    5     signing of the agreement marks a new chapter in the strategic cooperation between the Palace Museum and Huawei Technologies Co. So Huawei will make efforts     6     (speed) up the intelligent construction of the Palace Museum.

“The 600-year-old Palace Museum has never been so close to science and technology.” Shan Jixiang said     7     (proud), former director of the Palace Museum.

Located in the north-east of Italy, Venice is known     1     "The Floating City". It is made up of over 100 small islands,     2     are connected by waterways and bridges. Unfortunately, water is also putting Venice in great     3    (dangerous). Saltwater is     4     ( slow) damaging the bases of Venice's buildings. The Floating City is, in fact,sinking.

More problems     5     (cause) by floods, which usually hit the city each winter. But these floods could now be a thing of the past thanks to a new flood prevention project.     6     (lie) in the middle of a lagoon, Venice was often hit by seawater caused by rain and strong winds every year, which travels through the     7     (nature) gaps to Venice.Dozens of gates have been built to hold back the sea until now. Each of these gates is 20 meters wide, with     8    longest about 30 meters long. In the event of a big rise in the water level, the gates will be raised to separate the city from the sea.

But only time will tell whether this project is the right solution. The important thing is that action is being taken    9    (protect) this unique city for future    10     (generation). And if it works, it means a longer, drier future for Venice.

We accessed the wall through the South Gate. The wall is 12 meters high and from here you can see streams of people moving inside and outside the City Wall.

After spending some time looking at all the defensive     4     (equip) at the wall, we decided it was time for some action and what     5     (good) than to ride on a piece of history!

We     6     (hire) our bikes from the rental place at the South Gate. My bike was old and shaky     7     did the job. It took us about 3 hours to go all     8     way around the Xi’an City Wall. Supposedly you can do it in two hours, but we stopped at the different gates and     9     (watchtower) to take pictures or just to watch the local people going about their     10     (day) routines.

Last week I had a holiday from work, but     1    (unfortunate) none of my friends had the same week off. I decided that I still wanted to do something, so I booked a train ride to Toronto and reserved a bed in a hostel for one week. One week by myself! Would I be bored? Quite     2     opposite! I was able to do whatever I wanted. I spent hours in museums,     3    would have seemed dull to my friends. I discovered my     4     (independent) and developed map-reading skills that I didn' t know I had. I could get up and go to sleep when I wanted and I didn't have to wait for anyone else     5     (get) ready every morning.

However, I found there were also some disadvantages of travelling alone. I missed     6     (have) someone to talk to. Experiences are often more     7     (enjoy) if they are shared. In addition, eating in a restaurant or cooking in the hostel     8     (be) less fun on my own.

I am very proud of myself for travelling alone and I had a good time in Toronto. However, in the future, I     9     (prefer) to travel with another person     10     in a small group.

It was my first day in Hangzhou, the Chinese city famous for its natural beauty and history and I didn't have much time to spare. I wanted to see     1     much of the city as possible in the two days     2     I was to return to Guangzhou. My first task was to decide where to go and     3     to get there. I took out my guide book in which there was a lot of information about the city's well-known tourist     4    (attract) and started to read. At that moment an attractive young lady     5     noticed my book, came up to me and introduced     6    (her). She said her name was Miss Bai. She kindly offered to show me     7     the city. I was delighted and was about to accept her proposal when she suggested we first     8    (go) to the West Lake and walk along the Broken Bridge. I quite liked the idea of visiting the West Lake but wasn't so sure about crossing the Broken Bridge.    9     it was broken, did she expect me to jump across？And I couldn't swim, so if I fell in then I would drown. That was definitely not an attractive idea so I politely declined her invitation,     10    (close) my book and walked away.
