once out of the earth's gravity,the astronaut is ____by the

glass litter (玻璃废弃物 ),center of gravity（引力中心）,
belt litter（带状废弃物）,glass rail（玻璃栏杆）

物体的重力把物体拉向地球中心

答案：B
翻译：大家都认为,降落的水滴所受的重力把水滴的圆形改变成泪珠的形状.
解释：从句意来看,选项必须做定语去修饰shape,以和后面的shape对应.
所以用名词所有格形式,排除AC.
第二次出现drop,所以用定冠词the最佳,排除D.

虚拟语气,不是单复数问题.

在近地轨道上,向着远离地球的方向,重力以0.33 μg/m渐渐减小.可是我觉得重力的单位不对劲儿,怎么是 μg?是不是由于在太空中重力加速度很小,我们把质量直接等同于重力了?我是个文科生,有人告诉我吗?

　　how mcuh gravity is pulling you　为现在进行时,这种时态句的谓语部分是两部分构成,即am/is/are+现在分词,这两部分缺一不可,只有这样才能使所在句子谓语部分完整,不然句子成分残缺,有严重的语法错误.

Gravitation ,also known as gravity or gravitational interactions (China often referred to as gravity,Taiwan and more occasions in physics called gravity).
In physics,gravitation or gravity is the quality of the objects have accelerated between the near trend.That the gravitational interaction of gravity is a natural one of the four fundamental interactions,the other three interactions are electromagnetic interaction,weak interaction and strong interaction.Gravity is the force of these interactions with the most feeble,but in the ultra-distance on the role of gravity is still attractive.In classical mechanics,the gravity is considered from the force of gravity.(Gravity that gravity is also often used as a synonym for gravitation or gravity).In general relativity,the gravity comes from the existence of the quality of space-time distortions,rather than a force.In quantum gravity,the gravitational force was assumed to be sub-micro-gravity medium of transmission.[1]
In the face of the earth's gravitational attraction given the weight of objects and their whereabouts to the ground.In addition,the gravity is the Sun and Earth and other celestial bodies of the reasons why there; there is no gravity to attract each other celestial bodies will not be able to form a celestial body systems,and forms of life as we know it will not occur.Gravity at the same time so that the Earth and other celestial bodies in accordance with their own orbit around the sun,the moon in accordance with its own orbit around the Earth,the formation of tides,as well as other we have observed a variety of natural phenomena.

重量是引力作用于物体的力

重力只在物体本身动的时候起作用
英语句子对
物理方面 是错的 物体静止时 重力也起作用吧

既然是脑筋急转弯问题,可以理解为:
"gravity"这个单词的中心是什么?
数一下,中间的字母当然是"v".

A_尽管,引导让步状语

1)比重是某物质的密度与水的密度之比.
2)in the 1940's 和 in the 1940s都表示“在20世纪40年代”的意思.in the 1940 ；in 1940's ；in 1940s都为错误表达；而in 1940就是“在1940年”的意思.

d
be located 位于 固定搭配

其实加不加-都可以,现代英语一般不加-

B

重力的大小取决于什么
depends on =取决于

B
后面的those指代前面的things,意思是因为不同引力作用,火星上的东西比地球上的（东西）轻.

主要是修饰Enery这个词的一致性要求.简单地说,这里比较的是：
the energy expended in traveling from the Earth to the Moon
vs.
the energy expended in traveling from the Moon to the Earth.
你可以尽量把后者(the energy expended in traveling from the Moon to the Earth),但是不能简化到“断章取义”的程度,你就会发现E才是对的了.

gravity的中心是什么?
智力题吗?
答案是V.V字母是这个单词的中心.,考难我了.

这是to do 不定时作主语的句子
真正的句型是：To understand why there is gravity is hard.由于主语太长,有些头重脚轻.
所以,说英语的人们常这样说：
It's hard to understand why there is gravity.
不是强调句

直译：人体的重心定位于关节/沟通之后.
意译：生命在于运动.
（PS：身体健康关键在于沟通与运动,当一个人加入群体或运动后人体身体得到锻炼/心情愉快,从而利于身心健康,定位人生.）

重力只有当物体向下移动时才起作用.

句子不完整.可以这样说：
Do you think if/whether love is stronger than gravity?
你认为爱比地心引力更强吗?
If love were stronger than gravity,how would the world be?（此句用虚拟语气）
假如爱比地心引力更强,那世界会是什么样子呢?
希望对你有所帮助.

是要求英译还是回答问题呢?
意思是“真实土壤微粒的相对密度约为2.65吗?”

答案是错的.
其实你查查字典就知道答案了.

Yield有以下意思：
vt.
1.生产；尤指
1)生产,生长出(作物),结出(果实)：
2)(作为报答而)给予；(作为结果、利润等)产生：
2.[有时作yield oneself]被迫放弃；屈服,投降；放纵；沉湎于,沉溺于(有时与up连用)：
3.给予,让与；统一,准予：
4.[古语]付酬；酬报,回报
5.【棒球】失(分)
vi.
1.生产；产生；结果实：
2.放弃；屈服,投降；让步,退让：
3.(对外方)屈从：
4.让位于；被…所取代,失去优先地位、领导权等(常与to连用)：
5.(在力量、重压等下)屈曲；倒塌；垮掉(to)：
The small chair yielded under his weight.
那个小椅子被他压垮了.
n.
1.生产,出产,收益
2.产量,收益量；产物；劳动报酬；投资利益,利润；税收
3.【财政学】投资实得率,收益率；年收入率
4.【物理学、化学】
1)产量,产额,产率
2)当量(在一次核爆炸中所释放的有效总能量)
所以问句中的含义,应该取vi.的第5个意思：(在力量、重压等下)屈曲；倒塌；垮掉
整句话的翻译可以是：
对地球重力场的研究表明,地壳和地幔在受到其上方不正常的重量时会垮塌.
