A new study has found the amount of antibiotics(抗生素)given to farm animals is expected to increase by two-thirds over the next 15 years.Researchers are linking the growing dependence on the drugs to the increasing need for meat,milk and eggs.However,the drugs could quicken the development of antibiotic-resistant infections(感染).Such infections are already a major public,health concern in the United States.
The World Health Organization notes when people stop living in poverty(貧困),the first thing they want to do is eat better,rather than earn more money.For most people,that means their diet should contain more meat.With the rapid development of Asia,people there are eating nearly four times as much meat,milk and other milk products as they did 50 year ago.
To meet the need,farmers have put many animals into smaller spaces.As the animals are crowded together,the easiest way to deal with some of the problems d crowding is to give them antibiotics.It's clear that antibiotics help animals stay healthy in a crowded environment and grow faster.But bacteria can develop resistance to the drugs gradually.
Nowadays,doctors find antibiotics that once worked against the infections no longer work.The bacteria have learned ways to fight against the drugs.The heavy use of antibiotics in animals is responsible for the growth of antibiotic resistance worldwide.In the United States,at least two million people get drug-resistant infections each year and at least 23,000 die from an infection.
Europe has banned the use of antibiotics to increase animal growth.And the United States is hoping to persuade farmers to stop using antibiotics for that purpose.
1.What accounts for the increasing amount of antibiotics given to farm animals?
A. The desire for new drugs. B. The less effective antibiotics.

Imagine the tallest building in the United States. Fill that large building 44 times with rotten (腐爛的)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 ________.

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

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 (加強(qiáng)) 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.
