昨天的大雨阻止了我们去野餐的英文是：The heavy rain yesterday prevented us from having a picnic.这句话里面还包含了一个动词搭配：prevent sb. from sth.阻止某人做某事。由于这里的时态为过去式，所以作为谓语动词的prevent要加ed变成prevented。其中from为介词，have a picnic的have是一个动词，介词后面的动词要变成动名词形式，所以have要去e加ing。希望可以帮助到你~

avoid 避免，避开，躲避，消除prevent预防，防止。 强调事先采取行动预防

只能帮你到这了，打开翻译词典。具体的看一遍稍作修改。Prevention is the most effective means to prevent and reduce traffic accidents. Prevention is ideological vigilance, and more importantly, preventive measures, equipment, technology and staffing. Preventive measures are to take precautions in the future and eliminate all factors that are not conducive to driving safety in the budding state. When driving under any circumstances, we should keep a clear mind. We should carefully analyze and correctly judge the situations that may affect the safety of driving, and take corresponding measures at any time so as to be ready and safe. Firmly establish the idea of safety first and prevention first, firmly establish the idea of safety first, have a high sense of responsibility for people"s lives and national property safety, take seriously their special occupation, drive cautiously, regulate driving, and ensure the safety of passengers, goods, pedestrians and their own, which is not only the premise of completing the transportation task, but also the basic requirement of automobile transportation. It can be said that there is nothing without safety, and the importance of safety is determined by the position of safety in automobile transportation. As an automobile driver, only if we have a sufficient understanding of this importance can we consciously carry out the idea of safety first and prevention first. Therefore, drivers must cultivate good habits of conscious compliance with the law, civilized driving, not running red lights, driving at medium speed, not driving heroic cars, not driving after drinking, not driving sick cars. Therefore, I always take some time to study traffic laws and regulations, automobile drivers and other books conscientiously, and learn from the effective experience of safe driving in learning by doing. By combining practical experience with books, I can broaden my knowledge, deepen my understanding and apply it more deeply. It"s easy to add. It is the key to avoid traffic accidents to firmly establish traffic safety awareness. Violation of regulations is the hidden danger of accidents. Accidents are the result of violations. This is a blood lesson. Peers should bear in mind that traffic accidents are caused by speeding, illegal driving, inattention, poor driving skills, poor driving conditions, unsafe road conditions, pedestrians and passengers. 2. Drivers must have market-based driving skills in order to continuously improve driving technology and safety. Efforts should be made to study business, strengthen learning, master common sense of safe driving, constantly sum up experience of safe driving, especially through analyzing accidents happened by others, to learn lessons, guide driving practice, correctly handle the relationship among people, vehicles and roads on the road, and constantly improve driving technology, so as to ensure driving safety. 3. Experience checking and maintenance vehicles, people are in good working condition, people are lazy and break down. As a driver, only by checking and maintaining the vehicles, can we drive safely and create more economic benefits. Therefore, no matter how busy and tired the work is, the vehicles should be carefully checked. Before leaving, we should check the steering system, brake system and lights, horns, wipers and rearview mirrors for completeness and effectiveness, whether the bolts of the transmission system are loose or not, and do a good job of vehicle cleaning, so as to have a good idea. In driving, we should pay attention to the working condition of each instrument, check whether there is any abnormal noise, stop immediately when abnormal phenomena are found, find out the reasons, and eliminate the faults in time. Summarize one day"s driving experience, eliminate hidden dangers, prepare for the next day"s driving, keep the vehicle in good technical condition and lay a good foundation for safe driving. It can be seen that consciously abiding by the rules and regulations, establishing safety awareness and keeping the car in good condition are the key to prevent and reduce accidents. It is very worthwhile and extremely important to replace safety with prevention. Safety is a blessing! It"s the greatest economy.

protect sb from doing sth这里的from不能省略。protect...from…是表示保护。。。不受伤害。from后接能带来伤害或损害之物。所以是：Protect sb/sth from sth/doing sth例句：You had better wear sunglasses to protect your eyes from the sun.Hair can protect our heads from being hurt.注意：prevent sb from doing sth与stop sb fromdoing sth用法相同，在主动语态中from可以省略，被动语态中不行。keep...from在表示此意时，from不可以省略。keep。。。doing 是使。。处在。。状态中的意思。如果没有了from就变成了keep sb doing sth了，意思就反过来了。

没有区别，都表示“阻止某人/某物做某事”后接动名词。前两个的from可以省略，后一个不能省略。省掉就变成了“让，，不停地做某事”。如：The heavy snow prevevted/stopped/ kept us form going out.大雪阻止我们出行。They kept the buy running.他们让那小孩不停的跑。

遇见，满足另外表示的一些“偶然遇到”词组有：comeacross,runintomeet的用法:Imetyourgirlfriendearliertoday.(met是meet的过去式，此处表示遇见)meetyourneeds（表示满足需要）
