本题可根据沪教版英语六年级下册Unit 2 Changes in our lives中关于数码相机以及过去和现在拍照相关内容的描述来进行判断。
①句描述过去孔先生拍照需要买胶卷，在过去传统相机拍照需要使用胶卷，所以该句正确，答案为T。
②句说数码相机花了他很多钱，根据课程内容可知现在数码相机很常见且价格并非都很高，该句与课文内容不符，答案为F。
③句表明数码相机不需要胶卷，这是数码相机的特点，符合实际情况，答案为T。
④句指在过去照片需要打印并邮寄，过去传递照片确实多通过打印后邮寄的方式，答案为T。
⑤句说现在孔先生只需要通过互联网发送照片，“only”表述过于绝对，但根据课文内容现在可以通过互联网发送照片，该句符合现在的情况，答案为T。

4. 你了解我们国家的巨大变化吗？听一听，填入所缺的单词。
I read a book yesterday. It was an interesting book. It told me many in our lives in China. For example, people rode horses or walked to a faraway place. But now, people can a car, take the train or the plane to a faraway place in a short time. In the , people used brooms to sweep the . But now, use the street sweeper. The computer is another great invention. People used pens and paper to letters or books. But now, people use computers to do that. I there will be more changes that make our lives easier and better.

1. changes；2. drive；3. past；4. street；5. they；6. write；7. think

本题主要考查对课文内容的理解和记忆，需要根据上下文的意思填入合适的单词。
1. “It told me many...”后面应该接表示变化的复数名词，“changes”符合题意，表示“它告诉我中国生活中许多变化”。
2. “people can...a car”这里需要一个动词，“drive”有驾驶的意思，符合人们驾驶汽车去远方的语境。
3. “In the...”这里根据上下文推测是说过去的情况，“past”表示过去，“In the past”是固定短语，意为在过去。
4. “sweep the...”这里需要一个名词，“street”表示街道，人们过去用扫帚扫街道符合文意。
5. “...use the street sweeper”这里缺少主语，根据语境应该是人们使用清扫机，“they”可以指代前面提到的人们。
6. “write letters”是固定搭配，意为写信，人们过去用纸笔写信或书。
7. “I...there will be...”这里需要一个动词，“think”有认为、想的意思，我认为将会有更多改变使生活更好符合语境。
