根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

    It is necessary but difficult for English beginners to memorize new words, and long lists of words seem to make the mission impossible. They are puzzled why they try to memorize words with great efforts but forget them easily. That's why there are often inquiries about how to memorize new words.

____ Here are some tips to help.

    ____ We too often separate the process of new words memorization from pronunciation. In fact these two can be combined and each will enhance the other. Saying the word to ourselves helps activate aural(hearing) memory, which helps the memory. ____ The more familiar we are with the word,

the greater chance we will have to keep it for the rest of our life.

    Never memorize single English words. ____ Relate the word to terms we already know, either as synonym or antonym. For example, the word "gargantuan" is similar in meaning to words "gigantic", ”huge" and "large". Make a sequence of words: "small, medium, large, gigantic, and gargantuan".

    Create a mental image of the word that involves strong emotions. Think, "The gargantuan whale is going to swallow me whole".

    Learning English words requires action. Complaining how difficult it is to memorize new words will be of little help. ____ Have a try with ten words a day and you will see what a difference you will make in our English learning.

A. So take action right now.

B. Speak the word while memorizing it.

C. Memorizing new words is very important.

D. Actually, some have given up learning new words.

E. In fact, learning new words needn't be that difficult.

F. Make as many associations and connections as possible.

G. The sound of word helps us recall the spelling and familiarizes us with the word.
