A. will be B. would have been C. could have been D. would be 答案：D時(shí)間謂語動(dòng)詞的虛擬形式從句主句現(xiàn)在動(dòng)詞過去式（be 多用were）would / should / could / might + 動(dòng)詞原形 過去had + 過去分詞would / should / could / might + have + 過去分詞將來動(dòng)詞過去式或 should / were to + 動(dòng)詞原形would / should / could / might + 動(dòng)詞原形1.The rice _ if you had been more careful.

A. drove ; didnt get B. drove ; wouldnt get C. were driving ; wouldnt get D. had driven ; wouldnt have got答案：CADCD（一）、含蓄條件句 含蓄條件句就是虛擬條件暗含在短語或上下文中，從句不表現(xiàn)出來。這時(shí)，必須根據(jù)句中表述的意義以及某些特定的信息詞，并依據(jù)前文所列舉的四種現(xiàn)象，來判斷此時(shí)須采用的形式。1.Without electricity, human life _ quite different today. A. is B. will be C. would have been D. would be 2.Yesterday Jane walked away from the discussion. Otherwise, she _ something she would regret later. A. had said B. said C. might say D. might have said 答案：DD（二）、時(shí)間錯(cuò)綜句 從句與主句或上下文所表述的時(shí)間不一致。在這種情況下，我們切不可照搬某種形式，而應(yīng)該按照句中所表述的時(shí)間關(guān)系，再選擇相應(yīng)的虛擬形式。例如：If you had worked hard yesterday, you would be tired now.1.If the flower had been watered, it _ now. A. wouldnt die B. is dead C. had been dead D. will not die2.If his television set had not been stolen yesterday, he _ TV now.

Just as in the real world, some people you meet online might try to take advantage of(利用)you.     The key is to keep yourself safe while online. Remain anonymous (匿名的). That means keeping your personal information secret. The people and companies you can trust will never ask for your personal information online. So if someone does, you must be careful.     Think carefully before you create an email address or screen name. Web experts suggest that you use both letters and numbers. In chat rooms, use a nickname (別名) thats different from your screen name. So, if you want to stop an uncomfortable conversation, you can leave and dont have to worry that someone knows your screen name or follow you through email.     Experts suggest that people keep online friendships in the virtual world. Meeting online friends face to face carries more risks than other types of friendships. You can not see or talk with them in person, so its easy for them to pretend to be something theyre not.     If you ever get involved in a chat room conversation that makes you feel uncomfortable or like you might be in danger for any reason, leave immediately and tell your parents or other adults right away so that they can report the conversation.1. Why do web experts suggest using both letters and numbers to create an email address?A. It makes a conversation more comfortable.B. You can exit if you dont want to talk. C. Email addresses can be guessed from screen names.     D. You will not waste a lot of time chatting.2. Meeting online friends has more risks because _.     A. it is difficult to keep online friendshipB. they will learn your personal informationC. the information others give you may mislead you     D. you may feel uncomfortable in a conversation3. The passage mainly talks about _.    A. how to be safe on the Internet for teens B. how to stop an uncomfortable conversationC. how to create a safe email address D. how to keep online friendship     BThe word success means different things to different people. For example, Hector may think success lies in helping others by developing a new medicine to cure a disease. Laura might regard success as being a sports star, while Roz thinks of good grades at school when she thinks of success. Theyre all correct. Success includes all these things, and more.      American poet Ralph Waldo Emerson described success as, "To laugh often and much; to win the respect of intelligent people and the affection of children; to earn the appreciation of honest critics and stand the betrayal of false friends; to appreciate beauty; to find the best in others; to leave the world a bit better, whether by a healthy child, a garden patch, or a redeemed social condition; to know that even one life has breathed easier because you have lived. This is to have succeeded."     Many people consider success as "bigger, faster, better" as in: bigger house, faster car, or better school. Is that really success? Adding to the happiness and success of others is an important part of anyones personal success.     In my opinion, success is learning how to set and achieve goals, how to think of your progress toward reaching them, and the importance of helping others. It means avoiding excuses , taking responsibility (責(zé)任), and learning how to overcome (克服) difficulties. Success lies in answering "yes" to this question: did I give my best effort today?     This is your life, and these are your goals! Try to achieve them as possible as you can.4. Hector, in the first paragraph, is probably a _.     A. sportsman B. student C. Nurse D. scientist4. Which of the following might Tony, a professional ping-pong player, consider to be success, according to the author?A. To become a champion in the Olympic Games.B. To take the responsibility of winning awards.C. To work as a ping-pong coach in a school.    D. To set a goal and to play as hard as possible.5. What is the passage mainly about?    A. The nature of success. B. How to help others succeed. C. How people succeed.    D. The relationship between success and goals.答案重點(diǎn)詞語：1.destination 2.flesh 3. historical 4.pack 5.millionaire 6.smoker 7.non-smoker重點(diǎn)短語：1.plan for 2.depend on 3.help sb with sth 4.have problems with 5.whats more6.in the flesh 7.go on an around-the-world tour 8.not only.but also9.have the chance to do 10.be popular with11.laugh at 達(dá)標(biāo)同步檢測I.1. doesnt finish 2. on 3. will be 4. for 5. to use 6. is 7.wont go 8. will be able to 9. wouldnt have 10.
