Unit 7 The natural world
A Verbs and sentence structures (Ⅱ)
Some verbs can take two objects, a direct object and an
indirect object.
S+V+O (indirect)+O(direct) ——→ The sun gives
ocean animals light and heat.
S V
O O
We can change the order of the direct and indirect objects by using to or for.
The sun gives light and heat to ocean animals.
We should build a better home for local wildlife /'wa ldla f/.
TIP
These verbs are often used with to:
give hand lend offer
pass post read sell send
show take teach tell write
An object complement can also follow a direct object to give more information about the object.
S+V+O (direct)+C ——→ The mother bird keeps the eggs safe.
They call the ocean the ”heart“ of the earth.
We made the forest the topic /'t p k/ of this class.
S V O C
We can add an adverbial to the structures above. We use
an adverbial to show when, where or how an action is done.

TIP
These verbs are often used with for:

make order pick prepare save
A1 Amy is writing about the desert. Read her writing and write the main structures of the underlined sentences using S+V+O+O or S+V+O+C.
The desert
Deserts are difficult places for animals to live. Little rain and too much sunshine make deserts dry. Many desert plants give animals water. These plants store the water in their leaves.
S+V+O+C
S+V+O+O
Some animals feed on the leaves and the water can keep them healthy. Quite a few desert plants also give animals food. Their flowers and fruit can provide animals with energy.

We use conjunctions like and, but, or and so to join ideas together.

With more than two expressions, we usually only put
and before the last.

Oceans provide food for many animals, produce oxygen
and store heat from the sun.
We use but to join ideas that are different.
This kind of fish can find enough space here. They can
find little food.

can find little food.
We use or to introduce another possibility.
Birds can live in the forest. They can also live in the wetland.

In negative sentences, we use or to join two or more ideas.
