1. 在 if 和 unless 条件句中,我们经常在从句中使用时态。
2. 当 if 条件从句位于句首,需要在 if 条件从句后加上(标点符号)。
3. 有时,我们可以用代替 unless。

1. 一般现在
2. 逗号
3. if...not

1. 在if和unless引导的条件句中，从句通常使用一般现在时来表示将来的情况，这是条件句的一个基本规则。
2. 当if条件从句位于句首时，为了语法的正确性和句子的连贯性，通常需要在从句后加上逗号。
3. unless的意思是“除非”，有时我们可以用if...not来代替unless，表达相同的含义。

1. Snakes will only a you if you disturb them.
2. The m is usually bigger and more brightly coloured than the female.
3. A new (中巴) runs to the beach.
4. The Pixar movie s would go on to create movies like Toy Story and Finding Nemo.
5. A p bear has stolen my sleeping bag.

1. attack 2. male 3. minibus 4. studio 5. polar

1. 根据音标、首字母"a"及语境“蛇只有在你打扰它们时才会攻击你”，填attack。
2. 由"bigger and more brightly coloured than the female"及首字母"m"，填male。
3. “中巴”对应的英文是minibus。
4. 结合"create movies like Toy Story"及首字母"s"，指皮克斯电影工作室，填studio。
5. "p______ bear"结合常识，填polar（北极熊）。

二、用所给单词的适当形式填空
1. Julie says she won't go to the party unless she .
2. If the government attention to the safety of food, our health will be in danger sooner or later.
3. If you don't get enough sleep, you sleepy in class.
4. She doesn't know if he the game. If he ______ (win), she'll marry him.
5. If I have a chance to go abroad for further study, I it.

1. is invited
2. doesn't pay
3. will feel
4. will win; wins
5. will take

1. 本题涉及unless引导的条件状语从句，遵循“主将从现”原则，即主句用一般将来时，从句用一般现在时。且she与invite之间是被动关系，所以用一般现在时的被动语态，故填is invited。
2. 本题是if引导的条件状语从句，遵循“主将从现”原则，主句用一般将来时，从句用一般现在时。the government是第三人称单数，否定形式借助助动词doesn't，后面动词用原形，故填doesn't pay。
3. 本题是if引导的条件状语从句，遵循“主将从现”原则，主句用一般将来时，从句用一般现在时，故填will feel。
4. 第一个空，她不知道他是否会赢得比赛，用一般将来时will win；第二个空，if引导的条件状语从句，遵循“主将从现”原则，主句用一般将来时，从句用一般现在时，he是第三人称单数，win用第三人称单数形式wins。
5. 本题是if引导的条件状语从句，遵循“主将从现”原则，主句用一般将来时，从句用一般现在时，故填will take。

三、短文填空：阅读下面短文,在空白处填入一个适当的单词或用括号内单词的正确形式填空
Say the words "reality TV" and the show that comes into most people's minds is Big Brother. Love it or hate it, there have been versions (版本) in more than seventy countries! The basic format is simple: put a group of (1) (strange) into a house, record everything they do and watch how they manage (2) (live) together.
Actually, the idea wasn't original. A similar show, The Real World, was broadcast in 1992 on MTV. But the format really became popular with the (3) (succeed) of Big Brother, and it has been copied again and again, including celebrity versions.
So (4) makes these shows so attractive? Actually, (5) (live) with strangers is stressful and also personality problems are common. Contestants often have to share tasks and housework and this also (6) (bring) conflict (冲突). "It's all about relationships," says TV critic (批评家) Jo Barnett. "Some characters are (7) (please), and some are not, but they are all real people."
But is (8) healthy to be so interested in other people's private lives? And what kind of people want to appear in front of TV (9) (camera) for twenty-four hours a day? Not everyone was in favour of such shows, including the first ever (10) (win) of Big Brother, Bart Spring. "I'm not a fan of the programme or of people becoming famous for being stupid." he says.

1. strangers
2. to live
3. success
4. what
5. living
6. brings
7. pleasant
8. it
9. cameras
10. winner

1. 考查名词复数。a group of后接可数名词复数，strange的名词形式是stranger，所以填strangers。
2. 考查固定搭配。manage to do sth.是固定用法，意为“设法做成某事”，所以填to live。
3. 考查名词。the后接名词，succeed的名词形式是success，the success of表示“……的成功”，所以填success。
4. 考查特殊疑问词。根据语境，这里问是什么让这些节目如此有吸引力，用what表示“什么”，所以填what。
5. 考查动名词。这里作主语，动词不能直接作主语，要用动名词形式，live的动名词是living，所以填living。
6. 考查主谓一致。主语this是单数，句子是一般现在时，谓语动词要用第三人称单数形式，bring的第三人称单数是brings，所以填brings。
7. 考查形容词。根据语境，有些角色令人愉快，有些则不然，please的形容词形式pleasant表示“令人愉快的”，所以填pleasant。
8. 考查形式主语。it作形式主语，真正的主语是后面的不定式短语，所以填it。
9. 考查名词复数。camera是可数名词，这里表示“电视摄像机”，要用复数形式cameras，所以填cameras。
10. 考查名词。the后接名词，win的名词形式是winner，表示“获胜者”，所以填winner。
