【正文】 即可以單用的語素。（ 2）把語素分為“自由語素”和“不自由（黏著）語素”。自由語素指某種語素既可以單獨形成詞，有時又可以單獨說出來。因為是虛詞，所以永遠(yuǎn)不能單獨說出來，這就是黏著語素。（ 3）把語素分為“定位語素”和“不定位語素”。定位語素指的是在最小的合成結(jié)構(gòu)中的位置是固定的，或者總前置，或者總后置。不定位語素是在最小的合成結(jié)構(gòu)中位置不固定的語素，它們既可以前置，又可以后置。（ 4）把語素分為“實義語素”和“虛義語素”。實義語素就是有實在的詞匯意義，或說本身直接負(fù)載了詞匯意義的語素。虛義語素就是一般不具有實在詞匯意義的語素。 16. 簡答語素、音節(jié)與字符之間的關(guān)系。 答：語素、音節(jié)與字符間有著較為密切的關(guān)系。漢語中語素大多數(shù)是單音節(jié)形式，書面上用一個漢字記錄，三者之間有一種對應(yīng)關(guān)系。一般而言，一個語素就是一個音節(jié)，一個漢字。但是語素、音節(jié)、漢字又屬于不同的范疇，語素是語匯單位，音節(jié)是語音單位，字是文字單位，因此將三者合起來看，就不成簡單的對應(yīng)了。 Visafree policy brings Chengdu biz, tourism boost. Making national headlines several times, Chengdu39。s 72hour visafree policy has attracted wide attention from both Chinese and foreign experts and businessmen since it took effect on Sept 1 last year. The program permits citizens from 51 countries and regions including the United States, Australia, Canada and Japan who have valid visas and flight tickets to a third country to spend three days in the city. The capital of Sichuan province is the first city in the western region of China to offer foreign tourists a threeday visa and the fourth nationwide to adopt the policy following Shanghai, Beijing and Guangzhou. Li Zhiyong, deputy dean of the tourism institute at Sichuan University, said the move contributes to a large increase in the number of overseas tourists and raises the city39。s level of internationalization. The policy will also bring direct economic revenue, Li said. Chengdu has many cultural legacies and is also a paradise for panda lovers with the world39。s largest breeding and research center. Three days are long enough for foreign visitors to visit those iconic tourist spots, he noted. The city is home to the remains of the Jin sha civilization that dates back more than 3,000 years as well as the Qing cheng Mountains and the Du jiang yan irrigation system. Qing cheng has long been recognized as the birthplace of Taoism, China39。s ancient indigenous religion, while Du jiang yan is considered to be the oldes t functioning watercontrol project in the world. Chengdu ranked third in tourist facilities, management and services among 60 Chinese cities in a customer satisfaction survey released last year. But, Li added that efforts are still needed to develop more tourism products, improve English services and provide accurate translation of traffic signs and scenic billboards. Zhao Yun, chairwoman of British Chamber of Commerce Southwest China, told China Daily that his colleagues found the policy very convenient. A British client once flew here and stayed for just one day to check her ordered goods, she said. Zhao was born in Shanxi province, but she has lived in Chengdu for more than 10 years. My life was like a running race moving from place to place. I also lived in Beijing and Shanghai before, she said. But Chengdu is a place that you never want to leave once settling down. It is now my second hometown, she said. If the environment is further improved, the city will attract more people to visit and live, with the 72hour visafree policy and pelling conditions in transportation, culture, climate and cuisine, he said. Foreigners also gave positive feedback on the policy. A spokesman from Dell Inc said the pany has a global hub of operation in Chengdu, so the threeday visa has an immediate and positive influence on the pany39。s business development. Rudy Buttignol , president of the public broadcasting pany in British Columbia, Canada, said his work requires frequent travel to Chengdu and the policy makes the trips easier. Data from the city39。s public security bureau shows some 100 foreign visitors enjoyed the 72hour policy by the end of March, most of them from the United States, the United Kingdom and Germany. Chengdu also reported robust growth in its overall tourist industry last year. Official statistics show that it received some 150 million tourists last year, an increase of 28 percent from 2021. Around million came from abroad, an increase of 12 percent. Total revenue from tourism surpassed 133 billion yuan ($). During his visit to Kazakhstan in September, Chinese President Xi Jinping proposed that China and Central Asia join hands to build a Silk Road economic belt to boost cooperation. The idea has been w idely echoed in Central Asian countries, being an encouraging blueprint for Chinese areas along the Silk Road that has linked Asia and Europe for more than 2,000 years.

Shaanxi the start of the ancient Silk Road has positioned itself as the new starting point for the development of the Silk Road Economic Belt, w hich will strengthen China39。s cooperation with Central Asian countries, a senior official said.
