It is well known for its multicultural cuisine(菜肴) and its colonial architecture and is considered by most experts to be the birthplace of jazz, the one music style that the USA can lay claim to inventing.2．________The city was founded in 1718, at a time when France owned that part of North America. Part of its diversity results from the fact that it was subjected to many different influences. France sold Louisiana to Spain in 1763, got it back 40 years later, and almost immediately sold the territory to the USA.3．________As the city prospered(繁荣), it became a magnet(磁铁)for all kinds of immigrants from Europe and other parts of the USA, and was also the first choice destination of breed black slaves. The rich cultural mix led to a relaxed attitude to life and an appreciation of good food, wine, music and dancing. There were frequent festivals.4．________By the end of the 1700s, people of African descent(祖先) made up more than half the city's population. Many more arrived via the Caribbean and brought with them West Indian cultural traditions. By the mid-18th century, black New Orleans people were gathering socially on Sundays at a special market outside the city, where they were able to remember and practice their traditional African dance and drumming music. The roots of jazz can be traced to these events.5．________Native American musicians then combined their music with the African traditions and bandsplaying a mixture of styles began to perform in street festivals. Europeans came to listen and contribute and the roots of jazz were established. Louis Armstrong, the most famous jazz musician of all time, was influenced by these rich musical mixtures when he heard them in the early years of the 20th century.答案：1－5CABFDⅡ.阅读表达阅读下面短文，并根据短文后的要求回答问题(请注意问题后的字数要求)。

[1]It's safe, it's simple, and it works: Drinking right amounts of water really can help you lose weight, new research shows.[2]In what researchers claim is the first-ever trial of the effect of water consumption on weight loss, scientists from Virginia Tech found that dieters who started each meal with two glasses of water lost nearly five pounds more, on average, than dieters who did not, over the course of 12 weeks. There's no shortage of clear evidence about how water might work to control your appetite (食欲). It ________ so you don't eat so much; it keeps down your thirst so that you don't turn to calorie-rich sodas or juices. But until now, the researchers say, there has been no true evidence that water's appetite-controlling benefits ever translate into actual weight loss. Now there is. In the 12-week study period, dieters instructed to drink water with every meal lost an average of 15.5 pounds; dieters given no instructions lost, on average, just 11 pounds.[3]Perhaps the most surprising thing about the finding is how little we still know about healthy water consumption in general. In fact, although doctors and public health authorities regularly remind us to drink more water, very few studies give any insight into what our ideal quantity may be.[4]The new results today suggest that many people could indeed stand to drink a little more water than they do. But if you're looking to lose weight, be aware that it is actually possible to drink too much water, and you probably won't help matters any by drinking too much water at a time. In extreme cases, it can even be deadly. A couple of glasses with each meal, however, should be no problem at all for a healthy person.1．What is the main idea of the text？(no more than 8 words)________________________________________________________________________ 2．Complete the following statement with proper words.(no more than 2 words)Enough obvious evidence ________________ how your appetite might be under the control of water.3．Fill in the blank in Paragraph 2 with proper words.(no more than 3 words)________________________________________________________________________ 4．Why should we avoid drinking too much water at a time？(no more than 6 words)________________________________________________________________________ 5．What does the word “it” (Line 1, Paragraph 1) probably refer to？(no more than 6 words)________________________________________________________________________ 答案：1．Drinking water can help lose weight.2．has proved3．fills you up4．Because it might cause/lead to/result in death.5．Drinking right amounts of water.Ⅲ. 任务型读写阅读下面短文，根据所读内容在表格中的空白处填入恰当的单词。
