If you put two bottles of water—one hot and the other cold, in a fridge, which will freeze(结冰) quicker? The cold water, right? But in fact, the hot water most probably freezes first. Strange, isn't it? Scientists call it the Mpemba effect(效应).
Once Erasto Mpemba, a school boy, was making ice cream in a cooking class. He was surprised to find that a heated mix froze more quickly than a cold one. He wondered why this happened. When Osborne, a university scientist, came to the school, he asked him about it. It seemed so unbelievable that his classmates laughed at him for asking such a stupid question, but Osborne took it seriously. He suggested that they work together to find out why. They tested many times by using water with temperatures from 25℃ to 90℃, and found that the higher the water temperature was, the less time it took the water to freeze. It means water at 25℃ takes the longest time to freeze and water at 90℃ takes the shortest.
What causes this effect? Some scientists think that the gas leaves water as water heats up, which makes it freeze quicker. Other scientists think differently. They say water in a bottle keeps moving, with hot water rising and cold water going down. This convection is stronger in the hotter bottle, which makes hot water lose heat faster than cold water.
Last winter, the Mpemba effect became popular online. Many people went to Harbin and threw hot water into the freezing air. The hot water would turn to ice at once, allowing people to enjoy the beautiful ice mist(薄雾) in the air. People took videos of this process and put them on the Internet.
(1)、What is the Mpemba effect?A、A study plan. B、A natural guess. C、A scientific finding.(2)、Which of the following can show Mpemba and Osborne's discovery?A、
B、
C、
(3)、What does the underlined word convection" mean?A、The wind in the fridge. B、The force from the outside. C、The movement of heat in water.(4)、What's the purpose of the last paragraph?A、It provides an example of the Mpemba effect in real life. B、It leads to the main idea of the whole text. C、It calls on teenagers to have a try in winter.(5)、What's the best title for the text?A、Ices modern use B、Water's freezing race -

Getting English Language Learners to Put Down the Books and Have Some Fun
Even if there's so much about English that can be learned from a book or even in a traditional classroom setting, a lot of the language can still be learned best in more relaxing situations where students are having fun. Here are some suggestions.
Communicate with strangers.If you live in an area filled with English speakers, get students out of the classroom. Students may not speak to strangers, but they' ll hear conversations taking place and may begin to understand how the words learnt in the classroom are actually used in everyday speech.
Let their guard down. One difficult thing for learners is confidence(自信)when they speak English. Fun activities, especially those outside of the classroom, give students a chance to feel relaxed. It may take a bit of time at the beginning, but once students get into it, they'll start to get confidence.
Make use of English media(媒体). Most recorded language instruction is pretty boring and it can get tiring hearing the same voice repeat the same phrases. They will hear common expressions and more everyday conversations in the movie. If they're not sure about something they hear, it can turn into a more formal lesson once back in the classroom.
Casual(随意的)conversations give learners the chance to hear or use English in situations. They can talk all they want about expressions to use while dining out or informal words to use with friends, but it takes a trip to McDonald's or a picnic in the park for many of those expressions to truly set in.
A. You can let students go to a movie in English.
B. Put them among other English speakers.
C. They may hate to speak English.
D. Hear or use English in situations.
E. They will speak more freely.
