Microvessel reduction and microcirculatory disturbance are important factors of the genesis and progression of OP. Diagnostic imaging is of critical importance in identifying individuals at risk for OP and also in monitoring response to treatment. Quantitative dynamic contrast-enhanced MRI (DCE-MRI) is a noninvasive method to evaluate the characteristics of bone marrow microcirculation by gadolinium contrast agents. This paper mainly introduces the basic principles of DCE-MRI and the progress of bone marrow perfusion of OP with DCE-MRI.%骨质疏松(OP)是一种以骨强度降低为特征,导致骨折易发的骨病。

Unit 7 It's raining 重点解析Section A1. —How's the weather? 天气怎么样?—It's raining. 天正在下雨。
How's the weather...?是询句天气情形的句型。
意为“天气怎么样?”其后能够加时刻状语及地址状语来限定何时的天气及哪里的天气。
如:How's the weather today?今天的天气怎么样?How's the weather in Shanghai?上海的天气怎么样?What's the weather like?与How's the weather?意思相同。
它们的回答能够用“It's +动词的此刻分词形式”,也能够用“It's+形容词”。
如:—How is the weather?—It's raining/ rainy.It's raining为此刻进行时,用于陈述即时天气状况,即“正在下雨”。
It's rainy为一样陈述句,rainy指阴雨天气,既可陈述即时天气状况,也可作为一段时期内天气状况的概述。
若是提问者是想了解此刻的天气,回答用It's raining 和It's rainy都能够,但如果是是问一段时刻的天气,只能用It's rainy。
2. It’s sunny. 天气晴朗。
sunny是形容词,意为“晴朗的”,它是由名词sun派生而来的。
英语中名词变成形容词的方式有以下几种:◆在名词后面加-y;如:rain—rainy, cloud—cloudy, wind—windy, snow—snowy, storm—stormy (沙尘暴的), health—healthy, luck—lucky若是名词以重读闭音节结尾,且词尾只有一个辅音字母,这时应双写词尾的辅音字母再加-y。
