• Read the texts about five people working with animals and the questions below. For each question choose the correct person. The people may be chosen more than once.

   

A. Veterinary surgeon – Seb Prior

Seb sees a huge variety of creatures in his role as a veterinary surgeon. He says, “Anything can come through the door; you just wouldn’t believe it. We do general pet care and, because the clinic’s so close to a road, I spend lots of time dealing with animals who’ve been hit by cars. I spend half my day in the clinic and a half doing operations, which is a nice mix. I like being able to get out and reach people – being able to talk to them and answer their questions is a huge part of the job. You can be the best surgeon in the world but if you can’t talk to the clients, that’s a huge problem. You need patience and understanding for the people and the animals.”

B. Wildlife assistant – Wendy Burrows

Wendy sees all sorts of animals, from garden birds to tiny hedgehogs and fully-grown swans and every day is different, but Wendy’s wildlife center is particularly busy during the summer months. She looks after up to 500 hedgehogs and their young, who have to reach a certain weight before they can be let go into the wild. Wendy says, “It’s always a lovely moment when this happens, one of the most satisfying parts of the job”, but if this isn’t achieved by September, the hedgehogs have to be kept at the center over the winter period.”

C. Animal care assistant – Anna Lindley

Anna Lindley cares for a wide range of animals, from dogs and cats to birds and mice and it is these smaller animals that give her the greatest satisfaction. “Ever since I was a child, I’ve loved animals and I hate it that we often don’t pay attention to the small ones.” Caring for such a range of animals provides an interesting challenge and plenty of work! “With so much to do, I find myself rushing from job to job and never quite keeping up. I love the fact that you never know what you’re going to get, although unfortunately, that does mean I sometimes have to deal with a snake, which I find a bit scary!”

D. Inspector – Justin Stubbs 

“Becoming an animal inspector was something I’d always wanted – along with being a policeman. At first, I had no idea what it involved but actually, the job is better than I ever imagined. There’s never a day when I don’t want to go to work. The job is a lot harder than people realize and it can get me down at times. Over the years I’ve had to learn to put it to the back of my mind when I leave at the end of the day, but that’s easier said than done and it’s true to say that a bit of the job always comes home with me. It’s the nature of the job.”

E. Vet nurse – Naomi Killingsworth 

Naomi works with people as much as animals but not everyone who comes through the hospital doors is as grateful as you might think, as Naomi explains: “Sometimes I wish more people appreciated what we do. We work hard here, but not everyone realizes that. Of course, there are also many people who couldn’t be more grateful for what we’ve done to help their animals – they make it all worthwhile.”

 

+ QUESTIONS:

1, Which person is pleased with their schedule at work? ___________

2, Which person says their job was a childhood ambition? ___________

3, Which person does a job in which the amount of work varies?  ___________

4, Which person always looks forward to going to work? ___________

5, Which person says communication is an essential skill for their work? ___________

6, Which person is disappointed by some people’s opinion of their work? ___________

All creatures neeed to eat something in order to survive. Fortunately, different species of animals have different things that they eat as food. No matter what a creature eats, the food must have enough calories in it to maintain life. Calories, or the energy stored in the food, provide the fuel which animals, including humans, need in other words enough calories, will starve and die.

            The term calorie has a scientific meaning. Calorie is a measure of an amount of energy just like pound is a measure of weight. A calorie is officially defined as the amount of energy it takes to raise the temperature of a gram of water by 1 degree Celsius, which is 1.8 degrees Fahrenheit. The terrm “ calorie” and “ Calorie” with a capital C have two different meaning to scientists. The term Calorie ( with a capital C ) means one kilocalorie, the amount of energy required to raise the temperature of one kilogram of water by one degree Celsius. A kilogram is the same as 1,000 grams and a kilocalorie is 1,000 calories. Food calories are always measured as Calories but average people don’t care much about the difference and just use the word calories.

            Food is composed of proteins, fats and carbohydrates. Nutritionists know that a gram of protein contains 4 Calories, a gram of fat has 9 Calories, and a gram of carbohydrate has 4 Calories.

            All food contain calories. When we eat something it provides energy for our bodies to use when we are active. We even need energy or calories while we are sleeping because, for example, our bodies are still breathing, our heart is pumping, and we continue to digest the food in our stomachs. If a person eats more foodand more calories than is used up by activity, the body stores the excess calories in case it might need it later when food might not be available. So a person gains weight due to the extra food and calories. Similarity, if a person consumes fewer calories than are used every day over several weeks and ismore active, that person will lose weight.

1. Calorie is a measure of ............................

A. weight                   B. distance                  C. energy                D. volume

2. Animals that do not consume enough calories over a long time .........................

5. You read an article in a magazine about food and nutrition that uses the term “ calories ”  What kind of calories is this article talking about ?

A. the amount of energy               B. energy            C. foods                  D. protein, fats and carbobydrates

6. All the following statements are true EXCEPT ......................

A. Eating foods that contains lots of fat cause a person to gain weight faster than eating protein

B. People normally pay less attention to the difference between “ calorie” and “ Calorie”

(Đọc văn bản. Nối các từ được đánh dấu với nghĩa của chúng.)

There are two types of community service. The first one is a kind of punishment. For example, people who litter may be forced to clean up the streets. In this case, they may not feel happy about the work. The second type of community service is voluntary. This means people are willing, or pleased to do the work. For instance, people may volunteer to build houses for poor people, or raise money for children in mountainous areas.

However, it does not mean that volunteering is always a selfless act because volunteers may also benefit from the volunteering activities. For example, they may volunteer to meet new people, to develop social skills, or to find themselves' (learn what they truly want in life). In general, people may volunteer not just to help others, but also to help themselves.
