)ALIENS ARRIVE
Tina woke up at midnight. She looked out of her window and saw a yellow light in the sky. It suddenly dived towards the ground. She heard a noise and saw a red light.
The next morning, Tina mentioned it to her brother Tom. “I’m sure something landed in the forest near the hills as I heard a loud noise last night.” she said. “Let’s explore after school.”
At 6 p.m., Tina and Tom reached the forest. They heard some voices speaking a strange language, so they hid behind some bushes and kept quiet. Then they saw an alien! It was tall, with a round head and a silver body. It was standing next to a long spaceship. The spaceship was damaged because of a crash.
The children were frightened. Suddenly, another alien appeared from the bushes in front of them. It discovered them and made a terrible noise. The children ran away in fear.
The next morning, Tina and Tom told their parents about the strange creatures.
“They were very ugly. They had some hair, but they didn’t have any feathers,” said Tina.
“There was something written on the spaceship,” said Tom. “It looked like this. I wonder what it means.” He drew some lines on a piece of paper.
But Dad said, “Since no one else saw these aliens, I refuse to believe you. Now go to school!”
The children spread their wings and flew to school together. Dad looked at the piece of paper with the strange marks on it. “It looks strange,” he said, as he looked at the word “EARTH”.

原因状语从句
1 because, since 和 as 的区别
（1）because：语气最强，表示直接原因，可用于回答 why 提出的问题、引导表语从句、用于强调句等，而其余三者均不行：
“Why didn’t he come ” “Because he was ill.” “他为什么没来 ”“因为他病了。”
We must stay at home because it rained. 我们必须呆在家，因为下雨了。
（2）since 较弱，指双方都明确的原因或众所周知的原因，泽为“既然”，侧重主句，从句表示显然的或已知的理由。
Since you don't like it, I'll put it away. 既然你不喜欢，我就把它放在一边。
Since everybody is here, let’s begin our class. 既然每个人都在，我们开始上课吧。
（3）as “由于，鉴于”，指客观事实，语气比since 弱，略口语化，常与since互换使用。
As there was no answer, I wrote again.
鉴于没回复，我又写了一封信。
语气 位置 意义
because 最强 前或后 “因为”，表示客观因果关系
since 较强 前 “既然”，把众人所知的事实当作理由，较为正式
as 较弱 前 “由于”，把众人所知的事实当作理由，口语化
总结：
2、because习惯上不与so连用
　　汉语习惯上说“因为…所以…”，但英语习惯上却不能将 so与because 连用：
　　正：Because it was raining, we stayed at home. / It was raining, so we stayed at home.
　　误：Because it was raining, so we stayed at home. 因为下雨，所以我们呆在家里。
3、because VS because of
because 后加句子，引导____________。
例如： I do it because I like it. 我做这件事情因为我喜欢。
because of 后加__________、__________和____________。
The football match will be put off because of the bad weather.
因为坏天气，足球赛将会延期。
两者可以互换
He can't come because he is ill.
==He can't come because of ________ _________. 他因病不能来。
I said nothing about it because his wife was there.
== I said nothing about it because of his wife's being there
因为他妻子在那儿，我对此事只字未提。

原因状语从句
1 because, since 和 as 的区别
（1）because：语气最强，表示直接原因，可用于回答 why 提出的问题、引导表语从句、用于强调句等，而其余三者均不行：
“Why didn’t he come ” “Because he was ill.” “他为什么没来 ”“因为他病了。”
We must stay at home because it rained. 我们必须呆在家，因为下雨了。
（2）since 较弱，指双方都明确的原因或众所周知的原因，泽为“既然”，侧重主句，从句表示显然的或已知的理由。
Since you don't like it, I'll put it away. 既然你不喜欢，我就把它放在一边。
Since everybody is here, let’s begin our class. 既然每个人都在，我们开始上课吧。
（3）as “由于，鉴于”，指客观事实，语气比since 弱，略口语化，常与since互换使用。
As there was no answer, I wrote again.
鉴于没回复，我又写了一封信。
语气 位置 意义
because 最强 前或后 “因为”，表示客观因果关系
since 较强 前 “既然”，把众人所知的事实当作理由，较为正式
as 较弱 前 “由于”，把众人所知的事实当作理由，口语化
总结：
2、because习惯上不与so连用
　　汉语习惯上说“因为…所以…”，但英语习惯上却不能将 so与because 连用：
　　正：Because it was raining, we stayed at home. / It was raining, so we stayed at home.
　　误：Because it was raining, so we stayed at home. 因为下雨，所以我们呆在家里。
3、because VS because of
because 后加句子，引导____________。
例如： I do it because I like it. 我做这件事情因为我喜欢。
because of 后加__________、__________和____________。
The football match will be put off because of the bad weather.
因为坏天气，足球赛将会延期。
两者可以互换
He can't come because he is ill.
==He can't come because of ________ _________. 他因病不能来。
I said nothing about it because his wife was there.
== I said nothing about it because of his wife's being there
因为他妻子在那儿，我对此事只字未提。
