Unit12 Don’t eat in class
i will call you as soon as i arrive in beijing.
單詞 get 和reach 也有到達的意思，get 為不及物動詞， 后面跟地點名詞需加介詞to， reach為及物動詞，直接跟地點名詞作賓語，當get 和arrive 后接副詞時，不用介詞。
the train arrives in beijing at 8 o’clock.
=the train gets to beijing at 8 o’clock.
=the train reaches beijing at 8 o’clock..
what time did your father arrive home last night?
③late 在句子中作副詞，也可以作形容詞，其反義詞是early, be late for +名詞表示“……遲到”。
he often comes to school late.
i do my homework until late at night.
don’t be late for school again.
better late than ever.
6.don’t listen to music in the classroom or the hallways.
⑴句中的listen 表示“（注意的）聽， 傾聽”，為不及物動詞，后面加介詞to 接賓語，即：listen to sb. /sth.
do you like listening to classical music?
you should listen to your teacher carefully in class.
注意： listen 與hear
①listen 表示“聽”強調的是動作，hear 強調的是結果，意思為“聽見，聽到”。
i listened carefully but i heard nothing.
can you hear someone singing in the next room?
②listen 可用于祈使句, 但hear不可以.
listen to me carefully.
don’t listen to music in class.
③listen 強調動作過程，故可以用進行時態，hear不可以.
all the students are listening to the teacher carefully.
⑵本句中的or用在否定句中,表示“…或 …都不”，在肯定句中表示“和，都”的and變為否定句時，一般變為or.

---i don’t like rice or meat.

7.can we wear hats in school?
①can 是英語中最常用的情態動詞之一，他本身不表示動作，只是說明“能不能”的意思，表示動作的是他后面的動詞原形, can 沒有人稱和數的變化，其否定形式為can’t.
can you fly a kite? yes, i can.
can we eat in the classroom? no, we can’t.
②wear 作動詞，“穿著，戴著”，表示狀態。
