Most foodies (吃货) agree that eating healthy food is important. But sometimes making good food choices can be tough. Now, there are apps that can help people learn about the food they eat to improve their diets and their dining out experiences. Cheese & Wine Pairing app

Wine and cheese can be a great combination. But which wines go best with which cheeses? Max McCalman’s Cheese & Wine Pairing app can help. It provides information about hundreds of different cheeses and advises wines to pair with each. Max McCalman’s Cheese & Wine Pairing app is free for iPhones and iPads.

Calorific app

What does 200 calories look like? It can be hard to picture. Calorific provides images of 200 calories worth of food. The pictures can help people on a diet and those who just want to eat healthier food. The app is free for iPads and iPhones. There is also a version that provides more information for a price.

HappyCow app

Vegetarians(素食主义者) do not eat animal meat. Vegans(严格的素食者) do not eat any animal products. The HappyCow app is made for both groups. Users can search for vegetarian-vegan restaurants and stores around the world. A free version of HappyCow is available for Android that has ads and requires an Internet connection. LocalEats app

Restaurant chains, like McDonald’s, can be found almost anywhere a person might travel. But sometimes travelers want to eat like locals. LocalEats is designed for that. It lists locally owned restaurants so users can try foods from that area. The app costs about a dollar.

Do you always agree to do things that you are unwilling to do? Are you the type of person who always says “yes” ? I’ve come to learn that it is very important to learn to say NO! It’s okay. People are still going to like you. They may even respect you more because they know you are honest.

I'm not saying to say “no” to someone who really needs your help. I'm talking about refusing that meeting that you really do not want to attend or that birthday party that you don’t want to be a guest at.

Think for a moment how you feel when you say YES to something that you really don’t want to do. If you’re like I once was, you can’t sleep at night and you think about it too much. It weighs on your mind. You try to find ways out. Whatever you’re saying to yourself, if you really wanted to go, you wouldn’t have all of these thoughts.

So, why not just say NO from the beginning? Maybe you feel like if you don’t show up at the meeting (by the way, it is not the one you must attend) your boss isn’t going to like you or your co-workers won’t respect you. Maybe you feel as if your mom, dad or sisters won’t love you as much if you don’t do everything for them that they ask every occasion.

If these people are your true friends，family members，or a good boss，they will like or love you the same no matter what. People treat you the way you teach them to, and if you’re someone who always says “yes”, then that’s what they’re expecting.

You need to do what is right for you. Of course we do have real obligations(义务) in life to fulfill, but we do not have to do everything others want us to do.

24.Which of the following statements would the writer agree with?

A. We should try to do what our friends ask us to do.

B. We should help others in need.

C. Always saying “no” means you are brave.

D. Always saying “yes” means you are dishonest.

25.What does the underlined word “ It” in Paragraph 3 refer to?

A. Saying “yes”.

B. A friend’s birthday party.

C. Something you’re unwilling to do.

D. Something you think difficult to do.

26.The writer believes that if you say “no”to your family members, you’ll ______.

A. upset them

B. disappoint them

C. have a loose relationship with them

D. have the same relationship with them as before

27.What would be the best title for the passage?

A. Learn to Make a Right Choice

B. To Be Yourself

C. Learn to Say No

D. Do What You Want to Do

Charlie is a teacher and his wife, Maria is an artist. The night before last, just before the longest day of the year, Charlie was sitting in a deckchair enjoying the warm summer air when Maria touched his shoulder and he could tell immediately she was a little worried about something. He asked her what the matter was and she replied that there was a strange thing on the jacket that was hanging in the bedroom. They had both lived in the West Indies (西印度群岛) and had seen a lot of strange creatures in their house before. But now they were living in England and so Charlie just laughed and said he would have a look at the “thing”.

He walked to the bedroom. He saw a jacket hanging in the bedroom and went up to

it to have a closer look at the “thing”. The moment he touched it, the thing sprang into life. Now Charlie experiences fear and when this creature opened its wings,

he jumped out of his skin and ran screaming from the room like a small child doing about 100 miles an hour.

For a moment the next-door neighbors thought that Charlie was murdering his wife because of the noise they could hear. In fact, it was a bat that frightened Charlie.

