Notes

[1] What you've just read is information that you will keep in short term memory until you decide if it is worth keeping for a longer time.

本句中，What you've just read是一個主語從句，that you will keep in short term memory until you decide if it is worth keeping for a longer time是一個定語從句，修飾和限定表語information。在該定語從句中，until you decide if it is worth keeping for a longer time是時間狀語從句，修飾謂語will keep。在該時間狀語從句中，從句if it is worth keeping for a longer time作decide的賓語。

[2] Not everything is stored online, and, even if it is stored online, there is no guarantee that the information that you saw today will still be there next week, and there is no guarantee that the material

will be organized in a logical manner that will facilitate your finding it again.

本句中，Not everything is stored online是一個部分否定的句子，意思是“并非所有的東西都在線存儲”。even if引導了一個讓步狀語從句，意思是“即使”。that you saw today是定語從句，修飾和限定the information。that will facilitate your finding it again也是定語從句，修飾和限定a logical manner。

[3] The problem for most researchers is not that the information doesn't exist in a library or in a journal or in a magazine or in a motion picture, but that they have yet to discover the organizing principles that are designed to help them find the information they need.

本句中，The problem for most researchers是主語，is后面的部分是表語。not that…but that的意思是“并非……而是……”that are designed to help them find the information they need是定語從句，修飾和限定the organizing principles。在該定語從句中，they need是定語從句，修飾和限定它前面的the information。

[4] People, experts in their fields, have taken the time and trouble to organize access to all the stored information that they can get their hands on in order to make it searchable and accessible to other people.

本句中，that they can get their hands on是定語從句，修飾和限定all the stored information。in order to make it searchable and accessible to other people作目的狀語，it指all the stored information。take the time and trouble to do sth.的意思是“花費時間和精力去做某事”。
