教学内容

作业完成情况： 优□ 良□ 中□ 差□
Step 2 Grammar ——条件状语从句
引导条件状语从句的连接词主要有：if（如果）、unless（除非）和as?long?as（只要）等。
1. 引导条件状语从句最常用的连词是if，意思为“如果、假如”。
1. 1 由if引导的条件状语从句表示在某种条件下某事很可能发生。
【例句】If it rains tomorrow, I will stay at home. 如果明天下雨，我会待在家里。
If you ask him, he will help you. 如果你请他帮忙，他会帮你的。
【考点】当主句为将来时态或含有将来意义时，条件状语从句习惯上要用一般现在时表示将来，而不能直接使用将来时态。
387096017145387096017145【注意】误：I don’t know if it will rain tomorrow. If it will rain tomorrow, I will stay at home.
正：I don’t know if it will rain tomorrow. If it rains tomorrow, I will stay at home.
句中的第一个 if 引导的是宾语从句（if意思为“是否”），从句谓语用一般将来时表示将来；第二个if引导的是条件状语从句（if意思为“如果”），从句谓语要用一般现在时表示将来。
1. 2 当主句表示常规性、真理性的结果时，主句用一般现在时，从句也用一般现在时。
【例句】If you cool the water, it turns into ice. 如果把水冷却就会变成冰。
Water turns into steam if you boil it. 如果把水煮沸就会变成水蒸汽。
1. 3 if从句还可以表示不可实现或根本不可能存在的条件，也就是一种虚拟的条件或假设。
【例句】If?I?were?you,?I?would?go with him. 如果我是你，我会和他一起去。
If there were no air, we couldn’t live. 如果没有空气，我们就不能生活。
2. unless也可以引导条件状语从句，意为“除非， 如果不”。
【例句】You will fail unless you study harder. (= You will fail if you don’t study harder.)
Let’s go out for a walk unless you are too tired. (= If you are not too tired, let’s go out for a walk.)
【注意】unless与if的联系与区别：unless = if… not，通常可以翻译为“如果不，如果没有”；但是unless不能引导否定的条件状语从句，if没有此种限制。
3. as long as (=so long as) 表示充分必要条件，引导语气强烈的条件状语从句，意为“只要”。
【例句】As long as?I?have?time, I?will?come?to?see?you.? 只要我有时间，我就会去看你。
You may borrow my book as long as you keep it clean. 只要你保持书的清洁，你就可以把我的书借去。
【注意】as/so long as 还可以表示“和……一样长”，as long as可用于肯定句和否定句，而so long as只能用于否定句。
【例句】The red pen is as long as the green one.
The red pen isn’t as/so long as the green one.

Hundreds of years ago, a Roman army wanted to capture Scotland. It was difficult for the Scots to drive the Romans away because there were too many Romans. It seemed that the Romans would win.
One night, the captain of the Scots took his soldiers to the top of a hill. “We will rest here tonight,” he said. “Tomorrow we must win, or we will die.”
The soldiers were all very tired, so they fell asleep soon. There were four soldiers on duty (执勤), but they were so tired that they fell asleep one by one. The Romans came together at the foot of the hill secretly. Slowly they climbed up the hillside quietly. Closer and closer they came to the sleeping Scots. They were almost at the top. Suddenly, one of them stepped on a thistle (踩到蓟）.He cried out and woke the Scots soldiers up. In a moment, the Scots soldiers were on their feet and ready for the battle. The fighting was hard and the Scots wiped out (歼灭） the Romans and won at last.
The thistle is not a beautiful plant. It has sharp needles (尖锐的针状物）all over it. Few people like it, but the people of Scotland liked it so much that they made it their national flower.

I knocked into a stranger when he was walking by. “Oh, excuse me, please,” I said. “Please excuse me too. I wasn’t watching where I was going,” he answered. Then we smiled at each other. Both of us were polite to each other. We said goodbye and went on our own way. When I got home later that day, supper was ready and my mother was waiting for me. But it was rice and chicken again. “Don’t make chicken anymore. I don’t like it.” After saying these words, I went into my room.
When I sat at my desk, I thought what happened on my way home. I said to myself,“You can be polite to a stranger, but how can you be so rude (粗鲁的）to your mother?”At this time, I felt very sorry and tears began to run down my face. I quickly went to my mother and said sorry to her. She wasn’t angry with me, but my face turned red.

Every year, thousands of students decide to study in another country for a month, a term, or a year. Studying in another country can be an exciting experience.

Once you are there
After the first few weeks in another country, many students may feel homesick. They miss their family and friends. And they also miss the way they used to do things. Remember that it takes time to get used to a new place, school and the culture. When you feel sad or miss your family and friends, try to talk to others, or write about your feelings in a notebook.

Imagine you are living in a moving house. Inside the house, there is a small kitchen, a bathroom and a bedroom. Everything you need is close at hand.
In the US, you can really see these moving houses. They are called recreational vehicles (RV,房车). People call them houses on wheels. When it’s holiday time, the whole family often get into this lovely house and go for a trip across the country.
Compared to a real house, this house on the road is smaller for a family who have to spend the whole day together. But the best thing about it is that it changes your journey into a free exploration (探索).
You can drive as long as you like without worrying about finding hotels. Or you can just stop somewhere nice and stay for a few weeks. You may also meet other families who are on road trips. Together, you take out your snacks. It's camping time with a lot of talk and fun.
Of course, RVs are not always convenient. They can sometimes break down and you have to spend time mending (修理）them. But this kind of road trip still wins people’s hearts because they can go whenever and wherever they want.
( )41. What do people use their RVs for?
A.For their work. B.For their holidays. C. For their families. D.For their study.
( )42. In the US, people call RVs moving .
A.cars B.wheels C. houses D.buses
( )43. What is the advantage (优势）of the RV?
A.It is big enough to hold all your family members.
B.It is cheaper and more comfortable than a house.
C.It can make your trip free enough.
D.It can change your journey into a happier one.
( )44. What can we know from the passage?
A.There is everything you want in the moving house.
B.RV is popular in the US.
C.RV is always convenient for a trip.
D.RV is too expensive and few people can buy it.
( )45. What does the passage mainly talk about?
A.A kind of cars — RVs. B.The advantages of RVs.