Eventually Charlie managed to trap the bat in a box and took it to the garden

to let the bat fly. Maria, who had been playing the guitar while Charlie was upstairs, asked Charlie if he had found out what the thing was. “Oh, nothing to worry about”,

he said casually hoping that the terror could not be seen in his eyes, “it was just

a bat.”

28.Why was Maria a little worried one night?

A.Because she couldn't find her guitar.

B.Because she saw something strange.

C.Because it was too hot for her.

D.Because she had quarreled with her husband.

29.The underlined part “jumped out of his skin” in the second paragraph probably means ____.

A.stood up

B.was very frightened

C.threw off his clothes

D.was very excited

30.What happened to the bat?

A.It was killed by Charlie.

B.It was badly wounded.

C.It was set free by Charlie.

D.It was kept as a pet.

31.It can be inferred that ________.

A.Charlie was afraid that his wife would laugh at him if she knew the truth.

B.the neighbors would report to the police about Charlie murdering the bat.

C.the bat wouldn't come to Charlie's room again because it was frightened.

D.Maria heard her husband screaming downstairs and became frightened.

Every summer, the Serengeti plains(平原) of Africa are worth visiting. Millions

of wild animals begin their 1,800-mile journey northwards on their annual migratory (迁移的) route.

In the month of November, polar bears in their thousands cross the Canadian Arctic, as they head towards the ice sheets of Hudson Bay. The sea ice that forms every winter is the key to the bear’s managing to exist, for here they hunt for seals (海豹).

The Great Bustard, one of the heaviest flying birds, migrates each year across Europe and Asia to its wintering grounds. Unluckily, these and other migratory animals are in danger from human activity.

We have written several articles on climate change and the effect of rising ocean temperatures. Since 1979, ice sheets in the Arctic have gone down by 30 percent. What does this mean for polar bears? They are forced to stay on land for longer periods of time, which delays their search for food. As a result, bears today are 60 pounds lighter than what they were. Besides, smaller bears also produce weaker babies, and their chances of survival are at risk. In the plains of Africa, migratory animals like gazelles are traveling long distances for food, just to avoid falling prey (牺牲品) to humans who hunt them.

In an unusual step, experts from 120 countries have agreed to protect 31 migratory mammals, fish and birds. The United Nation’s 11th annual Conservation of Migratory Species of Wild Animals (CMS) was held in Quito, Ecuador. For the first time, 900 experts attended the conference, and the enthusiastic support shows the world is united in conservation (保护) efforts.

What does getting on a protected list mean? Countries that have signed the agreement will be required to pass laws locally and work with other countries that fall within the animal’s migratory path. Only one animal did not make the list. The African lion was rejected (拒绝) for lack of information of the countries where it lives.

32.What can we learn from the passage?

A.The Great Bustard is one of the largest flying birds.

B.The weight of polar bears today is lighter than what it was.

C.In the 1970s, ice sheets went down by 30 percent.

D.120 experts have agreed to protect 21 migratory animals.

33.Why was the African lion not included in the list from the passage?

A.We don’t know which countries it lives in.

B.It isn’t a migratory animal.

C.Experts were not interested in this animal.

D.It was not traveling long distances for food.

34.The writer writes this passage aiming to __________.

A.let us know about the animals

B.prevent the rare animals from dying out

https://www.wendangku.net/doc/d84195669.html,rm us of the effects of climate change

D.draw our attention to helping the migratory animals

35.All these factors have probably put the migratory animals in danger EXCEPT _______.

A.some human activity

B.the enthusiastic support from experts

C.rising ocean temperatures

D.climate change

Dear Tom,

I’m sorry to hear that the COVID-19 has broken out in your country. Asked about how I studied in the epidemic situation in the e-mail, I’m writing to share some details with you.

To begin with, I had to study online at home via a powerful APP named Ding Talk, through which I attended classes and handed in my homework. It is certain that studying online has advantages and disadvantages. For example, I could watch the videos of lessons after class if I didn’t understand some difficult points. However, I found it upsetting that I couldn’t interact with the teachers effectively. What’s worse, studying online did harm to my eyes, because I had to keep staring at the computer screen from day to night.

As far as I am concerned, studying online is the best way to continue the courses during the epidemic situation. If you want to know more, please don’t hesitate to write to me again. Looking forward to your reply.

Yours sincerely,

Li Hua
