“Mosquitoes are more likely to bite people with type O blood (O型血).” Have you heard someone say this before? It’s not true!

I’m not very picky (挑剔的) about blood types. In fact, I cannot tell which blood type you are. Only doctors can do that. So how do I choose who to bite?

I can smell the carbon dioxide (二氧化碳) on people’s breath. The more you breathe out, the more easily I can find you. This means larger and fatter people are more likely to get my “kiss”.

I can also find food by smelling. You play outside and start sweating (出汗) all over. I can smell the lactic acid (乳酸) in your sweat. So yummy!

I also use my eyes to find food. But my eyesight (视力) is not very good. If you are trying to avoid me, do not wear colors such as black, red or dark blue.

It’s only females who have a taste for blood. They need it for their eggs. Male mosquitoes do not bite. For a proud mosquito mother, not just any blood will do.

1.Mosquitoes cannot _____

A.smell anything B.tell blood types C.see anything D.breathe

2.Mosquitoes are more likely to bite people _____.

A.who wear white clothes B.who are short and thin

3.What do we know about mosquitoes?

A.Male mosquitoes live on carbon dioxide.

B.Mosquitoes like strong and sweet smells.

D.Only male mosquitoes bite  people.

4.What can we learn from the text?

Now I know that we black people are much more likely to have high blood pressure and diabetes (糖尿病) than white people. And they often lead to heart attacks and other untreated diseases. For example, black people are three to four times more likely than white people to have high blood pressure and twice as likely as the white population to die of a stroke (中风).

New research has found out the surprisingly high levels of salt in many of black people’s favorite meals. I stopped putting extra salt in my food at the table long ago and I try to cut down on the salt. I use in cooking. The suggested daily level of salt for adults is 6 grams. It is easy to see that if you try not to eat too many processed (加工过的) foods and use salt in your cooking within the limit, you won’t reach more than the daily level.

The research showed how much salt there is in some foods that we buy from restaurants and takeaways. An average salad with rice and peas has 6.2 grams of salt. This is more salt than you are supposed to eat for the whole day.

A researcher talked about the importance of home cooking rather than take-outs. At home, he pointed out, not only can you hold control of the salt bottle, but also you can create tasty food which is low on salt. The researcher later provided curry goat and rice and peas. They were low on salt, but completely delicious.

I do not suppose Jamaicans are going to stop buying takeaways soon. But if you suffer from high blood pressure, it is probably better not to buy them often.

1.The underlined word “they” in Paragraph 1 refers to _______.

A．white people                          B．black people

C．untreated diseases                      D．high blood pressure and diabetes

2.What has the new research found out according to Paragraph 2?

A．Black people take in too much salt.

B．Black people’s meals are very special.

C．Processed foods have too much salt in them.

D．6 grams of salt per day is enough for an adult.

3.What would the writer probably suggest black people do?

A．Order no salad in a restaurant.             B．Take in no salt for several days.

C．Stop cooking their favorite meals.           D．Eat less takeaways.

4.The researcher provided curry goat and rice and peas in order to _______.

A．thank those who came to his home for his research

B．let people know that eating less salt makes one healthier

C．show that tasty food with less salt can be made at home

D．prove the less salt the food has the more delicious it is

5.What would be the best title for this passage?

A．Watch the salt                          B．Take care, black people

C．Say no to takeaways                     D．Say no to high blood pressure

九年级英语单项填空中等难度题查看答案及解析

A Bite of China is a program with the rich culture and history about Chinese food. Besides introducing many kinds of delicious food across the country, it also shows Chinese society by explaining how these dishes came out and they are made, the relationship between people and food and a little Chinese philosophy(哲学). The first and second seasons were great successes. However, the third season was seen by viewers as a huge disappointment.

Criticizing(批评) the latest eight­section program has already become hot online. Criticism has mainly focused on two points: inaccurate or controversial(有争议的) content and the method of storytelling.

The program mixes up “Malatang” and “Chuanchuanxiang”， two different types of local spicy dishes in Sichuan Province. What's more controversial is that in one section “medicine and food come from the same origin(起源)，” which advises people to put traditional Chinese medicine into dishes without mentioning the risks.

As for the storytelling of the program, the new season has focused more on people's life stories than food. Criticism reached the top after one section, in which not traditional “Shuaimian (hitting noodles)” but the personal story of a chef who struggles to make a living in the big city was introduced in detail. It's surprising that a food program would ignore the food itself.

A change in the program team may be one of the reasons. The team said, “When the first season was put on, there were only about 40 food programs in China. But now the number is around 500. People's expectations are changing.” There are reasons for this opinion, but it's believed that “the devil is in the details”．

1.A Bite of China is a program including rich ________ about Chinese food.

A.politics B.geography C.history D.art

2.What shows the third season is inaccurate?

