【句式分析】本句是復(fù)合句。ifleftunchecked是條件狀語從句的省略，if后面省略了theyare。

狀語從句的省略（1）可以省略成分的狀語從句：時間、條件、讓步、方式狀語從句等。（2）狀語從句省略成分的條件：從句主語與主句主語一致，或從句主語是it；從句謂語含有be，包括系動詞be、進(jìn)行時態(tài)的be或被動語態(tài)的be。（3）常見的連詞有：when，while，once，before，till/until，whenever；if，unless；though/although；as，asif等。

單元復(fù)雜句式研析狀語從句省略成分后的常見類型：連詞+現(xiàn)在分詞/過去分詞/介詞短語/形容詞。Ifinvolvedinthiscase，youwillbepunished.If（youare）involvedinthiscase，youwillbepunished.If
