語法要點(diǎn)

A woman who can smell Parkinson’s disease on people has worked with scientists to create the first test that can tell if someone has it.

who從句為定語從句，修飾woman；that從句為定語從句修飾test，這個(gè)從句中if從句為tell的賓語從句。

Joy Milne, from Perthin Scotland, has a rare condition which gives her a very strong sense of smell.

which從句是定語從句，修飾condition。

She thought her husband smelt different when he was 31 years old, but she only realised it was the disease she could smell after he was diagnosed with it at 44, and they met other people with it who smelt the same.

she could smell為定語從句（省略了關(guān)系詞which/that），修飾disease；who從句為定語從句，修飾people。

was diagnosed，被診斷為，謂語被動(dòng)語態(tài)（be done）。

After Milne told a scientist that she could smell Parkinson’s they thought that the smell was caused by a chemical change in skin oil, called sebum, triggered by Parkinson’s.

兩個(gè)that從句不是定語從句，而是tell和think的賓語從句。

triggered by Parkinson’s過去分詞短語做skin oil的定語。（過去分詞有被動(dòng)關(guān)系）

They collected sebum from people with Parkinson’s and compared it with sebum from healthy people, finding different chemicals in the two groups.

finding部分為現(xiàn)在分詞短語，做結(jié)果狀語。（現(xiàn)在分詞有主動(dòng)關(guān)系）

The test scientists have developed is 95% accurate in a laboratory and takes just three minutes. It analyses sebum, wiped from the back of the neck, by weighing the molecules (the building blocks of a substance) in it.

have developed謂語現(xiàn)在完成時(shí)態(tài)（have done）。

wiped部分為過去分詞短語，做sebum的定語。

It is hoped the NHS will soon be able to use the test to spot and begin treatment of Parkinson’s disease more quickly.

（that）the…部分不是賓語從句，而是主語從句，形式主語it指代它。

She often avoids places with lots of smells, but she is now working with scientists to see if she can smell other things, like cancer.

if從句為賓語從句
