As it turned out, their analysis was accurate in data.
结果证明,他们的分析在数据方面是很准确的。
To be accurate, there are 46 institutes located along the main road of the city.
准确地说,该市沿着这条主要道路共有46所研究所。
make it...(for sb.) to do...
【句式分析】
在make it...(for sb.) to do...结构中,it是形式宾语,to do...是真正的宾语。常用这种结构的动词还有find, feel, think, consider等。
真正的宾语有三种形式,动词不定式短语,-ing短语或从句。用-ing作真正的宾语时,宾补通常是no use,no good等。当真正的宾语是动词不定式短语时,不定式短语可以有自己的逻辑主语,该逻辑主语由介词for引出。
make it...(for sb.) to do...

②He considered it of great importance ________ (put)aside some money every month, for the age.
③He likes to stay up late, so he often feels sleepy, ________ makes it difficult for him to concentrate on what he is doing.

In today's digital age, (secure) is critical our lives. We should advocate (do) regular checks to ensure our systems are safe.
(persuade) plays a vital role in convincing others of its importance. A (persuade) argument can make people switch security measures (automatic). Those who have a good command
technology can integrate it other systems for better protection. However, there are (oppose) views on sharing personal data for security. While (available) of advanced security features is important, we must consider risks and have potential (deal) with them. If proper precautions are (absence), we will be at distance from true security. The right (combine) of measures is needed.
