告诉你一个窍门，是从我妈妈那里学来的。
Here’s a tip I picked up from my mother.
While
1) While 作连词，有两种含义：作“当……时候”
解时，引导时间状语从句，且从句中的谓语动词
常用延续性动词或状态动词；作“而，然而”
解时，表前后意义上的对比。
Millie came in while we were talking.
我们正聊天的时候，米莉进来了。
Some people waste food while others haven’t enough.
有人浪费食物，而有人却食不果腹。
2）while 作名词，一段时间，一会儿
Can you wait a while or do you have to leave right now
你能不能等一会儿，还是现在就必须离开？
With no light outside，it felt like midnight.外面没有光亮，感觉就像半夜一样。
“with no light outside”是“with＋宾语＋宾语补足语”结构做伴随状语。outside是副词，作with no light的补足语。补足语常为形容词、副词或介词短语等。
Ben's dad was putting pieces of wood over the windows while his mom was making sure the flashlights and radio were working.本的爸爸正在把一块块木头钉在窗户上面(加固)，同时他的妈妈正在确认手电筒和收音机能正常使用。
make sure意为“确保；确认”，常见用法如下：
make sure of＋名词/代词/动名词，意为“弄明白/确信……”
make sure to do sth.意为“确保做某事”
make sure＋that从句 意为“确保……”
…when the rain began to beat heavily against the windows.当雨点开始重重地打在窗户上的时候……
beat意为“敲打”，在此处作不及物动词，其过去式为beat。
beat还可作及物动词，意为“战胜；打败”，其后接打败的对象。
e.g. Mr.Brown beat Tom for lying.布朗先生因汤姆说谎而揍了他。
e.g. In yesterday's game，we beat them.在昨天的比赛中，我们打败了他们。
【易混辨析】beat与win
beat 意为“打败”，指在游戏或比赛中击败对手，其宾语是比赛或竞争的对手，如球队、人等。
win 意为“获胜；赢；赢得”，指在竞赛或战争中获得胜利，其宾语多为表示比赛、战争、奖品、金钱或奖牌等。
against在此处作介词，意为“碰；撞”。
e.g. Jim stood against the table.吉姆靠着桌子站着。
【拓展延伸】against作介词还可表示“反对；与……方向相反；逆着；与……比赛”。
He finally fell asleep when the wind was dying down at around 3：00 a．m.凌晨三点左右风渐渐平息，他才终于得以入眠。
【易混辨析】asleep，sleepy，sleeping与sleep
asleep 形容词，意为“睡着的”，可作表语或宾语补足语。
sleepy 形容词，意为“困倦的；瞌睡的”，可作表语、定语或宾语补足语。
sleeping 形容词，意为“睡着的”，只作定语，用来表示与睡觉有关的物品，如sleeping bag睡袋，sleeping pill安眠药。
sleep 动词&名词，意为“睡觉”。
die down逐渐变弱；逐渐消失
e.g. We hope that the storm can die down before we go sailing.我们希望暴风雨能在我们出航前平息。
【拓展延伸】与die相关的短语：

【易混辨析】rise与raise

make one's way to意为“前往；费力地前进”。若其后接地点副词，应省略介词to。
e.g. Though it was raining hard，he made his way home.
尽管雨下得很大，他还是回家了。
【拓展延伸】
①make one's way to do sth.意为“费力地做某事”。

②way的常用短语：

all the way自始至终；一直 by the way顺便问一下
I had trouble thinking clearly after that because I was very afraid.之后由于害怕，我连清晰地思考都有困难。
have trouble doing sth.意为“做某事有困难”。“在(做)……方面有困难”的表达有have problems/trouble/difficulty (in) doing sth.；have problems/trouble/difficulty with sth.

他们昨晚写了信给他们的朋友。
(表达了他们已写好的意思，整个写的过程已完成)
