What are the most poisonous(有毒的)animals in the world?

The box jellyfish is widely regarded to be the most poisonous animal whose toxin(毒素)can cause heart attacks.

Cobras, typically found in the jungles of India and China, can kill somebody in a very short time and just 7ml of their venom is enough to kill 20 humans.

The marbled cone snail is a sea creature and its venom is so poisonous that it can result in vision loss(视力丧失), respiratory failure(呼吸衰竭),muscle(肌肉)paralysis(麻痹) and finally death. To make things worse, there is no anti-venom available.

Poison dart frogs are small and brightly coloured but the toxin in its body can cause paralysis and death.

Puffer fish are considered to be a dangerous delicacy(美味佳肴)because some of their anatomy(部位)contains a dangerous toxin which, if ingested(摄入)in a large quantity, can cause convulsions(抽搐),paralysis, cardiac arrhythmia(心律失常),and finally death.

The Brazilian wandering spider, also known as the 'banana spider', has venom so high that it can cause paralysis and death.

Death stalker scorpions have a fitting name as enough venom from one can cause a lot of pain and respiratory failure.

阅读下面的短文,根据短文后的要求答题。

What does it mean to be a Chinese? According to a survey, more than 40% of Chinese people believe the Chinese love the country and their family. At the same time, about 1/3 of foreigners describe the Chinese as hard-working and creative people.

From 1931 to 1945, millions of soldiers lost their lives in the war against Japanese aggression. (A) And after the founding of the People’s Republic of China, plenty of people, including scientists and workers, worked day and night for the development of China.

While the love for the country joins the people together, family plays a big role in traditional Chinese culture. “My Chinese friends get married and have babies when they get to a certain age. And Chinese friends think about their family first when they choose a job or give up one.” said Aaron Cedillo, an English teacher in a school in Beijing.

(B) , the characters of being hard-working and creative are also well-known. Sherry Wang, Malaysian student, used the package delivery(快递)on weekends as an example of how hard- working Chinese people are. “It seems those men never need to rest.” she said. A foreign university professor has found some Chinese students in the lab could always come up with new ideas. “I'm really surprised.” he said.

The past seventy years witnessed(见证)China’s rapid development. During the process, the international community, including Chinese people themselves, have got a clearer understanding of Chinese characters.

1.What do some of the foreigners describe the Chinese according to the passage? (根据短文回答问题)

_______________________________________________________________________

2.Put the underlined sentence(A) into Chinese. (请将文中划线句子译成汉语)

_______________________________________________________________________

3.B处横线上填上合适的单词,使句子意思连贯,语法正确(不超过3个单词)。

________________________________________________________________________

4.从文中找出与下面这句话意义相近的句子。

China has developed very quickly in the past seventy years.

______________________________________________________________________

5.给文章拟一个恰当的标题。

________________________________________________________________________
