (3)   story.

“I left home when I was 20 with a   (4)   of traveling the world for five years,” recalls Sare. “During that period, I spent a lot of time   (5)   adventure companies abroad and taking part in some of their adventures. Upon returning, I studied   (6)   and fitness leadership. Then, when we had to do our field placement（实习）, I   (7)   a tour agency. When they heard about my   (8)   , they asked if I wanted to go to Costa Rica for my placement and   (9)   as a tour leader. And that is where it all   (10)  .”

That beginning marked the accomplishment of a   (11)   dream for Sare. Today, she can   (12)   those exciting memories from such places as Thailand, Nepal, Costa Rica and more. Although Sare   (13)   her dream of traveling for many years, she began   (14)   something that offered just a little bit more. So, in 2014, she took the big   (15)   of starting her own company: Bike Hike Adventures Inc..

 Her career has   (16)   her all over the world to interact with people of so many different   (17)   and backgrounds. Looking back, Sare can   (18)   say that it’s been the right choice for her. Here’s her   (19)   for those wanting a similar path:

“Do some traveling   (20)   your own first and then you’ll be marketable to companies,” she concludes.

The most unforgettable thing during my long summer holiday last year, of course was my trip   (1)   England. This was my first time to go abroad, so it really made me   (2)  .

There are quite a lot of interesting places in England,   (3)   Oxford. When we walked around Oxford, we saw quite a lot of ancient buildings on   (4)   sides of the streets. One of the most famous tourist   (5)   in Oxford is Christ(基督) Church, and it’s   (6)   one of Oxford University’s 29 colleges. There is a huge hall in Christ Church,   (7)   was used as the dining hall at Hogwarts in the Harry Potter   (8)  .

I felt really excited when I heard this.

  (9)   place that impressed me   (10)   during my trip was a place called Stratford-upon-Avon. It is a small town. Maybe you haven’t   (11)   it, but I’m sure

you have heard about William Shakespeare and it’s the great man’s   (12)  . In Stratford-upon-Avon, I could   (13)   Shakespeare’s birthplace, Shakespeare Countryside Museum, the Royal Shakespeare Theatre, and a lot of places that are connected with   (14)  . 

I went to Shakespeare’s birthplace. It was the house   (15)   Shakespeare was born and   (16)   his early years.  (17)   sitting room, hallway(走廊), bedrooms, and kitchen were furnished(布置) in sixteenth-century   (18)  . I also went to see the Shakespeare Exhibition. It illustrated(以图解说明) Shakespeare’s life and career in both Stratford and London.

I really enjoyed this nice trip to England,   (19)   I learnt a lot. I’m very happy that I could visit such an interesting   (20)  . I want to go there again in the future.

crops can make the world a      51 place. If bioengineers can create crops that are resistant to insects,      52, then they won’t have to worry about insects destroying plants. In the      53of insect damage, crops can grow to feed the poor and hungry. Genetic engineering can create plants with other desirable properties as well. Plants that don’t require much water, that can live even in times of drought, can help prevent the widespread      54that would occur if people have nothing to eat.

People born in the autumn live longer than those born in the spring and are less likely to fall ill when they are older, according to an Austrian scientist. Using census(人口统计) data for more than one million people in Austria, Denmark and Australia, __36__ at the Max Planck Institute for Demographic Research in the northern German town of Rostock found the month of birth was _37__ to life expectancy（平均寿命）over the age of 50. __38__ differences in what mothers ate during pregnancy（怀孕）, and __39__ occurring at different times of the year could both have an _40_ on the health of a new-born baby and could __41__ its life expectancy in older age. "A mother giving birth in spring spends the _42_ phase (阶段)of her pregnancy in winter, when she will eat less vitamins than in summer," said Gabriele Doblhammer, one of a team of scientists who _43_ the research. "When she stops breast-feeding and starts giving her baby __44__ food, it’s in the hot weeks of summer when babies are likely to be exposed to infections of the digestive system（消化系统）." In Austria, adults born in autumn (October-December) lived about seven months _45__ than those born in spring (April-June), and in Denmark adults with birthdays in autumn outlived those born in spring by about four months. In the southern hemisphere（半球）, the picture was __46_. Adults born in the Australian autumn - the European ___47__ - lived about four months longer than those born in the Australian spring.
