4.what 考查宾语从句。分析句子结构可知,空处引导宾语从句,从句作介词along的宾语,且空处在宾语从句中作主语,故填what。
5.exploration 考查名词。空处与trade并列,故应填名词exploration,意为"探索"。
6.withdrew 考查时态。由after 1433和 remained可知,此处表示发生在过去的事情,故应用一般过去时,故填withdrew。
7.To reach 考查不定式。此处表示具体的动作,含有将来意味,故应用动词不定式作主语,填To reach。
8.strengthen 考查动词。分析句子结构可知,空处与encourage并列,故填动词strengthen。
9.has invested 考查时态和主谓一致。根据句中的时间状语In recent years可知此处用现在完成时;因主语是China,故谓语动词应用单数形式,故填has invested。
10.in 考查介词。 "With the latest technology 10. hand"是with复合结构,此处介词短语in hand意为"在手头,可供使用",作宾语补足语。
