       His new book “The Shallows: What the Internet is Doing to Our Brains” suggests the latest technology makes us less able to think deeply. Carr found he couldn’t concentrate and that he couldn’t work on the book while staying online.
       “So I was only checking my email a couple of times a day rather than every 45 seconds. I found those types of things really did make a difference.” he said.
       After at first feeling uncomfortable with his sudden loss of online connection, within a couple of weeks, Carr was able to stay concentrated on one task for a longer period.
       His book also examines the history of reading and the science of how using different media changes our brains.
       Reading on the Internet has greatly changed how we use our brains, he writes. Facing a lot of texts, photos, videos, music, text messages, emails and blogs, our minds have become used to skimming(略读) and scanning(跳读) information. As a result, we have developed skills at making fast decisions, Carr says. But now most of us hardly read books, long articles that would help us concentrate, Carr writes.
       Carr says for centuries books helped focus our minds on one topic at a time. He has a suggestion for those who feel web surfing has left them unable to concentrate——slow down, turn off the Internet and practice the skills of being deep in thought.

5 . 阅读下面短文，在空白处填入一个适当的词，或填入括号中所给单词的正确形式。

I went to a restaurant for lunch with my grandpa yesterday, and when the starters came, I took out my phone and took some photos of them. My grandpa felt very     1     (surprise) and he laughed at me. “Food is for eating!” he said. “Why are you taking photos of it?”

He even didn’t know why. So I told him, “All my friends take photos of food in restaurants to share on social media (媒体), and when we’re deciding which restaurant     2     (go) to, we look at photos people post on social media. Before I go to a restaurant, I also look at photos on social media to see the food on the menu. So when I arrive at the restaurant, I know     3     I’m going to eat.”

Then, my grandpa     4     (choose) mushroom soup for his starter, and I ordered baked cheese because it looked delicious in a photo on my phone. Either of the     5     (dish) was very good. We finished our starters and then grandpa looked at the menu for the main course. He couldn’t decide     6     a fish dish and a beef dish. “Would you like to see some photos of them?” I asked. He laughed again. “OK,” he said.

I got out my phone again, found the photos and gave him the phone. He decided the beef looked much     7     (nice) because it came with rice and broccoli.     8     same thing happened with the desserts. After the meal, I asked grandpa, “Will you use photos on social media to choose your food next time you eat out?” “Maybe,” he said. “If I’m with one of my grandchildren!”

When I got home, I looked at the photos     9     I took during the meal. They were     10     fantastic that I couldn’t wait to share them!
