1：help with housework 幫助做家務
help v. 幫助 eg. Thanks for your advice, Mr. Clark. That helped me a lot last term.
n. 幫助 eg. I can’t make it without your help.
相關詞組：
help sb.(to) do sth. 幫助某人做某事
eg. Could you please help me to take care of my puppy when I am away?
help sb with sth. 幫助某人（做）某事
eg. Tom is a good boy. He often helps his mom with housework.

A.with, for B. learning, with C. with, to D. learn, with
【答案】C.
【解析】根據搭配help ..with, help ..do..., help ...to do...，去掉A，B, D 選項。
2：health n. 健康
eg. Nowadays, young people don’t have time to take care of their health. They are too busy.
be in good health=keep in good health=stay in good health 保持健康
Linda wants to keep in good health so she ______ twice a week.
A.eats junk food B. hang out C. go on a vacation D. plays tennis
【答案】D
【解析】首先單數第三人稱剩下A，D。既然是keep in good health（保持健康），所以plays tennis是符合的。而eat junk food （吃垃圾食品）是不合題意的。
3：mind n. 頭腦，心智
eg. Playing chess is good for your mind and body.
mind v. 介意
常用在句型would you mind sth./ doing sth? 你介意（做）某事嗎？
Would you mind moving your bike?
Would you mind not _______ ? There are some children here.
A. smoking B. smoke C. to smoke D. Smokeing
【答案】A。
【解析】本題考查mind 的用法。介意做某事，mind doing sth. 介意不做某事 mind not doing sth.
另外，動詞smoke的現在分詞是smoking。
4：although conj. 雖然，儘管，即使
eg. Although my grandma is 85-year-old, she is still in good health .
注意：在英語中，although和 but（但是） 不能連用。一個句子中只能用although 或者but。
______ my grandma is 85-year-old, _____ she is still in good health .
A. Although, / B. Although, but C. /, although D. But, /
【答案】A。
【解析】通過分析句意知道，兩個分句是轉折關係。前面用although或者中間用but。
5：full adj. 滿的；充滿的
常用短語為be full of...， 充滿...,滿是；反義詞是empty，意為「空的」。
eg. The supermarket is full of people now. Christmas is coming.
The bottle was full ______ milk. Little Tom just drank it up.
A. with B. in C. of D. at
【答案】C
【解析】本題考查full的用法。be full of意為「充滿……」，故用介詞of。
full adj. 吃飽的；過飽的，反義詞是hungry，飢餓的。
eg. ---- Are you hungry？
Nope. I just had a burger with Lisa.
6：She says it's good for my health. 她說它對我的健康有益。
1.本句是一個賓語從句。
She says 是主句，其後省略了that，it's good for my health是從句。
Eg. Tom says that he wants to be a movie star.
其中be good for 對……有益
eg. Exercise is good for your health.
含有good的常見詞組 還有
① be good at 在……方面做得好；擅長……
Eg.He is good at learning languages.
②be good with 與……相處融洽
eg. Teachers should be good with their student.
7：I go to the movies maybe once a month.我可能一月去看電影一次。
其中maybe adv. 大概；或許；可能
maybe
副詞，意為「或許；大概」，表推測。

may be
由情態動詞may和 be構成，意為「可能是」，在句中作謂語。
Your dad may be right this time.
這次可能你爸爸是對的。
______ Lin Tao wants to be a basketball player like Yaoming.
A. May be B. May C. Also D. Maybe
【答案】D.
【解析】本句已經有謂語wants to be， 所以答案是 Maybe 可能是，表推測。

least 是little的最高級,意為 最少的，最小的。
Eg. He has least money of all of us.
Sheworks least.
We have least time.
常見詞組：at least 至少；不少於；起碼，反義短語為：at most 至多
eg. At least he should say thanks to the old man.

A. are like B. such as C. such like D. as such
【答案】B
【解析】他會說3門外語，例如。。。。
10：And remember，「old habits die hard」. 請記住：舊習難除。
die v. 消失；消滅；死亡
①作「死亡」講，是短暫動詞，不能與表示一段時間的狀語連用。
②dead 死的，是die的形容詞形式。可作表語或定語。作表語時，表示狀態，可以與表示一段時間的狀語連用，替代動詞die。
③die可以用於進行時態，表示「即將死去，奄奄一息」。
④death 死亡，是die的名詞形式。
The ______ dog ______ because of illness.
A. dead；death B. died；dead C. died；death D. dead；died
【答案】D。
【解析】dog是名詞，其前用形容詞dead，去掉B、C兩項；第二空內的詞在句中作謂語，故選一個動詞，句意為「這條死了的狗是由於疾病而死的」。
11：一般現在時和頻度副詞
How often do you exercise？
你多久鍛鍊一次？
how often 多久一次，用於對動作發生的頻率進行提問。回答應該是頻度副詞或表示頻率的詞組，如always，usually，often，sometimes，hardly，ever，never，以及every day，once a week，three times a day 等。
Eg. I never eat junk food.
I always get up early.
Sometimes, my mom and I go shopping together.
除了考查意義，還經常考查單數第三人稱的運用與變化。

---Every day.
A. How long B. How often C. How old D. How soon
