() 4.______ healthy food and ______ some exercise ______ good for us.
A.Have; do; is
B.Having; doing; are
C.Have; do; are
D.Having; doing; is

D

动名词短语"Having healthy food"和"doing some exercise"并列作主语，视为整体，谓语动词用单数is。选项D符合。

() 5.Wearing red can make ______ for you to take action.
A.that easily
B.this easier
C.it easily
D.it easier

D

本题主要考查形式宾语的使用以及“make”后接形容词作宾语补足语的用法。在英语中，当动词后接不定式（to do）作宾语，且不定式带有较长的宾语补足语时，为了保持句子结构平衡，常使用形式宾语“it”来代替不定式，而将真正的不定式置于句末。同时，“make”作为使役动词，其后常接形容词作宾语补足语，表示“使……变得……”。观察选项，A项“that easily”和B项“this easier”均不能作为“make”的宾语补足语，且没有使用形式宾语；C项“it easily”中“easily”为副词，不符合“make”后接形容词的用法；D项“it easier”中“it”作为形式宾语，代替后面的不定式“to take action”，“easier”为形容词比较级，作宾语补足语，符合语法规则。

() 6.I hear ______ the professor will come back from the USA soon.
A.which
B.what
C.that
D.whether

C

hear后接宾语从句，从句"the professor will come back from the USA soon"结构完整、意义明确，不缺成分，应用that引导，that在从句中无实际意义可省略。which表示“哪一个”，what表示“什么”，whether表示“是否”，均不符合语境。

四、任务型阅读
There are many colours in nature. But do you know that a colour has weight? I think you'll say "no". But I am afraid you are wrong. If you don't believe, you may do a small experiment(实验).
First, put two objects with the same weight into two boxes. Then cover the box. Third, wrap(包裹) one box with a red piece of paper, the other with a white piece of paper. OK. Now hold the boxes with your hand one by one. It is certain that you will think the red one is a little heavier.
Why do you think so? A scientist found that different colours have different weights in a man's mind. So he did some tests and at last he got the result. That is to say, every colour has its own weight in our mind and their order is the same. The heaviest colour is red, then blue, green, orange, yellow and white.
The scientist told us that colours also have smell. Can you smell the colour? Of course not. Then why did the scientist say so? That is because every colour stands for a kind of light with a certain wavelength(波长). It reaches our brain through sense organs(感觉器官).
According to this discovery, scientists say that people accept the colours they like, and refuse the colours they hate. So your body and mind will be healthy by using the colours you like, or you'll be nervous or even get ill. For example, if you stay in a room with red windows, wallpaper and furniture for two hours, you'll feel you have been there for four hours. But if the room is blue, you'll feel you have been there for only an hour. Another example is that if a person walks out of a red room and into a blue room, his temperature will fall. That means our body temperature will change with different colours.
| Discoveries | Examples | Reasons |
| Colours have 1 . | You may feel the red box is 2 than the white one, though they have the same weight. | Every colour has its own weight in our 3 . The heaviest one is 4 and the 5 one is white. |
| Colours have senses. | • The colour you like can make you 6 .• You'll feel time passes much 7 in the red room than in the blue one.• The colour will cause the 8 of your body temperature if you go from a red room into a blue one. | The 9 wavelength of each colour makes us feel the 10 of the colour. |
