Three Students Talk about Museums
三个学生谈论博物馆
Ken: The most interesting museum I've ever been to is the American Computer Museum. They have information about different computers and who invented them. The old computers were much bigger. It's unbelievable that technology has progressed in such a rapid way! I've also learned that there was a special computer. It could play chess even better than humans. I wonder how much more computers will be able to do in the future.
The most interesting museum I've ever been to（我去过最有趣的博物馆）最高级 + (that) + 现在完成时 表示「曾经做过的最……的」。
Amy: I've recently been to a very unusual museum in India, the International Museum of Toilets. I just couldn't believe my eyes when I saw so many different kinds of toilets there. The museum teaches people about the history and development of toilets. It also encourages governments and social groups to think about ways to improve toilets in the future.
I just couldn't believe my eyes.（我简直不敢相信自己的眼睛。）口语常用表达震惊。
Linlin: Last year I went to the Hangzhou National Tea Museum. It's a relaxing and peaceful place near a lake. The tea art performances show how to make a perfect cup of tea with beautiful tea sets. Watching the tea preparation is just as enjoyable as drinking the tea itself. I've finally realized why my grandpa loves drinking tea and collecting tea sets.
Watching the tea preparation is just as enjoyable as drinking the tea itself.（看茶艺和喝茶本身一样令人享受。）as + 形容词 + as = 和……一样。
要点摘要
Ken：美国计算机博物馆——老式计算机大得多，科技进步飞快。
Amy：印度厕所博物馆——种类繁多的厕所令人难以置信，促进厕所改善。
Linlin：杭州茶博物馆——茶艺表演很享受，终于理解爷爷为什么爱茶。

Singapore — A Place You Will Never Forget!
新加坡——一个你永远不会忘记的地方！
Have you ever been to Singapore? For thousands of tourists from China, this small island in Southeast Asia is a wonderful and safe place to take a holiday. On the one hand, more than three quarters of the population are Chinese, so you can simply speak Putonghua a lot of the time. On the other hand, Singapore is an English-speaking country, so it's also a good place to practice your English!

分数表达
more than three quarters of the population（超过四分之三的人口）分数表达：分子用基数词，分母用序数词。three quarters = 四分之三。
Have you ever tried Chinese food outside of China? Maybe you fear that you won't be able to find anything good to eat when you travel. In Singapore, however, you'll find a lot of food from China; you won't have any problem getting rice, noodles or dumplings. Singapore is also an excellent place to try new food. Whether you like Indian food, Western food or Japanese food, you'll find it all in Singapore!
Whether you like Indian food, Western food or Japanese food, you'll find it all.（无论你喜欢印度菜、西餐或日料，都能找到。）whether...or... = 无论……还是……，引导让步状语从句。
Most large cities have zoos, but have you ever been to a zoo at night? Singapore has a Night Safari. It might seem strange to go to a zoo when it's dark. However, if you go to see lions, tigers or foxes during the daytime, they'll probably be asleep! A lot of animals only wake up at night, so this is the best time to watch them. At the Night Safari, you can watch these animals in a more natural environment than in a normal zoo.
watch these animals in a more natural environment than in a normal zoo（在比普通动物园更自然的环境中观察动物）more + 多音节形容词 + than。
One great thing about Singapore is that the temperature is almost the same all year round. This is because the island is so close to the equator. So you can choose to go whenever you like — spring, summer, autumn or winter. And, of course, it's not too far from China!
