摘要： 英语词汇丰富,表意准确、细腻,适用范围具体、针对性强。比如,用英语表示"在……之中",我们就要考虑表述对象所处位置、所处范围的个体数量等因素来选用不同的词汇。很多同学对此常常辨析不清,下面我们分三种情况来介绍一下怎样表示"在……之中"。第一种,表述对象所在的范围数量为两者,即"在两者之间",此时用between表示;另外,between常和and连用,构成"between...and..."结构。例如:There is a table between the two trees.

摘要： The objective of this study was to evaluate the relationship of the calving number with productive indicators in Nelore cows in a grazing system in the Bolivian tropics.Retrospective data,corresponding to the period between 1991 and 2019 referred to 1,566 primiparous and multiparous Nelore breed cows were used.A decrease in the total number of animals was observed from the first to the fifth calving,it was also observed that the age of the first calving was similar in all cows without significant differences,showing that longevity is not associated with the age at the first calving.Live weight presented significant differences(p≤0.05),according to the number of calvings;the fourth and fifth calving cows are the heaviest.Weight of calf at birth did not show a relationship with the number of calvings either.However,it does so in the weight of calf at weaning,which increases from the first to the fifth calving with significant differences(p≤0.05).There were significant differences(p≤0.05)for the interval between calvings,decreasing as the calvings progressed.It is concluded that there is a relationship between the number of calving with productive indicators in Nelore cows in a grazing system in the Bolivian tropics,fundamentally those efficiency variables where longevity is important.

摘要： Architecture is an indispensable part of the development of human civilization and the carrier of human civilization.The evolution of architectural style can also reflect the development of a nation.With the continuous development of history,the preservation and development of historic sites has gradually become a topic of common concern in China and the west.However,with the continuous development of modern technology,there are fewer and fewer traditional cultural elements in the newly-built buildings,which lead to the gradual loss of some traditional architectural culture.In order to avoid the further aggravation of this phenomenon,something should be done.From the perspective of the development characteristics of Chinese and western architectural culture,the characteristics and differences of the development process of Chinese and western architecture were listed from ancient to modern times,and gradually the main reasons for the different development directions and characteristics were analyzed.In addition,according to the law and characteristics of the development of Chinese and western architecture,some methods on how to solve the inheritance of Chinese modern architecture to traditional culture were put forward.

摘要： At the first Belt and Road Forum for International Cooperation in May 2017, Chinese President Xi Jinping stated,“The pursuit of the Belt and Road Initiative is not meant to reinvent the wheel. Rather, it aims to complement the development strategies of countries involved by leveraging their comparative strengths.”1 China and African countries further agreed at the Beijing Summit of the Forum on China-Africa Cooperation (FOCAC) in September 2018 to “form a strong synergy between the Belt and Road Initiative and the 2030 Agenda for Sustainable Development of the United Nations, Agenda 2063 of the African Union (AU), as well as the development strategies of African countries,” which will “lend new impetus to the win-win cooperation and common development between China and Africa.”2 Synergizing their respective development plans and making joint efforts on the Belt and Road construction has become the strategic choice for China and African states to enhance their relations in the new era. It thus calls for our accurate grasp of Africa’s development trends and respect for African countries’ desire for endogenous development, while integrating the Belt and Road Initiative into the process of independent African development.

摘要： The reform and opening-up is a great change in contemporary Chinese society.It not only brought about tremendous changes to China,but also profoundly changed the relations between China and the world.In the diplomatic field since the reform and opening-up,guided by the ideological line of“liberating the mind and seeking truth from facts,”China has adhered to scientific judgment of the international situation and the external environment,keeping in mind both internal and international imperatives,and has broken new ground amid reform and innovation.As China becomes more integrated with the world in a comprehensive and in-depth way,China has significantly changed its diplomatic concepts,policies,patterns and styles.At the same time,China retains the stability and continuity of its overall strategy.China’s international positioning,which has always been a critical premise for the formulation of China’s diplomatic strategy,plays an important role in this duality.“
