（3）句中的have to 表示“必須，不得不”。
<1>have to 后面接動(dòng)詞原形，當(dāng)主語(yǔ)為第三人稱單數(shù)時(shí)，用has to 。例如：
my home is far from my school, so i have to get up early every morning.
我家離學(xué)校很遠(yuǎn)，所以我不得不早晨早起。
tom has to stay at home to look after his sister.
湯姆不得不呆在家里照顧他的妹妹。
<2>have to 用于否定句和疑問(wèn)句時(shí)，要根據(jù)時(shí)態(tài)加助動(dòng)詞。例如：
he doesn’t have to do his homework at school.
他不必在學(xué)校里做作業(yè)。
we won’t have to go to school tomorrow.
我們明天不必去上學(xué)了。
does she have to finish all the work today?
她今天一定要把全部工作做完嗎？
<3>辨析：have to 與must
在表示“必須”這個(gè)含義時(shí)，have to 和must很接近，只是must較強(qiáng)調(diào)主觀看法，have to 較強(qiáng)調(diào)客觀需要。如果是用于指現(xiàn)在，兩者很多時(shí)候是可以替換的。不過(guò)，have to 應(yīng)用的更為廣泛，尤其是在口語(yǔ)中。另外，have to 可用于多種時(shí)態(tài)，而must只能用于一般現(xiàn)在時(shí)。例如：
i have to go home early this afternoon.
我今天下午得早回家。（強(qiáng)調(diào)客觀原因）
we must clean our classroom every day.
我們必須每天打掃教室。（強(qiáng)調(diào)主觀看法）
he will have to finish the work before 10:00 today.
他今天10點(diǎn)前必須做完這項(xiàng)工作。
my brother had to work last night.
我弟弟昨天晚上不得不去上班。

例如：
1. the bus is coming across the bridge.
2. they often go to school across the street.
3. can you swim across the river ?
“through”，意為“從中間穿過(guò)”。例如：
1. the deer is going through the forest.
