Animals seem to have the sense to eat when they are hungry and they do not eat more than their bodies need. It has been shown that rats will, when given a choice over a period of time, prefer water with vitamins(维生素) to water without vitamins even though there is no difference in taste or smell between the two water bottles. When a fragrant flavor was added to the vitamins-enriched water, the rats did seem to develop it and kept drinking it, even after the vitamins were switched to the clear water. In time, however, they broke the habit and went back to where the necessary vitamins were.

In a classic experiment, babies of 6 to 12 months old were placed in a cafeteria feeding arrangement, with a wide selection of baby food before them. They were given whatever food they pointed to or appeared interested in. We are told that at first they showed some unusual eating patterns, but over a period of time they managed to select well-balanced diet.

So, in choosing food, rats and babies do seem to know and act on what’s best for them. Apparently, there is a kind of “body wisdom”, which humans soon lose. Most of us do not eat as wisely as we could. Many of our food preferences are culturally determined and influenced by long-formed habits. Some people eat foxes, dogs and blackbirds, while we eat cows and pigs. So what people eat and how much they eat seems to be greatly influenced by what is going on around them.

1.In the experiment on rats, a fragrant flavor was added to the rats’ drinking water to _________.

A. test whether rats know which drink is good for them

B. encourage rats to drink vitamins-enriched water

C. find out rats’ preference in flavor

D. demonstrate the vitamins are tasteless

2.According to the passage, adults eating habits differ from those of babies because _________.

A. adults know better than babies what kind of food are good for their health

B. adults’ eating habits are closely related to the social and cultural customs

C. adults have more choices of food than babies in eating patterns

D. adults usually cannot resist the temptation of various delicious foods

3.As far as their eating habits are concerned, babies and rats are similar in that ________.

A. both prefer flavored food and drink

B. both have the same eating patterns

C. both have the wisdom to choose a balanced diet

D. both develop a taste for the same kinds of flavors

Imagine the tallest building in the United States. Fill that large building 44 times with rotten (腐烂的)fruits and vegetables．Now you know how much food Americans waste every year．

It is hard to believe, right? About 133 .billion pounds of food get .thrown away. That's one, third of all the food we produce. And a lot of it is thrown away for one simple reason: It's ugly.

The problem is that nature isn't perfect. Apples can get scarred(留下疤痕)by storms. Cucumbers grow in C shapes. Carrots change into unusual fork-like forms. Watermelons get too big to fit on a refrigerator shelf. These crazy-looking fruits and vegetables may .taste great. But most grocery stores refuse to sell them. Store owners say people judge food by how it looks. No one wants a tomato that looks like a two-headed monster. (怪物). But what if you could buy that tomato for half-price?

A new movement is trying to make people see the "beauty" in ugly food. Some stores are selling ugly produce. It tastes the same. And you pay less for it because the. food doesn't, look perfect.

Usually, the stores find a nicer word than "ugly'; A Canadian chain uses "naturally imperfect". In some US stores, it's "misfit produce". Whatever you call it, ugly food helps many .people. Farmers get paid for food they were going to have to throw away. Shoppers get cheaper fruits and vegetables. The ugly-food movement will also help some of the 44 million Americans who don't have enough to eat. Many groups give the ugly produce to hungry people.

So really, who cares if that carrot looks a little ... ugly?

1.We can know from the text that ________.

A. food is thrown mostly because it goes bad

B. food waste is a serious problem in America

2.What is the "beauty" in ugly food?

A. It tastes the same but costs much less.

B. It does much good to people.

C. It is useful to hungry people.

D. It tastes just as good as normal-looking produce.

3.The ugly-food movement is intended to ________.

A. call on people to help the poor

B. persuade grocery stores to sell ugly produce

C. prove the value 0fugty produce

D. advise people not to waste food

How to love your Mondays

I used to spend the second half of Sunday dreading Monday morning.1.But now I am definitely in the “I Love Mondays” camp. Here’s what I’ve found that works:

Start Monday morning with your Sunday night routine. When you get ready to exercise, you warm up first.2. Get everything you need for the morning ready to go. Then consider a special “Sunday Night Only” winding down ritual (固定方式).It might be tea and a favorite TV show, or a long hot bath. Whatever it is, enjoy this Monday morning warm-up, and consider turning in a little earlier than you’re used to.

3.Turning in a little early Sunday night can help with getting up a little early Monday morning. When you have a little extra time in the morning, you can gently settle into the day and keep that weekend feeling of ease as you start your new week.

Find a theme for the week. Every Monday, I post an inspiring quote or saying on the wall. These are intentional! Each week, as part of my Sunday night winding down time, I consider what I’d like to focus on in the coming week, and look for a quote that’s a good fit to reinforce (加强) it.4.

Look at the week’s tasks as opportunities instead of problems. What are you excited about for the new week?5.What’s been hanging over your head undone from last week? Take a look at the week ahead and highlight a few things that you can reasonably accomplish.

When you are intentionally creating a life you love, Mondays begin to feel like a beautiful new start!

A.Get up early enough to start slowly.

B.What a waste of a perfectly good evening!

C.What problem-solving opportunities do you have?

D.Consider Sunday nights your warm-up for Monday.

E.Have them in clean, working order and a convenient location.

F.It can be a word or whatever inspires you for the week ahead.

G.The work is the same either way, but our attitudes are within our control.
