Unit 1 Great scientists 单元测试

Ⅰ.阅读理解

A

(2018·天津和平区高三一模)I always had the best intentions of packing my lunch, but putting this healthy habit into practice was a different story. I was always jealous when I would see my co-workers with their cute food containers full of fresh ingredients(食材). Occasionally, I would be inspired to have a productive Sunday afternoon when I would cook my favorite food, but once Wednesday passed, I would be back on the street, trying to figure out what sounded good to eat.

However, to form the habit of packing my lunch is not an easy thing. At first, the idea of packing my lunch felt like a sacrifice, but since I started bringing healthy food to work, I have not given it up. I'm able to bring foods that are rich in fiber and protein, and I avoid ingredients that make my blood sugar rise sharply. This was the big kicker for me to keep this healthy habit for good.

Portion(份量) control has always been a big issue for me. If there is food on my plate, I'm going to eat it. By packing my own lunch, I'm easily able to manage portions and know my ingredient choices. Eating a cleaner and lighter lunch not only supports my general weight-loss goals, but it also makes space for the occasional weeknight dinner out that I can enjoy freely.

When developing my budget for 2017, I made a point to get real about the large expenses I did not even realize. Until I looked at my credit card statement, I had no idea how much money I was spending on my lunch every week. It's hard in the big city to find something that's fresh, nutritious, and filling for under $10.That's $50 a week I could be saving…Quite a sum of money, isn't it?

(2018·山东省实验中学高三摸底)You probably love your dog more than you love some humans. The level of love and trust you feel toward your pet is probably not different from what you feel toward any other family member. But is the feeling mutual(相互的)？5.________ ⅰ.He/She learns your routines.

Trust is understood differently for humans and animals.

ⅱ.His/Her eyes say it all.

When dogs and their owners stared into each other's eyes during a 30-minute period, both of their oxytocin levels increased. Oxytocin has also been called the love hormone and the cuddle(拥抱) hormone.

7．________ And it is produced when we're around someone we love and trust. This result could mean that the dogs were trying to form bonds with their owners—definitely a sign of trust.

ⅲ.8.________

Typically, dogs sleep in a place that they are comfortable, so sleeping in an owner's room could certainly be an indication of comfort. The environment can affect whether your dog settles down in your room or on your bed. However, you may want to carefully weigh your pros and cons before you invite him/her into your bed.

ⅳ.He/She doesn't see you angry often.