A.Chinese food contains some philosophy. B.“Malatang” equals to “Chuanchuanxiang”．

C.Medicine and food are from the same origin. D.“Shuaimian” can be called hitting noodles.

3.The underlined word “content ” in the passage means “________” in Chinese.

A.评论 B.事物 C.内容 D.理论

4.What's the reason for the failure of the third season?

A.Too many similar programs. B.Audience's high expectations.

C.The first two seasons' success. D.Lack of the eagerness for perfection.

5.What is the main idea of this passage?

A.To introduce a popular TV program.

B.To let people know Chinese traditional culture.

C.To show people's love of this TV program.

D.To describe some opinions on the TV program A Bite of China.

Social media(媒体)is a big part of most people’s lives. There are social apps and sites like WeChat and Sina Weibo, as well as video apps like Douyin and Kuaishou. How do you behave when you use these apps?

Recently researchers at the University of Sussex, UK, studied social media users ranging from 10 to 15 years old. They found that they can be divided into four personality types.

Geeks(极客)

Geeks are active social media users，but they find it mush more difficult to deal with the life in the real world. Most of them are boys who like playing computer games and making music and videos.

This group prefers WeChat over Sina Weibo, as WeChat has private groups. They can’t express themselves well but at least they make sure to protect their personal information.

Victims(受害者)

People use languages to communicate. Any language has its ways to express people’s minds. One of the ways in common is the use of idioms. An idiom is a group of words. It has a special meaning that is different from the usual meaning. For example, under the weather is an idiom meaning ill. So when people say “I’m under the weather," they are saying that they’re not feeling well. Another example, in all weathers means in all kinds of weather. So, “There are homeless people sleeping on the streets in all weathers" tells us that homeless people sleep on the streets no matter whether it is cold or hot.

Different languages may have different ways to make idioms. For people who are learning a foreign language, idioms could cause misunderstandings and bring them endless headaches. On the other hand, if things are done right, idioms can also be a fun way of looking into a new culture and understanding how the people think and talk.

Metaphor (比喻) is often used in idioms. Let’s read the following two examples:

● It makes my blood boil (煮沸) when people litter.

● The night was dark and quiet; my blood ran cold when I heard a strange noise outside at dark night.

In neither situation above, our blood can reach the point so high or so low in temperature. Yet, with the situations the two sentences created, it is not difficult to work out the unhappy feelings of really angry in the first example and very afraid in the second.

Of course, not all idioms are this easy to understand. When we come to idioms of a foreign language, a good dictionary of idioms is always suggested.

1.This passage tells us something about __________ in the English language.

A.grammar B.writing C.reading D.idioms

2.If your brother breaks your computer, you can say to him, “__________.”

A.I’m under the weather B.I’m there in all weathers

C.You’ve made my blood boil D.My blood runs cold

3.What is the writer’s advice when you come to an expression like under the weather?

A.We should look it up in a good idiom dictionary.

B.We should try to express our minds with it.

C.We should find an interesting way to learn it.

D.We should create situations to guess its meaning.

Have you ever wondered what goes through your mind when you choose where to sit in a new classroom? Or in a waiting room full of strangers? Or on a bus? Researchers have found out some interesting facts.

Perhaps unsurprisingly, we prefer to sit closer to people like ourselves. Girls sit by girls and boys sit by boys. Adults sit together and young people choose another young person to sit near. But it goes further than this. We even choose to sit near someone who looks like us. People with glasses are more likely to sit near other people with glasses. People with long hair sit closer to other people with long hair.

We seem to believe that people with similar habits or hobbies will share similar attitude and we are more likely to be accepted by people like ourselves or even, we think we may be safer with people who look like us. Sometimes that’s true but it's a pity if we always stick to the same people, the same group. The danger in always staying in our comfort zone (舒适区)is that we just recycle the same opinions, the same tastes and the same ideas. We lose the chance to learn something new, find out about interesting things, hear funny stories and discover difference.


When we always stick to the same people, how can we ever break down the barriers which prevent us from getting to know people with different ideas? And how can we avoid the ignorance (无知),which too often leads to prejudice (偏见) and even fear? If instead you want to live in a society that opens to changes and new things and different opinions, be the cat among the pigeons.

Move out of your comfort zone. Go and sit next to someone different. And don't just sit there in silence. Say hello. Ask a question. Start a conversation. That’s how we make friends. That’s how we learn about people. That’s how we open our minds to new ideas. That's how we live an exciting life.

1.From the passage, we know that people prefer sitting by someone who________.

A.is like themselves

B.has a sense of humor

C.is open-minded

D.lives an exciting life

2.People like staying in their comfort zone because they may________.

A.remain comfortable and special

B.be accepted easily and feel safe

C.find out more interesting things

D.discover differences among themselves

3.What is the purpose of the passage?

A.To tell us just to be ourselves in social life.

B.To introduce ways to learn about the world.

C.To explain how people communicate with others.

D.To encourage us to meet people of different kinds.
