Recently I paid a visit to Harvard University, where there are top class scientists and professors and the best academic system in the world.

I was pretty   (1)  when I first stepped onto the campus. Well, itˈs not even really a campus. Itˈs  (2)  like a district in a small town.

Harvardˈs main buildings are from the 18th century, They look very old and   (3)  . You might   (4)  say theyˈre a little shabby. They donˈt fit the modern  (5)   of university at all. The buildings are surrounded by  (6)  and trees, so I felt as if I had walked into a medieval (中世纪的) castle. But when I looked across the street,   (7)  shops and in-fashion students made me feel like I was in the 21st century  (8)   . It creates a strong contrast and brings a special   (9)   to the school.

Our tour  (10)  Gary took us around and told us, "You see this grass field in the center of the school? Here is where they hold their  (11)   ceremony. They just set up tents and benches and have a very simple ceremony.” Itˈs   (12)   ! Who would think the most talented students just graduate on the grass?

I   (13)  some students put a blanket on the grass and lie down to read a book. When I listened to the soft sound of   (14)   turning, along with chirping of the birds, I felt very  (15)  . There was no competitive feeling at all.

Harvard has the worldˈs first computer in its science centre  (16)   there are hundreds of high-end computers, too. Its religion and the literature departments are also  (17)   the best. It is the perfect mix of tradition and   (18)   technology. It makes Harvard a very attractive place to  (19)  in. I hope one day Iˈll   (20)  my dream school -- Harvard.

When July comes, children know they’ll have their examination and the school year will end soon. Boys and girls will have a nearly two   (1)  holiday, and they’ll leave school   (2)    train or by car to     (3)    to see their fathers and mothers.The summer holidays are the      (4)     time of the year for most children. The weather is usually good, so one can    (5)   most of his time playing outside.    (6)   one lives in the country, he can  (7)     into the woods and in the fields. If one lives in a big town, he can    (8)   go to a park to play.

    The best place for a summer holiday is the    (9)    . Some children are   (10)    enough to live near the sea. But for   (11)    who do not, if they have the chance to stay at one of the big seaside towns for a week or two,    (12)   will talk about it all the following school year. Now,    (13)    makes the children like the seaside so much? I think it is the  (14)   , the sea and the sun, not   (15)   else. Of course, there are    (16)    new things to see, nice things to eat, and    (17)   things to do. But the feeling of the sand under their feet of the  (18)   water on their skin, and   (19)   of the warm sun on their backs make   (20)    happier.

      Eco-tourism involves people traveling to beautiful but environmental sensitive places. Such trips are   (1)  carried out with an experienced guide. Over recent years, this type of travel has been steadily gaining   (2)  as more people search for new travel experiences.

      Eco-tourism has many benefits. First, all the   (3)  spent by the tourists is used to   (4)  the important environmental spots they visit.  Second, it helps  (5)  to better understand the environment, thereby   (6)  their knowledge of the world. Furthermore, this style of travel is also more  (7)  of the local culture.

      Compared to  (8)  tourists, eco-tourists use energy more efficiently, save water and produce less rubbish by finding ways to   (9)  it. These behaviours have a  (10)  and lasting effect on the local environment.

      Two things are needed to make eco-tourism a/an   (11)  . First, it should be done in small groups. And second, because it requires considerable effort, both eco-tourists and locals must be   (12)  in their commitment to improving the environment.

      Green travel provides local people with jobs in parks,   (13)   and shops. One great achievement of eco-tourism has been the   (14)  of illegal hunting. Former hunters can now work as guides to help keep the animals   (15)   in their natural surroundings. Green travel also  (16)  local peopleˈs quality of life, especially childrenˈs.

      Peru is one country using eco-tourism to promote respect for the   (17)   . Itˈs now able to take better care of its rainforests because of a/an  (18)  on more sustainable(可持续的)travel.

        (19)  this, local peopleˈs living-standards have improved. Many others are now following Peruˈs   (20)  and using eco-tourism to preserve their environment for the future generations.
