“Fashion first of all is culture,” Raffaela Godi, from the audience, told Xinhua. “This fashion show we just saw is an example of     3     is culture, art and fashion together.”

The Miao ethnic group residing     4     (large) in southwest China’s Guizhou Province has a population of 4.3 million and more than 100     5     (branch).

Hikers at the Great Wall who come across Zhou Wenjun consider themselves lucky    1    him admirable. The 44-year-old is more than a security guard; he is a walking library on the manmade fortifications (防御工事).

Zhou replaces his knowledge of history every day so that he can field questions from visitors full of    2    (curious). Zhou's appreciation of the Great Wall    3    (inspire) by a surprising demand on the job years ago. The Simatai section is the only ancient architecture in China that preserves the original form of the Ming Dynasty fortifications. Ever since he took the job in 2018, he    4    (witness) increasing footfall of intensely curious tourists. “Visitors are no longer satisfied    5    what they see; they wonder about the history and culture of the place.

Zhou has a range of official responsibilities including    7    (keep) visitors safe and protecting the Great Wall. He has to climb the Great Wall on    8    daily basis and walks back and forth the entire 5.7 kilometer stretch,    9    he must ensure no one wanders into the undeveloped sections of Simatai.

Mountains are important sources of water supply to humans. Among the ecosystem services     1     (provide) by mountains, water supply is     2     most important because of the large quantity of free-flowing water. Mountain water resources are affected by glacier melt, snowmelt run-off or rainfall run-off.

Sustainable (可持续的) use of mountain water resources is important for both humans and global mountain biodiversity in the economic and     3     (society) context of human progress. Particular attention should be given in the water resources     4     (come) from the mountain areas. Sustainability has been     5     (previous) used as a term to describe a concern related to preservation of natural resources for future. The relation between human development and the need     6     (manage) resources forms a principle to design a dialogue regarding environmental needs. So far, a limited number of studies     7     (publish) on mountain water uses and sustainability. Most studies are focused     8     examining prevention, diversions, and mountain water storage during floods or droughts.

However, insights into water use, as well as employing state-of-the-art technologies, are very important from both a technological standpoint and as elements of practical sustainable     9     (solution) . The interplay between academics, policy makers, and decision makers is important in expanding the scientific knowledge of mountain regions and the ways in     10     water resources could be used in a more sustainable way.

Bacteriophages (phages) and other mobile genetic elements (MGEs) exert an immense selective pressure on     1    (bacterium), which in response have developed a broad arsenal of defence mechanisms.     2     these, CRISPR–Cas (clustered regularly interspaced short palindromic repeats–CRISPR-associated proteins) is a group of widespread RNA-guided adaptive immune systems that are classified into two broad classes, six types and numerous subtypes according to their genetic composition and interference mechanism1. The CRISPR–Cas immune response starts with the    3    (acquire) of short DNA fragments (protospacers) from invading MGEs. The protospacers are inserted as spacers between repeats in the CRISPR array to create a memory of the infection. Next, the CRISPR array is expressed    4     a long transcript that is processed into small, mature CRISPR RNAs (crRNAs), each    5    (carry) a spacer sequence flanked by part of the repeat. Finally, the interference complexes, composed     6     a crRNA and one (class 2) or more (class 1) Cas proteins, degrade the complementary nucleic-acid targets that are often found next to a short protospacer-adjacent motif (PAM). The specificity and programmability of the CRISPR–Cas machinery     7    (lead) to the development of various biotechnological applications in genome editing, molecular diagnostics and more.

In the evolutionary arms race with CRISPR–Cas, phages and other MGEs have evolved diverse strategies to block or circumvent immunity. One widespread evasion mechanism uses protein-    8    (base) CRISPR–Cas inhibitors called anti-CRISPRs (Acrs). So far, more than 100 Acr protein families have been identified    9     inhibit different stages of the CRISPR–Cas immune response, mainly by interacting directly with Cas proteins. For example, Acrs prevent crRNA loading, effector-complex formation, and target DNA binding and cleavage. Notably, the discovery of these natural ‘off switches’ has presented new opportunities    10    (control) the activity of CRISPR–Cas technologies.

On Tuesday, Baidu, a Chinese search engine and artificial intelligence firm, released a new version of its artificial intelligence model, Ernie 4. 0.
