The parks around the West Lake are perfect for visiting by bicycle or on foot. You can also go fishing and boating. The hotel is a five-minute walk from these beautiful parks. Children will love visiting the meandering walkways, old buildings and bridges, while adults can watch locals practice tai chi or drink tea at a nearby teahouse.Within the area is Zhongshan Park that was once the holiday home of Emperor Qianlong. There are also some gardens on several islands. You can also rent bicycles from the hotel and go bike riding around the lake.The visit to the West Lake is not complete without walking a few kilometers each on the famous Su and Bai Causeways(堤). The two causeways were named after two famous Chinese poets, Su Dongpo and Bai Juyi. Take a walk in the early morning, ride a bike or climb into a boat for a personal ride around the lake. Look for the stone carvings(石刻) left by Emperor Qianlong and these stone carvings tell you about the ten beautiful sights of Hangzhou.

It is about 45 miles away from Glasgow, 15 miles from Livingston and 100 miles from Carlisle and Aberdeen.During the Middle Ages, a small fort called Dun Eiden was built by the Gododdins. In the 7th century, the Angles invaded the fort. The Angles took the name “Eiden” and joined it to “burh”,an old English word meaning “fort”,and created the name of Edinburgh. It has been the capital of Scotland since 1437.If you come to Edinburgh by train from the south, the first thing you will see is Edinburgh Castle. It stands high over the city.Edinburgh is a city full of hills but it is a good city to visit on foot. After the castle, you can visit more of the Old Town. Go down the Royal Mile to Holyroodhouse. It is hundreds of years old. You can also go to the shops on the Royal Mile or on Princess Street in the New Town. There is also the National Gallery ofScotland, with pictures from Scotland and from many other places.In August, you can come to the Edinburgh International Festival. It's the biggest art festival in the world with hundreds of different things to do and see.63. What is Paragraph 2 mainly about?A. Where Edinburgh is.B. How Edinburgh got its name.C.

How to ask for directions abroad.B. How to give polite greetings abroad.C. Some examples of how landmarks are used.D. Some polite expressions about asking for help.EHave you ever wondered how you can politely ask a question in English? How should you ask your teacher for a day off? Using an indirect(间接的) question is one great way to do this.When to Use Indirect QuestionsWhen you ask a direct question, you ask directly, “Where is the bus stop?” Direct questions are fine when you are talking to your friends, family members or people you know well. But how should you ask if you are in a more formal(正式的)situation or if you are asking someone you're not really close to? What if you are in a party or a work convention(会议)? In these situations, it's politer to use an indirect question.How to Form(构成)Indirect QuestionsIndirect questions are questions with extra words and phrases(短语)to make your question softer:Is it possible…?Do you know…?I was wondering…Can/Could you tell me…?“Can” is a little more casual,__while “Could” is politer.When you use these extra phrases, the rest of your sentence will return to the normal word order(顺序)of a declarative sentence(陈述句).Other Ways to Ask Indirect QuestionsA good word to use in an indirect question is “if ”. You could say, “Do you know if there is a bookstore here?” People can answer these “if” questions with a simple yes or no!You can also use your polite phrase followed by a question word—who, what,where, when, why or how.70. How does the writer develop the text?A. By listing(列举) numbers.B. By giving examples.C. By answering questions.D. By explaining reasons.71. In which situation can you ask direct questions?A. When you are asking a stranger.B. When you are talking to your brother.C. When you are in a party.D. When you are at an important meeting.72. What's the purpose of the text?A. To ask for some help.B. To give teachers some advice.C. To teach students how to learn English.D. To tell us something about indirect questions.第二节:阅读下面的短文,并用英语回答问题(请注意每小题后面的词数要求)。
