Chris, 可以請你講解一下嗎? 謝謝你喔^^
(C)1. With so many confusing questions, why not _____ the easier ones?
(A)add to (B)take over (C)start with (D)fill up (A)可以選嗎?
The phrase “with so many confusing questions” refers that the speaker has “many questions” that he or she does not know, so the speaker, of course, suggests starting from the easier ones of these questions. Therefore, you cannot add other questions to the ones already exist.
(D)2. I can’t find my keys. I must _____ them at home.
(A)leave (B)have leave (C)be left (D)have left (A)可以選嗎?
Remember what you have learned in the summer English class. If you are talking or guessing something happening in the past, then you use “must have + pp.” By contrast, if you have a strong guess about something happening at present and in the future, then you use “must root-verb.”
(B)3. Tim doesn’t want to live an ______ life. He is always looking for excitement.
(A)common (B)ordinary (C)scientist (D)universal (A)可以選嗎?
The meaning is correct. However, see the precedent article “an” so you can only choose the word that starts with a vowel sound.
(B)4. In the past, the leaves of sweet potatoes were fed _______ pigs; but now people like to eat them.
(A)at (B)to (C)by (D)on (D)可以選嗎?
People feed pigs on/with sweet potatoes. 人們以蕃薯餵豬。
Sweet potatoes (食物) was fed to pigs (針對豬，給豬的).
(A)5. Our teammates didn’t put the blame on Jack, ________ on me.
(A)but (B)instead (C)instead of (D)rather (B)可以選嗎?
The word “instead,” an adverb, is usually put in the beginning or the last of the sentence used to modify the whole sentence. In this sentence, we can tell there are two events: Our teammates did not blame Jack, but they blamed me. So, if you put “instead,” you should put a conjunction or a semicolon.
Chris, 我知道這一題你上課有講解過,但可不可以再請你再講解一次, 謝謝!
