Venice
Venice is famous throughout the world.People also call it the "Floating City" and the "City of Water" because the whole city is on the water--there are over 117 small islands and over 400 bridges in this city.One of the best ways to see the city is on a gondola --a traditional boat.

Gondola--- the best way to see the city
Taking a gondola ride through the canals of Venice can be very romantic,but it can also be costly.
A standard gondola ride is 40 minutes.If you negotiate for a lower fare.you'll end up with a shorter ride.Gondola fares are highter at night.A gondola holds six people and can be shared without affecting the fee.Therefore,you can save money by sharing it with several people.If you book a gondola ride through a hotel or agency,there's likely to be an additional fee.

Homework
1.以“What can we do to save water?”为题,提出节约用水的建议(至少6条建议)。
尽量使用限定词a lot of,a little,a few,(not) much,(not)many,no,too much,too many,too little,too few,(not)enough等。
