您現(xiàn)在的位置: > 大學(xué)英語(yǔ)四級(jí) > genetics genetics的音標(biāo)是[?d?en??t?ks],基本翻譯是遺傳學(xué)。速記技巧可以是將其中的元音字母發(fā)清晰,輔音字母通過(guò)連讀等方式進(jìn)行快速記憶。
Genetics這個(gè)詞源自希臘語(yǔ),意為“自然生成”或“生物的生成”。它的詞源可以追溯到古希臘的哲學(xué)家亞里士多德,他提出了生物的遺傳和變異的概念。
Genetics相關(guān)的變化形式和相關(guān)單詞如下:
1. Genotype(基因型):這個(gè)單詞源自genetics,指的是一個(gè)生物體的基因組成或基因型。Genotype描述的是生物體的基因特征,如基因序列、基因突變等。
2. Genetically(基因上):這個(gè)副詞表示在基因?qū)用婊蚺c基因相關(guān)的。例如,“genetically modified food”(轉(zhuǎn)基因食品)指的是經(jīng)過(guò)基因改造的食品。
3. Genomic(基因組的):這個(gè)單詞用來(lái)描述一個(gè)生物體的所有基因集合。Genomic research(基因組研究)是研究生物體的基因組結(jié)構(gòu)和功能的研究。
4. Geneticist(遺傳學(xué)家):這個(gè)名詞指的是專門研究遺傳學(xué)的人。遺傳學(xué)家研究生物體的遺傳和變異,以及遺傳在生物進(jìn)化中的作用。
5. Genetic engineering(基因工程):這個(gè)術(shù)語(yǔ)指的是利用現(xiàn)代生物技術(shù)對(duì)生物體的基因進(jìn)行操作的技術(shù)。基因工程可以用于改良作物、治療疾病等。
6. Mutation(突變):這個(gè)名詞源自拉丁語(yǔ),意為“變化”。Mutation指的是生物體基因組中發(fā)生的遺傳變化,包括基因突變、染色體變異等。
7. Heredity(遺傳):這個(gè)名詞源自拉丁語(yǔ),意為“傳遞”。Heredity指的是生物體的遺傳特性,即生物體從父母那里繼承的特征。
8. Inheritance(繼承):這個(gè)名詞源自拉丁語(yǔ),意為“被繼承”。Inheritance指的是生物體從父母那里繼承的物質(zhì)、特征或基因。
9. Chromosome(染色體):這個(gè)名詞源自希臘語(yǔ),意為“色帶”。染色體是細(xì)胞中攜帶遺傳信息的結(jié)構(gòu),是基因的主要載體。
10. Genetics laboratory(遺傳學(xué)實(shí)驗(yàn)室):這個(gè)名詞指的是進(jìn)行遺傳學(xué)研究的實(shí)驗(yàn)室。遺傳學(xué)實(shí)驗(yàn)室可以進(jìn)行各種遺傳學(xué)實(shí)驗(yàn),如DNA提取、測(cè)序、突變檢測(cè)等。
常用短語(yǔ):
1. genetic makeup
2. genetic predisposition
3. genetic mutation
4. genetic engineering
5. genetic testing
6. inherited traits
7. genetic counseling
例句:
1. Her genetic makeup makes her particularly susceptible to diseases.
2. The mutation in his genes caused him to be very tall.
3. Genetic engineering has the potential to revolutionize medicine.
4. Genetic testing can help identify diseases early on.
5. We need to have genetic counseling before we have children.
6. She inherited her mother"s beautiful blue eyes.
7. Genetic counseling can be helpful if you have a family history of certain diseases.
英文小作文:
Genetics is an incredibly fascinating field of study that deals with the study of heredity and variation among individuals and populations. It is a crucial aspect of biology that has a profound impact on our understanding of human health and well-being. Geneticists use a variety of tools and techniques to investigate the role of genes in diseases, traits, and behaviors, and they have made tremendous progress in identifying the genes that contribute to various conditions. Genetic engineering has opened up new avenues for treating diseases and enhancing crop yields, while genetic testing has become an essential tool for identifying individuals at risk for certain diseases and implementing appropriate interventions. Understanding genetics is essential for promoting health and well-being among individuals and communities, and it is an area that continues to fascinate and challenge us as we strive to understand the complexities of life.
